In an embodiment of the present invention, the frame is further provided with a hand guard bar.

Compared with the background technology, the technical scheme has the following advantages:

the utility model discloses 5 pieces of warp knitting knotless net piece sew up into the netting, fixes on the frame, and the size of a dimension sets up different outer nets and intranet and sets up interval 0.8-1.2 meters, can breed the production in the natural sea area. Wherein, the inner net is used for culturing fishes with higher economic value, such as red sea bream, large yellow croaker, red spotted grouper, etc., and the fishes which can eat the net coat and attach fouling organisms, such as black sea bream, siganus oramin, etc., are cultured between the outer net and the inner net (without bait feed). The device is convenient to use, simple in structure, low in cost and capable of being repeatedly used. The net has obvious effect of removing fouling organisms attached to the net, the service life of the net can reach 12-24 months, and the fouling organisms on the net do not need to be manually removed.

Detailed Description

Example 1

Referring to fig. 1 to 3, the utility model relates to a breeding device for netting adhered with fouling organisms to be removed, which comprises a square frame 1, wherein each side of the frame 1 comprises an outer frame 1-1 and an inner frame 1-2 which are arranged in parallel, and connecting rods 1-3 are arranged between the outer frame 1-1 and the inner frame 1-2 at intervals. Each frame 1 is a small unit, and the four square frames 1 form a square large unit. Wherein the adjacent sides of the small cells share the frame 1.

Floating blocks 3 are bound on the frame 1 at intervals, and hand guards 2 are arranged on the inner frame along the frame 1 to facilitate people to walk on the frame 1.

The bottom of the frame 1 is provided with an outer net 4 and an inner net 3, the outer net 4 is a cultivation net with an opening at the top and composed of four nets and a bottom net, the four nets are arranged at the front, the back, the left and the right, and 5 warp-knitted knotless net pieces are sewn into a netting; the inner net 3 is also a breeding net with an opening at the top and composed of four nets and a bottom net at the front, the rear, the left and the right, and 5 warp-knitted knotless net sheets are sewn into a netting. The interior of the inner net is a first breeding area 7, and a second breeding area 8 is formed between the outer net and the inner net.
