Abstract Bycatch and discards in trawl fishing is a serious
issue that requires prompt interventions. Different
management measures are being followed to mitigate
this issue among which gear based technical
measures like BRDs are widely used. Characterization
of bycatch with regard to the type and sizes are
very important inputs for development and implementation
of any management regulation in a
fishery. The purpose of this study was to quantify
the total bycatch and also the incidence of juveniles
in the bycatch generated by commercial trawlers
operating off Central Kerala During the study, 67
species from 25 families were identified in the trawl
catch. The catch included 51 species of fishes, 7
species of shrimps, 5 species of crabs, 3 species of
cephalopods and 1 species of stomatopod. The
study also compared average length of commercially
important species obtained during the premonsoon
and post-monsoon period with that of the
Minimal Legal Size (MLS). Minimum legal Size
(MLS) is seen as a fisheries management tool with
the ability to protect juvenile fish, maintain spawning
stocks and control the sizes of fish caught. The
MLS sets the smallest size at which a particular
species can be legally retained if caught. About 84%
of the bycatch was observed to be juveniles during
the study. From the total catch observed from the
27 trawlers, 72% of the catch was targeted catch and
28% was bycatch.
