On the Oregon coast, NOAA and partners are leveraging the strong engineering skills of their beloved state animal to restore important habitat for threatened coho salmon and other species.

Supported by NOAA, our partners at the Wild Salmon Center and Upper Nehalem Watershed Council are embarking on a pilot project. It will assist beavers with building dams in key areas of tributaries where juvenile migrating fish grow. Once built, beaver dams create slower moving sections of streams for juvenile fish to use as habitat.

To construct the beaver dam analog, a row of wooden posts is anchored upright in the stream bed.

Similar to estuaries and river delta habitats, the slow-moving pools of water behind beaver dams offer juvenile salmon critical time for feeding and growing before their trip to the ocean. Unlike man-made barriers to fish passage, adult salmon are able pass beaver dams when they migrate back upstream to spawn.

With these pilot projects, NOAA and partners are building foundation structures, called “analogs.” They are placed in areas where beavers once lived, and where the stream grade and size are optimal for juvenile salmon habitat. Think of them as the foundations of a home.

The slow moving pools of water created by beaver dams provide habitat for threatened coho salmon and other species.

Once we introduce the analogs to ideal areas, beavers find them and build out the rest of their new homes. Rows of wooden posts intertwined with tree branches and straw give our furry restoration partners a solid foundation from which to start building their dams. We also ensure they have plenty of food sources by planting willows and other tasty foods beavers like while removing invasive plants from the areas.

These innovative but simple projects are turning back the clock to times where beavers freely built dams along streams and rivers in Oregon watersheds. Modern development has straightened stream channels and increased the amount and speed of water flow. This makes it hard for juvenile salmon to rest during freshwater stages of their early lives. This habitat loss for beavers and salmon has created population declines for both species.

These pilots are one piece of a larger effort, the Oregon Coast Coho Recovery Plan, to restore Oregon Coast coho salmon habitat. We are providing funding and technical support to the Wild Salmon Center to implement a series of habitat restoration projects across the Oregon Coast. We are working with a variety of partners including local and state governments, non-profit organizations, tribes, and other federal agencies. Together these coordinated efforts are targeting restoration where it will have the greatest benefit and make the biggest impact for threatened coho salmon.

Native Trout Species Returned to an Appalachian Stream

Hundreds of Tennessee’s Only Native Trout Species Returned to an Appalachian Stream
from The Fishing Wire

Native trout being restocked in Tennessee


Chattanooga, Tenn. – Winding under a thick canopy of trees and down a stairstep of boulder-strewn waterfalls, Little Stoney Creek’s descent through Cherokee National Forest is the idyllic picture of Appalachian Mountain splendor.

With its dappled pockets of sunlight and shade and frigid water, this pristine stream is an ideal habitat for Southern Appalachian Brook Trout. Also lovingly referred to by scientists and sport fishers alike as “Brookies,” this region-specific strain of Brook Trout is the Southeast’s only native trout species.

With blue skies patchily peeking through the trees overhead, Tennessee Aquarium Conservation Institute Reintroduction Biologist Meredith Harris and Reintroduction Assistant Hayley Robinson carefully navigate the stream across moss-slick rocks and trees.

Their progress through the rushing stream is made all the more difficult thanks to the shifting weight of the thick plastic bags they’re carrying. These awkward burdens are filled with water and — most importantly — dozens of two-inch long juvenile Brookies bound for reintroduction into the creek after months of attentive care at the Aquarium’s freshwater science center in Chattanooga.

Harris and Robinson, along with two other reintroduction assistants, Avery Millard and Anna Quintrell, have traveled hundreds of miles to reach this beautiful, remote waterway. Along with representatives from the Tennessee Wildlife Resources Agency, the U.S. Forest Service and members of Trout Unlimited, the biologists have convened to return 389 juvenile Brookies to waters that are their ancestral birthright.

“You know, today is the day when we really get to see what it’s all about,” Harris says, smiling. “It’s a great day; it’s the best day.”

Despite the treacherous footing, she and Robinson are all smiles as they slosh along, pausing occasionally by patches of comparatively still water. Dipping into their bags, they deposit nets full of baby trout into these calmer pools. As they watch the tiny fish swim away, their expressions mix equal measures of pride and joy.

“We work really hard back at the facility and spend a lot of time working with these animals,” Harris says. “To be able to come out here and watch them swim away into the water, to fulfill the ecological role that they were meant to, that’s what makes it all worth it. That just really brings the purpose home for me.”

Thanks to clear-cutting in the 1900s and the introduction of larger, competing, non-native species like Rainbow Trout and Brown Trout, the ruby-bellied and golden-speckled Southern Appalachian Brook Trout now occupies less than 15 percent of its historical range.

Since the 1980s, the Tennessee Wildlife Resources Agency has been working to restore the Southern Appalachian Brook Trout to cold water streams like Little Stoney Creek that flow through the species’ native range. In 2012, the Tennessee Aquarium Conservation Institute joined this effort, helping to raise the juveniles in propagation facilities at its freshwater science center near downtown Chattanooga.

Each fall, Conservation Institute biologists collect eggs spawned by a broodstock of wild-caught adult Southern Appalachian Brook Trout. During a month-long incubation, scientists tend to these eggs until the young emerge, still attached to large, nutrient-rich yolk sacs. After another month, these “sac fry” become free-swimming and are able to eat.

Biologists care for these juveniles throughout the winter and early spring until the diminutive fish are about two inches long, just large and hardy enough to survive in the wild. Including the current batch of juveniles, the Aquarium has raised and reintroduced about 3,500 Southern Appalachian Brook Trout to Little Stoney Creek and other waterways.

This effort is fully financed by the Appalachian Chapter of Trout Unlimited through funds raised by the sale of special vanity license plates adorned with the Southern Appalachian Brook Trout. In 2018, Trout Unlimited donated $11,170, the organization’s largest single grant since it began financial support of the program in 2014.

“The Tennessee Aquarium is a natural partner for us,” says Steve Fry, the chapter’s president. “The mission of Trout Unlimited is to conserve, protect and restore North America’s coldwater fisheries and their watersheds. This project allows us to coordinate efforts with Trout Unlimited Chapters in northeast Tennessee to bring back an iconic species.”

At Little Stoney Creek, representatives from the Overmountain Chapter of Trout Unlimited are wading alongside Harris and Robinson, enthusiastically accepting offers from the biologists to release some of the fry. To them, Brookies aren’t just another fish to try and catch; they’re a part of the region’s natural heritage.

“The Southern Appalachian strain of Brook Trout is the only trout species in this area that God put here himself,” says Overmountain Trout Unlimited Chapter President Ryan Turgeon. “A lot of different organizations came together to raise funds, and a lot of grant money and hours were put in to get something like this done.

“It’s great to see everyone come together — different age groups, different diversities — to return these fish to the stream. It was really great to see that.”

Why Don’t They Stock Bass in Big Lakes?

Why don’t they stock bass in this lake so we can catch more? I am often asked that question by fellow fishermen, and I have an answer, based on what Georgia state fisheries biologists have told me and what I have read in magazines and books.

note – I wrote this several years ago. There is now some evidence stocking Florida or hybrid strain largemouth, in suitable habitat lakes, can improve the size of bass in the population but not necessarily the numbers. But without suitable habitat, it will not work, no matter what is stocked.

When you build a new pond you normally stock it with bream, then wait until after they spawn and stock bass and maybe catfish. The bream spawn every month in the spring and summer and quickly fill the pond with small bream. They will increase in numbers until they are using all the food available. Without predators like bass, they will never grow very big because there just is not enough food to match their prolific population increases.

Bass eat bream, so they will keep the population in check. But the bass will also produce so many offspring that they will eat too many bream, causing them to run out of food and be stunted, too. That is why you should remove bass from your pond on a regular basis.

Fish will expand to fill the available space and food resources. In big lakes some species overpopulate and cause problems. Good examples are gizzard shad and blueback herring. They don’t have a lot of natural predators in our local lakes since they are and open water fish and get too big for most bass to eat. They can get so thick in lakes that they cause disease outbreaks and use up food resources.

When that happens, fisheries biologists look at stocking fish that will eat the shad and herring. Stripers and hybrids are stocked for this reason, and also to give fishermen something fun to catch. The stripers and hybrids are good choices because hybrids are not fertile and can not reproduce, and stripers can’t reproduce in most of our lakes due to limited miles of flowing water. So their numbers can be controlled.

Stocking of stripers and hybrids can be overdone, too. No matter how many you put in, the total numbers that survive are limited by food available. In an 11 year study on Smith Mountain Reservoir in Virginia it was found that stocking 200,000 stripers each year resulted in the same numbers surveying after one year as stocking 620,000 each year. There simply was not enough food to support more, so the extra fish died.

In a big lake largemouth bass usually fill all their niche naturally, reproducing to produce numbers that take advantage of space and food resources. Adding small bass will do nothing to add to the numbers of bass since they are already using up all the available food and space. The maximum numbers are already there.

There are some exceptions, of course. In the Flint River below Lake Blackshear dam the water changes levels several feet every day due to power generation. Shoal bass living from the dam to Albany can’t be very successful spawning since their beds are either too deep for the eggs to hatch or shallow enough for the eggs to hatch but left high and dry when the water drops.

The state is stocking fingerling shoal bass in this area since natural reproduction can not keep up. It can’t keep up because man has altered the habitat.

In north Georgia at Lake Nottely, fishermen that thought they knew more than the fisheries biologists stocked blueback herring. Blueback herring are a great baitfish for bass – for a time. But the little herring eat the same things as largemouth fry, and big herring will even eat little bass fry.

There is not much cover on Nottely to allow the little bass to hide, so a lot of them are eaten. Due to the huge numbers of blueback herring that have resulted, largemouth bass populations have crashed.

Nottely is the only lake in Georgia where largemouth bass are being stocked, and it is a very special situation. Fisheries biologists study each lake and determine what is best for it. If appropriate, bass will be stocked, but stocking bass in most lakes just uses up money and resources that are needed in other areas, and does nothing to increase cacheable bass numbers.

I am glad we have professional fisheries biologists to take action based on science to improve our lakes.

Stable Snapper Season

Amendment 50 Gives Gulf States Stable Snapper Season

By DAVID RAINER
Alabama Department of Conservation and Natural Resources
from The Fishing Wire


Big Red Snapper


After a three-year struggle, saltwater anglers are on the cusp of a stable red snapper season with the approval of Amendment 50 by the Gulf of Mexico Fishery Management Council.

Amendment 50, which goes into effect in 2020 with the approval of the Secretary of Commerce, gives the five Gulf states control over each state’s snapper season, and it allows leeway in size and bag limits within certain federal guidelines.

“All of the Gulf states are excited to finally have this solidified and move forward with the management plans for the individual states,” said Scott Bannon, Alabama’s Marine Resources Director. “It’s a win for the red snapper stock and a win for the states.”

Bannon said state control of the snapper fishery was brought before the Council in 2016 to manage the recreational sector, which would have included the private recreational sector and the federal for-hire (charter) sector.

The 2016 and 2017 snapper seasons were painfully short under federal control. As a way to alleviate the impact on anglers and the Gulf Coast economies, the Gulf states were issued an exempted fishing permit (EFP) for the 2018 and 2019 seasons, and states were able to set their seasons under a total allowable catch for each state.

Alabama originally set its 2018 season at 47 days, but near-perfect weather and an increased enthusiasm for catching the state’s signature saltwater species forced Marine Resources to reduce the season to 28 days, which ended in an almost perfect catch-to-allocation result.

The way Alabama was able to ensure there was no significant overrun on the quota was through the Red Snapper Reporting System, more commonly known as Snapper Check. The mandatory reporting system allowed Marine Resources to monitor the catch and close the season in response to the larger-than-expected harvest numbers.

The success of the Snapper Check monitoring paved the way for the Council to approve Amendment 50.

“I think the fishery benefits from Amendment 50 because we have the ability, as individual states, of not exceeding our allocation of the quota,” Bannon said. “If you look at it from a stock perspective for the Gulf of Mexico and you were managing it as a whole and you had a perfect season, like last year, you had no way to put the season in check. Alabama alone would have consumed nearly half of the entire Gulf allocation if we had fished the whole 47 days. We would have fished it really, really hard, and the amount of fish we would have caught would have been tremendous. As it was, we closed it when we met the number of pounds and showed that we were responsible. I think this is much better for the anglers and the snapper stock. I think the EFP showed the states could come to some decisions about allocations, and that the states could manage seasons within pretty close tolerances.”

Bannon said the Gulf Council faced two challenges with state management of red snapper. First, where do the federal for-hire boats fit into the program? The Council decided to not include the federal for-hire in Amendment 50 and consider other options in the future if conditions change for the federal for-hire boats. Second, what allocations could the five Gulf states live with?

“These allocations were based on different factors like biomass and historical landings,” Bannon said. “So, the state directors used the EFP allocations as a starting point for Amendment 50.

“The EFP only allowed us to set the season within our allocation. Under Amendment 50, we received an increase in allocation from 25% to 26.298%, and that increase will be permanent. We also have in Amendment 50 the ability to set size and bag limits within certain parameters. Those are management tools to maximize the benefit for Alabama.”

When the initial EFP allocations were proposed, the totals did not equal 100% of the total allowable catch. Bannon said Florida was given the extra 3.78% because they were the final state to apply.

“They amended their EFP to get that extra allocation,” Bannon said. “We felt like that extra allocation should be negotiated. In the end, Alabama and Florida split that 3.78% under Amendment 50 because we’re the two largest consumers of red snapper. The other states were comfortable with that. It seems to be fair and equitable.”

Under the new amendment, each state creates their own plan. Alabama’s plan includes a 10% buffer as opposed to the 20% buffer under the federal system. The federal for-hire sector has not exceeded its quota for several years, and its buffer was reduced to 9%.

Alabama’s allocation of red snapper for the 2019 private recreational season under the EFP is 1,079,765 pounds. Alabama’s allocation for the 2020 season increases to 1,122,661 pounds if the private recreational sector doesn’t exceed its quota this year.

Bannon said most red snapper anglers are happy with the upcoming season, and he anticipates there could be some season adjustments when Amendment 50 goes into effect.

“Most of the responses I’ve received for the 2019 season is they were happy to get the June and July seasons and that the season was spread out enough that if the weather was bad they could go another weekend,” he said. “We know we still have concerns from the public that they would like more fishing time during the week. As we move forward in state management, that is always a possibility because we now have the flexibility to set the seasons.”

The 2019 season length is tentatively set for 27 days, starting June 1 with three-day weekends (Friday-Sunday) except opening weekend (two days) and July 4 week, which will be four days (Thursday-Sunday). The size limit and bag limit remain the same at two fish per person with a minimum size of 16 inches total length.

Bannon is planning to ask snapper anglers for assistance to keep Alabama’s unparalleled artificial reef program at the top. The loss of funding for research in those reef zones will prompt him to ask the Conservation Advisory Board to implement a reef fish endorsement beginning in 2020.

“The reef fish endorsement is set up to help fund some of the research conducted in the reef zones, because we’re losing some of the funding used for that research,” he said. “The research needs to continue, and we also need funds to support programs like Snapper Check, which we hope to expand into a better program.

“It’s designed as a user-based system that applies to the people who are participating in that fishery, including private recreational, charter for-hire and commercial fishermen. Another aspect of it is it defines the user group. It gives us a better idea, especially among private anglers, of how many people are fishing for reef fish off Alabama. That way we can have better directed surveys, which are targeted at people who participate in the fishery instead of just people who have saltwater fishing licenses.”

The endorsement fees would be $10 for private recreational anglers and $250 for commercial fishermen. The charter for-hire fees would depend on the size of the boat and number of passengers the vessel can carry.

As for Amendment 50, Bannon said Alabama has already shown state management will work. The public is supportive, and he thinks that Secretary Wilbur Ross will quickly approve.

“As I said on the radio the other day, Alabama has 3% of the Gulf coastline and will receive 26.298% of the total allowable catch for the 2020 season and beyond,” Bannon said. “I think Amendment 50 is a success for the fishery, and I think it’s a success for the states because the states can now manage the seasons, size limits and bag limits that best suit their anglers.

South Florida’s Bonefish Nurseries

Conservation of South Florida’s Bonefish Nurseries

Bonefish fry need protecting


When we think about promoting a healthy bonefish fishery we often turn our attention to protecting large schools of adult fish patrolling the flats. Often forgotten are the more vulnerable juvenile fish, those less than three inches long, that must survive a constant barrage from predators and a chaotic, rapidly changing environment. Nowhere are the challenges faced by juvenile bonefish more evident than in the Florida Keys.

Over the years we have seen a decline in the Florida Keys bonefish population, and an unusual absence of juveniles. The cause of this decline is still unknown, but it has coincided with changes to freshwater discharge in South Florida, increases in coastal development, and higher frequency of extreme weather events. These disturbances may be responsible for negatively impacting important nursery habitats and at least partially explain the bonefish population decline.

Nurseries are potentially the most important and complex habitats that a fish will occupy during its life. They provide protection from predators, abundant sources of food, and environmental conditions that allow for fast growth and an increased chance of survival. And since juvenile bonefish are too small to move to better habitats, taking the nursery habitat away is like pulling a table cloth out from under a castle of cards; the castle will fall.

BTT collaborating scientists have identified nursery habitats in the Bahamas, where thousands of juvenile bonefish are found in shallow, seagrass-free areas that are sheltered from strong waves. In the Keys, we have checked these types of habitats and have found only a handful of juveniles. Healthy juveniles are the future of the fishery, and we are teaming up with researchers at Florida Atlantic University’s Harbor Branch Oceanographic Institute to figure out where juvenile bonefish are settling in the Florida Keys. Here is what we know so far about juvenile bonefish in the Keys:

1) Juvenile bonefish should be most prevalent in the early summer, following the winter through spring spawning season.

2) We recently learned that Bahamian juvenile bonefish use sandy or muddy bottoms with little wave action. Similar habitat in the Florida Keys is rare, and so far our sampling of these types of habitats has captured very few juvenile bonefish.

Identifying and protecting essential fish habitat is the first and most important step towards recovering the bonefish population in the Florida Keys. Once we identify bonefish nursery habitats, we can work with county, state, and federal managers to designate these habitats for protection. With a better understanding of the environmental characteristics that make for quality bonefish nurseries, we can work to restore degraded habitats, so they can become functional nurseries again. The future of the bonefish fishery may depend on the success of our habitat conservation efforts.

What you can do to help:

The search for juvenile bonefish in a region as expansive as the Florida Keys requires substantial time and effort. As a community we can work together to find juvenile bonefish and protect them when they’re most vulnerable. If you have encountered juvenile bonefish while fishing or cast-netting in the Florida Keys, Florida Bay, or Biscayne Bay, please contact our project lead:

Dam Removals Help Fish

Decades of Dam Removals Help Fish Reach Historic Homes

Herring swimming upstream

From NOAA Fisheries

In the United States, more than 2 million dams and other barriers block fish from migrating upstream. As a result, many fish populations have declined.
For example, Atlantic salmon used to be found in every river north of the Hudson River. Due to dams and other threats, less than half of 1 percent of the historic population remains. The last remnant populations of Atlantic salmon in U.S. waters exist in just a few rivers and streams in central and eastern Maine. They are an endangered species.

Reduced fish populations affect the entire ecosystem, since they are often important prey for other animals. They are often crucial to commercial and recreational fisheries, so reduced numbers can impact local economies as well.

NOAA Fisheries and cooperating agencies have been removing many of these barriers in recent years.

Town Brook in Plymouth, Massachusetts, once full of barriers blocking migrating fish from passing, has been reopened and restored. Now fish like river herring and eels can make it to and from habitats important for their survival and sustainability, and they are better able to support ocean species that rely on them for food.

Click to visit our story map for a virtual walk along Town Brook seeing 20 years of fish passage work.

The 1.5-mile stream flows from the freshwater Billington Sea to the Atlantic Ocean near Plymouth Rock, Massachusetts, and serves as an important habitat for fish that migrate between the ocean and freshwater areas. For hundreds of years, dams in the stream blocked fish from passing and caused populations to decline.

The NOAA Restoration Center worked with its partners, the Town of Plymouth, State of Massachusetts, and others to remove these barriers to reopen the stream. The first dam was removed in 2002, and as of 2019, five dams have been strategically removed and major improvements to fish passage have been implemented at the sixth dam site. The final, Holmes Dam, was removed just in time for the annual spring herring run.

Removing the Town Creek dam

Every year, millions of fish migrate to their spawning and rearing habitats to reproduce. Some fish swim thousands of miles through oceans and rivers to reach their destinations. Often blocked by human-made barriers, when fish can’t reach their habitat, they can’t reproduce and grow their populations.

NOAA Fisheries removes or finds ways around barriers to fish passage and improves in-stream habitat for migrating fish. We have completed more than 600 fish migration projects, opening almost 6,000 miles of rivers and streams.

Florida Shuts Down the Big Three of Inshore Fishing

Florida Shuts Down the Big Three of Inshore Fishing on SW Coast

from The Fishing Wire

Florida’s Fish and Wildlife Conservation Commission (FWC) made a pre-emptive strike on restoration of inshore fish on the state’s southwest coast devastated by red tide–and shocked many anglers–by moving to shut down all harvest of the Big Three of Florida fishing, snook, redfish and spotted sea trout. The closure, which begins May 11 this year and continues until May 31 of 2020 as it now stands, will likely have a significant financial impact on guides, bait shops, fishing-oriented resorts and tackle and kayak and boat sales to say nothing of individual recreational anglers–but will be very good for the fish.

It won’t be the first time one of the state’s premiere fisheries has been shut down to allow recovery–in 2010 after a massive winter kill of snook, the commission shut down all take for almost three years.

Millions of adult fish were killed in the most recent red tide, which extended from November 2017 to early 2019, 15 horrendous months. Countless tens of millions more fry-size fish as well as the bait all gamefish feed on were also wiped out.

While some estuarine areas where the tide did not reach remain very good–or even better than before in a few places because the noxious water pushed fish off the coast and well up the bays to escape–others like Sarasota Bay, a narrow bay with three inlets direct to the beach, had a devastating complete kill. Beaches and residential canals were littered with tons of rotting fish, and spending a day on the beach became impossible–many beachfront hotels all but shuttered their doors as thousands canceled vacations.

Rotting fish not only wiped out anglers’ hopes but also decimated the beachfront resort business during the extended red tide. (Photo credit FWC)

The red tide finally dissipated as mysteriously as it came, in February this year. The state still has no cure and perhaps never will, though the new conservation-oriented Republican governor Ron DeSantis has appointed a commission and created a department to attack the problem along with blue green algae, a separate issue mostly affecting fresh water but also a major issue in the Indian River Lagoon near Jensen Beach in recent years. (Why there are not more Republican’s tapping into the conservationist/boater/angler/outdoorsman vote these days is a mystery well worth exploring.)

The closure will extend from the Pasco-Hernando county line near Tarpon Springs south (including all waters of Tampa Bay) through Gordon Pass in Collier County, just south of Naples.

The area traditionally has been the heart of snook country in Florida. Redfish and trout were already down when the red tide struck, some think from overharvest as a result of Florida’s booming population of inshore anglers, guides and kayak fishers. There have also been some water quality issues, particularly on Tampa Bay, where the city of St. Petersburg has had several massive sewage spills in recent years. (In general, though, 40 years of conservation efforts on the bay have brought steady improvement in clarity and consequently in the amount of sea grass, a mark of a healthy estuary–until the disastrous red tide struck.)

There’s no question that a complete shutdown will go a long way towards rapidly restoring these important fisheries–the extended snook closure of 2010 to 2013 produced the best snook fishing seen in decades immediately after, and the effect is still obvious, with anglers outside the red tide zones routinely catching and releasing 40 to 50 linesiders in a day when fishing with live sardines.

FWC has been working with partners including Coastal Conservation Association Florida, Duke Energy and Mote Marine Laboratory & Aquarium to raise and release red drum and snook into southwest Florida waters to help address red tide impacts–a popular move with anglers.

Restocking of juvenile fish may help kick start some areas, but research indicates the best solution for recovery is a healthy stock of natural spawners. (Photo credit FWC)

However, past efforts with limited stockings have shown very small returns relative to the cost–most released fingerlings wind up as chum for larger fish. Nature functioning the way it should is the best cure, by far, and shutting down the harvest to allow spawners to survive is the quickest way to recovery.

For those who enjoy eating fresh fish they’ve caught themselves, there are still plenty of targets; flounder and pompano from spring through fall, sheepshead and mangrove snapper–two of the best tasting fish in the sea–in cooler months. Off the beaches, there are Spanish and kings, and on the reefs adult mangrove snapper, yellowtail snapper, red and black grouper and of course red snapper, which seem to be doing exceptionally well these days as a result of very tight management for several years.

It’s going to be a trying year for many who depend on the inshore fishery for their livelihood. Though many guides have already gone to very limited harvest just to protect their own turf, a complete shutdown will surely cause some customers who would have chartered them to choose something else to do during their Florida visit, or perhaps to head to northwest Florida for a charter, where the fisheries remain open.

The good news is that barring another visit from Karenia brevis and related nasties, anglers are likely to see some exciting fishing when the closure comes to an end next year, and hopefully a strong year class of spawning fish may mean even better fishing ahead.

The Surprising Story of Swordfish

The Surprising Story of Swordfish You May Not Know
From NOAA Fisheries
from The Fishing Wire

Today’s North Atlantic swordfish stock is fully rebuilt and maintaining above-target population levels. But there’s work to be done to ensure management measures better support the fishing industry.

Today’s North Atlantic swordfish population is a great fishery rebuilding story.

Twenty years ago, this predatory fish was in trouble. Their population had dropped to 65 percent of the target level. This means there weren’t enough North Atlantic swordfish in the water to maintain their population in the face of fishing by the many countries who share the resource.

Fast forward to 2009 and the international commission that manages species like swordfish declared the Northern Atlantic stock fully rebuilt. That announcement came a year ahead of the 2010 target date set in the International Commission for the Conservation of Atlantic Tuna’s (ICCAT) 10-year rebuilding plan.

“If it’s U.S.-harvested swordfish, consumers can feel confident it’s a smart seafood choice,” said Rick Pearson, NOAA Fisheries fishery management specialist. “We should reward our sustainable stewardship practices at the seafood counter.”


Rebuilding an Important Population

Efforts to restore a dwindling population of North Atlantic swordfish date back to 1985 when NOAA Fisheries implemented the first U.S. Atlantic Swordfish Fishery Management Plan. This plan reduced the harvest of small swordfish, set permitting and monitoring requirements, and launched scientific research on the swordfish stock. Minimum size limits and enforcement processes came shortly after when ICCAT issued its first recommendation on swordfish in 1990.

Despite these and other management strategies implemented over the next eight years, the stock continued to suffer. By the late 1990s, the average weight of swordfish caught in U.S. waters had fallen to 90 pounds, a drop from the 250-pound average fishermen enjoyed in the 1960s. This was in part because the population decline meant fishermen were catching younger fish.

What ultimately reversed their downward course was the broad suite of actions built up by the beginning of the 21st century.

“There is no one measure that could have brought this population back from the decline,” said Pearson. “Sustainable fishery management requires a comprehensive science-based approach that considers the biological needs of the fish population, the health of fisheries, the fishing industry, and coastal communities.”

In the United States today:

A limited number of vessels can target swordfish commercially with longline gear.

All fishermen must abide by minimum size limits, and many must also abide by retention limits.

Closures prevent pelagic longline fishing in waters with historically high levels of bycatch species, including undersized swordfish.

Satellite tracking systems are mandatory on some vessels that target swordfish.

The use of circle hooks is required in commercial fisheries to increase the survival of sea turtles and other animals caught accidentally.

Commercial fishermen must attend workshops where they learn to properly handle and release bycatch, including undersized swordfish.

Observer programs provide fishery scientists and managers with needed data.

Some of these measures can be traced back to the ICCAT rebuilding plan, but many are the result of U.S.-led efforts to protect swordfish, reduce bycatch of other species, and sustainably manage fisheries that interact with swordfish.

Pearson and others also point to the key role the U.S. commercial fishing industry played in helping to establish these domestic efforts and supporting greater international collaboration.

“The United States led the charge internationally to adopt measures to recover North Atlantic swordfish,” said Christopher Rogers, director of International Fisheries. “We pressed our international partners to adopt measures U.S. fishermen were already practicing, such as catch limits, minimum sizes, recording and reducing dead discards, and appropriate observer coverage. Strong U.S. leadership helped ensure the international community shared the burden for rebuilding this iconic species.”

Support for a Valuable U.S. Fishery
In the decade since ICCAT first declared that North Atlantic swordfish are not being overfished, the United States has seen a fall in its total annual catch. In 2017, U.S. fishermen caught just 14 percent of the total swordfish catch reported to ICCAT.

There are several reasons for this decline, says Pearson, including rising fuel prices, an aging commercial fleet, and competition from often lower-quality imported frozen products.

To help more U.S. fishermen take advantage of our national ICCAT-allotted quota, NOAA Fisheries has made several changes in the last decade to commercial and recreational restrictions, such as:

Removing vessel size and horsepower restrictions on pelagic longline permits.

Increasing retention limits on some permits.

Launching a hand gear permit, allowing fishermen to participate in the fishery without spending more to buy a longline permit from another vessel.

Making it easier for fishermen to get and renew permits.

But there is more work to be done to ensure our regulatory program is effective in both maintaining swordfish populations and supporting the fishing industry. We are currently examiningwhether some area-based and gear management measures that affect swordfish fisheries could be modified in light of the success of a program that has reduced bluefin tuna bycatch.

“The U.S. fishery management process is a dynamic process,” said Pearson. “Protecting the North Atlantic swordfish population from overfishing while ensuring fishing opportunities for our recreational and commercial fishermen requires the best available science and responsive management.”

Mysteries of Pacific Salmon Survival

International Voyage Aims to Unravel Mysteries of Pacific Salmon Survival

Pacific Salmon Survival

An international team of biologists is setting out into some of the roughest waters in the North Pacific Ocean in the middle of winter to try to solve the fundamental mystery of Pacific salmon: What determines whether they live or die?

Pursuing Answers in the Remote Ocean

Perhaps the most critical, but least known, part of the salmon life cycle is the few years the fish spend on the high seas, gaining energy to return to their home rivers and spawn. This is where most of the salmon that stream out of Northwest and Alaska rivers each year disappear, most never to be seen again. Now the science team is headed into the remote Gulf of Alaska to try to find out which fish survive, and why.

“What we most need to know about salmon, we mostly don’t know,” said Richard “Dick” Beamish, a longtime salmon researcher in Canada who, with Russian colleagues, launched plans for the research expedition as a centerpiece of the International Year of the Salmon in 2019. He also raised about $1 million to fund the voyage. NOAA Fisheries contributed as well.

“Nothing like this has ever been done before to my knowledge, and I’ve been doing this for 50 years,” Beamish said. “I believe that we will make discoveries that will change the way we think of salmon and do salmon research.”

International Scientists Join Voyage

NOAA Fisheries has three scientists on board the survey, which includes top salmon researchers from Russia, Korea, Japan, and Canada. Scientists believe that Pacific Rim salmon, whether from Alaska, the west coast of the United States, or the east coast of Asia, all spend time in the Gulf of Alaska during their years at sea.

Fisheries biologist Laurie Weitkamp, who is based at the Northwest Fisheries Science Center’s Newport (Ore.) Research Station, will be the chief U.S. scientist for the trip. Weitkamp’s previous research has mainly focused on estuaries and coastal areas, she said, while the open ocean has largely remained a “black box” to scientists searching for better tools to predict salmon returns to west coast and Alaska rivers.

“This is not a place that is very easy to go and do science, especially in winter,” said Weitkamp, who recognizes she will likely get seasick in waves known to tower 50 feet or higher, but is O.K. with that. “To understand what is affecting these fish, you have to go where the fish are, and now we are finally about to do that.”

Fisheries biologists Charlie Waters and Gerard Foley from the Alaska Fisheries Science Center will be collecting samples for several studies to learn more about salmon condition and diet. In particular, they want to learn more about what pink salmon are eating and whether they are in competition with sockeye, Chinook, and coho for prey resources. All of these salmon species support important commercial, recreational, and subsistence fisheries in Alaska.

“We have a vested interest in knowing what’s going on during the winter months,” said Foley. “It is a critical, critical time in the life history of these fish.”

The science team will set out in mid-February 2019 from Vancouver, B.C., on a Russian research ship named Professor Kaganovskiy, backed by funding from the Canadian government, the Pacific Salmon Commission, the British Columbia Salmon Farmers Association, and others. The ship will spend a month crisscrossing the Gulf of Alaska with trawl nets and examining the salmon they catch with tools that range from microscopes to DNA fingerprinting.

Salmon’s Race for Survival

Scientists have long suspected that the fate of salmon migrating into the ocean is sealed during their first year at sea. The fish that grow large enough, fast enough to elude predators and make it through the first winter are the fish that will return to rivers to spawn–and to be caught in fishing nets. For the first time, the scientists aboard Professor Kaganovskiy will be able to test that theory, using clues like the tiny bones in the ears of fish, known as otoliths, that reflect each fish’s growth.

Roughly 99 of every 100 salmon that leave rivers for the ocean never return. The team wants to know what distinguishes those fish from the rare salmon that make it back alive.

“This is the time of year when we think most of the mortality is occurring, so this is when we want to be there to understand the fundamental mechanisms that regulate the production of salmon,” Beamish said. The better they understand the most influential factor affecting fish, he said, the closer they will be to providing more accurate forecasts of salmon returns to west coast rivers.

That, in turn, will help fisheries managers, fishermen, and others effectively manage salmon in a changing ecosystem, Beamish said.

Researchers also believe that different salmon stocks, such as those from rivers including the Snake and Columbia, migrate through certain parts of the Gulf of Alaska, capitalizing on the food available in different areas. The carrying capacity of those areas will also help determine how many fish return to the rivers.

“We’ve never been able to test that before,” Beamish said. “Now we have a chance to be there and see it happening in real time.”

Florida’s Saltwater Fisheries Boundaries

How Florida’s Saltwater Fisheries Boundaries Came to Be

Florida’s Saltwater Fisheries Boundaries


When you are on a boat, it’s hard to imagine boundaries. The sea is the sea. Wave after wave, it all looks the same. Above-water landmarks are few and far between. There are no signs that say, “now entering federal waters.”

Regulatory boundaries are sometimes hard to fathom. In Florida, one of the biggest fishery management boundaries is that between state waters, where the Florida Fish and Wildlife Conservation Commission (FWC) makes the regulations, and federal waters, which are mostly managed by federal fishery councils and NOAA Fisheries with input from FWC. Sometimes regulations are the same in both state and federal waters, but not always, which is why it is important to know there is a line, and where that line is.

Florida is the only state where that boundary shifts depending on which coast you are on. State waters in the Atlantic extend out to 3 nautical miles, while in the Gulf they extend out to 9 nautical miles. But why, as many people ask? How did this come to be?

State boundaries in open waters of the United States first began to be defined in the 1940s, mainly due to concerns about rights for oil beneath submerged lands.

In a 1947 case, the U.S. Supreme Court ruled against California saying the federal government possessed rights in all submerged lands of the Pacific seaward of the low-water mark. The U.S. Supreme Court ruled similarly against Louisiana and Texas.

Congress reacted by creating the Submerged Lands Act of 1953.

This act declared that states owned the submerged lands, and the natural resources within, out to three geographic miles. The act included a provision that a state’s boundary could be extended if it was beyond three geographic miles from the coast prior to when statehood was achieved.

Florida immediately asserted their boundary went beyond 3 geographic miles before it achieved statehood in 1845 and that Congress approved its boundary when Florida was readmitted into the Union after the Civil War. The claim did not make it to the Supreme Court until 1960, where it was proven that Article I of Florida’s Constitution (1868), which was approved by Congress, described the boundary off Florida’s Gulf Coast as “three leagues from mainland.”

Florida’s Atlantic coast boundary was settled at 3 geographic miles from shore.

One nautical league is equal to 3 nautical miles, therefore the “three leagues from mainland” is equal to the 9 nautical miles we manage in the Gulf today. For fishery management purposes, federal waters extend from where state waters end out to about 200 nautical miles (less so in areas where our waters butt up against other country’s waters such as in the Caribbean). Federal waters are also known as the Exclusive Economic Zone or EEZ. For more on the history of this nation’s boundaries, visit NauticalCharts.NOAA.gov/data/us-maritime-limits-and-boundaries.html.

For those interested in measurements, while we use nautical miles today, you may have noted that the original language used geographic miles. There’s really not much of a difference between the two. A geographic mile ( 1 minute of arc along the Earth’s equator) is slightly longer than a nautical mile (a geographic mile is 6,087.08 feet and a nautical mile is 6.076.11549 feet), but the difference between 9 geographic miles and 9 nautical miles is less than 100 feet. (Note a geographic mile is also different than a standard English mile, 5,280 feet.)

Another interesting tidbit comes from the creation of the 3-mile limit itself, which sources say stems from how far a cannon ball could reach when fired from land. It is also said that, due to the earth’s curvature, 3 nautical miles is how far it is to the horizon.(Of course, this depends on how high your eyes are above the water.)

For fisheries management, we’ve created many additional boundaries throughout the years. We have species-specific management zones for fish such as red drum, and FWC manages some species in both state and federal waters. We take into account many different aspects when creating these boundaries, including differences in fish populations, fishing practices and stakeholder needs.

There may not be signage, but it’s always important to know where you are. State/federal boundary lines are marked as the natural resource line on NOAA nautical charts and these lines are also preloaded on most marine GPS units.
