Study finds existing forage fish management is working

July 9, 2021 — Efforts to ratchet down fishing effort on species like herring and menhaden in the name of “extra precautionary management” in most cases are unlikely to bring additional benefits for stocks of predator species that eat them, according to a new study.

“Our results indicate that predator productivity was rarely influenced by the abundance of their forage fish prey,” wrote authors Christopher Free of the University of California-Santa Barbara, Olaf Jensen of the University of Wisconsin-Madison, Ray Hilborn of the University of Washington. “Only 6 predator populations (13 percent of the total) were positively influenced by increasing prey abundance and the model exhibited high power to detect prey influences when they existed,” according to their paper titled “Evaluating impacts of forage fish abundance on marine predators,” originally published in the journal Conservation Biology.

“These results suggest that additional limitation of forage fish harvest to levels well below sustainable yields would rarely result in detectable increases in marine predator populations.”

The findings were released July 6 through the Science Center for Marine Fisheries, a cooperative effort to improve sustainability of fisheries and reduce uncertainty in biomass estimates with work by university partners led with the University of Southern Mississippi Virginia Institute of Marine Science, College of William and Mary, as academic sites.

“Our work suggests that the sustainable limits that we already employ are sufficient for maintaining forage fish abundance above the thresholds that are necessary for their predators,” Free of UC Santa Barbara in a statement describing the findings. “Predators are highly mobile, they have high diet flexibility, and they can go and look for forage fish in places where they’re doing well, switch species for species that are doing well, and have often evolved to breed in places where there’s high and stable forage fish abundance.”

New Study Finds Strong Currents Off Nantucket Prevent Development of Stable, Biologically Diverse Benthic Communities

February 22, 2021 — The following was released by the Science Center for Marine Fisheries (SCEMFIS):

Complex ocean environments, full of features such as cobble, rocks, and boulders, are usually home to a diversity of marine life; as a result, fisheries managers have often sought to preserve these areas from outside interference. But one such area off the coast of Nantucket may be a significant exception to this rule, according to a new study from the Science Center for Marine Fisheries (SCEMFIS).

The study, from Eric Powell, Jeremy Timbs, and Kelsey Kuykendall of the University of Southern Mississippi and Roger Mann and M. Chase Long of the Virginia Institute of Marine Science, analyzes survey data from the Nantucket Shoals area of the Great South Channel in the Atlantic, an area of considerable substrate complexity and home to the Great South Channel Habitat Management Area (HMA). But the study found that, due to the area’s strong currents and seafloor activity, much of the faunal diversity expected from substate complexity has failed to develop.

Specifically, the study found few examples of the kind of charismatic marine life—such as tunicates, sponges and anemones—that usually attach themselves to prominent features like boulders and rocks in habitats where they occur. The study attributes this to the high-energy currents that frequently run through the area, as well as the sand on the seafloor regularly scouring the rocks as a result of the currents. The absence of mussels attached to hard bottom features, and the presence of barnacle scars where barnacles have been eroded off the rocks, show clear evidence of the rigor of the benthic environment that minimizes the use of these substrates by attached bottom creatures.

According to the study, the tidal activity and strong currents “minimize the importance of cobbles, rocks, boulders, and shells in community structure in some subtidal high-energy regimes, defying expectations from their contribution to substrate complexity.”

“You’d expect the type of environment you see in Nantucket Shoals to support a significant amount of life on its rocks and bottom features, but that’s just not the case here,” said Dr. Eric Powell, one of the authors of the study. “These findings show that we need to consider the whole range of factors when determining which habitats are most likely to support biodiversity.

”The findings are significant for future management of the Great SouthChannel area. Much of the region has been part of a HMA since 2018, which prohibits bottom-tending fishing gear. It is also home to important fishing grounds for surfclams, and is one of the most resilient areas for surfclam habitat. Surfclam fishermen have lost access to these grounds since the HMA went into full effect.

Most notably, the Nantucket Shoals area within the HMA was critical for smaller clam vessels fishing out of Massachusetts; several surfclam companies caught up to 90 percent of their harvest from the area. Since it was first established, members of the surfclam industry have argued that this habitat area does not contain enough complex habitat to justify the number of restrictions in place, especially considering the cost to the industry. The study indicates that the area may not be a good candidate for habitat protection.

“It’s important that conservation efforts target areas that are most likely to benefit them, especially if these efforts would interfere with important fishing grounds,” said Monte Rome a member of the SCEMFIS IAB. “This study helps us better identify areas that do not particularly benefit conservation efforts.”

SCeMFiS Members Attend Seafood Expo North America Following Second National Science Foundation Grant

March 15, 2019 — The following was released by the Science Center for Marine Fisheries:

The Science Center for Marine Fisheries (SCeMFiS) brings together industry and academia to conduct groundbreaking fisheries research, and is the only research center funded by the National Science Foundation (NSF) dedicated exclusively to fisheries science. As a result of its research track record, NSF awarded SCeMFiS a “Phase 2” second 5-year grant to continue its work. This funding shows that SCeMFiS met the high expectations of NSF for Phase 2 approval, a feat that not every Phase 1 center accomplishes.

Industry members of SCeMFiS will attend this year’s Seafood Expo North America and are available to be interviewed.

Factors that contributed to NSF’s determination that SCeMFiS merited a Phase 2 award included:

  • Successfully undergoing a vigorous 5-year NSF review that included external reviewers;
  • Ongoing solid support from contributing industry member companies and organizations;
  • An extremely high retention rate of contributing members;
  • The exemplary quality of research conducted by SCeMFiS principal investigators.

With its newly approved grant, SCeMFiS plans to use the next 5 years to focus on ways to reduce scientific uncertainty in fisheries science; the effects of climate change on fish stocks and fishing communities; resolving issues between fishing and offshore energy interests; and developing sound ecosystem-based fisheries management.

Since its founding in 2013, SCeMFiS has been at the forefront of finfish and shellfish research. Working with members of the fishing industry, SCeMFiS scientists have conducted innovative studies, including producing the first age-frequency distributions for ocean quahog, and being one of the only institutions to study species like chub mackerel and longfin squid.

“The work of our academic partners at SCeMFiS has been vital in improving our understanding of the species we harvest,” said Jeff Reichle, CEO of Lund’s Fisheries, which was one of the original members of the SCeMFiS Industry Advisory Board. “The more we know about these species, the better we’re able to harvest them sustainably.”

The SCeMFiS industry members attending the Seafood Expo are committed to continuing this scientific partnership. Industry members on the SCeMFiS Industry Advisory Board review, approve, and fund all SCeMFiS projects, which are selected to fill gaps in data and meet the industry’s unfilled scientific needs.

“In the last five years, we’ve been able to study and improve the understanding of some of the most pressing scientific issues facing the fishing industry,” said Center Director Dr. Eric Powell, of the University of Southern Mississippi, one of the academic members of SCeMFiS. “We are looking forward to continue our collaborative partnerships and tackle the scientific questions affecting fishermen the most.”

SCeMFiS members will be at the following locations at Seafood Expo North America:

Lund’s Fisheries: Booth 951

Sea Watch International: Booth 423

The Town Dock: Booth 2133

Seafreeze Ltd.: Booth 2407

High hopes to diversify US marine finfish aquaculture

March 13, 2019 — Spotted sea trout, wolffish, tripletail, California halibut, southern flounder, lumpfish and greater amberjack are amongst the prime candidate species that might allow for the US to diversify its marine finfish aquaculture sector.

So argued members of a distinguished panel of researchers during a special session of Aquaculture 2019 in New Orleans on 10 March – a session that offered some hope that diversification could help the country expand its marine finfish production and to reduce its $15 billion seafood deficit.

Eric Saillant from the University of Southern Mississippi’s Marine Aquaculture Centre, outlined the potential and pitfalls facing tripletail production, noting that “current data suggest that tripletail could become a successful species for commercial marine aquaculture, assuming that bottlenecks in the hatchery [phase] can be overcome.”

NORTH CAROLINA: New experiment raises possibility of fresh N.C. soft-shell crabs year-round

March 11, 2019 — An experiment to farm soft-shell crabs in North Carolina ponds could augment declining wild stocks and lead to having plenty of the delicacy fresh almost year round.

Scientists from North Carolina and Mississippi will work together in a three-year venture to raise blue crabs and harvest them for the lucrative soft-shell market.

Fresh soft crabs flood the market typically in May and June, at the height of molting season.

A $339,239 grant from the National Oceanic and Atmospheric Administration will fund the project, managed by Sea Grant programs in both states. The University of Southern Mississippi Gulf Coast Research Lab will lead the effort and lend expertise.

Science Center for Marine Fisheries Continues Work with New National Science Foundation Grant

January 23, 2019 — The following was released by the Science Center for Marine Fisheries:

Following the completion of its initial 5-year National Science Foundation (NSF) grant, the Science Center for Marine Fisheries (SCeMFiS) has been awarded a new Phase 2 grant by the NSF to continue its work. SCeMFiS will use the new grant to further its track record of quality, collaborative research with its fishing industry and academic partners.

The grant is part of NSF’s Industry/University Cooperative Research Center (IUCRC) program, which was developed to initiate long-term partnerships among industry, academia, and government. SCeMFiS is the only Phase 2 IUCRC program dedicated exclusively to fisheries and marine science research.

“Our new Phase 2 grant will allow SCeMFiS researchers to continue our collaborative work with the fishing industry,” said Center Director Dr. Eric Powell, of the University of Southern Mississippi, one of the academic members of SCeMFiS. “The Phase 2 grant will enable SCeMFiS to continue to fund the groundbreaking research necessary to maintain healthy fish stocks and healthy fisheries at a time when reliance on the best available science is increasingly critical.”

As it moves into Phase 2, SCeMFiS will focus on reducing scientific uncertainty; the effects of climate change on fish stocks and fishing communities; resolving issues between fishing and offshore energy interests; and developing sound ecosystem-based fisheries management.

“Our priorities for Phase 2 reflect the biggest challenges in the future of the fishing industry,” said Center Site Director Dr. Roger Mann, of the Virginia Institute of Marine Science, another SCeMFiS academic institution. “To meet these challenges, the industry and fisheries managers will need the kind of innovative research that SCeMFiS has regularly produced over the last 5 years.”

In its first 5 years, SCeMFiS has done groundbreaking research on finfish and shellfish. Among other projects, the Center produced the first age-frequency distributions for ocean quahog, one of the longest-lived species in the ocean. SCeMFiS scientists conducted the first benthic survey on important ocean habitat east of Nantucket, and mapped the shifting range of surfclams, documenting how climate change is beginning to affect the species.

SCeMFiS has also designed a pelagic survey for Atlantic menhaden and provided recommendations to improve port sampling for the species, carried out the only scientific work to date on Atlantic chub mackerel, and carried out an economic analysis for longfin squid.

All of these projects were reviewed, approved, and funded by the industry members on our Industry Advisory Board, who rely on sound science for the health of their fisheries and businesses.

“Fisheries management is only as good as the science it’s based on,” said Greg DiDomenico, Executive Director of the Garden State Seafood Association and a member of SCeMFiS’ Industry Advisory Board. “That’s why it’s so important for the fishing industry to maintain its partnership with SCeMFiS. We need to promote the best available science.”

Science Center for Marine Fisheries Funds Three New Projects at Fall Meeting

November 28, 2018 — The following was released by the Science Center for Marine Fisheries:

At its fall meeting in Middletown, Rhode Island, the Industry Advisory Board of the Science Center for Marine Fisheries (SCeMFiS) awarded over $164,000 in grants for promising new marine science research.

The projects cover the impact of climate change on shellfish populations; how to properly determine the age of one of the ocean’s longest-lived species; and how offshore wind energy is likely to affect fisheries. All of the funded projects further the mission of the Center, which connects leading researchers and their partners in the industry to address critical marine science needs.

As part of the National Science Foundation’s Industry/University Cooperative Research Program, SCeMFiS used this meeting to set the shared priorities of our researchers from around the country and the industry advisors from the shellfish and finfish fisheries who approved the research.

“We see this as a great opportunity to partner with the scientific community, and we are looking forward to continue working with SCeMFiS on projects that affect our fisheries,” said Meghan Lapp, the Fisheries Liaison for Seafreeze, one of SCeMFiS’ Rhode Island members.

A full description of the funded projects is included below:

  • “The influence of global warming on the Atlantic surfclam and the ocean quahog” – Dr. Eric Powell (University of Southern Mississippi) and Dr. Roger Mann (Virginia Institute of Marine Science) will lead the study, which will examine the extent to which the populations of surf clams and ocean quahogs have shifted offshore in response to changing ocean temperatures. The study will sample and date ocean quahog and surfclam shells to identify the likelihood of a continued future shift in the species’ range. ($56,197 in funding approved)

 

  • “Ocean quahog population dynamics: validation of estimation procedures for an age-at-length key – supplement” – Dr. Powell and Dr. Mann will follow up on previous SCeMFiS research on how to properly age ocean quahogs in the northwest Atlantic. Ocean quahogs can live to over 200 years old, but their growth rates vary considerably over time. The study would continue efforts to develop a reliable way to estimate ocean quahog ages at particular lengths, known as an age-at-length key. ($29,037 in funding approved)

 

  • “Oceanography special issue on the effects of wind energy development on fisheries and the ecology of the continental shelf” – Dr. Eileen Hofmann (Old Dominion University) and Dr. Powell will work to develop a special issue of the scientific journal Oceanography, that will include 10-12 peer-reviewed papers presenting an overview on the state of research related to offshore wind development. They will cover, among other topics, the challenges faced by offshore wind development and the effect it has on nearby fisheries, fish populations, and the broader ocean ecology. ($79,200 in funding approved)

Access to Surfclam (Spisula solidissima) Fishing Grounds Studied by SCeMFiS Scientists in Research Survey Cruise Southeast of Nantucket Island

August 15, 2017 — BOSTON — The following was released by SCeMFiS:

The scientists of the Science Center for Marine Fisheries (SCeMFiS) recently completed a survey of the surfclam fishery area southeast of Nantucket Island to provide information regarding surfclam stock status and habitat to ensure continued resource access by local surfclam vessels. Surveys were successfully conducted in 4 days aboard the F/V Mariette sailing from New Bedford, MA.

Chris Shriver of Galilean Seafoods in Bristol, Rhode Island commented – “We believe this survey will assist the federal managers of the surfclam industry to preserve traditional surfclam fishing areas and to assist in opening new areas for the vessels to harvest surfclams so we can supply the public with sustainable and healthy clam chowders and clam strips, while protecting the marine habitat.”

Data will be reported to the SCeMFiS Industry Advisory Board at the Fall 2017 meeting in Cape May, New Jersey, with a final report by Spring 2018 and will be considered by the National Marine Fisheries Service Northeast Fisheries Science Center (“NEFSC”) Survey Design Working Group at their September meeting. If necessary, reporting will be accelerated as required to provide input to the New England Fisheries Management Council (“NEFMC”) Omnibus Habitat Amendment 2 (OHA2) decision making process. Data collected from this cruise will contribute both to ongoing efforts to (1) preserve access to the local resource by the small boat surfclam fishermen, and (2) ensure a well informed and scientifically based decision by the NEFMC concerning delineation of Essential Fish Habitat (EFH) area closures.

SCeMFiS scientific projects are unique in that they respond directly to the scientific needs of the fisheries managers in collaboration with the commercial fishing industry while upholding strict quality scientific standards and procedures. SCeMFiS partnerships include academia, government agencies, non-profits, trade organizations, and industry members.
