Problems solved by technology

[0003] At present, there are very few species of artificially cultured freshwater fish, which not only cannot meet the needs of people in various aspects of purchase and nutrition, but also is not conducive to maintaining the ecological environment in fish ponds. The production of fish will be greatly reduced, and there is still the phenomenon of abuse of antibiotics and other drugs, which cannot meet the environmental protection requirements of freshwater fish and endanger people's health

Embodiment 1

[0028] A high-yield freshwater fish culture method, comprising the steps of:

[0029] (1) Cleaning and disinfection of breeding ponds: Choose a pond that is far from pollution and convenient for drainage and irrigation. Drain the pond water 15-18 days before stocking, remove the silt at the bottom of the pond, keep the silt at 20-25cm, and expose to the sun continuously for 4- After 6 days, after drying until cracked, remove the debris at the bottom of the pond, and evenly spray 320kg of 0.6g / mL quicklime water and 65kg of 0.4g / mL ammonia water per mu for disinfection.

[0030] (2) Preparation before stocking: After the pond is disinfected for 6-8 days, use a 40-60 mesh sieve to filter the incoming water to prevent wild fish from entering the pond, fill it with water to a depth of 1.2-1.3m, and stack it on the sunny side of the pond for fermentation The mixed organic fertilizer of decomposed pig manure, cow manure, chicken manure and rabbit manure is used to cultivate plankton...

[0039] A high-yield freshwater fish culture method, comprising the steps of:

[0040] (1) Cleaning and disinfection of breeding ponds: Choose a pond that is far from pollution and convenient for drainage and irrigation. Drain the pond water 15-18 days before stocking, remove the silt at the bottom of the pond, keep the silt at 20-25cm, and expose to the sun continuously for 4- After 6 days, after drying until cracked, remove the sundries at the bottom of the pond, and evenly spray 300kg of 0.8g / mL quicklime water and 55kg of 0.4g / mL ammonia water per mu for disinfection.

[0041] (2) Preparation before stocking: After the pond is disinfected for 6-8 days, use a 40-60 mesh sieve to filter the incoming water to prevent wild fish from entering the pond, fill it with water to a depth of 1.2-1.3m, and stack it on the sunny side of the pond for fermentation The mixed organic fertilizer of decomposed pig manure, cow manure, chicken manure and rabbit manure is used to cultivate plankt...

Embodiment 3

[0050] A high-yield freshwater fish culture method, comprising the steps of:

[0051] (1) Cleaning and disinfection of breeding ponds: Choose a pond that is far from pollution and convenient for drainage and irrigation. Drain the pond water 15-18 days before stocking, remove the silt at the bottom of the pond, keep the silt at 20-25cm, and expose to the sun continuously for 4- After 6 days, after drying until cracked, remove the debris at the bottom of the pond, and evenly spray 352kg of 0.7g / mL quicklime water and 78kg of 0.4g / mL ammonia water per mu for disinfection.

[0052] (2) Preparation before stocking: After the pond is disinfected for 6-8 days, use a 40-60 mesh sieve to filter the incoming water to prevent wild fish from entering the pond, fill it with water to a depth of 1.2-1.3m, and stack it on the sunny side of the pond for fermentation The mixed organic fertilizer of decomposed pig manure, cow manure, chicken manure and rabbit manure is used to cultivate plankton...

Abstract

The invention discloses a high-yield freshwater fish culture method. The culture method comprises the steps of pond cleaning and disinfection of a culture pond, preparation before fish stocking, fry prelibation, fry stocking, feeding, pest control and prevention, water quality control and humidity fishing. According to the high-yield freshwater fish culture method, through the reasonable disinfection of the culture pond and the reasonable fertilization and water injection before fish stocking, the method provides an ecological environment with a safe and stable earlier stage for fry, so that the culture method is green and environmental protection, the intensification is higher, the fish production is greatly increased, the fish with different feeding habits is fed with the collocation of plankton and fodder without antibiotic, the pollution is less, the safety is high, and through the pest management, the water quality management and the modest fishing, the healthy growth and the delicious meat quality of the freshwater fish can be guaranteed effectively.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high-yield freshwater fish cultivation method. Background technique [0002] Freshwater fish refers to fish that can live in fresh water with a salinity of three thousandths. There are many types, accounting for about 40% of the total fish. Most of my country is located in the temperate zone and subtropical zone, with a mild climate and abundant rainfall. It is a big country for freshwater fish farming. In recent years, with the rapid development of my country's economy and the improvement of people's living standards, the demand for fish has increased year by year, which has prompted an intensive development trend in aquaculture, especially freshwater fish farming. [0003] At present, there are very few species of artificially cultured freshwater fish, which not only cannot meet the needs of people in various aspects of purchase and nutrition, but also is not conducive t...
