No Thumbnail AvailableBook (series)Practical guidelines for statistical monitoring of fisheries in manpower limited situations 1985The main categories and uses of fisheries-related information by fisheries administrations for stock assessment, resource management, investment, planning and economics analysis, and for social and nutritional studies are briefly discussed in this document, and the appropriate scale of these activities is illustrated using as example the constraints faced by fisheries administrators of small island states in funding and manpower in the fisheries sector. Special emphasis is placed on the type s of data that can be collected by fisheries officers, and which already exist, and are available to them from other sources. Mapping current information on the resources, the fishermen, and their employment status, the seasonality of the fishing operations, the type and number of boats and gear used, location of wharfs, landing sites, markets, shore plant and boat repair and building facilities, not to mention catches and other biological information and the main routes for transshipment a nd import/export of fish products, is a necessary first step towards considering the type and scale of statistical monitoring, and in designing a filing and monitoring system for the fishery. In planning such a system of work, the administrator will have to ensure that the fisheries officer coordinates with other organizations collecting relevant data, in order to make optimal use of existing manpower. Collection methods based on the interview approach and sampling surveys may have to be use d with care, and emphasis given instead to the commissioning of data gathering by key individuals (data sources) outside the government and strategically located within the fishery system, and to the use of simple logbooks or sales slips (which may be legislated as a requirement for licensing of fishermen or dealers). The field activities of officers should where possible, follow a present sampling design in order to maximize utility of these observations.

DocumentA report on the building up of a statistical system for the collection of marine fisheries statistics in the United Arab Emirates 1975
Also available in:
No results found.The Ministry of Agriculture and Fisheries of the Government of the United Arab Emirates is deeply involved with the development of marine fisheries in the country and to develop a statistical system which will produce appropriate statistics to measure the growth of development taking place. The types of statistics necessary for such purpose are enumerated by considering each of the three phases of the fishing industry which are: catching fish; processing, curing and preservation; marketing and d istribution. Appropriate methods for collecting data for the estimation of these statistics are also discussed. The requirements of minimum staff are also indicated. -
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.
