Abstract

Length-frequency data for trenched sardine Amblygaster sirm (Clupeidae) from western coastal waters of Sri Lanka, obtained over a period of three years, were analyzed using the complete ELEFAN software. The mean asymptotic length and growth coefficient (K) were estimated to be 25.23cm and 1.25 year1, respectively. The instantaneous total mortality coefficient, natural mortality coefficient and fishing mortality coefficient were estimated to be 2.75 year1, 1.30 year1 and 1.45 year1, respect...
