This paper reports on the findings of fishing trials with one-boat bottom trawls conducted from Chandipur, in Balasore district, Orissa, in 1984/85. Detailed specifications and designs of some of the trawls are given. Trials during 65 fishing days clearly demonstrated the superiority of the high opening bottom trawls over the conventional bottom shrimp trawl. The trials were conducted along commercial lines employing private trawlers. The cooperating agency in Orissa was the Directorate of Fisheries. The Orissa fishing trials were part of a wider project organized jointly by the small-scale fisheries project of the Bay of Bengal Programme (BOBP) and the Government of India for developing and introducing high-opening bottom trawling for food fish and shrimp. Two earlier working papers (BOB P/WP/10 and BOBP/WP/20) document trials conducted in Tamil Nadu, while one other paper (BOBP/WP/21) suggests improvements to the deck machinery and layout of small coastal trawlers. |
