Abstract

The trawling is carried out almost throughout the year in the inshore water except for peak monsoon months. Their nonoperation is chiefly due to the unfavourable sea conditions or bans imposed by the governments as in Kerala, Tamilnadu, Andhra Pradesh or socially self-imposed ban as in Karnataka. The excessive fishing pressure exerted by the mechanized / motorized sector in a climatically limited coastal habitat up to a depth of about 50 m have not only affected the sustenance of some easily vulnerable resources, but also challenged the very existence of some shell fishes, fin fishes and bottom organisms, including the biota which are non-edible to man but vital in the food web of all exploitable resources. The present account pertains to the impact of the gear along the south-west coast (Karnataka and Kerala) trawling grounds preferably on the non- target by catch.
