Proceeding of the Second FAO Expert Consultation on Interactions of Pacific Tuna Fisheries Shimizu, Japan 23 to 31 January 1995

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. -
Book (series)Chronicle of Cuban marine fisheries (1935-1995) Trend analysis and fisheries potential 2000
Also available in:
This technical paper presents an analysis of trends in the Cuban marine fishery resources as described by a data set that covers the 1935 to 1995 period. Despite the biases that undoubtedly exist in national fishery statistics and the low level of disaggregation for some groups of species, the extended data set offers a comprehensive picture of Cuban fisheries over 60 years and makes it possible to trace down the phase of development as well as the phase of greatest expansion of Cuban fisheries. The data set shows the sustained increase of catches from the mid-1950s to the 1970s, the decrease in the growth rate during the 1980s and, starting in the 1990s, the senescence of some important fisheries. In 1995, about 38.9 percent of the resources were in a senescent phase (with consequent declining catches), 48.7 percent were in a mature phase at a high exploitation level and only 12.4 percent were still in a developing phase with some possibility of increased catches; none of the fisher ies remained undeveloped. Hence, 87.6 percent of the fishery resources are in a critical stage from the point of view of fishery management and, therefore, there is an urgent need to control and reduce the fishing effort. -
Book (series)The state of world fisheries and aquaculture - 1994 (SOFIA) 1995This report reviews the state of world fisheries and aquaculture in 1994, with particular attention to developments since 1989. Following consideration of world fish production and growth in demand for fish, marine fisheries production and issues are addressed in detail. Problems of fleet overcapacity and overinvestment in marine capture fisheries, leading to an unsustainable impact on resources, are highlighted. An analysis of inland capture fisheries and aquaculture is presented, noting that aquaculture will be expected to play a greater role in the food security equation in future. Fish utilization and the fish trade are reviewed. The report also provides a regional analysis of supply and demand prospects. It ends with an outlook on the prospects of satisfying global demand for food fish to the year 2010.
