Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an oxygen-increasing buffer water inlet device for a fish egg hatching pond. Background Technique

[0002] Fish farming, that is, the reproduction, breeding and stocking of fish, is also called aquaculture, fish farming and pisciculture. It plays an important role in maintaining food supply, fishing and expanding fishing areas. Through fish farming, many species have been successfully introduced into new areas. Fish are oviparous organisms. During the hatching process, there must be abundant oxygen in the water body. Oxygen is required for respiration during embryonic development, a large amount of oxygen is needed after the appearance of the tail bud, and even more oxygen is needed during the larval stage. Whether it is indoor dry hatching or outdoor pond hatching, sufficient oxygen supply should be noted.

[0003] In the prior art, Chinese Patent Publication No. CN212436943U discloses a suspended fish egg hatching pond, which relates to the technical field of aquaculture. The fish egg hatching pond includes a cement hatching pond. A plurality of mutually spaced hatching grooves are formed on the cement hatching pond. A suspension pond is formed at the bottom of the hatching groove. A filter cover is arranged at the upper edge of the suspension pond opening in the hatching groove. The upper and lower ends of the filter cover are open. A fish egg conveying device is arranged outside the cement hatching pond. The fish egg conveying device is respectively communicated with each suspension pond. The suspended fish egg hatching pond of the utility model forms a suspension pond at the bottom of the hatching groove, and pumps fish eggs from the bottom opening into the suspension pond through the fish egg conveying device, so that the hatching water mixed with fish eggs can be pumped into the suspension pond from the bottom of the suspension pond. While pumping fish eggs and hatching water, the water body pumped in can also form a vortex in the suspension pond, disturbing the water bodies in the suspension pond and the hatching groove, preventing fish eggs from depositing, and greatly improving the survival rate and hatching rate of fish eggs.

[0004] During the fish egg hatching process, it is necessary to store water and oxygenate the inside of the hatching pond. During the water storage and oxygenation process, a large number of bubbles pour into the inside of the hatching pond. Since fish eggs are fragile organisms, when the bubbles are too large, the fish eggs will be damaged. Therefore, during the water storage and oxygenation process, how to prevent the bubbles from impacting the fish eggs is an urgent problem to be solved. Content of the Utility Model
