Physiological and morphological response to short-term starvation and re-feeding in sub-yearling siberian sturgeon (Acipenser baerii Brandt, 1896): effects of compensatory growth
In this study, the capacity of Siberian sturgeon, Acipenser baerii with mean weight 19.3±0.4 g to face short-term starvation and subsequent re-feeding was assessed for a 40-day period. To investigate, the effect of compensatory growth on some physiological response (plasma cortisol, thyroid hormones...
