A note on the changing catch trend in the traditional Trap-fishery of Keelakarai and Rameswaram

Abstract

The catch composition, the size composition of the fish and the seasonal variation of the fishery show that the catch trend in the trap fishery has slightly changed, for the better, at both Keelakarai and Rameswaram with the use of prawn peelings (wastes from the recently developed prawn industry) as bait. A brief observation' on the biological aspects of Siganus canaliculatus, a dominant constituent at present, is also given.
