Pillai, N G K (1985) Results of the trawling survey by an institutional Boat Cadalmin ii in the Palk bay and Gulf of Mannar, Mandapam, during 1977-80. Indian Journal of Fisheries, 32 (1). pp. 123-132.
During the course of trawling survey conducted in 1977-80 R.V. CADALMIN II (13.3 m, 100 BHP) landed from the Palk Bay and Gulf of Mannar a total ot 46,366 kg of 'all fisli" at an annual average catch rate of 57.5 kg as a result of a total fishing effort of 806.3 h. Silverbellies formed 80% of the catch. The sub-areas 9-78|lF, 9-79|2B, 2C, 3B, 3C, 3D, 4A, 4B and 4C were found to be most productive. April-June in the Palk Bay and October- December in the Gulf of Mannar were the best seasons for trawling. Over 70% of the catch came from 4-10 m depth. When compared with earlier studies, a change was noticed in the composition of fish species in this region. The estimated potential yield for all the eight sub-areas surveyed in the Palk Bay and seven sub-areas in the Gulf of Mannar was 874.6 t and 473.7 t, respectively.
