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. -
Book (series)A review of the inland fisheries of India 2024
Also available in:
No results found.India has abundant water resources including rivers, canals, ponds, lakes, reservoirs, upland lakes, and floodplain wetlands covering over 5.8 percent of the country. These environments harbour a rich fish fauna of 1 035 species that constitutes the basis for the inland fisheries sector, which annually produces 2 144 452 tonnes of fish – if enhanced and culture-based fisheries are included – corresponding to 21 percent of total fish production. Rivers like the Ganga, Brahmaputra, and Barak, alongside floodplain wetlands, play crucial roles, especially in the east and northeast. Lakes are abundant in upland areas. Reservoirs cover over 1 percent of India's land and hold untapped potential for fisheries development. Traditionally, fishing in inland water bodies has been a small-scale or subsistence activity. Fishing practices, crafts and gear used in inland fisheries are still traditional. Cooperative societies are present in reservoirs and wetlands giving fishers better bargaining power with traders and better prices for the fish. Inland fisheries are imperative for poverty alleviation, food security, gender empowerment, cultural services, ecosystem function, and biodiversity, and are important for achieving the Sustainable Development Goals. Important threats to inland fisheries include water scarcity, habitat loss, pollution, climate change and invasive species. However, several major river conservation programmes have been initiated.The collection of inland fishery catch statistics remains weak and production appears to be significantly under-reported in many states. A simplified method for defining water bodies and estimating catch is proposed and all States have been advised to follow the same definition for water bodies. -
Book (stand-alone)Kapenta rig survey of the Zambian waters of Lake Kariba 2014
Also available in:
No results found.This survey revealed the huge extent of overfishing of kapenta that is occurring on the Zambian side of Lake Kariba and the rate at which this problem is expanding. It can be confidently reported that there are at least 950 boats but more likely over 1000 on the Zambian side of Lake Kariba. This is four times the number of vessels estimated to keep fishing at the original maximum sustainable yield. Rapid action is required to prevent further collapse of the kapenta fishing industry and it is the refore important to highlight the lack of enforcement and the lack of resources within Local Government and DOF to police these waters. This lack of enforcement is identified to be one of the leading problems. The DOF do not appear to have any record of the number of rigs registered legally on the lake.
