evaluation of some blood serum biochemical parameters of rainbow trout (oncorhynchus mykiss) cultured in earthen ponds

in order to determine of some blood serum biochemical parameters in rainbow trout blood samples were taken from the caudal vein of 531 apparently healthy rainbow trout cultured in earthen ponds. data was analyzes by regression analysis pearson correlation coefficient test and fisher's test. the mean values of alp ast alt and ldh were 722±320 337±150 29±24 and 579±353 u/l and the mean values of sodium potassium and chloride were 144.4±6.8 1.8±0.5 and 126.7±13.0 mmol/l respectively. the mean values of total protein and albumin were 4.0± 0.7 and 1.7±0.8 gr/dl. in this study the mean values of uric acid creatinine urea triglyceride cholesterol glucose calcium and phosphorus were 1.7±0.6 0.4±0.2 9.1±4.8 273.4±165.2 270±88 103.8±35.9 15.9± 2.9 and 25.3±5.0 mg/dl respectively. the results of regrisson analysis showed that with increase in age the mean values of albumin total protein cholesterol sodium potassium and chloride increased and the mean values of triglyceride creatinin ast alt and ldh decreased (p
