Abstract Penaeid prawns are distributed worldwide in tropical and temperate latitudes (Holthuis, 1980). The family Penaeidae is arguably the most valuable group of marine species in the world. Although annual stock sizes fluctuate widely, few stock recruitment relationships have been demonstrated for the family (Garcia, 1983 and1985) and the role of the environment in larval and post larval mortality is poorly known. The biological management of prawn stocks is frequently limited by inadequate knowledge of factors affecting production. An understanding of the basis of resources renewal provides a back ground for management direction. |
