Comparative study of haematological profile on Gobius niger intwo different habitat sites: Faro Lake and Tyrrhenian Sea

The present study is aimed to assess the influence of different habitats, Faro Lake and Tyrrhenian Sea, on the haematological profile of Gobius niger. For both sites of collection water chemical-physical parameters were measured. Blood samples were taken from 20 fish captured in Faro Lake (group A) and from 20 fish captured in Tyrrhenian Sea (group B) to measure haematological profile that included Red Blood Cell Count (RBC), Hematocrit (Hct), Hemoglobin concentration (Hgb), White Blood Cell Count (WBC), Thrombocyte Count (TC), Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), Mean Corpuscular Haemoglobin Concentration (MCHC), Red cell Distribution Width (RDW), Mean Thrombocyte Volume (MTV), Thrombocyte Distribution Width (TDW) and Thrombocytocrit (Tct). Results showed significantly statistical differences in RBC, Hct, MCH and MCHC between two different locations that are related to variations of the chemical and physical parameters of the water of two different sites of collection. Our findings emphasize the fact that changes in blood characteristics are important indices in monitoring the effects of habitat changes on the physiology of G. niger.
