Description

TECHNICAL FIELD

[0001] The present application relates to the field of aquaculture, in particular to an open sea suspended aquaculture net cage. BACKGROUND

[0002] Water net cage culture is a technology for intensive fish culture in natural sea area. By setting up a net cage in flowing seawater, the water quality is maintained by natural water flow, reducing the accumulation of excretion, and the dissolved oxygen content is usually maintained above 5 mg / L. Its characteristics are that it does not need land occupation or additional energy supply, relies on natural bait to reduce the bait coefficient, and the net cage can be dragged to adjust the position and facilitate live fish transportation.

[0003] There is a suspended aquaculture net cage in the prior art. The box structure of the aquaculture net cage is anchored by anchor chain and floats in seawater. The existing suspended aquaculture net cage mainly has the following deficiencies:

[0004] Firstly, since the aquaculture net cage cannot effectively adjust its position in seawater with the rise and fall of the tide, part of the aquaculture space of the aquaculture net cage is above the water surface at low tide, which reduces the actual effective aquaculture space of the net cage.

[0005] Secondly, since the aquaculture net cage is placed in seawater for a long time, the side wall of the aquaculture net cage is easy to attach marine organisms such as microalgae and macroalgae, and oysters, mussels (sea rainbows), and barnacles, which easily block the mesh of the aquaculture net cage. The water flow inside and outside the net cage is not smooth, which reduces the dissolved oxygen content in the box, and the harmful substances such as ammonia nitrogen produced by fish metabolism cannot be discharged in time, which seriously affects the health and growth rate of fish, and even leads to diseases and death. Therefore, we improve it and propose an open sea suspended aquaculture net cage. SUMMARY
