Ecological breeding method of breeding penaeus vannamei boone, crucian and chub in mixed mode

Abstract

The invention discloses an ecological breeding method of breeding penaeus vannamei boone, crucian and chub in a mixed mode. The method includes the steps of preparing a pond, cleaning the pond, inputting water, disinfecting the pond water and richening the water sequentially before throwing in fingerlings and shrimp larvae, throwing in white gold crucian and chub, and then throwing in penaeus vannamei boone larvae. Compared with the prior art, the method has the advantages that the thrown-in white gold crucian does not rob food from the penaeus vannamei boone, the organic content at the bottom of the pond can be greatly decreased, and a substrate is effectively improved; the chub bred in the mixed mode has a good effect on adjusting the balance of algae in a water body, and the water quality can be effectively improved; the substrate and the water quality of the pond can be comprehensively improved by throwing in the fingerlings first, the harm caused by organic matter in bottom mud to the penaeus vannamei boone larvae are further reduced, and the stocking success rate of the penaeus vannamei boone larvae is ensured; the perfect combination of the penaeus vannamei boone, the crucian and the chub has great significance on penaeus vannamei boone breeding environment adjustment, disease prevention and income increase.

Description

Technical field [0001] The invention relates to the field of aquaculture methods, in particular to a high-efficiency ecological breeding method suitable for vannamei prawns. Background technique [0002] Since the introduction of Penaeus vannamei to my country in 1988, due to its strong disease resistance, low salt tolerance, and fast growth, the aquaculture area has been continuously expanded, and the output has also been continuously broken, and good economic and social benefits have been achieved. However, outbreaks of prawn epidemics still occur from time to time, threatening the prawn farming industry. In recent years, the success rate of prawn cultivation has gradually declined. Traditional prawn culture methods are intensive pond culture and high-level pond culture. Both are an autotrophic ecosystem with high organic load. There are few biological species in the system, simple food web, weak self-regulation ability, and poor stability. Studies have shown that many ecologi...

Problems solved by technology

The above-mentioned polyculture with tilapia effectively solves this problem, but shrimp culture is a high-load culture system, which will cause double burdens on the bottom and water quality during the culture process. If the water and bottom cannot be effectively controlled, It will eventually lead to the deterioration of the aquaculture water environment and cause the occurrence of diseases

Such as Chinese patent 200910041547.5 "an ecological breeding method for polyculture of tilapia and Litopenaeus vannamei", the disclosed polyculture method is because tilapia is an omnivorous fish, and can compete with prawns for bait, which is easy to cause bait The improvement of the system cost, and the culture method disclosed in Chinese patent 201310741051.5 "a low-salinity culture method of Penaeus vannamei" is mainly mixed culture with silver carp and bighead carp, because the filter feeding effect of silver carp and bighead carp can effectively improve water quality , can adjust the balance of algae in the water body, but it has little effect on improving the bottom quality, and the bighead carp has strong predation and can consume a large amount of bait for prawns, which is not dominant in the economic cost of breeding
