He was a stock assessment scientist for twenty years with the Northeast Fisheries Science Center in Woods Hole, Massachusetts Marine Fisheries and New York Department of Environmental Conservation. Steve’s accomplishments include the advancement of stock assessment methods for a wide range of invertebrate and finfish species, development of harvest strategies for regional, national and international fishery resources, and global leadership in evaluating geographic stock structure and modeling spatially complex populations. His teaching and research agendas focus on population modeling, stock identification, fisheries management, collaborative research with fishermen, and application of advanced technologies for fishery science.

Jim Gartland, Assistant Research Scientist, Virginia Institute of Marine Science, College of William & Mary. Jim Gartland received a B.S. degree in Marine Science & Biology from the University of Miami, and an M.S. degree in Marine Science from the College of William & Mary/VIMS. As an Assistant Research Scientist at VIMS, he is responsible for leading multiple fishery-independent monitoring surveys that operate throughout the Chesapeake Bay and coastal waters of the Mid-Atlantic Bight, as well as a large laboratory operation focused on quantifying the age structure, trophic interactions, and reproductive potential of a variety of fishes inhabiting the region. The data derived from these efforts have been used to support a number of stock assessments, and to provide greater insight into the structure and functioning of these ecosystems. Much of the success of this program has been derived from the development of lasting cooperative/collaborative partnerships with the fishing industry. Mr. Gartland serves on several technical committees and advisory panels for the Atlantic States Marine Fisheries Commission and the Mid-Atlantic Fishery Management Council.

Dr. Olaf Jensen received a BA in Biology at Cornell University and an M.S. in Marine Science at the University of Maryland Chesapeake Biological Lab and Ph.D. at the University of Wisconsin Center for Limnology. Of particular interest to SCeMFiS members is Dr. Jensen’s work in meta-analysis of fishery stock assessments. Data from fisheries represent a tremendous opportunity to learn about the dynamics of populations, communities, and ecosystems as well as fisheries management (what works and what doesn’t). Raw catch data, unfortunately, can be misleading. Stock assessments, however, are often quite informative as they combine numerous sources of information to estimate the current and historical stock size and harvest rate. In collaboration with colleagues at Dalhousie University, the University of Washington, and several other universities and government labs throughout the world, we are building a global database of stock assessments.

Dr. Rob Latour has expertise in the areas of quantitative fisheries ecology, population dynamics, and stock assessment.  He received a B.A. in Mathematics from Western New England College, and Masters and Ph.D. degrees in Biomathematics from North Carolina State University.  At VIMS, he directs a large research group dedicated to the collection and analysis of fisheries-independent data for species inhabiting the Chesapeake Bay and mid-Atlantic Bight in support of traditional and ecosystem approaches to fisheries management. Focal research areas include the use of statistical and mechanistic models to understand patterns and drivers of fish population abundance, predator-prey interactions, and community structure.  Dr. Latour has also been involved in service activities through numerous appointments on technical committees within the Atlantic States Marine Fisheries Commission, the Mid Atlantic Fishery Management Council, and the National Marine Fisheries Service.

Dr. Robert Leaf joined GCRL in September of 2012 and has expertise in quantitative methods and computer-intensive modeling approaches. The goals of these analyses are to understand population regulation and appropriate and effective conservation and management strategies. Dr. Leaf received his Ph.D. in Fishery and Wildlife Sciences from the Virginia Polytechnic Institute and State University in 2010, where he studied how phenology of individuals in harvested populations were altered under size-selective fishing. As a post-doctoral researcher in NOAA’s “Fisheries and the Environment” program, Dr. Leaf examined how phytoplankton bloom phenology determined recruitment patterns in northeast Atlantic ground fishes. His current work involves assessment of Gulf Menhaden, Gulf of Mexico Blue Crab, and Mississippi’s Red Drum stock. 

J.J. Maguire has extensive experience in stock assessment and in the provision of fishery management advice. He worked for the Canadian Department of Fisheries and Oceans from 1977 to 1996 and has been a consultant in fisheries science and management since 1996. He contributed to stock assessments related to cod (2 stocks), mackerel, redfish, pollock and bluefin tuna and reviewed stock assessments of numerous groundfish, small pelagic, large pelagic and invertebrate species. He has worked in advisory processes on the East coast of Canada and USA, in Europe, chairing the Advisory Committee on Fisheries Management (ACFM) of the International Council for the Exploration of the Sea (ICES) from 1996 to 1999 and more recently its Advisory Committee (2011 – 2013) which now provides not only fisheries advice but also advice on ecosystem and environmental issues. He worked closely with the Food and Agriculture Organization (FAO) of the United Nations on the code of conduct for responsible fisheries, on guidelines for ecolabelling and on adapting CITES criteria for marine fishes. He was a member of the team reviewing the performance of the International Commission for the Conservation of Atlantic Tuna (ICCAT) and of the General Fisheries Commission for the Mediterranean (GFCM). As a consultant he has worked for national and international, as well as fishing industry and environmental non-governmental organizations. J.J. is a member of the SCeMFiS Finfish Stock Assessment Team.

Dr. Paula Moreno established an advisory team for marine mammal assessment which also includes Dr. André Punt (University of Washington), and John Brandon (independent consultant).  Marine mammal-fisheries interactions are a serious concern of fishery and protected species management in most regions.  There are currently uncertainties in marine mammal stock abundance and bycatch estimates that urgently need to be addressed. More information on the marine mammal team can be obtained on the GCRL webpage.

Dr. Daphne Munroe studies spatial and temporal patterns of larval settlement in coastal and marine ecosystems and their influence on fished populations. Her approach to these questions uses a combination of computer modeling, field-based research and laboratory experiments. Daphne’s research examines the intersection of large and small scale processes and how it translates to changes in fished stocks over time. Jason Morson was a graduate student working with Dr. Munroe on a SCeMFiS-related project looking at sex-ratios of summer flounder discards in the recreational fishing sector.
