A device for collecting and incubating shrimp seedlings

technical field

The utility model relates to the field of aquaculture, in particular to a shrimp fry collecting and hatching device.

Background technique

Because the shrimp seedlings are small and fragile, they are very sensitive to changes in environmental conditions, so it is necessary to master the correct methods when hatching and raising them. Shrimp seedlings are moved from indoor nursery ponds to grow-out ponds, and the light conditions, water temperature, salinity, water quality, and the type and quantity of bait of the water body all undergo considerable changes. This period is also the period that has the greatest impact on the survival of shrimp seedlings.

In the common shrimp hatching device, the adult shrimp, shrimp eggs, and shrimp seedlings are placed together for breeding. The management is extensive, and there is no detailed management method for water temperature and bath oxygen. It is also easy to mix with other organisms to grow, which will cause great damage to the shrimp seedlings. , leading to low hatchability and survival rate of shrimp seedlings.
