On the seasonal growth, monthly recruitment and monthly biomass of Peruvian anchoveta (Engraulis ringens) from 1961 to 1979

The paper reports on the application to the anchoveta of a newly developed set of methods for the investigaton of exploited fish stocks. the set of methods are incorporated in the ELEFAN (Electronic Length Frequency Analysis) programs developed at ICLARM, which are applied to catch-at-length data from the Northern region of Peru and covering the years 1961-1979.

Fishermen's knowledge as background information in tropical fish ecology: a quantitative comparison with fish sampling results

An investigation of fishermen’s knowledge of fish occurrence patterns on various spatio-temporal scales has been realized in the Fatala Estuary (Guinea, West Africa), accompanied by a one-year survey with standardized gill-net sets. Seventy one fishermen distributed in four zones corresponding to gill-net sampling sites were questioned about seasonal variations of species’ relative abundances. Longitudinal and seasonal patterns of fish relative abundances were described with correspondence analysis and ANOVA for both approaches.

FISHBASE: an information system to support fisheries and aquaculture research.

The International Center for Living Aquatic Resources Management (ICLARM) in collaboration with the Food and Agriculture Organization of the United Nations (FAO) and with the support of the Commission of the European Communities is developing a database (called FISHBASE) to summarize global information on living aquatic resources (fish, crustaceans and molluscs) in a standardized form to be made available on CD-ROM to institutions in developing countries.

Assessing and managing the marine fish resources of Sierra Leone, West Africa

A joint Sierra Leone/1CLARM project funded by the Commission of the European Communities is presented, whose task is to assemble the available survey and fisheries data on the marine fish resources of Sierra Leone, analyze them, and based thereon, propose a management regime for these resources. The computerized databases and other tools developed for this purpose and for monitoring and analyzing the fisheries after the project has ended are presented, and their potential use in neighboring countries is discussed.

Fishery resources accounting in the Philippines.

The conventional system of national accounts does not recognize or include environmental or natural resource as inputs to production such that It responds poorly to changes in environmental and resource conditions. Also, it fails to reflect the efforts to solve environmental problems and efforts to clean up the problem. The author of this papr takes a look at Gross National Product from a different perspective.
