Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aquaculture, in particular to a fish egg collecting device for aquaculture. Background Art
[0002] In the process of fish breeding, optimizing germplasm resources is a vital task. In order to achieve this goal, we usually need to carefully select healthy, fast-growing and disease-resistant broodstock from the fish pond for artificial spawning and breeding. By selecting these high-quality broodstock, we can ensure that the offspring of fish inherit their excellent genetic characteristics, thereby improving their growth performance and disease resistance, and thus maximizing the breeding benefits.
[0003] Generally speaking, people will press the abdomen of the parent fish to encourage the eggs to be discharged through the reproductive opening. However, this method is not practical in practice because the eggs can easily slide out along the belly of the fish during the discharge process. This not only increases the difficulty of collection, but may also cause damage and loss of the eggs. In addition, pressing the abdomen of the parent fish multiple times may cause damage to the fish body and even affect its subsequent reproductive ability.
[0004] For this reason, a fish egg collecting device for aquaculture is proposed. Utility Model Content
