Abstract

Abstract: Since its sudden appearence from inadvertent introduction, Rhinomugil corsula now forms a considerable fishery wealth in Krishnagiri and Sathanur Resrvoirs, offering a new variety of fish to the consumer. The trend in the size frequency distribution, length -weight relationship and condition factor has been discussed. The uniform higher "K" factor at Sathanur Reservoir is explained with the background of the limnology of the impoundment. The fish is predominantly a mud feeder, browsing in shallow areas and ingesting very commonly algae filaments. In spite of its fluviatile nature, type instance of the species breeding under lacustrine habitat in the absence of monsoon and flood's is brought out. The present slackness in the commercial exploitation and scope for cultural possibility in Tamilnadu of the fish are elucidated.
