Description |
The introduction of mechanised trawlers to exploit the demersal resources beyond the traditional fishing grounds of Kerala in the early fifties was an important event in the marine fisheries of Kerala and due to its high returns it became widespread all along the trawlable coastal grounds. As it is found as the most efficient method for the exploitation of shrimps and therefore, its number has shown an exponential increase along the coastal waters of Kerala. Among the mechanised boats operating along Kerala coast more than 90% belong to bottom trawl specifically aimed for the exploitation of shrimp resources of the inshore waters (Ravindran and Baiju, 1998). Kurup and Radhika (2003) enumerated the number of bottom trawlers operated from 11 major and minor fisheries harbours of Kerala as 4960.Bottom trawling being a non selective fishing gear, it hauls up all the organisms dwelling at the sea bottom and therefore, its destructive effect to the non target organisms of the sea bottom is a matter of grave concern on a global basis (Jennings and Kaiser, 1998). |
