The grass carp grows fast, the meat is tender and delicious. Grass carp is a typical herbivorous fish, and in a natural state, fish are mainly eaten. The types of favorite food include bitter grass, rotor black algae, duckweed, etc. Under artificial breeding conditions, feed all kinds of like -eating waterweeds, Lu Shenghe undercuts and various se refined feeds. Due to its rapid growth and a wide range of feed sources, it is one of the four fish farming in China. grass carp breeding technology Step/method In environment and pond selection grass carp is the most likely to get sick. Frequent pollution -free grass carp should have a special breeding base and form a certain scale. No pollution source. The breeding base should have sufficient water sources, good water quality, smooth water inlet drainage, different connection between fish ponds, convenient transportation fish transportation, rich feed resources, and good ecological environment. The fish species If want to raise grass carp, you must choose healthy and lively high -quality fish species. It is cultivated without public harm. The quality meets the relevant standards. It has the excellent characteristics of the variety. It is best to have the best self -cultivation of the conditions. The fish species disinfection If fish species must be disinfected before being put in. You can choose chlorine dioxide 20-40 mg / liter per 5-10 minutes, 1 % -3 % of salt every 5-10 minutes. For every 15-30 minutes, 8 mg / liter, potassium permanganate is soaked and disinfected by drugs such as 10-20 mg / liters per 15-20 minutes. The release ratio is put into the fish species according to the 80: 20 release mode, that is, 80 % of the main grass fish, and 20 % of the supporting fish. 4 The scientific bait grass carp mainly feeds water plants in the natural waters. In pond -free farming, it is suitable to use granular feed with scientific ratio to reduce the pollution of water quality for the water quality. Improve the use of bait. It is paired with feeding water and dry grass, feminine, fresh, and pale. Cake meal and other types of bait should be mildew, pollution -free, non -toxic, and treated with crushing, soaking, cooking, etc., and make grass carp for easy bait and easy to digest bait. Feeding bait should adhere to the principles of time, positioning, quality, and quantitative bait, and to determine the reasonable feeding amount through observing weather, water body conditions and fish eating amount. 5 Reasonable feeding fishing drugs Fisher is a substance used to prevent and treat aquatic and plant diseases and insect pests. So use it carefully. Fishing medicines generally include bactericides, insecticides, and water quality modifiers. At present, some traditional fishermen have been disabled, such as chloramphenicol, amurazolidone, sodium pentaol, peacock stone green, sulfonazole, and Tyladine 32 Fishing medicines cannot be used in aquaculture, and special attention should be paid when choosing fishing drugs.

grass carp breeding technology
Step/method
In environment and pond selection
grass carp is the most likely to get sick. Frequent pollution -free grass carp should have a special breeding base and form a certain scale. No pollution source. The breeding base should have sufficient water sources, good water quality, smooth water inlet drainage, different connection between fish ponds, convenient transportation fish transportation, rich feed resources, and good ecological environment.
The fish species
If want to raise grass carp, you must choose healthy and lively high -quality fish species. It is cultivated without public harm. The quality meets the relevant standards. It has the excellent characteristics of the variety. It is best to have the best self -cultivation of the conditions.
The fish species disinfection
If fish species must be disinfected before being put in. You can choose chlorine dioxide 20-40 mg / liter per 5-10 minutes, 1 % -3 % of salt every 5-10 minutes. For every 15-30 minutes, 8 mg / liter, potassium permanganate is soaked and disinfected by drugs such as 10-20 mg / liters per 15-20 minutes. The release ratio is put into the fish species according to the 80: 20 release mode, that is, 80 % of the main grass fish, and 20 % of the supporting fish.

Reasonable feeding fishing drugs
Fisher is a substance used to prevent and treat aquatic and plant diseases and insect pests. So use it carefully. Fishing medicines generally include bactericides, insecticides, and water quality modifiers. At present, some traditional fishermen have been disabled, such as chloramphenicol, amurazolidone, sodium pentaol, peacock stone green, sulfonazole, and Tyladine 32 Fishing medicines cannot be used in aquaculture, and special attention should be paid when choosing fishing drugs.
