Red swamp crayfish factory breeding technology

Abstract

The invention discloses a red swamp crayfish factory breeding technology. The red swamp crayfish factory breeding technology includes the following steps that firstly, a breeding workshop is built; secondly, a multilayer three-dimensional breeding aquarium frame is arranged in the breeding workshop, and each layer of breeding aquarium frame is provided with a plurality of breeding aquariums which are respectively an independent system; thirdly, parent shrimps are put into the breeding aquariums, self-mixed crayfish gonadal development promoting fodder is regularly fed to promote synchronous bulk oviposition of crayfishes, and after oviposition of the crayfishes is finished, shrimps with eggs are uniformly hatched in a hatching aquarium; fourthly, after hatching of zygotes, plankton is fed, after metamorphosis of larvae is finished and the larvae become juvenile crayfishes and leave from parent bodies, the crayfishes can be caught, and breeding is completed. A five-in-one artificial induction breeding technology is adopted to promote synchronous bulk oviposition of the crayfishes, breeding is carried out in a large-scale mode, and the technical problem that breeding seeds are in short supply is solved; meanwhile, due to the adoption of multi-layer three-dimensional full-automatic breeding, the number of emerging seeds per unit area is greatly larger than the number of emerging seeds of cement pit and soil pool breeding.

Description

technical field [0001] The invention relates to a culture technology, in particular to the industrial breeding technology of Procambarus clarkii. Background technique [0002] At present, the existing shrimp breeding technology mainly adopts cement pond breeding and earthen pond breeding and breeding. The emergence rate is low, which cannot meet the market demand, and the spawning is not uniform, so it is difficult to supply shrimp fry of the same specification in batches. [0003] However, some farmers have used exogenous hormone injection or eye stalk removal to induce crayfish to spawn synchronously. Although the purpose of synchronous spawning has been achieved, the operation is complicated and costly, making it difficult to promote on a large scale. Contents of the invention [0004] The technical problem solved by the present invention is to provide the industrial breeding technology of Procambarus clarkii to solve the problems raised in the above-mentioned backgroun...

[0002] At present, the existing shrimp breeding technology mainly adopts cement pond breeding and earthen pond breeding and breeding. The emergence rate is low, which cannot meet the market demand, and the spawning is not uniform, so it is difficult to supply shrimp fry of the same specification in batches.

[0003] However, some farmers have used exogenous hormone injection or eye stalk removal to induce crayfish to spawn synchronously. Although the purpose of synchronous spawning has been achieved, the operation is complicated and costly, and it is difficult to promote it on a large scale.
