Science Center for Marine Fisheries Releases Evaluation and Summary of Latest Atlantic Menhaden Assessments

February 4, 2020 — The following was released by the Science Center for Marine Fisheries:

Dr. Steve Cadrin, Professor at the School for Marine Science and Technology at the University of Massachusetts Dartmouth and past President of the American Institute of Fishery Research Biologists, has completed an evaluation and summary of the latest Southeast Data, Assessment, and Review (SEDAR) Atlantic menhaden stock assessments.  Dr. Cadrin’s evaluation and summary was commissioned by the Science Center for Marine Fisheries (SCeMFiS).  SEDAR completed two assessments in January, a traditional single-species benchmark assessment, and a first-of-its-kind ecological reference point assessment.

Among other conclusions, Dr. Cadrin’s evaluation and summary finds that, according to the peer-reviewed assessments, the menhaden population is healthy, with menhaden fishing mortality remaining low. Atlantic menhaden was certified as sustainable by the Marine Stewardship Council in 2019. When comparing the two assessments, Dr. Cadrin notes that the single-species assessment “is the best scientific information available for fishery management.”

The evaluation and summary of the Atlantic menhaden assessments was one of the 2020 projects recently approved by SCeMFiS, which is part of the National Science Foundation’s Industry-University Cooperative Research Centers program. The review was commissioned to provide a non-technical summary of the two 400+ page Atlantic States Marine Fisheries Commission (ASMFC) menhaden assessments, so that menhaden fishery stakeholders would have, in an easily-comprehensible format, the information needed to support the best path to science-based management of the fishery.

Single-Species Assessment Remains Best, Most Reliable Information Available

Dr. Cadrin evaluated and summarized both the traditional, single-species menhaden stock assessment, as well as the new assessment that includes a multispecies focused analysis of menhaden and species which prey upon menhaden as part of their diet. This effort is a key part of the ASMFC’s efforts to transition to ecosystem-based fisheries management.

“The single-species assessment includes much more information on size and age composition, fishery selectivity, and recruitment variability than the multi-species models that were developed, but all models provide similar perceptions of menhaden stock trends since the 1990s,” writes Dr. Cadrin.

Other notable points by Dr. Cadrin include the improvements that the single-species assessment made in getting more accurate measurements of menhaden natural mortality, and the assessment’s conclusion that menhaden fishing mortality remains low, while the estimate of the current stock size is high.

Lower Menhaden Fishing Would Not Help Overfished Striped Bass

Dr. Cadrin’s evaluation and summary of the ecosystem-based assessment focuses in part on how it modeled the relationship between menhaden and striped bass. Most notably, he observes the assessment finds that, due to current overfishing and the overfished status of striped bass, decreasing the menhaden harvest would have little impact on striped bass stocks.

“At the current rate of fishing mortality on striped bass, there is little change in the long-term expectation for the striped bass stock from fishing menhaden at a lower rate than the single species target. Therefore, there appears to be negligible benefit to bass from fishing menhaden lower than the single species target,” Dr. Cadrin writes.

The assessments are the culmination of a two-year effort to gather and analyze available data for Atlantic menhaden from the fishery-independent sampling programs of the Atlantic states, commercial purse-seine reduction fishery, and commercial bait fishery.  All those who worked on the single-species assessment and the ground-breaking ecosystem assessment – the SEDAR 69 Panel, the Atlantic Menhaden Technical Committee (TC), the Stock Assessment Subcommittee (SAS), the ASMFC Ecosystem Reference Points Work Group, the Center for Independent Experts (CIE), the technical reviewer and the review panel chair — deserve credit for the completion of this task.

Both assessments will be discussed at this week’s ASMFC meeting.

SCeMFiS Announces Funding for Two Research Projects Impacting Fisheries Management

November 27, 2017 — CAPE MAY, N.J. — The following was released by the Science Center for Marine Fisheries:

The Industry Advisory Board (IAB) of the Science Center for Marine Fisheries (SCeMFiS) has allocated $26,467 in funding for two research projects during the Fall IAB Meeting held October 31-November 1, 2017 in Cape May, New Jersey. The awards span the broad mission of the SCeMFiS and include research on marine mammals and continued funding for the omnibus stock assessment proposal for Atlantic herring.

Funded projects are as follows:

  • Independent Advisory Team for Marine Mammal Assessments – Phase V – this team addresses uncertainties in slow growing marine mammal populations and the interactions between marine mammals and fishing operations. PI: Paula Moreno, USM
  • Stock Assessment Team – stock assessment teams provide external support to NMFS for benchmark assessment working groups with a focus in 2018 on the Atlantic herring. PI: Steve Cadrin, UMass Dartmouth

This fall marked a trend to include industry sponsorship of social events and hold meetings close to prospective new members in an effort to attract and showcase research projects. The Cape May oceanfront provided a beautiful venue for the Fall IAB Meeting. Lund’s Fisheries Inc. and Atlantic Capes Fisheries, Inc. graciously provided food, beverages and evening social events on the Cape May Whale Watcher as well as Cold Spring Village/Brewery and The Grange Restaurant.

Jeff Reichle, President of Lund’s Fisheries, Inc. commented, “It was an honor to host the Fall IAB Meeting of SCeMFiS in the port of Cape May. The fishing industry in New Jersey, both commercial and recreational, has a huge impact on our coastal communities and we are very pleased to be part of this science based organization focused on cooperative research with NMFS and other fisheries management bodies to ensure that we have healthy, sustainable fisheries now and in the future.”

MASSACHUSETTS: ‘A new era’: UMass Dartmouth SMAST building to open

September 29, 2017 — NEW BEDFORD, Mass. — UMass Dartmouth’s new marine science building is finished, its laboratories gleaming with the promise of new research.

The $55 million School for Marine Science and Technology building, dubbed SMAST East, officially opens today in the South End of New Bedford. At 64,000 square feet, it nearly triples the physical size of SMAST, a graduate school and research center focusing on fisheries, coastal preservation, ocean modeling, and climate change.

The new building reunites the school’s programs in a campus-like setting. For several years, some have been housed in the AT&T building in Fairhaven for lack of space.

“Just to be back together was great,” said Steve Cadrin, a professor and chairman of the Department of Fisheries Oceanography. But more importantly, it’s a world-class facility, he said.

The building also helps cement the school’s relationship with the state Division of Marine Fisheries. The agency leased the third floor for its New Bedford office, and it will have a first-floor office for permitting.

The Division of Marine Fisheries works hand-in-hand with SMAST on research and sometimes hires its Ph.D. graduates. Recent hires have represented the agency on New England Fisheries Management Council committees, helped the state understand fish surveys, and studied algae blooms.

The agency’s director, David Pierce, is an adjunct professor.

“We are now in a far better position to collaborate,” he said.
