Resumo: |
The objective of this work was to determine hematological parameters and the phagocytic capacity of peritoneal macrophages of the fat snook related to sex, stage of gonadal maturation and seasonal cycle. The hematological results did not show significant differences between males and females. With respect to stage of gonadal maturation, only erythrocytes numbers (RBC), in females, was found to be significantly elevated in stage III (maturing) and decreased in V (spent). An analysis of the results of the erythrocyte and leukocyte series, thrombocytes and phagocytic activity related to sex and seasonal cycle showed statistically significant differences: a) in males, hematocrit (Ht) and hemoglobin concentration (Hb) were elevated in the spring and low in the winter; b) in both sexes, mean corpuscular volume (MCV) was high in the spring and summer and low in the fall; c) in females, thrombocytes numbers were elevated in the fall and low in the other seasons; d) in both sexes, phagocytic capacity (PC) and phagocytic index (PI) were higher in the summer and lower in the fall. The results showed that spring and summer correspond to seasons of the year for better hematological and phagocytic responses for survival of the fat snook in its natural habitat. The parameters studied could be utilized for evaluation of the health status in its own habitat or in captivity. |
