No Thumbnail AvailableBook (series)Status of Interactions of Pacific Tuna Fisheries in 1995
Proceeding of the Second FAO Expert Consultation on Interactions of Pacific Tuna Fisheries Shimizu, Japan 23 to 31 January 1995
1996Also available in:
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)Small pelagic fishes and fisheries in African inland waters / Espéces de petits pélagiques el leurs pecheries dans les eaux intérieures de l'Afrique 1984
Also available in:
No results found.This is a brief review of small pelagic fishes and fisheries of Africa's large lakes and reservoirs. Small pelagic fishes have an important role to play in increasing Africa's inland water fish supply because the available potential generally has been underutilized. Pelagic communities in African inland waters usually consist of small zooplanktivorous species and a group of predators which feed upon them. In addition to being small these prey fishes usually have a short life-cycle and high produ ctive potential. There are four major families which include pelagic species with actual or potential fishery importance in Africa. The general biological characteristics of these species are discussed and the major pelagic fisheries in Africa are described. -
No Thumbnail AvailableBook (series)Papers presented at the Expert Consultation on the regulation of fishing effort (Fishing mortality)
A preparatory meeting
1984Also available in:
No results found.The papers contained in this supplement cover theoretical aspects of fisheries management and its practice in a general manner. Two aspects of fisheries management are reviewed from the perspective of the market for fish and from the fishermen's view. The majority of the papers discuss specific regulatory techniques such as fixed fishing gear, selectivity of fishing gears including mesh size regulation, controls over numbers of fishing vessels and the effects of various financial measures. Sever al of the papers examine approaches to fisheries regulation that attempt to overcome the common property aspect of fisheries resources. The last paper re-examines the basic equilibrium theory that is applied to most fisheries.
