Abstract

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.
