Abstract

The worldwide shrimp landings in 1988 were reported to be 2.484.000 tons an increase of about 460.000 tons compared with 1985. The majority of shrimp fishing areas located in the tropical and sub-tropical regions with a contribution of more than 2 million tone. The most important species are the shallow water Penaeid shrimps. This quantity of about 2.5 million tons represents approximately 3% of the world marine catch. In terms of value, it represents almost 30% of the world trade in fish products. Main management objectives include: long term resources conservation; to maximize physical catches; to maximize the total income from catches or foreign exchange; to maximize economic profits; to reduce the shrimp by catch or improve its utilization; other social and economic interests. These objectives are in part interconnected and some are in conflict. Resource conservation is a basic condition for all other management objectives. Management policy definition should be in accordance with national goals and based on available scientific knowledge of the resources and of the fishing industry. The definition and selection of management objectives is an important process, to which the scientists must contribute the best way they can, mainly in providing the necessary information and options for management.
