C, change water management, according to the situation such as water temperature, breeding density, the exchange capacity of water controls at 1-3 time per hour;

D, feed and throw something and feed, nutrition of throwing something and feeding is thick protein > 40%-45%, crude fat 5%-9%, raw fiber 3%-5%, coarse ash 10%-16%, moisture 8%-12%, the feed of lysine > 2.0%.

Further, described disinfectant is chlorine dioxide.

Further, the concentration of described chlorine dioxide is 2PPM.

Further, in order to prevent and treat furunculosis, also having Florfenicol in the feed of described feed and step of throwing something and feeding, being used in conjunction 5d.

Further, the addition of described Florfenicol is the 200mg/kg by fish body weight.

Further, in order to prevent and treat enteritis disease, also have allicin powder in the feed of described feed and step of throwing something and feeding, throw something and feed 4d ~ 6d continuously.

Further, the addition of described allicin powder is the 200mg/kg by fish body weight.

Further, in order to prevent and treat ich, this cultural method is also included in full pond and sprays melonworm spirit, every day 1 time, continuous 2 ~ 3d.

Further, the concentration of described melonworm spirit is 5ppm.

Further, reasonable disposition is reached in order to make the nutrition of fingerling and adult fish, be beneficial to sturgeon to digest and assimilate in different phase, growth promoting effects, described feed and step of throwing something and feeding are divided into fingerling stage and adult fish stage, the fingerling stage selects nutrition to be thick protein > 42%-45%, crude fat 5%-9%, raw fiber 3%-5%, coarse ash 10%-16%, moisture 8%-12%, the feed of lysine > 2.0%, the adult fish stage selects nutrition to be thick protein > 40%-42%, crude fat 5%-9%, raw fiber 3%-5%, coarse ash 10%-16%, moisture 8%-12%, the feed of lysine > 2.0%.

Beneficial effect of the present invention is: by cultivating the sterilization in front convection current pond, and the extermination of disease and insect pest in forage feed, substantially increase the survival rate of sturgeon fingerling, by configuring the feed of fingerling and adult fish Different Nutrition composition, be beneficial to sturgeon to digest and assimilate in different phase, growth promoting effects.
