Sleeve type net-cage system used for co-culturing of deep-sea fish and shallow-sea fish

Abstract

The invention discloses a sleeve type net-cage system used for co-culturing of deep-sea fish and shallow-sea fish. The sleeve type net-cage system comprises culturing floating platforms which float onsea surface, a first net cage body arranged right below the culturing floating platforms, and second net cage bodies fixedly arranged at the peripheries of the culturing floating platforms, wherein the first net cage is liftably and slidably arranged in the interior of a second accommodation space of the culturing floating platforms through slide assemblies; and ascending and descending of net cage bodies are adjusted through balancing weights arranged on the culturing floating platforms. The sleeve type net-cage system used for co-culturing of the deep-sea fish and the shallow-sea fish provided by the invention has the following advantages: the structure is simple; the use is convenient; the lift-drop control of the first net cage body can be rapidly and stably realized according to needs, so the needs of culturing of the deep-sea fish are met; the depth of descending is adjustable; the second net cage bodies are arranged with a height of water surface aligned with the culturing floating platforms, so the needs of culturing of the shallow-sea fish are met; meanwhile, electric energy applied in the sleeve type net-cage system provided by the invention is converted from clean solarenergy, and an external electric supply line is not needed, so excessive consumption of the electric energy with other sources is not generated, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of fishery, in particular to a nested net cage system for co-culture of deep-sea fish and shallow-sea fish. Background technique [0002] The food supply of traditional deep-sea fish usually needs to be fished in the ocean by large fishing boats. It usually takes several months or dozens of days to go to sea. There is actually a period of time before consumers make food, so in terms of freshness, hygiene, taste, etc., there is still a difference between the taste of fresh fish and the general deep-sea fish. It is special and cannot be mass-produced at all. The main reason is that the actual deep-sea high-pressure aquaculture living environment is not easy to create. In terms of current aquaculture technology and fishery development, the most common ones are still only for general freshwater and seawater aquaculture. It is impossible to do deep-sea fish farming; moreover, with the current farming methods, mo...

[0002] The food supply of traditional deep-sea fish usually needs to be fished in the ocean by large fishing boats. It usually takes several months or dozens of days to go to sea. There is actually a period of time before consumers make food, so in terms of freshness, hygiene, taste, etc., there is still a difference between the taste of fresh fish and the general deep-sea fish. It is special and cannot be mass-produced at all. The main reason is that the actual deep-sea high-pressure aquaculture living environment is not easy to create. In terms of current aquaculture technology and fishery development, the most common ones are still only for general freshwater and seawater aquaculture. It is impossible to do deep-sea fish farming; moreover, with the current farming methods, most of them are embankment or pond-digging farming methods, and the types of fish that can be farmed are mostly limited to common offshore or shallow water fish, For shrimp and shellfish, it is impossible to improve the farming technology of diverse and higher economic value. How to make the value of the farming industry take into account the actual farming technology, food hygiene and fish supply stability, with the current farming cages and farming methods, Can not meet the demand for diversification of farming
