The utility model discloses it can increase the attachment area of alga to have optimized bellied structure to the guiding gutter can be with the drainage of assaulting of wave, and remain the small biology in the wave.

Further preferably, the side wall of the first protrusion and the side wall of the second protrusion are both inclined surfaces. Easy to adhere to algae to produce various small organisms and trap various natural baits around the bulge.

Further preferably, the interior of the fish reef body is provided with a hollow channel with two communicated ends. The hollow channel can generate small vortex, so that the fish can inhabit in the fish reef more easily.

In the figure: 1. a fish reef body; 2. a first patch; 3. a second patch; 4. a first protrusion; 5. a second protrusion.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1-2, the overlength type irregular convex artificial fish reef comprises a fish reef body 1, wherein the fish reef body is of a prism structure, a plurality of triangular patches are attached to the surface of the fish reef body, the surfaces of the patches are rough surfaces, the thicknesses of the patches are gradually reduced from the bottom edge of the triangle to the vertex angle of the triangle, the patches comprise a plurality of first patches 2 and a plurality of second patches 3, and the area of the first patches is larger than that of the second patches; at least three first patches in the plurality of first patches are provided with first bulges 4, the bottoms of the first bulges are distributed along the outer contour of the first patches, the tops of the first bulges are quadrilateral planes, at least three second patches in the plurality of second patches are provided with second bulges 5, the bottoms of the second bulges are distributed along the outer contour of the second patches, and the tops of the second bulges are quadrilateral planes; the protruding direction of the first protrusion is staggered with the protruding direction of the second protrusion.

The utility model discloses a thereby the surface that has increased different thickness at the fish reef forms irregular shape on the surface that makes the fish reef, when piling up in a large number in the breakwater periphery, can regard as first protective screen to thereby the arch formation back of the body vortex of irregular shape has been increased in the fish reef main part, makes small-size zooplankton concentrate on the fish reef periphery, strengthens its function of keeping away from the enemy, and promotes the natural bait hyperplasia. The tops of the protrusions are designed to be flat so that the force of the waves is slowed down. Meanwhile, due to the complex structure, the fish reef cluster can form a labyrinth to confuse enemy fishes eating larval and juvenile fishes, and the field survival rate of the juvenile fishes is improved, so that the supplementary generation survival rate is increased.

Further preferably, the length of the fish reef body is 5-10 meters, the width of the fish reef body is 3-7 meters, and the inclination angle of the first protrusion and the inclination angle of the second protrusion are both 22.5 degrees. The overlength type design is to let the paster continuous for this paster adhesion surface can be attached to alga or other sessile benthos, forms the algae farm more easily.

Further preferably, the length of the fish reef body is 7 meters, and the width of the fish reef body is 5 meters.

Further preferably, the fish reef body may have a triangular prism structure, a quadrangular prism structure or a pentagonal prism structure. The fish reef main body structure with different sizes can be selected according to different requirements.

Further preferably, a first diversion trench is arranged between two adjacent first convex side walls, the first diversion trench is communicated with the top of the first convex side wall, a second diversion trench is arranged between two adjacent second convex side walls, the second diversion trench is communicated with the top of the second convex side wall, and the first convex side wall and the second convex side wall are rough surfaces. The utility model discloses it can increase the attachment area of alga to have optimized bellied structure to the guiding gutter can be with the drainage of assaulting of wave, and remain the small biology in the wave.

Further preferably, the side wall of the first protrusion and the side wall of the second protrusion are both inclined surfaces. The algae is easy to attach to generate various small organisms, and various natural baits are trapped around the bulges.

Further preferably, a hollow channel with two communicated ends is arranged in the fish reef body. The hollow channel can generate small vortex, so that the fish can inhabit in the fish reef more easily.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
