Biology of Indian Mackerel, Rastrelliger kanagurta (Cuvier,1817) in the Western Waters of Aceh

A study of the biology of Indian mackerel, Rastrelliger kanagurta (Cuvier, 1817) in the Western Waters of Aceh, Indonesia was carried out from January to December 2014 and a total of 1343 Indian mackerels were collected randomly twice a month. The allometric coefficients (b) in the present study were between 2.625 and 3.449 with coefficient of determination (R2) values that range between 0.612 and 0.984. The condition factor (K) ranged from 0.9176 - 1.4509. Asymptotic length (L∞) and growth coefficient (K) and t0 were estimated at 27.3 cm (TL) 0.56 y-1 and - 0.526 y, respectively.  The sex ratio of male to female was 1 : 1.02. Overall, the sex ratios were not different significantly (χ2 = 26.757; df = 11 ; p < /em>
