Description

Technical Field

[0001] The present application relates to the technical field of aquatic animal hatching, and in particular to a hatching device for fertilized eggs of aquatic animals. Background Art

[0002] Hatching refers to the process in which the fertilized eggs of aquatic animals (such as fish, reptiles, and some invertebrates) develop under certain conditions, break through the egg membrane or egg shell, and become larvae. The hatching process usually includes stages such as cell division, organ formation, and embryonic development of the fertilized eggs. Under suitable environmental conditions, the embryo will gradually mature and eventually break out of the shell to become a larva.

[0003] For example, a fish seed hatching device disclosed in a Chinese utility model patent with a publication number of "CN209449465U" is provided. The utility model is filled with water in the hatching bucket, and the debonded fertilized eggs are put in, and the micro-flow water and uninterrupted oxygenation are maintained. After the seedlings are hatched, the seedlings are collected through the seedling collection tube. The hatching water in the hatching bucket is fresh, the dissolved oxygen is sufficient, and the seedling hatching rate is high. In addition, an anti-escape net is provided, which can prevent the escape of the seedlings and increase the survival number of the seedlings. After the seedling collection valve is opened, the seedlings can be collected. The method is simple, time-saving and labor-saving, and the damage to the fish body is small. The whole device is not a fixed facility, which reduces the direct construction on the land, does not change the original appearance of the land, is easy to move and has low production cost. The anti-escape net is fixedly connected to the inner wall of the hatching bucket by solid glue, which is simple to make, has a long shelf life, is easy to carry, is easy to use, and has a firm bonding. The top diameter of the anti-escape net is smaller than the diameter of the bottom end, and the bottom end is thicker than the top end, which has a better effect of preventing the seedlings from escaping.

[0004] In the above patent, the hatched seedlings can be prevented from escaping the device, but the anti-escape net is fixed to the device by solid glue and is difficult to remove, making it inconvenient to clean the inside of the device. It is easy to cause impurities to remain inside the device after use, making it inconvenient for subsequent hatching work. Utility Model Content
