Spatial Dynamics In Fisheries Stock Assessment, Yong Chen

University of Maine Office of Research Administration: Grant Reports

Most fisheries stock assessments assume that the spatial distribution of fish and/or fishing effort is random (Hilborn and Walters 1992), even though this is rarely the case (Paloheimo and Dickie 1964, Caddy 1975, Hilborn and Walters 1992, Tilzey 1994, Hutchings 1996, Chen et al. 1998, Hart 2001). The target stock is often aggregated and the distribution of fishing effort reflects this spatial pattern, along with other factors such as management restrictions, distance to port, vessel size, and the experience and habits of individual fishers. This often results in high spatial variation in fishing effort and mortality.

Ignoring this spatial variation …

Small Fishing Ports In Southern New England, Report To The National Science Foundation, Volume Ib, James Acheson, John T. Poggie Jr., Richard B. Pollnac

University of Maine Office of Research Administration: Grant Reports

Social and cultural aspects of fisheries management were examined to establish basic data on the fishing communities and fisheries of southern New England. Five small ports were selected for study--Newport, Chatham, and Westport, Massachusetts; Newport, Rhode Island; and Stonington, Connecticut. These ports differ in terms of local, social, and geographical conditions, fishing styles, and emphases. Results of the study show that these ports act as a backup for the industry as a whole by (1) providing sources of fish for local markets; (2) using low energy models which reduce energy costs; (3) allowing individual fishermen a greater opportunity to find …

A Model Of Adaptive Behavior In The New England Fishing Industry, Report To The National Science Foundation, Volume Iii, James Acheson, James A. Wilson

University of Maine Office of Research Administration: Grant Reports

This volume is the third in a three volume series of reports submitted to the National Science Foundation for a project entitled "University of Rhode Island, University of Maine Study of Social and Cultural Aspects of Fisheries Management Under Extended Jurisdiction" (N.S.F. Grant Number AER77-060l8). This project was funded through the RANN Directorate of N.S.F. (Research Applied to National Needs), and was designed to provide data on social, cultural, and economic aspects of the New England fishinq scene which would be of value to those in industry and government concerned with managing the marine fisheries of the northeastern part of …

The Fishing Ports Of Maine And New Hampshire: 1978, Report To The National Science Foundation, Volume I, James Acheson, Ann Acheson, John R. Bort, Jayne Lello

University of Maine Office of Research Administration: Grant Reports

This volume is part of a final report on social science aspects of fisheries management in New England and is divided into three sections. In Section I, general background information is given concerning aspects of the fisheries in northern New England. Included is a history of fishing in the area, general information on the coastal environment and biology of major species caught and a background on fishing boats and gear, marketing and processing, and the legal environment. Section II describes each of the ports in Maine and New Hampshire, as they were in the baseline year of 1978, outlining the …

Essays On Social And Cultural Aspects Of New England Fisheries: Implications For Management, 1980 Final Report, Volume Ii, James Acheson

University of Maine Office of Research Administration: Grant Reports

This volume provides baseline data on the fishing communities and fisheries of New England, information on key values and social institutions, and a model for applying social science information to problems of fisheries management. Articles presented on institutions and values range from discussions of occupational commitment and types of fishermen and fish markets to studies of fishermen's wives and kinship. Several types of innovation, including a metal lobster trap and electronic fishing gear, are reported, and the social and economic factors that determine their adoption or non-adoption are considered. Four articles on applications of social and economic information to specific …
