Pond fish culturing technology

Abstract

The invention discloses a pond fish culturing technology. A method includes the following steps that a pond is cleaned, water is discharged, after the pond is cleaned, the pond is exposed to the sun till the bottom of the pond cracks, quicklime is used for disinfecting the bottom of the pond, the water discharging depth is 1.3 m, high-quality fry are selected for well completing the inspection and quarantine work in the fry throwing process, according to the throwing density and proportion of the fry, 400 grass carps are thrown per mu, each grass carp weighs 50-150 g, 10 silver carps are thrown per mu, each silver carp weighs 50-250 g, 300 golden carps are thrown per mu, each golden carp weighs 50-100 g, 100 common carps are thrown per mu, and each common carp weighs 50-100 g, water quality and water level control is conducted in daily management, fodder is used for feeding, taking the grass carps and the silver carps as an example, ryegrass is taken as the main fodder for the grass carps and the silver carps, disease prevention is conducted, powder chlorine dioxide is used for disinfecting and sterilizing, three times of insect killing is appropriate all the year round, trichlorfon and copper sulfate are generally used for insect killing, and catching and stocking are conducted in rotation. According to the method, the yield and the quality of polyculture fishes can be effectively improved, the diseases are reduced, and the culture benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a fish farming technology in a pond. Background technique [0002] Pond fish farming is a fish farming method used in most areas of China. The current output accounts for more than 70% of freshwater fish farming. It has the characteristics of small investment, large returns, quick results, and stable production. [0003] Pond farming in my country has a history of more than 2,000 years, and there was a record of pond fish farming as early as the 11th century BC. The "Fish Culture Classic" written in the 5th century BC is the earliest work on fish farming in the world. Carp farming was very common in the Han Dynasty. In the Tang Dynasty, carp culture developed from single carp culture to mixed culture of grass carp, herring, silver carp, bighead carp and other fish. An important breakthrough in pond fish farming technology; by the Song Dynasty, it was quite develo...

Problems solved by technology

[0005] However, there are also a series of problems in the pond aquaculture industry, which seriously hinder the sustainable and healthy development of the pond aquaculture industry.

Its main performance is that the standard of basic conditions for breeding production is low, the proportion of mixed breeding is unscientific, the problem of breeding pollution is serious, the problem of breeding disease is serious, and the economic benefit of breeding is low.
