No Thumbnail AvailableBook (series)Small pelagic fishes and fisheries in African inland waters / Espéces de petits pélagiques el leurs pecheries dans les eaux intérieures de l'Afrique 1984

No results found.This is a brief review of small pelagic fishes and fisheries of Africa's large lakes and reservoirs. Small pelagic fishes have an important role to play in increasing Africa's inland water fish supply because the available potential generally has been underutilized. Pelagic communities in African inland waters usually consist of small zooplanktivorous species and a group of predators which feed upon them. In addition to being small these prey fishes usually have a short life-cycle and high produ ctive potential. There are four major families which include pelagic species with actual or potential fishery importance in Africa. The general biological characteristics of these species are discussed and the major pelagic fisheries in Africa are described. -

A preparatory meeting
1984Also available in:
No results found.The papers contained in this supplement cover theoretical aspects of fisheries management and its practice in a general manner. Two aspects of fisheries management are reviewed from the perspective of the market for fish and from the fishermen's view. The majority of the papers discuss specific regulatory techniques such as fixed fishing gear, selectivity of fishing gears including mesh size regulation, controls over numbers of fishing vessels and the effects of various financial measures. Sever al of the papers examine approaches to fisheries regulation that attempt to overcome the common property aspect of fisheries resources. The last paper re-examines the basic equilibrium theory that is applied to most fisheries. -
