Problems solved by technology

In addition to breathing with the gills, you can also breathe with the skin and intestines. However, although the breeding environment for loach is not strict, it requires a relatively large breeding area, which will increase the difficulty of breeding for farmers and increase the labor intensity. natural increase

Abstract

The invention discloses a technical method for cultivating loach by adopting a net cage, and relates to the technical field of aquiculture. The technical method comprises the following steps: the selection of a water body, the arrangement of a net cage, the breeding of loach seeds, the feeding of fodder, the management of water quality, the prevention of diseases, and the timely capturing. The technical method has the benefits that the production resources are fully utilized, the cultivation pollution is avoided, the cultivation technology is standard and specified, the feeding is scientific and specified, the technology is novel, the quality of the aquiculture is improved to a large extent, and the labor of farmers is alleviated, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a technical method for cultivating loach in a cage. Background technique [0002] Loach is a fish belonging to Cyprinidae, Loachidae, and Loach, and belongs to small economic fish. Loach has high economic value, tender, light and delicious meat, and has nourishing and medicinal value, so it has always been loved by people. It is widely sold in Korea and Japan. Loach is not only nutritious and delicious, but also has a variety of medicinal effects, so it is called "ginseng in water". Loved by the majority of consumers, the demand in domestic and foreign markets is large, and the export volume has increased year after year. The meat contains 18.4%-20.7% protein, 2.7%-2.8% fat, 1.6%-2.2% ash, and every 100 grams of fish meat contains vitamin A70 international units, vitamin B130 micrograms, vitamin B2440 micrograms, calcium 51 mg, phosphorus 154 mg , 3 mg of iron, and contai...
