Study on some population dynamics parameters of Sardinella sindensis (Day, 1878) in Coastal waters of Jask Province

Sind sardine Sardinella sindensis (Day, 1878) is the most important ecological and commercial surface resources in Persian Gulf and Oman sea. This study was carried to study some population dynamics parameters of Sind sardine in Coastal waters of Jask Province during January 2011 to December 2012. A totall 2887 specimens were collected from commercial fishing Purse seiners, monthly. Biometric parameters were measured. The mean length and weight were 14 cm, 29 g respectively and the most dominated length group was 14-15 cm (24.7%). The Von Bertalanffy growth parameters were calculated as L=19.5 (cm), k=1.18 (year-1), t0 = -0.18. Weight- length relationship showed an isometric growth and it was W = aL3.0522 (r2= 0.9432). The natural (M), fishing (F) and total (Z) mortality were 2.19, 0.87 and 3.06 per year respectively. The exploitation rate (E) was 0.29.
