    Abstract

    Dorab (wolf-herrings) fishery of Gulf of Mannar and species diversity, biology as well as population characteristics of the species, Chirocentrus dorab (Forsskal, 1775) and Chirocentrus nudus Swainson, 1839 were studied to understand the dynamics of the resource, evaluate extent of their exploitation and to propose appropriate strategies for sustaining the stock and yield. Almost all gears operating along the coast exploit dorabs. About 1,142 t dorabs were landed annually during the period. Fishery was supported by two species dominated by C. dorab. Growth estimates indicated that both species grow much faster than the earlier estimates from the same region. Stock assessment shows that both species were under heavy fishing pressure and subjected to overexploitation resulting in low production below the MSY level. Strategies for enhancing stock and yield are discussed.
