| Abstract/Description: | Selectivity characteristics of 35 mm diamond and square mesh cod-ends were studied from commercial trawlers off Kakinada, Andhra Pradesh. The L25, L50 and L75 of Johnius macrorhynus were 4.54, 7.04, 9.54 cm respectively for 35 mm diamond mesh cod-end, and 4.83, 7.17, 9.50 for square mesh cod-end. The selection ranges were 5.0 and 4.67 for J. macrorhynus for diamond and square mesh cod-end respectively. Selection factors for diamond and square were 2.01 and 2.04 respectively. The L25, L50, L75 values of Photopectoralis bindus were 2.30, 5.63, 8.96 cm respectively for diamond mesh cod-end and 3.85, 7.53, 11.21cm for square mesh cod-end. Selection ranges were 6.66 and 7.36 for diamond and square mesh cod-end respectively. Selection factor and selection ratio were 1.60 and 1.90 for diamond and 2.15 and 2.10 for square mesh cod-ends respectively. Overall, square mesh showed better selectivity over diamond mesh cod-end trawl net during the investigation. |
