Summary Report of the Second FAO Expert Consultation on Interactions of Pacific Tuna Fisheries, Shimizu, Japan, 23-31 January 1995.
This publication presents the Summary Report of the Second FAO Expert Consultation of Interactions of Pacific Tuna Fisheries held in Shimizu, Japan from 23-31 January 1995. The objectives of the Consultation were to: review and integrate the outcome of the studies on tuna fisheries interactions, summarize the extent of tuna fisheries interactions and unresolved research problems and formulate guidelines for research on tuna fisheries interactions. These objectives concentrated on b iological aspects of skipjack and yellowfin tuna in the Pacific and are addressed in the Summary Report. The Consultation concluded that concerns about interactions among Pacific tuna fisheries are likely to increase as fisheries further develop in the future. The number of quantified interactions has increased, but it is still small due to difficulties associated with evaluating such interactions. The understanding of fisheries interactions has been also significantly enhanced. Tu na fisheries interactions vary in significance, depending on the biological characteristics of the species involved, the sizes of fish caught, the local and stockwide rates of exploitation, and the distances among fisheries. Based on these relationships, general qualitative guidelines on the likely extent of interactions are presented. Only specifically-designed studies may adequately quantify interactions among tuna fisheries. Comprehensive research guidelines are offered for such s tudies. Well-designed tagging experiments studies may provide the most reliable information about interactions. Guidelines for the collection of data, biological and ecosystem research, modelling, and alternative methodologies for studying tuna fisheries interactions are also included. Interactions may be reduced by decreasing the intensity of fishing, and by increasing the distances among fisheries.
