How different rearing temperatures affect growth and stress status of Siberian sturgeon Acipenser baerii larvae
Abstract Environmental temperature is one of the critical factors affecting fish development. The aim of this study was to examine the impact of three different rearing temperatures (16, 19 and 22°C) throughout the endogenous feeding phase of the Siberian sturgeon Acipenser baerii . This was perform...
