Abstract

The present study was carried out length-weight relationship for four commercially important fish species namely Lates calcarifer, Otolithoides pama, Polynemus paradiseus, and Tenualosa ilisha from Koon Annawar Fishing Landing Center, Ayeyarwady Region, Myanmar. The three species Lates calcarifer, Polynemus paradiseus, and Tenualosa Ilisha were negative allometric but only one species Otolithoides pama was positive allometric. The value of ‘b’ ranged from 1.95 to 3.13 and the coefficient of determination ‘r’ values ranged from 0.71 to 0.97. Moreover, the mean condition factor of four commercial fish species was 1.70±2.50 (L. calcarifer), 0.69±2.23 (O. pama), 1.04±1.97 (P. paradiseus), and 1.65±2.20 (T. ilisha), indicating that its growth rate condition has perfected because the value of ‘K’ is greater than 1 so these species suitable for culture interest. Difference of length and weight of four commercial fish species were presented.
