Comparative study of two carnivorous fish (Parupeneus forsskali and Thalassoma klunzingeri) from the Red Sea: Hemato-biochemical parameters and cellular characterization

Although, the Red sea is highly rich with fish fauna but still the information known is so limited for the researchers especially about the fish physiology baselines. So, in the present study we investigated the heamto-biochemical parameters and cell characterization of two fish having the same feeding habitats. Fish specimens of Red Sea goatfish (Parupeneus forsskali) and Klunzinger's wrasse (Thalassoma klunzingeri) were captured from Hurghada, Egypt. Haematological and biochemical analysis as well as blood cells characterization were performed. The morphological and cytochemical aspects of peripheral blood cells of the two species were studied by light microscopy. Thalassoma klunzingeri showed lower Hct and Hb values and RBCs count. Fusiform to spindle shape thrombocytes were found only in the blood of Parupeneus forsskali while spiked thrombocytes were found only in the blood of Thalassoma klunzingeri. This investigation may be helpful as a tool to monitor the health status of the two species and will be used as biomarkers for clinical pathology.
