| Abstract: | Growth and mortality in J. sina-based on the length frequency data collected during 1987-90 were computed. von Bertalanffy's growth parameters in length were estimated as L infinity = 239 mm, K = 0.777 (per year) and t(0) = -0.03814 y. This species attained 132 and 192 mm at the end of Ist and 2nd year of its life respectively. Fishery was supported mostly by zero and 1 y class individuals. The instantaneous rates of total, natural and fisihing mortalities were 4.35, 1.76 and 2.59 respectively. The exploitation rate and ratios were same (0.59). |
