The paper deals with the results of trawling operations conducted along the Saurashtra Coast of Gujarat State with 15.8 m six-seam otter trawl. Fishing operations carried out from Fishtech No. 8 with this new net were the first of their kind in the country and the results proved to be encouraging. The design in question is passed on to private agencies for commercial operations.

Results obtained with three trawl nets namely, 13.7m four seam, 15.8m six seam and 18.3m four seam operated from a 15.4m wooden trawler, are presented. Among the three nets operated, 15.8m six seam trawl and 18.3 four seam trawl were found to be equally effective for the capture of shrimp and during the lean season 15.8m six seam trawl can be successfully operated to exploit demersal as well as semi-pelagic fish resources. The catch data were analysed using analysis of variance and Gulland's method.
