Abstract: (551 Views) |
This study was conducted to determine the biological indices of Acanthopagrus arabicus in the northern waters of the Oman sea- Sistan and Baluchistan province during the years 1399 to 1400 and the feeding habits of 267 species of Acanthopagrus arabicus were studied. The result of feeding indices of Acanthopagrus arabicus showed that crustacean, mollusks and fish of the fish are the diettray priorities of this species, respectively. Examination of GaSI Gastric index in this fish showed that the intensity of feeding is high in spring and then autumn and reaches its minimum in summer and winter. The highest index of empty stomach CV in this fish is in spring and showed that this species is very sparse and anorexic in this season, which is the season of reproduction and is relatively over eating in autumn specially in winter, because in winter, this index has an upward trend from spring to autumn and decreases from autumn so that it reaches its lowest value in winter. Give the lowest value of this index in spring and from summer the amount of this index in spring and from summer the amount of this index increases which reaches the highest value in winter. In fact, the breeding season of this species in winter.
