Biochemical and hematological parameters in European sea bass (Dicentrarchus labrax Linnaeus, 1758) and Gilthead sea bream (Sparus aurata Linnaeus, 1758) in relation to temperature

In order to evaluate the influence of temperature on biochemical and hematological parameters in two different farmed fish, the gilthead sea bream (Sparus aurata Linnaeus, 1758) and the European sea bass (Dicentrarchus labrax, Linnaeus, 1758), blood samples were collected from a total of 60 specimens of each species, reared in Sicily, in the cold (February, mean temperature 13.40 °C) and warm seasons (October, mean temperature 23.20 °C). Biochemical (glucose, lactate, cholesterol, triglycerides and total protein) and hematological (red blood cell RBC, hemoglobin concentration Hgb, hematoctit Hct, mean corpuscular volume MCV, mean corpuscular hemoglobin MCH and mean corpuscular hemoglobin concentration MCHC) parameters were evaluated. Significant differences (P<0.05) were observed for glucose, lactate, triglycerides, cholesterol, total protein and RBC, Hgb, Hct, MCV, and MCH. This information could be useful for optimization of the husbandry practices in land-based aquaculture, and provide useful information for monitoring changes in the health status of fish.
