Description
Technical field
The present invention relates to fish shelter technical fields, and in particular to a kind of straw fish shelter and preparation method thereof.
Background technique
Fishery resources are important one of the protein sources of the mankind, but due to the toxic action of marine pollution, marine organisms
It is destroyed, climate warming, Ocean acidification, sea fishery the fishing increase of pressure, the diffusion of ocean pathogenic microorganisms etc.
Reason, global marine fishery resources are significantly failing.At the same time, fishery resources structure is also significantly changed, by
High trophic levels fingerling is converted to low value and low nutrition level fingerling, is embodied in fished species and is constantly substituted, in catches
Juvenile fish ratio constantly increases, and demersal fishes proportion is constantly reduced, in, epipelagic fish and shrimp, crab and jellyfish class ratio year by year
Increase.How fishery resources are conserved, maintain its existing level, in addition improve fishery resources level become one it is global
The problem of.Aquafarm is settling mode one of of the mankind to this problem, and aquafarm can be understood as a kind of novel fishing
Industry aquaculture system, the corresponding mode of different waters is different, the main placement for passing through subbottom structure object (referring mainly to artificial marine habitat),
Change the abiotic environments such as shadow effect, flow field effect, the sound effect in local sea area, is built for part marine organisms good
Habitat is inhabited, the place multiplied and lived is provided, is finally reached the purpose of the living marine resources such as protection, proliferation fish.It presses
The type of purpose classification, artificial marine habitat can be divided into: trap fish shelter, proliferation fish shelter, oviposition reef, sparing of undersized fish reef and algal reef etc..
It, need to be according to the spy of different waters since there are difference for the marine environment such as the ocean current of different waters, substrate and aquafarm target
Point and target need to be arranged the artificial marine habitat of different configuration type.
Currently, have been reported that about artificial marine habitat also more, a kind of canvas substrate artificial marine habitat and its system applied such as applicant
Preparation Method is a kind of a kind of fish shelter that coating package outer layer slurry preparation is carried out using canvas tent as matrix, this fish shelter weight
Properly, it salvages, repair and be easy, and can also effectively improve seaweed takes root the whole not easy to crack, toughness of stability and fish shelter
Strong advantage；But this fish shelter cost is high, is unfavorable for the control of cost；In addition, applicant also provided a kind of utilization
The method of house frame manufacture artificial marine habitat to be torn open, this reinforced concrete frame using house frame to be torn open constitute base
Body, although there is certain technical effect, overall weight weight is not easy to salvage and repair；In addition, also provided it is a kind of it is durable and
The artificial marine habitat of proliferation mainly is used to enhance the switching performance and firmness of fish shelter using bamboo cane, but bamboo cane surface is excessively
It is smooth, it is unfavorable for the secure bond of cladding material.
Straw is a kind of common agricultural crop straw, and yield is very big, it is general gather in after paddy just straw filled or
For feed or manufacture paper etc.；Straw nutrition rich in fact, and it is very easy to degradation, if by itself and Artificial Fish
Reef combines, and for manufacturing aquafarm, has boundless prospect.
Summary of the invention
The present invention is directed to the above-mentioned deficiency of the prior art, and provide a kind of nutritional ingredient for making full use of straw and straw has
Imitate area, after being scattered due to boling rice straw one end space diffusion, realize take up space it is big so that more seaweed, shellfish
Attachment, unit benefit improve；This structure can also change the ocean current of ocean simultaneously, and the flow velocity of ocean is slack-off in the structure, from
And the time of contact with straw is improved, in addition, nutriment can be obtained more by complicated channel, increase flow route
Nutrition, the minute protrusions that not will cause environmental pollution and its surface spikes shape conducive to degradation are more conducive to cohering for covering material
And hanging, and it is capable of providing that light quality, structure are simple, conducive to the straw fish shelter and preparation method thereof of reparation.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention are as follows: a kind of straw fish shelter, the fish shelter include frame
Frame and the straw being set on frame, the frame include the frame body of cuboid or square figure, frame body by
Several crossbeams being mutually connected vertically and column are constituted；The straw is rolled on column, is provided in each column
More bundle straw are simultaneously sequentially arranged along the length direction of column, and more bundle equal one end of straw are tied on column, the other end is natural
Surrounding is scattered.
The present invention uses straw as the main material of fish shelter for the first time, straw due to rich in nutrition content, be conducive to degradation not
It will cause environmental pollution, more natural, nutritious growing environment, the more conducively life of marine organisms can be provided for marine organisms
Long and attachment, and this is simple and light, facilitates the picking and reparation of shellfish seaweed etc.；In addition, above structure of the present invention can
To make full use of the effective area of straw, due to straw be it is bundled rolling and one end scatter after space realize diffusion, realize
