Abstract

Resource characteristics of the two commercially important scada Decapterus
russelli and D. macrosoma were studied at Vizhinjam area from 1993 to 1995.
Detailed analyses were made on catch composition among carangids, catch-
CPUE relations of these species and total carangids in different gear-craft
combinations, and the efficiency of these gear units on the catch of these
species. D. russelli dominated the carangid fishery followed by D. macrosoma
averaging 30 and 10 percentages respectively. Hooks and line gear operated
from mechanised crafts was found to be the most efficient gear for carangids,
in particular for D. russelli. A comparison was made between the catch rates
of the different gear-craft combinations in the two species. These results are
discussed highlighting the effect of mechanisation on the catch and catch rate
and suggest stock assessment to check whether the stock of these commercially
important species are overexploited.
