Aquaculture net cage

Abstract

The invention discloses an aquaculture net cage which comprises a rectangular cage body; the cage body is provided with a bottom plate, two long side lateral plates and two short side lateral plates; each of the long side lateral plates is of a steel plate structure; each of the short side lateral plates is of a steel wire mesh structure or a steel wire mesh is arranged at the upper part of one side in the short side lateral plate, a steel plate is arranged at the lower part, and the steel wire mesh structure is formed on the other side; the short side lateral plate on the left side is inclined, and the short side lateral plate on the right side is vertical; both the long side lateral plates and the short side lateral plates are provided with reinforcing bars; a corridor is arranged at the top of the rectangular cage body; an aeration fan is arranged on the corridor; an aeration pipeline is connected to the aeration fan and extends to the bottom of the cage body. The aquaculture net cage disclosed by the invention has the benefits that the fish farming yield per mu rises, so that the fish yield with a floor area of 1 / 5 is equivalent to mu yield obtained by traditional farming; the plate type structure of each of the long side lateral plates can be effectively isolated from an external water body, so that dissolved oxygen and baits are controlled in equipment, and the loss of the baits is reduced.

Description

technical field [0001] The invention relates to the aquaculture industry, in particular to an aquaculture net cage. Background technique [0002] With the rapid development of fish farming this year, the traditional pit pond farming method shows low economic efficiency. On the one hand, the area of ​​the water body is large, the amount of bait fed is large, the amount of bait wasted is large, and the area of ​​fish activity is large, the area used for disinfection and other measures for diseases and other diseases is large, and the cost of residual bait and disinfection is high. On the other hand, because of the pit-pond farming method, the area is relatively fixed, mostly stagnant water, a large amount of fresh water supply, a large amount of residual bait, the water quality deteriorates year by year, and the yield per mu decreases year by year. On the one hand, it reduces the economic benefits of farmers. [0003] Therefore, designing a kind of high-density aquaculture n...
