Description

Technical Field

[0001] The utility model relates to the technical field of fish reproduction, hatching and protection, in particular to a natural reproduction and hatching protection device for rare fish. Background Art

[0002] Rare fish refer to those fish that are rare in nature, protected or endangered. These fish may decrease in population due to environmental damage, overfishing, climate change and other reasons. Protecting the natural reproduction and hatching of rare fish is one of the important measures to ensure the health and survival of their populations. Special nature reserves or fishing bans are usually set up to protect the habitats of rare fish and reduce the impact of human activities on their living environment. For some specific populations of egg-laying rare fish, they may be placed in the same fish tank to increase the natural reproduction rate of this fish.

[0003] Most of the existing fish tanks place water plants or pebbles, so that oviparous rare fish can lay eggs on the surface of the water plants or pebbles. However, due to the lack of protection and the very noisy artificial environment, the parent fish may be frightened and disturbed after spawning, and the parent fish may swallow the eggs. In addition, if there are unfertilized eggs among the spawning, these eggs cannot develop normally and will cause mold. If not handled in time, the moldy eggs will infect the surrounding normal eggs, thereby greatly reducing the reproduction rate.

[0004] In view of this, we propose a natural reproduction and hatching protection device for rare fishes. Utility Model Content

[0005] Therefore, the purpose of the utility model is to provide a natural reproduction and hatching protection device for rare fishes to solve the above-mentioned problems in the prior art.
