Description

Technical Field

[0001] This utility model relates to the field of aquaculture, and in particular to a three-dimensional eel farming cage structure for efficient purification in water areas. Background Technology

[0002] Eels are a high-end freshwater fish, prized for their high nutritional value, delicious flesh, lack of small bones, and versatility in cooking. They have long been recognized as a nourishing delicacy. In addition to domestic demand, my country has a long history of exporting eels, thus their delicious taste and nutritional value have always been renowned both domestically and internationally. However, due to overfishing, wild eel resources are dwindling, and the consistently high market price over the years fully demonstrates the reality of their scarcity and high price.

[0003] In the past decade or so, people have begun to explore and seek artificial eel farming to alleviate the contradiction of insufficient wild resources. However, eels have unique biological characteristics, and solving the problems of eel reproduction and artificial farming is not easy. Although after more than ten years of continuous efforts, the most commonly used method is still artificial temporary rearing, that is, raising caught eel fry in ponds or net cages, half natural and half artificially altering the farming situation. A more ideal approach is to use greenhouses, combined with the construction of artificial breeding ponds and shallow-water net cage farming techniques, which has led to significant development in artificial eel farming. In particular, the application of artificial spawning technology can effectively solve the problem of seedling resources in the farming of hermaphroditic eels, and the industrialized farming of eels will surely achieve breakthrough development.

[0004] The cage structure currently used for artificial eel farming is shown in the public notice: CN221554411U discloses a split-type eel farming device, comprising a frame, an adjustment component, a feeding component, a water distribution pipe, and a return component. The adjustment component is installed on top of the frame. The feeding component includes a water inlet box and multiple feeding boxes. The water inlet box is fixedly connected to the frame, and the multiple feeding boxes are connected to the water inlet box. The water distribution pipe is connected to the outlet end of the adjustment component, and the other end of the water distribution pipe passes through the top of the multiple feeding boxes. Multiple water outlet holes are opened at the bottom of the water distribution pipe. One end of the return component is connected to the water inlet box, and the other end of the return component is connected to the inlet end of the adjustment component. Because the water inlet box and the feeding boxes are connected, eel feces in the feeding boxes can flow into the water inlet box and be guided to the adjustment component via the return component. The adjustment component treats the wastewater and adjusts it to a water quality conducive to eel farming. Under pressure difference, the wastewater is introduced into the feeding boxes through the lower water distribution pipe. This farming device can be used for indoor farming, lowering the barrier to entry for eel farming.

[0005] The aquaculture structure caused severe water pollution during use, making it impossible to control the purification level of the aquaculture water, thus affecting the survival rate of the aquaculture. Utility Model Content
