Problems solved by technology

However, the artificial fish reefs currently developed are mainly to construct or build various frameworks in seawater, so that they can attract fish. Some researchers have also developed artificial algae reefs, mainly artificially cultivating macroalgae seedlings on various components species, in order to achieve the purpose of natural growth and multiplication of algae, but there is very little research on the construction of artificial fish reefs with adherent organisms

Embodiment 1

[0027] The materials used in this example include: some juvenile mussels (average shell height 1.74cm), some papyrus mesh, some flat hemp ropes (width 2cm), some fine hemp ropes (diameter 1mm) , Abandoned ships and supports on ships; flat hemp ropes and fine hemp ropes, soaked in seawater for 48 hours and then dried for use.

[0028] A method of constructing a reef using mussels, comprising the steps of:

[0029] (1) peeling off the spat of the thick-shell mussels of the thick-shelled mussels that are protected by hanging bags in the sea area from the seedling protection rope and passing through a sieve of 2-3cm aperture to obtain single spat;

[0030] (2) Cut the flat hemp rope into hemp rope sections, and cut the rolled mesh into strip-shaped mesh strips; place the hemp rope section in the center of the mesh strip, and the direction of the hemp rope section is the same as the mesh strip. The length of the hemp rope section is the same, and the length of the hemp rope sectio...

Embodiment 2

[0037] Substantially the same as Example 1, the difference is that the second encapsulation method described in step (6) in Example 1 was not adopted. After 10 days of implementation, the thick-shelled mussels came off obviously, and the shedding rate was 40%, and the remaining individuals The adhesion rate on the frame also reaches more than 80%.

Embodiment 3

[0039] It is basically the same as Example 1, except that the above-mentioned seedling wrapping method is not used, and a bare frame is used. After 10 days of implementation, the surface of the frame is smooth and no large marine organisms have yet adhered.

Abstract

The invention provides a method for constructing a hull reef by means of mytilus coruscus. The method comprises the steps that after juvenile mytilus coruscus is subjected to spat protection in a sea region, the mytilus coruscus is wrapped in a mesh bag made of papyrus, then the mesh bag wrapping the mytilus coruscus spats is put into a seawater pool for temporary culture, and mesh cloth falls off to obtain a spat rope; the spat rope is wound on a hull framework, after knots are tied for the mesh cloth, the spat rope and a hull sink into the sea at the same time, and construction is completed. According to the method, the mytilus coruscus naturally distributed in the East China Sea region is selected as a raw material, the mytilus coruscus is fixed to the artificial components with the help of materials such as flat hemp ropes and the papyrus mesh bag by means of the characteristics of byssus attaching and underwater natural distribution of the mytilus coruscus, and then the artificial components are together transferred and fixed to a three-without ship, so that the ship forms the mytilus coruscus-attached reef in the sea region. An artificial mytilus coruscus propagation technique method is provided, the fishing ship utilization rate is increased, and the time of forming a stable biome on the surface of the fishing ship is shortened.

Description

technical field [0001] The invention relates to a method for multiplying and releasing thick-shelled mussels, in particular to a method for constructing a reef by using thick-shelled mussels, and belongs to the technical field of fishery resource proliferation and maintenance. Background technique [0002] In recent years, due to serious marine environmental pollution and human overfishing, marine biological resources have been extremely declining, and fishery resources are in jeopardy. There was once a dilemma of "no fish in the East China Sea". The current situation of fishery resource decline has attracted widespread attention. In order to protect fishery resources and revitalize the fishing grounds in the East China Sea, Zhejiang Province has launched a special law enforcement action of "one strike and three rectifications" against fisheries. The Zhejiang provincial government dismantled all "three noes" ships involved in fishing. At the same time, in order to reduce env...
