Asian carp mixed breeding technology capable of increasing utilization rate

Abstract

The invention discloses an Asian carp mixed breeding technology capable of increasing the utilization rate. The technology comprises the steps of pond address selection, fish pond cleaning, sterilization and disinfection, breeding water introduction, fingerling putting, feeding management, water quality management, fish disease control and fishing sales; by means of the disease and pest control means, the survival rate of Asian carp is increased, the bred Asian carp can pass strict medicine residue detection, secondary disinfection is conducted on a pond by means of tea cakes, and part of teacake residues are left for serving as nourishment fertilizing the water quality; before fingerling putting is conducted, fishes are soaked with a saline solution so as to kill germs and parasites which parasitize the fishes; multiple aerators are additionally arranged, the problem that due to oxygen deficit, mandarin fishes are low in survival rate, and then the yield is low is solved, and the yield and the economic benefit of the mandarin fish pond are greatly increased.

Description

technical field [0001] The invention relates to a culture technology, in particular to a mixed culture technology of four major domestic carps which can improve the utilization rate. Background technique [0002] Before the Tang Dynasty, carp was the most widely farmed freshwater fish. However, because the surname of the Tang royal family was Li, the breeding, fishing and selling of carp were prohibited. Fishermen had to engage in the production of other species, which resulted in the four major carp, herring, grass carp, silver carp and bighead carp. [0003] Herring, also known as black carp, has large scales all over its body. The appearance is very similar to grass carp, but the scales and fins all over the body are grayish black. The name of herring also comes from this. The scales of herring are large and thick. Its tail is thinner and longer than that of grass carp. The dorsal fin, pectoral fin, pelvic fin and caudal fin are longer and stiffer than grass carp. Herr...

Problems solved by technology

[0005] The technical problem to be solved in the present invention is to overcome the low efficiency of the existing domestic fish cultivation method and the defects of low cultivation yield, to provide a mixed cultivation technology of the four major domestic fishes that can improve the utilization rate, and to use the means of disease and insect control to improve the production efficiency of the domestic fish. The survival rate of fish, farmed domestic fish can pass the strict drug residue test, and use tea dead to carry out secondary disinfection on the pond, leaving some tea dead cake residue as nutrients for fertile water quality; before putting fish species, use salt Soak the fish body in water to kill the bacteria and parasites that live on the fish body; add multiple aerators to solve the problem of low survival rate and low yield of mandarin fish due to lack of oxygen, and greatly improve the production of mandarin fish Pond production and economic benefits, thus solving the above problems
