Book Description
The 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 types 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 and 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 used 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.

Book Description
"These guidelines aim to help those who design routine data collection programmes, focusing on the relationship between typical questions asked by policy-makers and managers, and the data required for providing reliable answers. Fisheries policy and management objectives, particularly under the precautionary approach, need to be based upon analyses of reliable data. Data are needed to make rational decisions, evaluate the fisheries performance in relation to management activities and fulfil regional requirements. These objectives are achieved using fishery performance indicators. Indicators are used to measure the state of the resource, the performance of fishing controls, economic efficiency, socio-economic performance and social continuity. The primary factor in choosing what data to collect is the link between the necessary operational, biological, economic and socio-cultural indicators and their associated variables. The way in which different data variables are collected needs tobe tailored to the structure of the fishery. The strategy will be strongly influenced by the budget and personnel available, and the degree to which fishers and others co-operate. The programme must identify which variables should be collected through complete enumeration and which can be sampled. Collection methods are influenced by the variable itself, the strategy, collection point and the skill of the enumerator. Once collected, fishery data must be stored securely, but made easily available for analysis, which is achieved through a computer-based data management system, following the basic data processing principles. The implementation of a data collection programme should follow a normal project cycle, developing a new legal and institutional framework as appropriate"--Abstract.

Book Description
The final report forms Part I of the volume, and reviews our knowledge of distributional patterns of commercial invertebrates (conch and lobster), demersal and small and large pelagic fish stocks occurring in the Lesser Antilles subregion of the WECAF Commission area, and on the basis of existing information, places these resources in objective categories from a fisheries management perspective. The main options for management of domestic and foreign fishing are outlined. Part II contains background documents on a variety of topics, including reviews of the existing data base on invertebrates and demersal fish stocks, swordfish and oceanic pelagics. An objective classification of stocks by mode of sharing is presented, foreign fishing activity in the subarea is reviewed, and seasonality and migrations of pelagic fish discussed. An overview of options for shared stock management is also included.

Book Description
The current high demand for fish and increased awareness of the role of the environment in supporting human well being has led to a situation where attitudes to inland water resources are changing rapidly. Trends in resource use and environmental impact are very evident in inland waters which are particularly vulnerable as they act as collectors of all the activities occurring in their basins and rank as some of the most endangered ecosystems in the world. The principle changes influencing the evolution of the aquatic resource for fisheries are described in this book, which has been compiled for the Food and Agriculture Organization of the United Nations.

Book Description
The increasing shift towards co-management has prompted managers to reflect upon their new roles and reconsider information requirements. This technical paper, in two parts, is aimed to meet the growing need among co-managers for guidelines to help design and implement appropriate and cost-effective data collection programmes or systems. Part 1: Practical guide has been written specifically for co-managers and facilitators working in the field and offers simple and practical advice on helping stakeholders identify their information needs in relation to their management objectives and responsibilities, and developing collaborative ways of collecting and sharing the information in the most effective way. (Part 2 is ISBN 92-5-105410-X)
