John Mandelman: Solving a Cod-undrum

WED, MAY 28, 2014 (1:08:18)

The Atlantic cod'a culturally, economically and ecologically important fish species with a rich New England history'has not recovered from stock collapses in recent years, despite substantial management intervention and a major reduction in commercial fishing effort. Although research attention has increased, many questions on cod meant to aid management and promote recovery are not yet fully answered, such as what happens to those cod that are caught by certain fishing gears, but not harvested. Dr. John Mandelman describes ongoing work by the New England Aquarium and colleagues to better understand the fate of undersized cod that by law must be released after capture in recreational fisheries, and which strategies may increase the probability of survival. Dr. Mandelman also provides historical context on cod in the region, and describe how evolving tracking technologies are being used to answer important fisheries questions.

John W. Mandelman, Ph.D. Research Scientist (at NEAq in various positions since 2001) B.A. University of Rochester, 1996, Psychology Ph.D. Northeastern University, 2006, Biology

Research Interests: stress physiology of elasmobranch fishes (sharks, rays and skates), applied fisheries biology, and physiological ecology of fishes. More specifically: 1) the physiological alterations caused by stress in elasmobranchs and other finfish; 2) the mortality of discarded bycatch in fishing operations; 3) strategies to reduce the incidental capture of elasmobranchs; and 4) movement and distribution of marine finfish around artificial structures (i.e. fish aggregation devices).

Current Projects include: The immediate and delayed mortality of western North Atlantic skates due to fishing capture (funded by NOAA Fisheries Northeast Region); impacts studies on the exclusion zones associated with deepwater liquid natural gas (LNG) terminals in Massachusetts Bay (Funded by Excelerate Energy, L.L.C. & Suez Energy North America, Inc.).
