Combined artificial fish reef

Abstract

The invention discloses a combined artificial fish reef. The combined artificial fish reef comprises a halfpace-shaped reef body, middle-layer floating reef bodies and an upper-layer floating reef body. The halfpace-shaped reef body comprises a base, a halfpace reef fixed to the base, and an adhering substance. The adhering substance is arranged on the side face of the halfpace reef, and bottom anchor rings are embedded into the positions, close to the four corners of the bottom of the halfpace reef, of the base. The middle-layer floating reef bodies comprise floating rope frames, floating balls fixed to the four corners of the floating rope frames, and seedling ropes. The seedling ropes are arranged in the floating rope frames, and the four corners of the floating rope frames are connected with the corresponding bottom anchor rings through floating rope frame fixing ropes. The upper-layer floating reef body comprises a floating pipe frame and a top web curtain. The top web curtain is arranged in the floating pipe frame, and the four corners of the floating pipe frame are connected with the corresponding bottom anchor rings through top frame fixing ropes. The stereoscopic hierarchical structure can create a full-water-layer algae growth environment and provide places for life and inhabiting of fishes on different water layers; the halfpace reef can form upward flow, bottom nutritional substances are conveyed to the middle layer and the upper layer, and bait is provided for fishes on the middle layer and the upper layer.

Description

technical field [0001] The invention relates to an artificial fish reef, in particular to a combined artificial fish reef in which a terraced concrete fish reef unit at the bottom is combined with floating rope frame kelp seedling rope multiplication in the middle and upper part and seaweed net curtain. Background technique [0002] As the main component of restoring marine ecological resources and building marine ranches, artificial reefs have various structures, such as box-shaped, triangular, frame-shaped, etc., and their materials are mainly reinforced concrete. Due to the limitation of construction, transportation and delivery equipment, the size and weight of reef components should not be too large. After launching, these reefs are mostly bottom reefs. After a long time, the siltation and settlement of the reef itself will make it difficult to guarantee the durability and sustainable ecological effect of the reef.

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the limitation of artificial fish reef structure in the prior art, its flow state effect is limited to the trapping effect of pelagic fish, and the sedimentation and settlement of reef body itself after a long time is difficult to ensure The durability of the reef and the shortcomings of the continuous ecological effect provide a combined artificial fish reef
