MIKE SPINNEY: The gradual and sudden decline of striped bass

May 19, 2021 — Striped bass, also known as rockfish, are arguably the most economically important finfish on the Atlantic seaboard. According to a 2005 economic study by Southwick Associates, commercial and recreational fishing for stripers generated more than $6.8 billion in total economic activity, supporting more than 68,000 jobs. At the time, striped bass were abundant in the Chesapeake Bay and throughout their migratory range, from North Carolina to Maine.

Twenty years earlier, striped bass were practically nonexistent. Scooped up in commercial nets and plucked by rod and reel by a growing number of recreational anglers throughout the 1970s, stripers had been fished to the brink of oblivion when a moratorium was enacted in 1985. Remarkably, once left alone to reproduce in the Chesapeake and Delaware bays, as well as the Hudson River, the fish were spawning in record numbers. In 1995, five years after the moratorium was lifted, the species was declared “fully recovered” by the Atlantic States Marine Fisheries Commission, the interstate body tasked with managing them.

The rebound was touted as a success. Rockfish became a symbol of the ASMFC’s fisheries management prowess. But almost as soon as the commission resumed the task of allotting states their portion of the striped bass pie, things started to go downhill until, in 2019, the commission declared striped bass overfished.

Omega trims Atlantic steamer fleet with conversion; pound-net skiff gets overhaul at Virginia railway

May 3, 2021 — With the help of Ampro Shipyard in Weems, Va., Omega Protein in Reedville is busy getting its menhaden fishing fleet ready for Virginia’s 2021 menhaden fishing season. The season opened in May.

Omega recently announced it’s cutting back on its Chesapeake Bay fishing fleet, as six boats will be fishing this season. Last year, the firm had seven menhaden steamers working Chesapeake Bay and the Atlantic Ocean.

The Tideland, one of the largest and oldest vessels in the fleet, will leave the fishing end of the business. It will remain in the fleet, however, as a carry-away boat. The 218-foot Tideland was launched in 1966. “She has caught a jag of fish in her lifetime,” said Omega’s Reedville Vessels Manager Harvey Hamm.

Tideland will require only a minor conversion to switch from fishing boat to carry-away boat. It will require installation of new pumps, modification of the hydraulic system and some new stainless steel piping.

The work will be done with the boat in-water at the Omega Reedville plant by way of a partnership between the Ampro work force and Omega’s boat maintenance crew. “We rely on Ampro to do a lot of our work,” said Hamm. “When we have a need we can count on them coming to our place to jump in and take care of the problem.”

Using Science to Support the Chesapeake Bay’s Rockfish Population

April 29, 2021 — The following was released by NOAA Fisheries:

Heading out on the Chesapeake Bay for trophy rockfish season is a treasured rite of spring for recreational anglers. In the Chesapeake, fishermen often call striped bass “rockfish” because these fish often hang out near oyster reef “rocks.”

But this year, the spring season will be a bit diminished in the Chesapeake with a later start, and fewer days, that has been the case in the past. Changes implemented by Maryland and Virginia in 2019 will continue in 2021. This is part of a broader effort to help the striped bass population rebound.

Reports from anglers and fishermen and scientific data both indicate that the population is declining. Analyses by the Atlantic States Marine Fisheries Commission show that the striped bass population along the Atlantic Coast is decreasing. Every year, the Maryland Department of Natural Resources reports on the species by tracking an index of juvenile striped bass. The survey was started in 1954. Since then, the average index is 11.5 (arithmetic mean catch per haul); the index in fall 2020 was 2.5. In the last decade, six years have been below average. That means there are fewer fish to grow into the spawning stock.

Maryland Rockfish Limits Set, Including July Closure

March 30, 2021 — After proposals and public comment, we now know what rockfish limits will look like in Maryland this season.

The Maryland Department of Natural Resources (DNR) issued striped bass harvest regulations for recreational anglers and charter boat clients for the summer and fall fishery, May 16–Dec. 10, 2021. This year will be a split season, closing Maryland waters to all striper fishing July 16–31. No private anglers or charter boat guests and crews may target striped bass, even catch-and-release, during those two weeks.

DNR designed this seasonal closure to avoid the period when water quality and high temperatures are most stressful and harmful to striped bass in the upper Bay, according to DNR’s own data. Virginia and D.C. also have seasonal closures: Virginia closes its striped bass season for the lower Chesapeake from June 15 to October 4, while the Potomac River is closed to all targeting of striped bass fishing from July 7 through August 20.

Outside of the Maryland summer closure period, private recreational anglers may keep one striped bass per day, with a minimum size of 19 inches. Charter boat clients may keep two stripers per day, with a minimum size of 19 inches, provided the boat’s captain participates in DNR’s daily electronic reporting system. During any chartered fishing trip, neither the captain nor mate may land or possess rockfish for personal consumption.

NOAA Chesapeake Bay Office Announces Fisheries Research Funding Opportunity

March 8, 2021 — The following was released by NOAA Fisheries:

Up to $250,000 in total fiscal year 2021 grant funds is available to support research into how key Chesapeake Bay fisheries species change their behavior to deal with changing habitat and climate. The NOAA Chesapeake Bay Office’s Fisheries Research Program invites applications through April 26, 2021.

Climate change is already affecting the Chesapeake Bay—and the wildlife that lives there. Between 1901 and 2017, the average air temperature in the Chesapeake Bay watershed rose (depending on location in the watershed) between 0.4 and 2.5 degrees F. Increases in water temperature can affect fish spawning areas and migratory patterns. We also expect a shift to more frequent high-precipitation storms, which will affect salinity levels. That in turn will affect fish species distribution and diversity.

We want to better understand how key Chesapeake Bay fisheries species will be affected as conditions change. Resource managers can include that science in their decision-making process. Projects funded through this grant will help us gain that knowledge.

The grants will also provide funding to improve social science around fisheries and habitat. We hope to quantify the role of nearshore habitat for local communities and fisheries in the Middle Peninsula area of Virginia. There are many habitat conservation and shoreline restoration efforts under way there.

We want to help develop the next generation of scientists in NOAA’s mission areas. We are interested in supporting research projects that employ and educate undergraduate or graduate students from groups underrepresented in marine science careers, including minorities.

The deadline for application is April 26, 2021. We invite potential applicants to learn more about the application process by joining us for a webinar on February 26 at 1 p.m. EST.

REPORT: CLIMATE CHANGE A MAJOR THREAT TO RECREATIONAL FISHING

February 24, 2021 — A new report by fly fishing industry leaders brings to light what scientists have long known: that fishing is suffering from the effects of climate change—and offers solutions.

The American Fly Fishing Trade Association and its nonprofit AFFTA Fisheries Fund released the report last week, which acknowledges, “Climate change is significantly affecting ocean ecosystems, the abundance and distribution of fish, and the nature of saltwater fishing.”

AFFTA sees the effects of climate change and overfishing as principal threats to fisheries that the fly-fishing industry has long fought to address. This blue-ribbon report offers a systematic approach to strengthen marine fisheries conservation and management, support recreational fisheries, and lead to more abundant marine fisheries in all U.S. ocean waters.

Though the report looks at these issues on a national scale, it offers many recommendations that apply to the Chesapeake Bay and its tributaries, from warming of upland coldwater brook trout streams to effects on oyster shells and loss of shoreline habitats. One particularly applicable example is the report’s commitment to work with coastal states to increase the size and distribution of seagrass beds, by improving water quality and planting grasses. It notes that coastal ecosystems like marshes and grassbeds are capable of absorbing carbon at rates up to four times those of forests on land.

Rock-bottom rockfish numbers drag down Chesapeake Bay health score: Report

January 5, 2021 — Despite progress on pollution and habitats, the Chesapeake Bay has received another low health grade from the nonprofit Chesapeake Bay Foundation, this time due to issues with fisheries.

Results of the bi-annual State of the Bay report released Tuesday say the bay’s health scored a D+ in 2020.

Though most water quality measurements are showing improvement, the bay’s overall score was sunk by abysmal ratings on critical fisheries, including rockfish, oysters and shad.

Rockfish scored a 49 out of 100 on CBF’s scale, which on its own qualifies as a C+ grade. But that score represents a decrease of 17 points since 2018, the largest decline in any single indicator CBF has recorded in over a decade, said Chris Moore, senior regional ecosystem scientist with CBF.

KRISTEN MINOGUE: Shark tags reveal an endangered species returning to natural refuge

December 28, 2020 — In the coastal waters of the mid-Atlantic, an endangered shark is making a comeback. Led by former Smithsonian postdoc Chuck Bangley, scientists at the Smithsonian Environmental Research Center (SERC) tagged and tracked nearly two dozen dusky sharks over the course of a year as part of the Smithsonian’s Movement of Life Initiative. They discovered that a protected zone put in place 15 years ago is paying off — but with climate change, it may need some tweaking.

Dusky sharks are what Bangley calls “the archetypal big, gray shark.” Born 3 feet long, as babies, they’re already big enough to prey on some other shark species. But they’re slow-growing. It can take 16 to 29 years for them to mature. If their populations take a hit, recovery can take decades.

An endangered species, duskies aren’t very common in Delaware waters. When they do surface, they’re easily mistaken for sandbar sharks. But in this new study, the Smithsonian tracked dusky sharks swimming past the southern tip of Delaware on their migrations up and down the Atlantic. For conservationists, it’s a sign that protections put in place are slowly starting to pay off.

The sharks’ numbers plummeted in the 1980s and 1990s, when well-intentioned managers offered sharks as an “alternative fishery,” while other stocks, like cod, were collapsing. The overfishing that followed wiped out anywhere from 65% to 90% of the Chesapeake’s duskies, said Bangley, now a postdoc at Dalhousie University in Nova Scotia. Managers banned all intentional dusky shark fishing in 2000. Five years later, they created the Mid-Atlantic Shark Closed Area along the North Carolina coast. The zone prohibits bottom longline fishing, which can ensnare dusky sharks, for seven months of the year.
