Problems solved by technology

[0002] Cage culture is a relatively common way of aquaculture. Through cage culture, it is convenient for fry feeding and salvage in the later stage. However, during the process of cage culture, the cage is fixed in the water, so it is inconvenient to adjust the depth into the water surface. , affecting the stability of the water tank, it is easy to cause turbulence of fry and low survival rate, which increases the cost of breeding, and most of the existing net cages are single-layer structure, and the growth cycle of fry is different, which is easy to cause big fish and small fish to be confused during salvage. When salvaged, manual sorting is required, which greatly reduces the fishing efficiency, and small fish are prone to die due to lack of water during the sorting process, which will also increase the cost of breeding

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] see Figure 1-5 , the present invention provides a technical solution: a net cage for aquaculture, comprising an outer net cage 1, the outer net cage 1 and the inner net cage 36 are square structures, which can ensure sliding connection while avoiding relative rotation, and improve the connection efficiency. Stability, to ensure the adaptability of the breeding environment, the outer surface of the outer cage 1 is fixedly covered with a small hole isola...

Abstract

The invention discloses an aquatic product breeding net cage. The net cage comprises an outer net cage body, and a small-hole isolation net fixedly wraps the outer surface of the outer net cage body;the inner bottom face of the outer net cage body is fixedly connected with a connecting column through a connecting rod; a connecting hole is formed in the connecting column, and a floating cylinder is fixedly connected to the lower surface of the connecting rod through a fixing rod; the interior of the connecting hole is in sliding connection with a pull rope, and the lower surface of the pull rope is fixedly connected with a balancing weight through a pull ring; the outer surface of the connecting column is in sliding connection with an inner net cage body through a connecting cylinder, theouter surface of the inner net cage body is slidably connected to the inner side surface of the outer net cage body, and a large-hole isolation net fixedly wraps the inner side surface of the inner net cage body. According to the aquatic product breeding net cage, by means of the outer box structure connected with the balancing weight and the pull rope and the outer net cage body connected througha hinged lengthened cylinder, the convenience and stability of breeding can be greatly improved, the breeding effect is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a net cage for aquaculture. Background technique [0002] Cage culture is a relatively common way of aquaculture. Through cage culture, it is convenient for fry feeding and salvage in the later stage. However, during the process of cage culture, the cage is fixed in the water, so it is inconvenient to adjust the depth into the water surface. , affecting the stability of the water tank, it is easy to cause turbulence of fry and low survival rate, which increases the cost of breeding, and most of the existing net cages are single-layer structure, and the growth cycle of fry is different, which is easy to cause big fish and small fish to be confused during salvage. When salvaged, manual sorting is required, which greatly reduces the efficiency of salvage, and small fish tend to die due to lack of water during the sorting process, which will also increase the cost of breeding. ...
