Comparison of Blood Parameters and some Biochemical Factors and Blood Serum Enzyme Rainbow Trout Fed with Manual and Commercial (Pellet) Food Diet

Inroduction & One way to evaluate the physiological characteristics of the fish to determine the blood that is superior to other methods, easier and less costly. In this study, determination and comparison of some blood factors rainbow trout fed with manual and commercial (pellet) food diet was done.
Testing for 8 weeks in both groups, with a total of 60 fish from each group were done. Blood samples were collected from the fish using the caudal vein cut and each blood parameters in hematology laboratory values were measured.
: the results of this study showed that blood on the white blood cells, red blood cells, hemoglobin, hematocrit trout fed commercial diets and manual significant difference(P 0.05) and the mean corpuscular volume, corpuscular hemoglobin, neutrophils, lymphocytes and eosinophils, there is no difference(P> 0.05). The results showed that blood biochemical parameters of glucose, cholesterol, triglycerides, creatinine, phosphorus, chloride, iron and albumin significantly different(P 0.05), but the amount of calcium, potassium, sodium, urea and total protein no there is no significant difference(P> 0.05). Also, in terms of Spar aminotransferase and alanine aminotransferase significant difference between the two groups(P 0.05).
The results of this study suggest that the type of diet can affect blood indices fish.
