Research Dollars For Thread Herring, Squid, & Surf Clams - The Fisherman

Research Dollars For Thread Herring, Squid, & Surf Clams

The Science Center for Marine Fisheries (SCEMFIS) has funded $126,000 in new marine science research for 2022. The funds, approved by the members of the Center’s Industry Advisory Board at its annual fall meeting, will support new, much-needed research on prominent fisheries such as thread herring, ocean quahogs, squid, and surf clams.

The following research projects were approved by SCEMFIS for 2022:

Biostatistical and fishery-dependent sampling of Atlantic thread herring and Atlantic chub mackerel in the mid-Atlantic region.  As a result of climate change and the subsequent migration of fish stocks, a fishery for Atlantic thread herring is developing in the Mid-Atlantic. As part of that development, fisheries managers need better biological data on the species in order to manage it sustainably. This project, led by Dr. Robert Leaf (University of Southern Mississippi), will conduct a sampling survey of thread herring to collect data on the fish being harvested by the fishery, including factors such as age, length, and weight. ($69,336 in funding)

Ocean quahog population dynamics: project completion. SCEMFIS researchers have worked extensively at expanding our understanding of ocean quahog, especially work in charting the age frequencies for quahogs in the Northwest Atlantic, as well as measuring the uncertainty that comes with estimating the age-at-length of quahogs. This project, led by Dr. Eric Powell (University of Southern Mississippi), and Dr. Roger Mann (Virginia Institute of Marine Science), will complete the Center’s ongoing work on ocean quahog, finishing and publishing current unpublished research on quahog age frequencies. ($41,210 in funding)

Genetic and age structure of Southern surf clams. The surf clam fishery has recently resumed fishing in the waters off the coast of Virginia in a region where high bottom water temperatures have led to the deaths of most Atlantic surf clams during much of the 2010s. Increased survival recently may be due to recruitment of the Southern surf clam. To better understand how and why surf clams have returned to this area, this project, led Dr. Daphne Munroe (Rutgers University), will conduct genetic testing on a sample of clams from the area. The tests will help determine their relationship with the rest of the coastwide Atlantic surf clam stock. ($10,795 in funding)

Squid age estimation using CAT Scan technology.  A recurring challenge in managing squid is the lack of demographic data available to estimate the ages of the squid in the population. This project, led by Dr. Roger Mann, (Virginia Institute of Marine Science), will evaluate the use of CAT scan technology as a tool to age squid. The scans will be used to measure the size of squid statoliths, which are the hard structures in squid heads that grow over time, and attempt to age the squid based on these measurements. ($5,000 in funding).

Part of the National Science Foundation’s Industry-University Cooperative Research Centers program, SCEMFIS connects marine scientists with members of the fishing industry to identify scientific priorities for better understanding commercially important fish species, and directs industry funding to projects that study them. Since its founding, SCEMFIS has promoted research that has increased our understanding of these species, and improved their management.

SCEMFIS university partners, University of Southern Mississippi (lead institution), and Virginia Institute of Marine Science, College of William and Mary, are the academic sites. Collaborating scientists who provide specific expertise in finfish, shellfish, and marine mammal research, come from a wide range of academic institutions including Old Dominion University, Rutgers University, University of Massachusetts-Dartmouth, University of Maryland, and University of Rhode Island.
