Seaweed breeding device combined with up-and-down breeding net cages and application method

Abstract

The invention relates to the technical field of ecological breeding, in particular to a seaweed breeding device combined with up-and-down breeding net cages and an application method. The seaweed breeding device comprises a flexible culturing raft frame and the up-and-down breeding net cages on two sides of the flexible culturing raft frame, wherein the flexible culturing raft frame comprises first floating ropes on two sides and a second floating rope at the middle part; hooks and floating balls are arranged on each first floating rope; floating balls are arranged on the second floating rope;two ends of each of seaweed seedling ropes are fixed on the hooks corresponding to the first floating ropes on the two sides, and are borne by the second floating rope at the middle part; chains arearranged at two ends of each of the first floating ropes and the second floating rope; a chain hook is arranged at the free end of each chain; the chains are twined on the edge of the upper end of theup-and-down breeding net cage at a corresponding end and are used for hooking any chain hole through the corresponding chain hook for binding; and fixing ropes are arranged at joints of two ends of each first floating rope and the corresponding chains, and the other end of each fixing rope is fixed to a submarine fixed seat below each up-and-down breeding net cage. According to the seaweed breeding device disclosed by the invention, the up-and-down breeding net cages are utilized to adjust a breeding water layer or avoid stormy waves, and the seaweed breeding device conforms to ecological breeding development requirements.

Description

technical field [0001] The invention relates to the technical field of ecological cultivation, in particular to a seaweed cultivation device combined with a sinking-floating cultivation net cage and a method for using it. Background technique [0002] Seaweed is not only a regulator of the marine environment, but also a high-quality bait for sea treasures (such as sea cucumbers, abalones and sea urchins, etc.). At present, the main species of seaweed culture in my country mainly include: kelp (Laminaria japonica), Gracilaria (Gracilaria), wakame (Undaria), seaweed (Pyropia), etc. These types of seaweed culture are mainly concentrated in shallow seas within the 20-meter isobath. However, due to cost, technology, risk and other reasons, the offshore deep-water aquaculture of seaweed has not yet been effectively carried out. [0003] At present, the cultivation of kelp, Gracilaria and wakame basically adopts the traditional raft cultivation method, that is, the piling machine i...

Problems solved by technology

This farming method can only be applied to offshore and inner bay waters, and in recent years, due to high-density and overloaded offshore farming, the environment in coastal waters has deteriorated year by year, various diseases have occurred frequently, and the production and quality of aquaculture have greatly declined

[0004] In the prior art, there are some invention patent technologies aimed at cultivating seaweeds in deep water areas. For example, the Chinese invention patent whose authorized announcement number is CN101822207A discloses a construction method of kelp culture rafts in deep water and high areas. This method is only based on The characteristics of the deep water area increase and deepen the fixation of the root stick, and the fixing method of the thick root rope is adopted, but because it is in the offshore deep water area (the water depth exceeds 20 meters), this solution is still difficult to fix, and the offshore deep water area ( The water depth is more than 20 meters) and there are often large waves. Once the fixation is not firm enough, it will easily cause losses to seaweed cultivation.
