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. -
No Thumbnail AvailableBook (series)Manual of Fisheries Science Part 2 - Methods of Resource Investigation and their Application 1974This document was produced in a provisional version solely for use as background documentation at the FAO/DANIDA Training Centre in the Methodology of Fisheries Science held in Frederikshavn, Denmark from 28 August to 22 September 1972. On the basis of the experience gained in using it as training material it has been revised and edited with a view to circulating it for comment by international workers in this field. This revised version will be used at the second FAO/ DANIDA Training Centre in the Methodology of Fisheries Science (Biology) to be held in Kelibia, Tunisia, from 29 July to 23 August 1974. Comments and criticisms are welcomed and should be addressed to the Aquatic Resources Survey and Evaluation Service, Fishery Resources and Environment Division, FAO, Rome.
