Embodiment Construction

[0030] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] The reference signs and components involved in the accompanying drawings are as follows:

[0032] 1. Lateral outer spud assembly 11. Lateral inner spud assembly

[0033] 2. Longitudinal outer spud assembly 21. Longitudinal inner spud assembly

[0034] 3. Horizontal template 4. Vertical template

[0035] 5. Knee Bar 6. Waist Bar

[0036] 7. Gate 8. Cage

[0037] 9. Floaters

[0038] For ease of description, the following descriptions use the terms "horizontal" and "longitudinal", where the horizontal is defined as the direction in which the river channel follows the water flow, and the longitudinal direction is defined as the direction perpendicular to the river channel following the water flow.

[0039] Please refer to figure 1 , figure 1 It is a schematic structural diagram of a device for cultivating fish and shell...

Abstract

The invention relates to a device for culturing fish and shellfish in a channel cage, which comprises a horizontal lateral positioning pile assembly, a horizontal medial positioning pile assembly, a longitudinal lateral positioning pile assembly, a longitudinal medial positioning pile assembly, horizontal templates, longitudinal templates and a cage. A horizontal template supporting rod is provided between the horizontal lateral positioning pile assembly and the horizontal medial positioning pile assembly. A longitudinal template supporting rod is provided between the longitudinal lateral positioning pile assembly and the longitudinal medial positioning pile assembly. Cages are arranged on both sides of the horizontal template. Cages are connected by the cable, and the cable is connected with floating objects. The horizontal lateral positioning pile assembly and the longitudinal lateral positioning pile assembly are provided with knee protecting rods and waist protecting rods. The distance of the horizontal template or the longitudinal template from the surface of water is 30cm. The device for culturing fish and shellfish in the channel cage has the advantages of good safety, low cost of cultivation, good flexibility, reduced stress of fish, and wide application prospect in the channel cage culture of river.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a device for facilitating the cultivation of fish and shellfish in cages in river courses. Background technique [0002] Cage culture is a form of intensive farming. Cages can be set up in rivers, lakes and various forms of waters to breed different species of fish and shellfish. Cage culture is a farming method with low investment, high benefit and promising development. It has developed rapidly in the past ten years and has achieved remarkable results. [0003] For river fish culture, the prior art adopts cage culture mostly. The net cage is placed in the center of the river, the top of the net cage is tied with floats, and there are heavy objects at the bottom to maintain the space for fish activities. In addition, it is necessary to use a long line to connect the top of the cage to the stakes on both sides of the river to prevent the cage from drifting away with the cu...
