SCEMFIS Research Provides New Insights on Gray Seals; Suggests Alternatives to Current Management

September 28, 2020 — The following was released by the Science Center for Marine Fisheries:

Decades of strict conservation and management have led to a rebound of gray seals in the North Atlantic. Now, research from the Science Center for Marine Fisheries (SCEMFIS) is providing new insights into this population, how local fisheries interact with them, and better options to manage them.

The study, led by Drs. Doug DeMaster, Paula Moreno, Andre Punt, and John Brandon of the Independent Advisory Team for Marine Mammal Assessments, is evaluating how interactions with regional fisheries, specifically the New England sink gillnet and bottom trawl fisheries, affect the gray seal population. Revising estimates for key parameters such as abundance, levels of bycatch, and the proportion of seals crossing between the U.S. and Canada, the study is providing alternative approaches for the National Marine Fisheries Service (NMFS) to estimate Potential Biological Removal (PBR) levels. PBR determines the number of gray seals that can be removed annually by human activities without threatening the conservation status of the stock.

Preliminary results from the study find that calculations made by NMFS to determine the PBR threshold are likely too conservative. Specifically, it finds that NOAA’s estimate of gray seal productivity, a key metric in determining PBR, is too low by approximately 17 percent. It also finds that NOAA is likely being overly conservative in how it classifies at least one fishery, based on productivity, bycatch levels and assumptions regarding transboundary movements of gray seals between the U.S. and Canada.

Under the U.S. Marine Mammal Protection Act (MMPA), bycatch is strictly managed based on PBR levels, and fisheries are often required to adopt burdensome mitigation strategies as a result. Having an accurate estimate of the seal population that is interacting with commercial fisheries, and setting an appropriately precautionary estimate of PBR, is critical not just for seals, but for the fisheries that interact with them.

“With the gray seal population continuing to grow, the fishing industry is increasingly concerned about bycatch and other issues that come from seal interactions,” said Greg DiDomenico, a member of SCEMFIS’ Industry Advisory Board. “The results of this study will provide options for managing gray seals that are both consistent with federal conservation goals and may be helpful in avoiding unnecessarily burdensome regulations on fishermen.”

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.”

The Industry Advisory Board of the Science Center for Marine Fisheries (SCeMFiS), supported by the National Science Foundation I/UCRC Program, provides research related to major challenges in fisheries management and brings participants from industry, government, and other organizations in need of science-based solutions into contact with academic scientists capable of providing that expertise.

The SCeMFiS Industry Advisory Board is composed of members from the shellfish and commercial finfish industries and the NMFS-Northeast Fisheries Science Center. The organizational structure provided by the Center permits members to control the science agenda in exchange for financial support under the sponsorship of the NSF.
