specific Embodiment approach 1

[0016] Specific implementation mode one: combine figure 1 , figure 2 and image 3 Illustrate this embodiment, the device of a kind of fish large water surface breeding described in this embodiment, it comprises central island 2, N buoys 3, fixed pole 5, covering net 6, side fence 7 and bottom class 8; 2 and the bottom ends of the buoys 3 are connected with fixed anchors 10 by cables 9 respectively, and the center island 2 and the buoys 3 are rigidly connected by fixed rods 5; Link rods 4 are connected to the center island 2 at the same position respectively, and the remaining buoys 3 are connected to adjacent buoys 3 with link rods 4. The number of link rods 4 between two buoys 3 is M, and the number of link rods 4 between Hinged to each other; a cover net 6 is set above the water surface in the area enclosed by the link bar 4 and the central island 2; a side fence 7 is set under the link bar 4, and a bottom frame 8 is set at the bottom of the side net 7; wherein, N≥3 , M ...

specific Embodiment approach 2

[0018] Specific implementation mode two: combination figure 1 This embodiment is described. This embodiment further limits the device for stocking fish on a large water surface as described in Embodiment 1. The central island 2 is provided with a test bench 1 . Others are the same as in the first embodiment.

specific Embodiment approach 3

[0019] Specific implementation mode three: combination figure 1 This embodiment is described. This embodiment further defines the device for stocking fish on a large water surface as described in Embodiment 1. The center of the central island 2 is higher than the edge. Others are the same as in the first embodiment.

[0020] The upper surface of the center island 2 is slightly roughened to increase friction.

Abstract

The invention discloses a device for fish culture on an open lake, relates to a fish aquaculture device, and aims to solve problems in the stocking and releasing process of existing natural water and particularly large-area natural water. The device comprises a central island, buoys, fixing rods, a covering net, a side enclosure net and a bottom line, the central island is rigidly connected with the buoys though the fixing rods, the buoys are connected through link rods, the covering net is arranged on the water surface of an enclosure area of the link rods and the central island, the side enclosure net is arranged below the link rods, and the bottom line is arranged at the bottom end of the side enclosure net. One ultra-large water area is enclosed into a relatively independent closed space, enemies from air and water are avoided, the survival rate of seedlings is effectively increased, water quality and environments in the closed space are completely consistent with those of surrounding natural water, diseases of the seedlings are decreased, the survival rate is increased, the usage amount of antibiotics is reduced, the device is green and environmentally friendly, and fish is safer and more healthy to eat.

Description

technical field [0001] The invention relates to a fish breeding device. Background technique [0002] With the continuous increase of environmental protection and people's increasing emphasis on aquatic food safety, higher requirements have been put forward for aquaculture technology, and traditional high-density farming has not met the requirements of the times. Large water surface grazing farming (hereinafter referred to as stocking) that is close to the natural growth has attracted people's attention; at the same time, in order to protect species diversity, protect rare aquatic species resources and achieve sustainable development, it is necessary to use them in the original habitat. Breeding and release (hereinafter referred to as release); therefore, improving the survival rate of fish in large water bodies has become the key to current aquaculture. [0003] The existing natural water body stocking and release technology is relatively primitive, especially freshwater a...
