The invention discloses a single-point
mooring type
flounder paralichthys aquaculture net cage, which comprises a main body framework, a netting, sunken stone, a
mooring rope and a
mooring system, wherein the netting is tied on the main body framework, the main body framework is of a rectangular structure formed by connecting
pipe fittings, the bottom of the main body framework is connected with the sunken stone through hanging ropes, the
mooring system is a single-point
mooring system, and comprises an anchor, an anchor chain and floating balls, the anchor sinks in water bottom, the anchor chain is connected with the mooring
rope and the anchor, and the floating balls float on the water surface. The net cage disclosed by the invention has the advantages that the exchange efficiency of
water flow inside and outside the net cage can be improved, so that the effective
oxygen supply in the net cage is improved; the net cage can drift along the
water flow direction through the single-point
mooring system adopted by the net cage, and the
impact of the
water flow on a cage body is reduced; a bottom framework and an upper framework of the net cage are connected into a whole, the balance capability of the bottom of the net cage can be improved, and a safe and reliable platform is provided for
flounder paralichthys growth.
