Abstract

The invention discloses a cultivation method for Chinese bostrichthys sinensis. The bottom of a pond is an inclined plane, soil with the thickness of 10 to 20cm is laid on the bottom of the pond; the wall and the bottom of the pond are constructed by hard materials; the salinity of the pond water is 1 to 28 per thousand and the temperature thereof is 15 to 25 DEG C; a perch shelter is placed on the bottom of the pond; the pond is sterilized before stocking fish fry; and the fish fry is sterilized before stocking; the stocking density is 5000 to 8000 fishes per mou; living feed and / or compound feed is used for feeding, which is thrown into the pond twice a day, with the daily throwing amount of 9 to 15 percent of the body weight of fish; By using the method of the invention, the survival rate can be improved, the feed period can be shortened and economic benefits can be improved.

Description

technical field [0001] The invention relates to aquaculture technology, in particular to a method for cultivating Chinese snakeheads. Background technique [0002] Chinese snakeheads belong to the family Channaidae. Channa sinensis is rich in nutrients, delicious in meat, and has the effect of speeding up the healing of wounds. In addition, the biggest feature of this fish is that it can stay out of water for a week in damp conditions. A good seafood variety for export earning foreign exchange. [0003] Chinese snakehead is a warm-water shallow sea brackish water fish. It is mainly distributed in estuaries and harbors, and lives in mud holes or caves. Small in size, carnivorous, likes to eat small miscellaneous crabs, shrimps, fish, shellfish, etc. The optimum water temperature is 23-26°C. When the water temperature is lower than 15°C, they are generally in caves and do not go out for food. The lethal water temperature is below 10°C. The appropriate pH value is 7.0-8.2,...
