Embodiment 1

[0034]A fish-collecting type fish reef for increasing cultivation, the main body of the fish reef is two cuboid frames 1 stacked up and down, the two cuboid frames 1 are equal in length, width and height, and the bottom surface of the upper cuboid and the top surface of the lower cuboid Sharing one side, the height of the lower cuboid frame protrudes downward from the bottom surface so that the overall frame forms upper, middle and lower three-layer spaces in the vertical direction; among them, the side and top surfaces of the upper cuboid frame are two-way geogrid 2, and the inner side of the side Diagonal lines are provided with oblique ribs b 5, two diagonal lines inside the top surface are provided with oblique ribs a 9, the center of the top surface is provided with a circular through hole 3, and the four corners of the top surface are provided with U-shaped pull rings 4 , the bottom surface of the upper cuboid is a grid net 15, and the edge of the grid net 15 is provided ...

Embodiment 2

[0036] This fish reef is suitable for 5-30m deep seabed stocking. After the welding and installation on the work platform is completed, after the link rope 7 connected to the top of the cast iron conical cover 16 passes through the stainless steel circular through hole 3 on the upper surface, the other end is connected to a plastic material with a buoyancy slightly greater than the gravity of the conical iron cover 16. Floating ball 8, fish reef is put into the seabed with winch then, at this moment, small cone channel 20 vertically unfolds, and conical iron cover 16 is positioned at the top of stainless steel support bar 10, guarantees that the fish of trapping passes through on the truncated cone frame The bottom surface enters the interior of the reef.

[0037] Before fish reef is put into the seabed for a certain period of time and is ready to be harvested, first cut off the link rope 7 between the plastic floating ball 8 and the conical iron cover 16, and allow the conica...

Embodiment 3

[0039] Depend on Figure 1-4 Shown, a kind of fish collection type increases culture fish reef, the outside is the cube frame that the steel bar of diameter 25mm is welded, is divided into upper, middle and lower three layers. The length, width and height of the upper floor are 6m, 6m and 2m respectively. The height of the middle layer is 20-30cm. The height of the lower layer is 30cm.

[0040] The outer four sides and the top of the upper layer of the fish-collecting type increased fish reef are two-way geogrids made of polyacrylamide (PAM) anti-aging materials, and the two-way geogrids are tied to the steel frame with plastic cable ties. Together. A diagonal tie bar is welded in a diagonal direction on the outside of each side of the upper frame of the fish-collecting-type fish-raising fish reef, and a circular stainless steel through-hole with a diameter of 10cm is provided at the center of the top of the fish-collecting-type fish breeding fish reef. Diagonal stays are ...

Abstract

The invention discloses a fish attracting type culture and proliferation fish shelter and a use method thereof, and belongs to the technical field of fish culture and proliferation. The fish attracting type culture and proliferation fish shelter is composed of a cuboid frame divided into an upper layer and a lower layer, wherein a cone frame is arranged in the upper layer, a tapered iron cover isarranged at the top end of the cone frame, the tapered iron cover is connected with a floating ball outside the frame through a hinge rope, the inner portion of the cone frame is provided with a plurality of small cone passages, the side face of the lower layer is provided with a plurality of waste cages, and the bottom of the lower layer is provided with a bracket. The fish attracting type culture and proliferation fish shelter can provide an excellent habitat for fishes and has an attracting effect. The fish shelter can not only provide a survival habitat environment for the fishes, but alsocan achieve the purpose of selective fishing of the attracted fishes, and can also rise and fall through lifting equipment to facilitate movement.

Description

technical field [0001] The invention relates to a fish collection-type multi-culture fish reef and a method for using the same, belonging to the technical field of fish multi-culture. Background technique [0002] Artificial fish reef is a structure artificially set up in the sea. Its purpose is to improve the ecological environment of the sea area, create a good environment for marine organisms to inhabit, and provide fish with a suitable environment for reproduction, growth, shelter, and bait, so as to achieve protection and multiplication. purpose of fishery resources. [0003] At present, the mainstream fish reefs are concrete component reefs. Most of these fish reefs have single functions and can restore natural resources after being put into the seabed. However, the controllability is poor, and the monitoring and management of fish reefs is difficult; It is difficult to catch the fish in the pool; after a long time on the reef, it is easy to silt up and bury the pheno...
