Regional Regulators Vote For 3-Year Closure Of Maine Shrimp Fishery

November 19, 2018 — A panel of regulators from Maine, New Hampshire and Massachusetts voted Friday to put a three-year moratorium on the commercial fishery for Northern Shrimp, also known as Maine shrimp. Maine’s representatives at the meeting in Portland wanted some type of season preserved, but they were outnumbered.

The decision came after Katie Drew, a scientist with the Atlantic States Marine Fisheries Commission, told the panel there was virtually no chance the shrimp would bounce back from depleted levels before 2022 and, in fact, might never recover. Above all, she says, the Gulf of Maine, has warmed to the limits of the shrimp’s reproductive capacity.

“The warmer the waters the less baby shrimp you have the next year,” says Drew. “And so we’ve had a lot of warm waters, and we’re just not getting a enough baby shrimp into the population. And in addition a lot of things like to eat northern shrimp.”

Predators such as red hake, spiny dogfish and squid, which are growing more abundant in some parts of the Gulf. The pressure they are putting on shrimp is a growing problem, even though one top predator, humans, haven’t been in the picture since 2014.

Historically, the commercial shrimp fishery, which traditionally started in December, has been dominated by boats from Maine. But it’s been closed for four consecutive years.

Panel member Mike Armstrong, assistant director in the Massachusetts Division of Marine Fisheries, says the regulators should bow to reality and proposed the three-year closure.

ASMFC: Data Workshops Scheduled for Atlantic Menhaden Single-Species & Ecological-Based Benchmark Stock Assessments

February 28, 2018 — ARLINGTON, Va. — The following was released by the Atlantic States Marine Fisheries Commission:

The Atlantic States Marine Fisheries Commission has begun work on two Atlantic menhaden-specific benchmark assessments: a single-species benchmark assessment and an ecological-based benchmark assessment. The assessments will be used to evaluate the health of the stock and inform the management of the species in an ecological context. The assessments will be peer-reviewed at the end of 2019.

A Data Workshop for both assessments will be conducted the week of April 23rd; details on the location will be released once they become available. The Atlantic Menhaden Technical Committee and Stock Assessment Subcommittee will meet April 23-25 to discuss the single-species assessment and the Ecological Reference Point Workgroup will meet April 25-27 to discuss the ecological-based assessment.

A second Data and Modeling Workshop will be held in September; information on the dates and location will be provided once they are finalized. All Data and Modeling Workshops are open to the public, with the exception of discussions of confidential data, when the public will be asked to leave the room.

The Commission welcomes the submission of data sources and alternate models that will improve the accuracy of the assessments. This includes, but is not limited to, data on commercial landings and discards, catch per unit effort, biological samples (length or age frequency), and life history information (growth, maturity, fecundity, natural mortality, spawning stock biomass). For the ecological-based assessment, the Commission is also interested in predation information on Atlantic menhaden (i.e., predator diets, consumption rates) and predator stock size information (i.e., Atlantic striped bass, weakfish, bluefish and spiny dogfish). For data sets to be considered, the data must be sent in the required format with accompanying description of methods to Dr. Kristen Anstead, Stock Assessment Scientist, at kanstead@asmfc.org by Friday, April 6, 2018.

For alternate models to be considered, the model description, model input, and complete source code must be provided to Dr. Katie Drew, Stock Assessment Team Leader, at kdrew@asmfc.org by the model deadline. For alternate multispecies or ecosystem models, the deadline is Friday, June 1, 2018. For alternate single species models, the deadline is Thursday,November 1, 2018. Any models submitted without complete, editable source code and input files will not be considered.

Menhaden catch limit raised along Atlantic coast, slashed in Bay

November 20, 2017 — East Coast fishery managers plan to increase the coastwide menhaden catch by 8 percent next year, while slashing the amount that can be harvested from the Chesapeake Bay.

But despite heavy pressure from environmental groups, the Atlantic States Marine Fisheries Commission balked at a proposal that would have required fishery managers to take into account the ecological role of the small, oily fish when setting future harvest levels.

By the end of their two-day meeting in mid-November, commissioners had succeeded in disappointing and pleasing environmentalists and industry officials alike — typically not at the same time — while setting up another big debate two years from now over how to account for the role menhaden play as a food source for other species.

In a statement after the meeting, Robert Ballou, of the Rhode Island Department of Environmental Management and chair of the ASMFC Menhaden Board, acknowledged that many people were left disappointed by the decisions that will guide harvests for the next two years. But he said the commission’s actions demonstrated a “commitment to manage the menhaden resource in a way that balances menhaden’s ecological role with the needs of its stakeholders.”

It was the latest round in a decades-long struggle over how to manage the catch of Atlantic menhaden, a fish almost never eaten by humans that is an important food for a host of marine species. By weight, menhaden make up the largest catch in both the Chesapeake and along the East Coast, but by nearly all accounts their abundance is increasing, especially in New England. In fact, the ASMFC’s science advisers indicated that the current coastal catch limit of 200,000 metric tons could be increased by more than 50 percent with little chance of overfishing the species.

But conservation groups have long argued that such assessments do not fully account for the importance of menhaden as a food source for marine mammals, many birds, and a host of other fish, such as striped bass.

It is part of a larger, long-running debate between conservation groups and the fishing industry over how to treat forage fish, which include menhaden, anchovies and other small species that provide a critical link in the aquatic food chain by converting plankton into nourishment for larger predators.

Historically, conservationists contend that forage species have received less attention — and protection from overfishing — than the larger predators, such as striped bass. Prior to the meeting near Baltimore, conservationists had gathered a record-setting 157,599 comments urging the ASMFC to adopt new harvest guidelines, or reference points, that would take the ecological role of the fish into account when setting catch limits. If adopted, the guidelines would almost certainly have required a reduction in the current coastwide menhaden catch.

But critics — which included ASMFC’s own scientific advisers, as well as the commercial menhaden industry — said the reference points under consideration were based on studies of other species in other places and may not be applicable to menhaden.

Ultimately, the commission — a panel of state fishery managers that regulates catches of migratory fish along the coast — voted 13–5 to delay the adoption of ecological reference points until a panel of scientists it has assembled can make its own ecological recommendations, tailored specifically to menhaden. Those recommendations are not expected to be ready until 2019.

Dozens of activists attended the meeting, many holding bright yellow signs that said, “Little Fish Big Deal,” “Keep it Forage” or “Conserve Menhaden.” Many were surprised not only to be defeated after the huge volume of comments — more than 99 percent in favor of ecological reference points — but also by the lopsided vote.

Atlantic Sturgeon Benchmark Stock Assessment Indicates Slow Recovery Since Moratorium; Resource Remains Depleted

October 19, 2017 — NORFOLK, Va. — The following was released by the Atlantic States Marine Fisheries Commission:

The Atlantic States Marine Fisheries Commission’s Atlantic Sturgeon Management Board reviewed the results of the 2017 Atlantic Sturgeon Benchmark Stock Assessment, which indicate the population remains depleted coastwide and at the distinct population segment (DPS) level relative to historic abundance. However, on a coastwide basis, the population appears to be recovering slowly since implementation of a complete moratorium in 1998. Despite the fishing moratorium, the population still experiences mortality from several sources but the assessment indicates that total mortality is sustainable. The “depleted” determination was used instead of “overfished” because of the many factors that contribute to the low abundance of Atlantic sturgeon, including directed and incidental fishing, habitat loss, ship strikes, and climate changes.

Atlantic sturgeon are a long lived, slow to mature, anadromous species that spend the majority of their life at sea and return to natal streams to spawn. While at sea, extensive mixing is known to occur in both ocean and inland regions. The Commission manages Atlantic sturgeon as a single stock, however, NOAA Fisheries identified five DPSs of Atlantic sturgeon based on genetic analysis as part of a 2012 Endangered Species Act listing: Gulf of Maine, New York Bight, Chesapeake Bay, Carolina, and South Atlantic. Accordingly, this benchmark assessment evaluated Atlantic sturgeon on a coastwide level as well as a DPS-level when possible.

Atlantic sturgeon are not well monitored by existing fishery-independent data collection and bycatch observer programs, and landings information does not exist after 1998 due to implementation of a coastwide moratorium. Because of this, Atlantic sturgeon are considered a “data-poor” species which hindered the Stock Assessment Subcommittee’s ability to use complex statistical stock assessment models, particularly at the DPS-level. Based on the models used, the stock assessment indicated the Atlantic sturgeon population remains depleted relative to historic levels at the coastwide and DPS levels. Since the moratorium, the probability that Atlantic sturgeon abundance has increased coastwide is high and total morality experienced by the population is low. The results are more mixed at the DPS-level due to sample size and limited data, but the Gulf of Maine and Carolina DPS appear to be experiencing the highest mortality and abundance in the Gulf of Maine and Chesapeake Bay DPS is not as likely to be at a higher level since the moratorium.

The Board approved the 2017 Atlantic Sturgeon Benchmark Stock Assessment and Peer Review Reports for management use and discussed the need to support management actions that have contributed to recovery seen to date (e.g., the moratorium, habitat restoration/protection, better bycatch monitoring) and continue to work on improving them (e.g., identifying bycatch and ship strike hotspots and ways to reduce those interactions). It is important to note there has been a tremendous amount of new information about Atlantic sturgeon collected in recent years. Although this does not resolve the issue of the lack of historical data, it certainly puts stock assessment scientists and fisheries managers on a better path going forward to continue to monitor stocks of Atlantic sturgeon and work towards its restoration.

Atlantic sturgeon are managed through Amendment 1 and Addenda I-IV to the Interstate Fishery Management Plan (FMP) for Atlantic Sturgeon. The primary goal of the amendment is to achieve stock recovery via implementation of a coastwide moratorium on Atlantic sturgeon harvest and by prohibiting the possession of Atlantic sturgeon and any parts thereof. The moratorium is to remain in effect until 20-year classes of spawning females is realized and the FMP is modified to reopen Atlantic sturgeon fisheries.

The Atlantic Sturgeon Benchmark Stock Assessment, as well as the Stock Assessment Overview (which is intended to aid media and interested stakeholders in better understanding the Commission’s stock assessment results and process), will be available the week of October 23rd on the Commission website, www.asmfc.org, on the Atlantic Sturgeon webpage under stock assessment reports. For more information on the stock assessment, please contact Dr. Katie Drew, Senior Stock Assessment Scientist, at kdrew@asmfc.org and for more information on management, please contact Max Appelman, Fishery Management Coordinator, at mappelman@asmfc.org or 703.842.0740.
