Abstract
The Present study evaluates the effect of 45 days seasonal ban on trawl catch along the Chennai coast, Tamilnadu. The CPUE from commercial trawler, which was carried out before seasonal ban (June-August
1999) was compared with the CPUE in trawling done 4 years later (June-August 2001). Sampling was based on 15 hauls from 3 depth strata, viz., 10-50.51-100, 101-150 m before and after the seasonal ban Records of catch data from 15 hauls before seasonal were taken from commercial trawler's catch log book. Subsequently, 15 hauls were made between June and August 2003 from the same trawler. Eleven
commercially important targeted species (nine finish, one crustacean and one cephalopod) were used for comparison. The average total catch of selected species was increased by 37% .The catch increment was
from 7% in sciaenid to 72% in silver bellies after 4 years of implementation of seasonal trawl ban. Fishery management strategics based on seasonal trawl ban may be useful in areas where demersal trawl targeting multi species.
