Technical Field

The utility model relates to an artificial fish nest technical field, more specifically say, relate to an artificial fish nest suitable for there is the action of nesting to produce viscidity ovum fish indoor.

Background

When the fishes with adhesive eggs with nesting behaviors are bred, the male fishes have nesting behaviors, and the adhesive fertilized eggs need to be adhered to aquatic plants or pebbles to complete the embryo development process. Generally, various economic fishes are mixed and cultured in a culture water body, the phenomenon that big fishes swallow fish eggs is obvious, and the collection rate and the hatching rate of seedlings are low easily caused by the absence of a fixed spawning place.

Nowadays, for the existing indoor egg receiving device and hatching device for the fishes laying adhesive eggs, the device mainly focuses on laying eggs in a spawning pond and naturally hatching, and then manually collects the eggs and hangs flaky substances in a large-scale culture water body to collect the eggs.

However, the collecting rate of the sheet-shaped collecting device is low, the sticky eggs do not have specific attachments in the spawning pond, the sticky eggs are easily concentrated at the corner positions of the spawning pond and are adhered into a dough shape, and the fertilized eggs cannot be hatched due to oxygen deficiency. Therefore, how to solve the problem of low seedling collection rate and hatchability of the fish with laying sticky eggs and having nesting behavior is an important technical problem to be solved by the technical personnel in the field.
