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 the growth performance, biochemical indexes and genes expression in juvenile hybrid sturgeon ( Acipenser baerii ♀ × Acipenser schrenckii ♂), five temperature treatment groups (18 °C, 21 °C, 24 °C, 27 °C, 30 °C) were set in this study. After 25 da...

A quadratic equation was used to fit the regression equation of SGR and temperature (T). The result showed that the temperature of the maximum SGR is 23.45 °C. Moreover, the expression level of the growth hormone ( gh ) and the content of blood glucose (GLU) increased significantly at 21 °C, while the expression level of the growth hormone receptor ( ghr ) in the liver decreased significantly.
