Ocean surface hanging abalone platform and abalone breeding oxygenation equipment

Abstract

The invention discloses an oxygenation device for abalone culture. The oxygenation device comprises an air blower, a driving mechanism, an air delivery pipe and an aeration disc component, wherein the aeration disc component is arranged underwater, the air outlet of the air blower is connected with the aeration disc component through the air delivery pipe, the aeration disc component comprises a plurality of rings arranged concentrically and two magnet groups, the plurality of rings are arranged between the two magnet groups, the rings are hollow, the inner cavities of two adjacent rings are communicated through a connecting pipe, the connecting pipes are arranged radially, air holes are arranged on the rings, and the air delivery pipe is internally provided with a secondary pipe which is communicated with the aeration disc component. Many tests prove that after oxygenation by the oxygenation device, the death rate of hanging culture abalone can be effectively lowered by 25%, and the yield can be improved by 30%. For the ocean surface abalone hanging culture platform provided with the oxygenation device, the oxygen dissolved in water can be effectively increased, deposited sticky scaling substances are reduced, the environment is not polluted, and local ecological balance is not damaged.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a platform for hanging abalone on the ocean surface and abalone breeding oxygenation equipment. Background technique [0002] The most important thing in aquaculture is to maintain a certain amount of nutrients in the water. Many aquatic mortality events are caused by insufficient oxygen supply. The water body suitable for aquaculture should meet the following requirements: 1) the water body has a certain fluidity, and the water quality of the aquaculture water body is kept stable; 2) it has a certain dissolved oxygen coefficient; 3) the water body has a uniform water temperature. At present, the common aquaculture oxygenation equipment mainly has the following disadvantages. First, the equipment (aeration pan) installed underwater will form sticky scales such as fine sand on the surface after years of use. Cleaning after taking out the equipment from the bottom of the water i...

Problems solved by technology

At present, the common aquaculture oxygenation equipment mainly has the following disadvantages. First, the equipment (aeration pan) installed underwater will form sticky scales such as fine sand on the surface after years of use. Cleaning after taking out the equipment from the bottom of the water is time-consuming and laborious, and the cleaning efficiency is low. Second, the oxygenation equipment is directly added to the water through the oxygenation equipment. The water has not been treated in advance, which makes the oxygen-dissolving effect of the water poor.
