Abstract:   (77 Views)
The population parameters of Malabar trevally (Carangoides malabaricus) were studied in the Persian Gulf and Oman Sea from December 2016 to November 2017. 1030 specimens were collected. The fork length ranged from 14 to 34 cm, with average 25.60±3.52 cm. The total weight ranged from 60.4 to 534.5 g, with average 329.03±113.46 g. The asymptotic length (L∞) and growth coefficient (K) were 37 cm and K=0.85 per year, respectively. The probability of capture was calculated in fork length as L25%=22.47 cm, L50%=24.02 cm and L75%=25.26 cm. The length-weight relationship was determined as W= 0.06 L 2.62. The annual total mortality (Z), fishing mortality (F), and natural mortality (M) coefficients were estimated 3.1, 1.62, and 1.48 per year, respectively. The current rate of exploitation (E) was 0.52, and the value of exploitation ratio was found reasonable for current fishing effort. The results indicated that the Malabar trevally stock was not overexploited.
