The effect of sexuality on some haematological parameters of the yellowfin seabream, Acanthopagrus latus in Persian Gulf

Acanthopagrus latus is one of the major commercially exploited species in the Persian Gulf. In recent years، it has gained importance as a candidate for aquaculture. Haematological parameters of wild-caught specimens were studied during the pre-spawning period to determine if they are influenced by the sex of fish. Blood samples were collected from 55 Fish (30 female and 25 male) captured from the Musa Creek in the north-west Persian Gulf. RBC counts were higher in male than in female fish (P<0. 05) and other parameters such as WBC، Hct، Hb، MCV، MCH، MCHC and leukocyte differential count did not show a significant difference between male and female fish.
