The purpose of this research is to see how sex affects several haematological, biochemical and blood cell morphology in cultured brown trout, Salmo trutta fario. Different haematological parameters, for instance haemoglobin (Hb) concentration, haematocrit (Hct), red blood cell (RBC) and white blood cell (WBC) counts, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) and serum biochemical parameters such as glucose, cholesterol, total protein, albumin, globulin, alanine aminotransferase (ALT), alkaline phosphatase (ALP), aspartate aminotransferase (AST), sodium, potassium and phosphorus were analysed. Throughout the study period, male fish had considerably greater Hb content, RBC count and Hct content than female fish, but insignificant (P > 0.05) difference in WBC count, differential leucocyte count, MCV, MCH and MCHC was seen between the two sexes of Salmo trutta fario. The majority of biochemical markers showed no significant (P > 0.05) difference, with the exception of AST, ALP, sodium, potassium, and phosphorus, which showed a significant (P < 0.05) difference. Under light microscopy, RBC and differential leukocyte count (neutrophils, lymphocytes, and monocytes) as well as thrombocytes were characterised and discriminated, revealing that the majority of the cells were normal and intact in shape. As a result of the foregoing findings, it is suggested that the data generated be used to identify the health state of fish and to determine the occurrence of various clinical and subclinical disorders, which might assist in enhancing the overall fish population production.
