Abstract
Monthly total length frequency data of silver sillago Sillago sihama were collected from the coastal waters of Hormozgan Province, Persian Gulf, from July 2011 to July 2012. ELEFAN-I module of FISAT II was used to analyse the length frequency data. The length-weight relationship derived, demonstrated that growth in this species is allometric. The asymptotic length (L∞) was estimated as 26 and 30 cm for males and females, respectively. The growth parameter K was calculated as 0.46 y-1 for males and 0.43 y-1 for females. The total mortality, natural mortality and fishing mortality rates estimated were: 3.55, 1.09 and 2.46 for males and 3.03, 1.00 and 2.03 for females, respectively. The exploitation rate E being more than 0.50, indicates S. sihama stock is currently being overexploited from the Persian Gulf.
