Problems solved by technology

[0004] Reservoir cage culture, because the water body is relatively open and smooth, the disease is difficult to prevent and control, and the breeding effect is not ideal. However, the incidence of diseases in the culture of black-ridged barb is increasing year by year. The quality and safety of the hidden dangers

Abstract

The invention belongs to the field of fish culture, and particularly relates to a healthy and efficient culturing method for freshwater fish. The method comprises the following steps: pond dredging, pond disinfection, application of fertilized water to the pond, and connection of the water discharging port of the pond to a nearest farmland impounding reservoir or intake canal; placement of 1500-1800 main cultivated fish with the respective full length of 5 cm or above in every 666.67 m<2> of the pond, and placement of mixed cultivated silver carps, bighead carps and crucians; feeding with a puffed granule mixed feed accounting for 2-6% of the total weight of the fish in the pond every day, and feeding with a green feed as an auxiliary feed, wherein the mixed feed and the green feed are added twice a day; keeping of the water running for 24 hours a day; changing of the water 2 or 3 times a month; spreading of quicklime after the water changing, wherein spreading all over the pool is carried out 1 or 2 times a month, and 10-30 g of the quicklime is applied to 1 m<3> of the water; and culturing for 16-20 months. The method can improve the survival rate and the yield of the freshwaterfish, and realizes energy conservation, environmental protection, quality improvement and efficiency improvement in culture production.

Description

technical field [0001] The invention relates to a healthy and efficient breeding method for freshwater fish, which belongs to the field of fish breeding. Background technique [0002] At present, the main breeding methods of freshwater fish in my country are pond culture, cage culture, and factory culture, which generally have shortcomings in the function of the breeding ecosystem. In recent years, the resulting breeding environment has weak self-purification ability and resources (bait, water) A series of problems such as low utilization rate, easy occurrence of diseases, product quality decline, unstable yield and benefit, and impact on the surrounding environment have become increasingly prominent, which have seriously restricted the development of the industry itself. [0003] Freshwater fish such as black barb barb, also known as light barb barb, spiny barb, commonly known as light fish, military fish, etc., are mainly distributed in the Qiantang River, Minjiang River, P...
