Abstract

The invention discloses a high-yield pollution-free breeding method of freshwater fish. The method includes the following steps that requirements for a breeding pond are met; the pond is filled with water, and water quality is adjusted; fish varieties are selected; fish varieties are sterilized; reasonable fish stocking is performed; fish varieties are bred; the water quality is controlled; after water is added into the pond every time, a certain amount of special fertilizer for aquaculture and saccharomycete are added into the breeding pond, and moderate fishing is performed. According to the method, due to sterilization and scientific breeding of the fish pond and the fish bodies, the using amount of medicine and artificial feed is effectively reduced, and the bred freshwater fishes are high in quality safety and free of pollution; due to the mixing breeding of the fish varieties living in different depths of water areas, the fishes are diversified in variety, space of the fish pond in different depths of water areas is effectively utilized, and not only is breeding number improved but also income of fishermen is increased due to orderly fishing according to batches.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high-yield and pollution-free breeding method for freshwater fish. Background technique [0002] Freshwater fish refers to fish living in fresh water, with a wide variety, 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. However, on the one hand, fishermen only pay attention to the quantity and ignore the quality of fish, and on the other hand, they lack scientific and professional farming techniques, resulting in low quality of freshwater fish and a d...
