Method for culturing whitefish through running water

Abstract

A method for breeding white fish in running water, which relates to the technical field of fish farming, comprising the following steps: constructing fish ponds, constructing fish ponds in rows and in steps, and building them with cement, and the water surface area of ​​a single fish pond is 10 to 200 square meters The depth of the water is between 1.5 and 2 meters. There are water hole grooves between the adjacent single fish ponds for continuous disinfection. The disinfection kits are wrapped with gauze and bound to the edge of the most upstream single fish pond; white fish Stocking, raising 8 to 12 seedlings per unit square; daily management: replenish water to the most upstream fish ponds every day, and the water in the upstream fish ponds flows downstream continuously to ensure the water flow rate of each fish pond , every 15 to 20 days to clean up the silt at the bottom of the pond to ensure that the thickness of the bottom silt is less than 10cm. The invention has good water flow conditions and high oxygen-enriched content, is convenient for rapid growth of white fish, and has high quality of white fish.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a method for cultivating white fish in running water. Background technique [0002] There are 16 species of white fish, which are endemic to our country. It is mainly distributed in the northwest of Yunnan and Qionghai in Sichuan. The areas where these fishes are distributed are often relatively narrow, and often one species is only found in one lake or one reservoir. It is Qiao Yu, which grows in rivers and lakes. It is white in color, with a happy head, and the big ones are six or seven feet long. It tastes beautiful. The back of the body is slightly blue-gray, the sides are silver-white, and the fins are gray-black. It usually lives in the middle and upper layers of flowing water and large water bodies. It swims quickly and is good at jumping. It feeds on small fish. It is a ferocious fish, and less Growing in small rivers or ponds, the method of breeding whitefish i...

Problems solved by technology

The back of the body is slightly blue-gray, the sides are silver-white, and the fins are gray-black. It usually lives in the middle and upper layers of flowing water and large water bodies. It swims quickly and is good at jumping. It feeds on small fish. It is a ferocious fish, and less Growing in small rivers or ponds, the method of breeding whitefish in the prior art is not much different from other fish. Generally, it is cultivated in a single fish pond, which is quite different from the wild environment of whitefish. , the low oxygen content in fish ponds leads to relatively slow growth of white fish, and the meat quality of white fish is relatively soft and poor in quality. good for whitefish growth
