Hatchery construction and hatching method for freshwater lobster seeds

Abstract

The invention discloses hatchery construction and hatching method for freshwater lobster seeds. A hatchery comprises a reservoir, a water purification tank, a parent lobster breeding pond, a hatchingpond and a larva lobster breeding pond, wherein a closed lobster seed breeding mode is adopted in the hatchery so that the incidence rate can be reduced, and through arrangement of a circulating purification treatment system, aquaculture water can be recycled, so that sewage discharge is reduced, and the environment is protected; a grid is arranged when the lobster seeds are hatched, larvae lobsters pass through grid holes and fall onto the bottom of the hatching pond after leaving parent lobsters, and by means of water flow, the larvae lobsters enter the larvae lobster breeding pond, so thatharm of the parent lobsters to the larvae lobsters is avoided; through addition of tiles, PVC pipes and other shields in the parent lobster breeding pond, a shelter of the parent lobsters is increased, and the phenomenon of mutual killing of the parent lobsters is reduced; and through the hatching method, more larvae lobsters are bred, a high survival rate is achieved, and the benefits of farmerscan be increased greatly.

Description

technical field [0001] The invention belongs to the field of lobster breeding, and more specifically relates to a method for constructing a freshwater lobster seed hatchery. Simultaneously, the invention also relates to a freshwater lobster seed hatching method. Background technique [0002] In recent years, the Australian freshwater lobster farming industry has developed rapidly. However, the high-density farming model makes the ecosystem structure of the farming environment single and weak in resistance. Moreover, the lobster and seedlings in the existing lobster hatching pool are all in the same pool. If the larvae are not separated in time after the lobster hatches, it is easy to have the phenomenon of eating the larvae, resulting in low lobster yield, and separating the larvae is particularly troublesome and time-consuming. Laborious and labor-intensive. Contents of the invention [0003] The object of the present invention is to provide a hatchery construction and ...

Problems solved by technology

[0002] In recent years, the Australian freshwater lobster farming industry has developed rapidly. However, the high-density farming model makes the ecosystem structure of the farming environment single and weak in resistance, which can easily lead to deterioration of water quality and frequent occurrence of shrimp diseases, which eventually lead to a large number of shrimp deaths and low survival rates.

Moreover, the lobster and seedlings in the existing lobster hatching pool are all in the same pool. If the larvae are not separated in time after the lobster hatches, it is easy to have the phenomenon of eating the larvae, resulting in low lobster yield, and separating the larvae is particularly troublesome and time-consuming.
