Breeding floating body assembly and breeding floating body system

Abstract

The invention provides a breeding floating body assembly and a breeding floating body system. The breeding floating body assembly comprises a body structure, at least one first buoyancy element and a lifting groove assembly. The first buoyancy element is fixedly arranged on the body structure, the lifting groove assembly further comprises at least one lifting rod and at least one blocking net, and the lifting rod is located on the periphery of the body structure or the first buoyancy element and can generate relative displacement relative to the body structure or the first buoyancy element. The blocking net is movably attached to or close to the lifting rod; thus, according to the breeding floating body assembly, bred fish fries can increase the breeding space size along with fish growth and size increasing.

Description

technical field [0001] The invention relates to a structure for fish fry cultivation, in particular to a culture floating body assembly and a culture floating body system that float on the water surface and can be moved and dragged, and the space for fry culture can be adjusted according to requirements. Background technique [0002] Fry culture net cage refers to the culture net cage that can be used in relatively deep waters (usually the depth is greater than 20 meters), and it is a culture equipment that has developed rapidly in the past ten years. It uses computers, new materials, pneumatics, anti-corrosion, anti-fouling (attachment), anti-ultraviolet (anti-aging) and other high-tech, even in very harsh sea conditions, it can maintain the structure system of the cage and the cultured fish. The fish are safe and sound. Many countries are gradually opening up and supporting and encouraging deep-water aquaculture. The implementation of this encouraging policy is of great s...

Problems solved by technology

[0003] For a long time, fishermen have mostly used lakes, reservoirs and other native lakes for fixed cage fish farming, which not only destroys the ecological environment of the native water, but also pollutes the water quality with feed and fish dung.

Moreover, the installation of large-scale cages also hinders the flow of water, resulting in serious negative oxidation water quality and increasing the high risk of eutrophication in lakes and reservoirs

In addition, the structure of traditional breeding net cages is fixed, and the equipment is huge. Not only is it inconvenient to move to avoid typhoons, hurricanes or incoming cold currents, but also when the fry grow up and the living space is insufficient, the space volume in the breeding tank cannot be changed. (needed for fish survival activities); can only use artificial methods to move part of the grown fish by fishing, and divide a part to another culture cage

This method is very slow and labor-intensive
