The mode that current aquaculture often used the culture box of sinking the bottom carries out, specifically is: the culture box is connected with the water surface floater by using the rope, and the culture box is lifted by the rope for operation during fishing. Therefore, the traditional bottom-sinking aquaculture tank mode has the defects of low efficiency, high danger, high labor intensity and the like. In addition, the existing culture method of the submerged culture box is only limited to shallow sea culture, so the culture operation range is narrow.
In order to solve the problems of high labor intensity, low efficiency and the like of aquaculture of the traditional aquaculture tank, for example, Chinese patent with the bulletin number of CN112425539A and the bulletin date of 2021, 03 and 02 discloses a interlayer type intelligent aquaculture tank, which can be accurately placed at different depths in water, an intelligent propulsion device of the tank can place and move a filter screen tank therein, so that the filter screen tank can be placed at different positions in the aquaculture tank, but the aquaculture tank still needs manual operation when being placed into water and salvaged, and can only be placed in a specific aquaculture pond, so that the problem of limited selection of aquaculture operation positions still exists. In the prior art, the problems of high labor intensity, low operation efficiency and narrow culture range are not effectively solved.
On the other hand, aquaculture of shellfish, snails, barnacles, oysters, corals, and the like requires attachment growth. Most of the existing culture bodies are made of metal, but the metal is not beneficial to biological attachment. Meanwhile, conventional metals are subject to corrosion by seawater, limiting the service life of the culture. Thus, there is a need in the art to increase biofouling and improve the life span of farmed bodies.
