Stress and hematological responses of juveniles beluga sturgeon (Huso huso L.) held in low or high densities in winter condition after applying anesthesia
This study was performed in order to evaluate the effects of chronic stress (density) and acute stress (handling) existed in culture environments on stress and hematological parameters of beluga sturgeon (Huso huso) under winter condition (below 10°C) after application of anesthesia. Fish with mean...
