Abstract
The cod end of trawl is often filled with large quantity of jelly fish during post monsoon
period, resulting in gear damage or abandoning of the catch. A new technique of incorporating
large mesh (70-90 mm) false cod end extending between the throat and up to 2/3rd length
of cod end effectively separated jelly fish from the target species facilitating the discard easier.
Onboard tests proved the possibility of saving the catch almost completely without damaging
the gear.
