Mandarin fish domestication method

Abstract

The invention relates to the field of aquaculture and discloses a mandarin dish domestication method. After the mandarin fish fry grow to 6-8 cm when eating live bait, the mandarin fish fry are transferred to a domestication pond with poor light ray. After being on a diet for 2-3 days, the mandarin fish fry are fed with live fish fry and fresh meat products. Feeding amount of the live fish fry is reduced gradually, and artificial feed components are added gradually until the mandarin fish fry are completely not fed with the live bait. The artificial feed comprises 45-50% of protein, 16-20% of fat, 8-10% of carbohydrate, 1-2% of vitamin, 4-6% of mineral, and the balance water. By the scientific domestication method, the obtained mandarin fish is good in convertibility and capable of getting rid of the physical dependence on the live feed. The domestication rate is up to 97.3%, the used artificial feed proportion is capable of meeting the demand of mandarin fish growing, the absorption rate is high, the incidence rate of the mandarin fish is reduced, and therefore compared with the existing feeding cost, the mandarin feeding cost decreases by 68.5%.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for domesticating mandarin fish. Background technique [0002] Mandarin fish, also known as Aohuayu, is a carnivorous, scaly fish; it belongs to the Fataceae fish in taxonomy.

Problems solved by technology

Due to the special feeding habits of mandarin fish, they are absolutely dependent on live feed, which not only causes a large area of ​​death due to bacterial infection, but also causes high cost of breeding due to the use of live feed. In order to reduce the cost of breeding, people domesticate mandarin fish and feed them with artificial feed. The domestication method lacks rationality and scientificity, resulting in the current domestication rate is extremely low, mandarin fish cannibalize each other, and the mortality rate has doubled
