Histological study of WBC and measurement of some blood parameter of spotted catshark Chiloscyllium punctatum in Persian Gulf in the cold season

Measurement of blood parameters is one of diagnosis way for disease and health in marine that can change by numerous factors. In this study 30 spotted catsharks, with similar characteristics of both sexes were caught from the northern estuary, of Persian Gulf. After hunting collection and blood smeer, parameters and factors, including WBC, lymphocytes, monocytes, eosinophils, neutrophils and blood indices, including MCV, MCH, MCHC were measured. Results indicated no significant difference between the measured parameters and both sexes (p>0.05). The parameters, lymphocytes with the highest and eosinophils with lowest number both were seen in males. The amount of white blood cells were more in male than female but the most of blood indices of MCV was seen in male and the lowest of MCHC was seen in female. In this research, WBC blood parameters in cat spotted shark were similarities and differences with other marine that have been reported.
