Investigation on growth and mortality of Escualosa thoracata reported in the present literature is based on the length frequency data collected from April 2013 to March 2014. Asymptotic length (L∞), growth coefficient (K) and t0 were estimated as 119.6 mm, 1.85 year-1 and -0.000095 year respectively. VBGF plot indicated that the fish reaches 72.17 and 100.79 mm at the end of 6 and 12 months respectively. The phi- prime value was obtained as 2.423. Total, natural and fishing mortality coefficient was estimated as 7.809 year-1, 3.45 year-1 and 4.35 year-1 respectively. The exploitation rate (U) and exploitation ratio (E) were estimated as 0.556 and 0.557 yearr-1 respectively. Not Available |
