Sex differences of hematological and biochemical parameters in healthy rainbow trout (Salmo gairdneri, R)

Abstract

A hematological study of the rainbow trout has permitted to establish a sexual difference in the parameters related to it, such as haemoglobin, haematocrit, erythrocyte and leukocyte count.The types of leukocytes were homologated to the human blood.Haemoglobin, haematocrit, erythrocyte sedimentation rate, erythrocyte and leukocyte count values were lower in female than male.The normal values of some biochemistry parameters were equally studied and in some cases they similarly showed a sexual difference.Creatinine, triglycerides, phosphatase alkaline, sodium and globulin values were higher in female than male.Establishing a sexual difference from the biochemical and hematological parameters is possible.
