Abstract

SCOMBERMORUS COMMERSONis is one of the most important large pelagic fish species in HORMOZGAN PROVINCE. Nominal catch of S.commerson in 2007 was 5912 tonnes or 13% of total catch of large pelagic fishes. There was need to identify FISHING PATTERN, MAXIMUM CONSTANT YIELD and RECRUITMENT PATTERN in order to exploitation of sustainable from stocks of S.commerson. So length and weight data were collected randomly from 3 major commercial fish-landing sites; Bandar Lengeh, Bandar Abbas and Bandar Jask in HORMOZGAN PROVINCE, 12 months from the beginning of April 2007. Growth parameters K and L∞ estimated 0.66 (1/year) and 150.24 cm respectively, so natural mortality calculated 0.67 (1/year) and therefore MAXIMUM CONSTANT YIELD computed 1490 tonnes. Length-weight power relationship, W=aFLb, was W=1.86E-02FL2.87 that showed S.commerson have isometric growth. FISHING PATTERN indicated that almost 50% of catch were under the size at first maturity. Maximum of RECRUITMENT PATTERN was in Mehr (October) with average fork length of 40 cm. For optimum exploitation from S.commerson stocks, two approaches are: Fishing forbidden in maximum recruitment time and gear (drift gillnet) modification.
