Abstract
Fishing conducted in inshore waters off Thoothukkudi (Tamil Nadu) during 1997-98
using 16 units of nylon gill nets with 26, 28, 30 and 32 mm mesh size made up of 210D/
1/2 twine revealed that the proportionality co-efficient (k) of the gill net selectivity equation
for Sardinella gibbosa was 0.104. Gill net with mesh size 29.6 mm was found to be ideal
for the commercial exploitation of S. gibbosa which contributes considerably to the lesser
sardine fishery of Thoothukkudi coast. The details of enmeshing pattern of different length
groups of S. gibbosa in gill nets of different mesh sizes are presented
