Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an aeration device for a breeding pond for oyster larvae. Background Art

[0002] It usually takes about 30 days for oyster larvae to hatch and finally settle. During the larval cultivation process, the dissolved oxygen content is generally required to be higher than 4.5 ml / L. The amount of aeration needs to be adjusted according to the density, development stage and water quality of the larvae to ensure that there is enough dissolved oxygen in the water. Generally, the amount of aeration per minute is required to reach 1% to 1.5% of the total water body. Aeration can increase the oxygen in the water body, evenly distribute the larvae and bait, and is conducive to the oxidation of metabolites.

[0003] Under the condition of 23-25℃, the fertilized eggs of long oysters develop into D-shaped larvae in about 22 hours. During the hatching process of the fertilized eggs, slight inflation is required. If the inflation volume is too large, it is easy to cause embryonic malformation. It is difficult for the existing inflation device to ensure the consistent gas output of each air stone. Often, some inflatable air stones are slightly inflated, while other air stones are inflated too much or too little, resulting in uneven inflation of the hatching pool. The existing inflation device is connected to the air stone by multiple inflation hoses for inflation. Too much inflation is easy to breed bacteria, inconvenient management, uneven inflation, troublesome operation, and difficult cleaning.

[0004] Based on this, an aeration device for a breeding pond for oyster larvae is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content
