Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture, and particularly relates to a fish egg collection and incubation device. Background Art

[0002] Fish egg collection and spawning is an important part of aquaculture. It is necessary to concentrate adult fish into spawning ponds, continuously collect eggs laid by adult fish, and transfer them to spawning ponds to provide suitable water temperature and spawning environment to improve the success rate of fish egg spawning.

[0003] In contrast, a Chinese patent with announcement number CN217936933U discloses a fish egg spawning and collection circulation device, including a broodstock spawning pond, an egg collecting pond, a water reservoir, an egg collecting tube, an egg delivery tube, an egg isolation tube, a drain pipe and a water pump. The bottom of the broodstock spawning pond is provided with an egg collecting tube perpendicular to the bottom of the pond and extending into the pond, a fish egg filter head is provided on the top of the fish egg collecting tube, and fish egg collecting holes are provided around the bottom. The bottom of the fish egg collecting tube is connected to the egg delivery tube, and the other end of the fish egg delivery tube is connected to the fish egg collecting pond. The bottom of the fish egg collecting pond is provided with an egg isolation tube perpendicular to the bottom of the pond and extending into the pond, the bottom end of the fish egg isolation tube is connected to the drain pipe, and the other end of the drain pipe is connected to the water reservoir. A water pump is provided in the water reservoir, which is connected to the broodstock spawning pond through a pump tube. The positions of the broodstock spawning pond, the fish egg collecting pond and the water reservoir are successively lowered.

[0004] However, the water reflux in the above-mentioned patent is irregular, which easily scatters the fish eggs and slows down the collection of the fish eggs. Therefore, a new device needs to be designed. Utility Model Content
