dc.description.abstractThe long nose trevally, Carangoides chrysophrys is one of important commercial species of family carangidae in the Persian Gulf and Oman Sea .population dynamic parameters, reproductive biology and feeding habits of this species were studied from April 2016 to march 2017 in the Coastal Waters of Hormuzgan province. Length frequency analysis of 440 specimens of C.chrysophrys with total length (TL) ranged from 250 to 800 mm were shown isometric growth. Growth parameters including K, L and t0 were calculated 0.390 (1/year), 66.86 Cm and 0.029 Year respectively. The instantaneous rate of total mortality (Z), natural mortality (M) and fishing mortality (F) were estimated 1.21, 0.761 and 0.449 (1/year) respectively. Exploitation rate was 0.4 per year indicated that fishing effort on this species is in a moderate condition. Reproductive studies showed that C.chrysophrys has long spawning period with two peaks in spring and autumn respectively. Females reached 50% sexual maturity at 38.4 cm. Stomach content analysis of this species revealed that bony fishes (% 77) formed main food and followed by crustacean (% 18) and molluscs (% 5) as random food.en_US
