Abstract

The Indian tiger shrimp P. monodon is the largest species among the penaeids. For a long time there was confusion in the identification of this species. The designation of a neotype in place of the lost original type of Fabricius by Hothuis (1949) has finally resolved the century-long confusion of this species with P. semisulcatus de Haan. Although P. monodon is widely distributed throughout the Indo-Pacific region, ranging from South Africa to Southern Japan, and from Karachi to northern New South Wales, it forms commercial fisheries only in the central part of the Indo-Pacific region (Mohammed, 1970; Motoh, 1981). With an average annual landing of 915 t.P. monodon forms an important marine fishery resource in the country in view of its high demand in the export market. This species is widely distributed in the Indian waters, but forms a substantial component of the shrimp landings from the sea and the estuaries of the east coast (Jones, 1969; Silas et al., 1984). It forms the major component of the cultured shrimp production in the country because of its fast growth, hardiness and high market price. It is cultured in about more than one lakh hectares of shrimp farms with an annual production of 1, 30,000 t. This species is subjected to heavy exploitation in the estuaries and coastal waters by the capture fisheries sector primarily for exports and also for broodstock for hatcheries and for seed for the shrimp farms. In spite of its importance in the national economy, very little work has been done on its biology and fishery in its natural habitat. An attempt is made here to review the work done on the biology and capture fishery by various workers with emphasis on stock assessment and management of the resource. Full text is not available
