Abstract
Growth parameters were estimated for three species of silverbellies from the south-east coast of India, based on samples collected from trawl landings at Kasimedu Fisheries Harbour in Chennai. Asymptotic length L, annual growth co-efficient K and theoretical age of the fish at zero length t0, were derived as 139.9 mm, 1.41 yr-1 and -0.119 yr for Photopectoralis bindus, 121.5 mm, 1.525 yr-1 and -0.01212 yr for Secutor insidiator and 166.65 mm, 1.3 yr-1 and -0.0159 yr for Gazza minuta. Average daily growth rate ranged between 0.45 mm and 0.13 mm in P. bindus, 0.34 mm and 0.03 mm in S. insidiator and 0.62 mm and 0.1 mm in G. minuta. At the end of the 1st and 2nd year of its life, P. bindus attains lengths of 110.5 mm and 132.3 mm, S. insidiator, 94.9 mm and 115.6 mm and G. minuta, 122.1 mm and 154.5 mm. Longevity was estimated as 2-2.2 yrs for P. bindus and S. insidiator and 2.4 yrs for G. minuta.
