This study aimed at determining blood biochemical parameters with potential diagnostic value to assess the nutritional status for healthy Snow trout, Schizothorax zarudnyi. For this purpose, three treatment groups of Snow trout (average weight, 65.9±5.3 g) were kept unfed for 24 h, 7 and 14 days. During the experiment, a natural photoperiod was adopted, water temperature was maintained at 23.2±...

Nowadays, the entrance of pollutants including heavy metals in environment threatens the life of aquatic animals. In this study, the effect of zinc chloride (6 mg/l) and cadmium chloride (5 mg/l) exposure were studied on the activity of some metabolic enzymes in the liver, gills, brain and muscle in Snow trout (Schizothorax zarudnyi). The results showed that zinc caused a significant increase i...
