Abstract
Length frequency of sardine, Sardinella longiceps (Valenciennes), caught in gill nets with
mesh size of 32, 34, 36, 38 and 40 mm operated off Cochin (Kerala) was recorded. Using
this, the selectivity parameters of the nets of these mesh sizes were assessed. The size range
of S. longiceps caught was 12 to 20 cm. The estimated selection factors ranged from 4.56 to
4.67 and the selection lengths ranged from 14.7 to 18.7 cm. Gill nets with mesh size less
than 34 mm did not facilitate the escapement of S. longiceps which had not attained the
stage of first maturity
