Method for flowing water culturing of grass carp in mountainous area

Abstract

The invention provides a method for flowing water culturing of grass carp in a mountainous area. Natural conditions of the mountainous area are fully used, and dissolved oxygen in water is increased with a natural drop water injection method, running water culturing is guaranteed, so that cultivation of the grass carp is close to natural ecological stocking, and flood, natural enemies and other factors influencing growth of the grass cap are eliminated. The method comprises steps as follows: A, a water tank is dug in a land close to a mountain spring or a stream in the mountainous area and is disinfected, a water inlet and a water outlet are formed in the water tank, mountain spring water or stream water is injected into the water tank from the water inlet of the water tank at a certain height drop through a pipeline, and blocking nets are arranged at the water inlet and the water outlet; B, fries are put into the water tank in the density of 5-8 fries per cubic meter; C, in the growth period of the grass carp, work including three steps is performed, namely, feeding, conditioning of water quality and disease prevention, wherein for conditioning of water quality, impurities in water and blockages on the blocking nets are cleared timely; D, adult fish are caught.

Description

technical field [0001] The invention relates to the technical field of agricultural fish cultivation, in particular to a method for cultivating grass carp in flowing water in a pool in a mountain area. Background technique [0002] Grass carp is one of the four major family carps in freshwater culture in China. It has the characteristics of fast growth, tender meat, delicious taste and rich nutrition, and is deeply loved by people. Grass carp is a typical herbivorous fish, and adult fish mainly eat aquatic plants in a natural state. The favorite species are emperor bamboo grass, aquatic plants, duckweed and so on. Under artificial feeding conditions, they are fed with all kinds of aquatic plants, terrestrial grasses and various concentrated feeds. [0003] In recent years, with the promotion and popularization of aquaculture technology, especially the rapid development of the feed industry, the output of grass carp cultured in ponds has increased year by year. While the ou...

Problems solved by technology

[0003] In recent years, with the promotion and popularization of aquaculture technology, especially the rapid development of the feed industry, the output of grass carp cultured in ponds has increased year by year. While the output of grass carp has increased, it has also caused the outbreak of grass carp diseases, deterioration of water quality, abuse of drugs, The quality is degraded and the breeding benefits are declining, which seriously affects the economic benefits of grass carp farming. How to solve the above problems and how to make the people eat safe fish is a big problem that people generally pay attention to.
