Current Research Support:
1. Development and Application of Precautionary Harvest Control Rules:
A recent initiative in fisheries science is the implementation of a precautionary approach to fishery management. Through individual stock assessments and collaborative working groups at regional and international levels, I helped to formulate precautionary harvest control rules for dozens of marine fish stocks. As a member of the Overfishing Definition Review Panel for the New England and Mid Atlantic Councils, I helped to advise on overfishing reference points and control rules for 35 stocks off the northeast U.S. Subsequently, as a member of several Stock Assessment Review Committees and the Working Group on Re - Evaluation of Biological Reference Points for New England Groundfish, I was instrumental in providing advice on reference points for many northeast fish stocks. As a participant in several Northwest Atlantic Fisheries Organization (NAFO) workshops on the Precautionary Approach, I helped to develop a precautionary framework for management advice and was active in developing precautionary reference points for several stocks. As a member of the Advisory Committee on Fishery Management for the International Council for the Exploration of the Sea (ICES), I help to develop precautionary reference points and provide annual management advice for 163 management units. I am currently a member of the National Standard 1 Guidelines Working Group, tasked with revising national standards on avoiding overfishing and rebuilding depleted fish stocks.

2. Advancement of Stock Assessments:
I improved stock assessments of several resources in the northeast. I led the development of the first analytical assessment of Gulf of Maine shrimp using biomass dynamics and Collie - Sissenwine analysis, which has been the basis of management for that stock for the last ten years. During a period of poor sampling for age - based analysis of Georges Bank yellowtail flounder, I collaborated with Canadian scientists on the development of a biomass dynamics model, which has helped provide reliable management advice during a successful rebuilding period. I led a collaborative effort between the Center and the state of Massachusetts in the development of the first analytical assessment of Cape Cod yellowtail flounder. Although there are considerable uncertainties in the assessment, it remains the basis of management for that stock. I developed the first analytical assessment of longfin squid and contributed to basic research on distribution and reproduction dynamics. I contributed to stock assessment of many resources through the Northeast Regional Stock Assessment Workshop, the North Pacific Stock Assessment Review process, ICES Sub - Groups and the Scientific Council of NAFO.

3. Stock Identification:
I have researched geographic stock structure of many fishery resources. I developed morphometric methods for stock identification and applying advanced methods to American lobster, Atlantic herring, Atlantic salmon, yellowtail flounder, and longfin squid. I also coordinated the description and development of the many disparate disciplines of stock identification research through co - chairmanship of the ICES Stock Identification Methods Working Group and lead editor of "Stock Identification Methods" a book published by Elsevier Academic Press. I was also co - convener of the Groundfish Distribution and Stock Structure Workshop of the 2001 U.S. - Canada meeting and was convener of a theme session on stock identification methods at the 2004 ICES Annual Science Conference. I am currently on a steering committee to plan a NMFS Management Units workshop and a coauthor of an agency policy paper on management of biological stocks.

4. Yellowtail Flounder Tagging:
I coordinate a cooperative tagging study with New England fishermen, state fishery agencies and research institutes to tag yellowtail flounder with conventional disc tags and data - storage tags with the objectives of estimating movement among stocks areas and mortality within stock areas as well as providing growth observations. The tagging study was designed to address the major uncertainties in the Cape Cod - Gulf of Maine, Georges Bank and southern New England - Mid Atlantic yellowtail stock assessments. I administered vessel contracts, managed the program budget, and supervised technicians, contractors and interns. Over three years, 35 000 yellowtail were tagged, and approximately 5% of those were recaptured per year. Preliminary results indicate frequent movements within stocks with a low frequency of movement between stock areas. Information obtained from data - storage tags documents frequent off - bottom activity associated with movement to different habitats. The research is considered to be a successful venture between fishermen and scientists to address important fishery science and management problems.
