No results found.This publication presents papers and discussions of the First FAO Expert Consultation on Interactions of Pacific Tuna Fisheries held in Noumea, New Caledonia from 3 to 11 December 1991. The objectives of the Consultation included: the identification and documentation of concern related to interactions among fisheries directed at tuna and tuna-like species in the Pacific, the classification of these interactions, the review of information on them and methods for their study, and the formu lation of recommendations for future research. Volume 1 contains: the Summary Report of the Consultation, a review paper on methods for studying interactions in tuna fisheries,thirteen papers presenting new methods and case studies on such interactions, and seven reviews on fisheries interactions related to individual stocks of Pacific tuna and tuna-like species. Volume 2 includes: eleven review papers on the biology, population dynamics and fisheries associated with the stocks o f Pacific tuna, which are supplemented by four additional papers on specific fisheries. The information contained herein demonstrates the potential for interactions occurring between and among the fisheries directed at tunas and tuna-like species. Empirical evidence for such interactions, however, has been available for only few fisheries, and these interactions have been quantified for even fewer fisheries. It is unclear whether interactions are insignificant among fisheries directed at t una and tuna-like species or whether scientists are unable to detect these interactions possibly due to various changes to fisheries and resources, resulting in a too-variable background which conceals the effects of interactions. -

No results found.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. -

No results found.This publication includes forty papers and two abstracts of papers presented at the Second FAO Expert Consultation on Pacific Tuna Fisheries held in Shimizu, Japan, from 23 to 31 January 1995. The topics of the papers include: · reviews of tuna fisheries interactions and their research including methods for their study, · new methods for studying tuna fisheries interactions and examination of their applicability, · case studies on tuna fisheries interactions, · analyses of tuna fisheri es involved in interactions and their management, and · an overview of FAO’s project that co-organized and co-sponsored the Consultation. A supplement of an indexed bibliography of papers on tuna and billfish tagging, which was printed separately, is also included. 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 · fo rmulate guidelines for research on tuna fisheries interactions. The understanding of tuna fisheries interactions was enhanced significantly by recent studies. However, the Consultation noted that the number of quantified interactions is still small due primarily to difficulties associated with evaluating such interactions. The papers providing supporting information for the conclusions of the Consultation are presented in this publication. Interactions were found to vary in significance depend ing on the biological characteristics of the species involved, the sizes of fish caught, the local and stock-wide rates of exploitation, and the distance among fisheries. In many of the studies presented, the inadequacy of fisheries data was stressed. In addition, the lack of understanding of movements of the fish being studied was noted in several papers. General qualitative guidelines presented in several discussion papers stressed that specifically-designed studies be undertaken to adequately quantify interactions. Well-designed tagging experiments were thought to 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.
