Problems solved by technology

[0003] For the restoration of fishery resources in rivers and lakes, the restoration method cannot be copied in the same way as the restoration of marine fishery resources. Targeted improvements need to be made for specific water bodies and biological groups to meet the urgent needs of freshwater water bodies such as rivers and lakes for resource restoration.

Embodiment 1

[0025] as attached figure 1 As shown, the present invention provides a fishery resource multiplication reef body that is beneficial to the accumulation of organisms. The multiplication reef body includes a reef body main unit 1, an imaging unit 2 and an attracting component 3. The reef body main unit 1 is the main reef body structure. The imaging unit 2 plays the role of presenting images, and the lure part 3 plays the role of luring organisms to approach. The imaging unit 2 and the lure part 3 are both arranged on the reef body main unit 1 to form a complete reef body. The lure part 3 is set In the imaging area of ​​the imaging unit 2, the imaging unit 2 displays the image of the lure part 1, and through the lure part 3 and its image on the imaging unit 2, it is possible to directly and indirectly lure organisms such as fish to approach and enter the proliferating reef body, quickly When the organisms approach, the imaging unit 2 will also display the images of the organisms....

Embodiment 2

[0028] like figure 2 The difference between this embodiment and Embodiment 1 is that the imaging unit 2 is arranged on the side wall surface and / or the upper part of the reef body main unit 1, and is multiplied and adjusted for different organisms from different water layers, so as to promote the attraction of organisms across the water layer .

[0029] Specifically, the imaging unit 2 arranged on the side wall surface of the reef body main unit 1 is a side wall imaging unit 21, which adjusts the fish organisms in the middle and lower layers to approach or enter the interior of the reef body. The imaging unit 2 is the upper imaging part 22, which adjusts the light path in the middle and upper layers, enriches dissolved oxygen in the water body and bait biomass, and attracts fish to swim across the water layer.

[0030] When only the side wall imaging part 21 is set, along with the fluctuation of the water body, the reflective surface of the side wall imaging part 21 can disp...

Embodiment 3

[0035] like figure 2 The difference between this embodiment and the above-mentioned embodiments is that the upper imaging component 22 is connected to the reef main body unit 1 through the elastic connecting component 4, so as to realize the position adjustment of the upper imaging component 22 along with the water body flow and the water depth fluctuation, so as to ensure that it is injected into the water body. The reception effect of light.

[0036] Specifically, the elastic connecting part 4 includes a first connecting seat 41 and a first telescopic member 42. The combination of the first connecting seat 41 and the first telescopic member 42 forms a support structure for the upper imaging part 22 arranged obliquely, and improves the upper imaging part 22. Stable performance when dealing with changes in the state of water flow in the horizontal direction; preferably, two first connection seats 41 are provided, one is fixedly connected to the surface of the upper imaging co...

Abstract

The invention discloses a resource proliferation reef beneficial to fish tending and gathering and a proliferation method. The proliferation reef comprises a reef body unit, an imaging unit and a luring part, wherein the imaging unit is arranged on the side wall surface and / or the upper portion of the reef body unit, an upper imaging part is arranged on the reef body unit through an elastic connecting part, the luring part is arranged on the reef body unit, and the luring part is arranged in an imaging area of the imaging unit. The proliferation reef is suitable for a shallow water area or a water purification area with low biomass and a hypotrophic water body, organisms such as fishes and the like are directly and indirectly lured to approach and enter the proliferation reef through the luring part and the image of the luring part on the imaging unit, the inhabitation, growth and reproduction of the organisms in a proliferation area are facilitated, the biomass and distribution of the organisms are improved and adjusted, an attachment place is provided for adhesive eggs in the water body, and the ecological value of the proliferation reef body is quickly exerted.

Description

technical field [0001] The invention belongs to the technical field of fish resource multiplication, and in particular relates to a resource multiplication reef and a multiplication method that are beneficial to the accumulation of fish. Background technique [0002] Fresh water bodies such as lakes and rivers are shallower than ocean water bodies, and the water body conditions are also significantly different. The living behavior of fish in different water bodies is different. In addition to fish's perception of water flow through the lateral line, their vision, hearing, smell, taste, and touch of mound receptors have an impact on the choice of light and habitat substrate color, and also affect fish burrowing behavior, migratory habits, and diurnal activities. Rhythm and other behavioral characteristics have an impact. Clustering is a common behavioral phenomenon in fish organisms. The behavior of fish clustering is conducive to enhancing communication and reproduction amo...
