Straw fish shelter and preparing method thereof

Abstract

The invention discloses a straw fish shelter and a preparing method thereof. The fish shelter comprises a frame and straw arranged on the frame. The frame comprises a cuboid or cubic frame body. The frame body is composed of a plurality of beams and stand columns perpendicularly connected with one another. The straw is rolled on the stand columns. Each stand column is provided with multiple bundles of straw sequentially arrayed in the length direction of the stand column. One end of each bundle of straw is bound to the corresponding stand column, and the other end of the bundle of straw is naturally dispersed around. The nutrients and effective area of the straw are sufficiently used; since one end of each bundle of straw is dispersed in space, the occupied space is large, more algae and shells can be attached, and the unit benefits are improved; meanwhile, due to the structure, the ocean current of an ocean can be changed, the flow velocity of the ocean is reduced in the structure, and therefore the contact time between the fish shelter and the straw is prolonged, and the fish shelter is low in weight, simple in structure and easy to repair.

Description

technical field [0001] The invention relates to the technical field of fish reefs, in particular to a straw fish reef and a preparation method thereof. Background technique [0002] Fishery resources are one of the important sources of protein for human beings. However, due to the toxic effects of marine pollution, the destruction of marine organisms, climate warming, ocean acidification, the increase in fishing pressure in marine fisheries, and the spread of marine pathogenic microorganisms, the global The marine fishery resources of all are in significant decline. At the same time, the structure of fishery resources has also undergone significant changes, from fish species with high trophic levels to low-value and low-trophic level fish species. The proportion of fish keeps decreasing, while the proportion of middle and upper layer fishes, shrimps, crabs and jellyfishes increases year by year. How to conserve fishery resources, maintain their current level, and even impr...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many reports about artificial fish reefs, such as a canvas substrate artificial fish reef and its preparation method applied by the applicant, which is a kind of fish reef prepared by coating and wrapping the outer layer slurry with a canvas tent as the base , this kind of fish reef has the advantages of suitable weight, easy salvage and repair, and can effectively improve the rooting stability of seaweed, and the whole fish reef is not easy to crack and has strong toughness; but the cost of this kind of fish reef is high, which is not conducive to cost control; In addition, the applicant also provided a method for making artificial fish reefs by using the residential frame to be demolished. This method uses the reinforced concrete frame of the residential frame to be demolished to form the matrix. Although it has certain technical effects, the overall weight is heavy and it is not easy Salvage and restoration; in addition, a durable and proliferating artificial fish reef has been provided, mainly using bamboo strips to enhance the connection performance and firmness of the fish reef, but the surface of the bamboo strips is too smooth, which is not conducive to the firmness of the covering material bond
