Effects of Temperature on the Growth Performance, Biochemical Indexes and Growth and Development-Related Genes Expression of Juvenile Hybrid Sturgeon (Acipenser baerii♀ × Acipenser schrenckii♂)

In order to investigate the effects of temperature on growth performance, biochemical indexes and genes expression in juvenile hybrid sturgeon (Acipenser baerii♀ × Acipenser schrenckii♂), five treatment groups (18 °C, 21 24 27 30 °C) were set this study. After 25 days domestication, specific rate (SGR) relative weight gain increased at first then decreased with increase range 18–30 °C reached highest value °C. A quadratic equation was used fit regression SGR (T). The result showed that maximum is 23.45 Moreover, level hormone (gh) content blood glucose (GLU) significantly while receptor (ghr) liver significantly. When exceeded thyroid levels affected, total antioxidants (T-AOC) reduced glutathione (GSH) higher than those control group. addition, temperature, hsp70 hsp90 significantly, luteinizing (lh) brain To summarize, effect development mainly occurs through metabolism, level, antioxidant capacity growth-related genes. Therefore, a between can obtain survival rate.
