Abstract

The quantity of bycatch and discard was estimated from the landings of multiday fishing trawlers (MDF) at fisheries harbours and using the data collected onboard single-day fishing trawlers (SDF) for the period 2001-02. The quantity of bycatch generated by trawling along Kamataka coast was estimated as 56,035 tin 2001 and 52,380 t in 2002 forming 54 % and 48 % of total trawl catch respectively.
