A review of experimental trawling from small and medium sized mechanized vessels off Kanikada

The most suitable otter trawl for small boats was found to be a 10.9 to 15m 2-seam trawl with 100cm x 50cm x 35kg horizontally curved otter boards together with long single sweep line. For operation from medium sized trawls, 18.26m 2-seam 18.3m 4-seam and 29.26m long wing trawl were found suitable. An 18.3m 4-seam trawl was netting a considerable quantity of off-bottom fishes. Shrimps predominated in the catches of the 29.26m trawl. Productive grounds for Cynagris species, Psenus species and Decapterus species within 50 to 100m depth ranges off Kakinada were available for profitable exploitation.
