| Popis: | Shrimp fisheries in tropical countries concern chiefly the members of penaeid family. The industrial and small-scale sectors both fish the same resources at the same time using different fishing methods. They often compete with each other or with other fishery sectors. This paper deals with the methods of production of these two sectors and includes descriptions of the main fishing methods used. Description of the most popular trawls used in industrial fisheries and the selective devices which have recently been developed in an attempt to reduce fish catches are included. With regard to small-scale fisheries, where there is a wide variety of fishing methods, only the most commonly used methods are described. As accurate information as possible is then given on selectivity and efficiency of different fishing gears. The recommendations refer to fishing technology; certain lines of research are suggested and the need to develop an extension service is stressed. (Résumé d'auteur) |
