Problems solved by technology

[0003] At present, the pond culture in our country basically follows the structure and layout of the traditional farming method. The breeding mode is outdated and the production efficiency is low. In addition, in the breeding process, due to the frequent occurrence of breeding diseases, the backward feeding mode and the low proportion of fish species Unreasonable and wrong breeding methods have caused a decline in the yield and quality of freshwater fish farming. The meat quality and taste of freshwater fish have been greatly affected, and a large number of diseased and dead fish may be produced. caused major economic losses

Embodiment 1

[0019] A high-yield breeding method for freshwater fish, comprising the following steps:

[0020] 1) Treatment of breeding ponds: Select a breeding pond with a flat bottom, silt depth of 10-15cm, and water depth of 2-2.5m; first drain the water in the breeding pond and expose it to the sun, and sprinkle 150g of quicklime per mu for pond disinfection. Sun for half a month, then inject sterilized lake or river water to a water depth of 1.5-2.5m; add coarse salt to adjust the salinity of the pool water to 0.1-3%; the dissolved oxygen in the pool water is above 6.5mg / L; the ammonia concentration is ≤0.3mg / l ; pH value is 7.5-8.5; water inlet and outlet are set up in the pond, and escape nets are set up at the water inlet and outlet;

[0021] 2) Seed selection and stocking: choose fish fry with neat specifications, strong physique, and no injuries; put 1500 fish fry with a specification of 15-50g / tail per mu; soak the fry in 3-3.5% salt water for 8-10 minutes before stocking ; The...

Abstract

The invention discloses a high-yield freshwater fish farming method, which comprises the steps of culture pond treatment, strain selection and stocking, bait delivery, water quality management and fish disease control, wherein a special synthetic feed is utilized as a bait; the feed can meet the material needs in freshwater fish growth; the immunity of the freshwater fish can be improved through adding traditional Chinese medicinal ingredients; meanwhile, the gastrointestinal function of the freshwater fish is adjusted and the dosage of an antibiotic and an antivirus drug is reduced; meanwhile, the quality of the flesh of the freshwater fish is improved. The immunity of the freshwater is strengthened, so that the morbidity rate is greatly reduced and the growth speed is significantly increased. The added mineral and vitamin can meet the requirements of the freshwater in the growth process, and the growth speed of the freshwater is high.

Description

technical field [0001] The invention relates to the technical field of freshwater fish cultivation, in particular to a high-yield cultivation method for freshwater fish. Background technique [0002] Freshwater fish refers to fish that can live in fresh water with a salinity of three thousandths. Common freshwater fish include crucian carp, bighead carp, carp, grass carp, perch, sturgeon, herring, etc. my country is one of the countries with a large amount of fresh water in the world, most of which are located in the temperate zone or subtropical zone, with a mild climate and abundant rainfall, which is suitable for the growth of freshwater fish. With the development of the economy and the improvement of people's living standards, the market demand for freshwater fish is also increasing. Only by improving the efficiency and quality of freshwater fish farming can freshwater fish farming enterprises and individuals better meet the needs and development of the market. [0003]...
