No Thumbnail AvailableBook (series)Technical studyPrinciples of hydraulic management of coastal lagoons for aquaculture and fisheries 1990
Also available in:
No results found.This document is prepared for fisheries biologists, managers and administrators concerned with lagoon fisheries and aquaculture. Our main objective is to draw attention to the need for greater understanding of relationships between the hydraulics and productivity of lagoon fish and shellfish. The fishery yields from lagoons vary widely, and, probably, predictably, once such relationships are understood. Furthermore, the productivities of many lagoons could probably be enhanced by hydraulic manip ulations, but the hydraulic manipulation is presently risky, except in dystrophic lagoons. The document includes a description of lagoon physics, how hydraulics are likely linked to lagoon productivity, how lagoons might be expected to respond to hydraulic alterations, and a protocol for physical investigations. This latter is a necessary step to protect as well as enhance fisheries and aquaculture resources in lagoons, which are especially vulnerable to degradation and overexploitation. -

Book (series)Technical reportReport of the Expert Consultation on Identifying, Assessing and Reporting on Subsidies in the Fishing Industry - Rome, 3-6 December 2002 2003The Expert Consultation on Identifying, Assessing and Reporting on Subsidies in the Fishing Industry met at FAO Headquarters for four days starting 3 December 2002. The consultation reviewed an FAO guide for identifying, assessing and reporting on subsidies and concluded that with minor modifications the guide is ready for use. It recommended that FAO support Members in undertaking studies based on the guide. The experts considered it important that available methodologies be used to assess im pacts flowing from actions taken by recipient of subsidies on environment, trade, economic growth and social conditions. The consultation concluded that FAO should promote the development and use of appropriate models for the evaluation of impacts of subsidies through actual case studies.
