Ecotype artificial fish reef

Abstract

The invention belongs to the field of artificial fish reefs, and particularly relates to an ecotype artificial fish reef. The ecotype artificial fish reef mainly comprises an upper-half oval shell body and a lower-half oval shell body; the upper-half oval shell body is connected with the lower-half oval shell body through a flexible clamping groove; the top of the upper-half oval shell body is provided with a top end hanging ring; the periphery of the upper portion of the lower-half oval shell body is provided with embedded type pulling rings, the embedded type pulling rings are connected with ropes, the other ends of the ropes are connected with a floating body, and the periphery of the bottom of the lower-half oval shell body is provided with four detachable supporting columns. A semi-sealing shell body structure is adopted by the ecotype artificial fish reef, a good fish gathering effect can be achieved, and breeding can be carried out on the shell body; accordingly, the economic benefit is increased, and the double functions of fish gathering and fish breeding are achieved. By adopting materials around pH 7.9 and arranging a basal body layer which is benefit the attachment and growth of creatures on the surface of the artificial fish reef, the fish gathering effect can be rapidly achieved, the ecological balance effect of a high biomass level is achieved, and the artificial fish reef can be recycled and reused.

Description

technical field [0001] The invention belongs to the field of artificial fish reefs, and in particular relates to an ecological artificial fish reef. Background technique [0002] With the gradual increase of fishing intensity, the scope of marine pollution continues to expand, and the decline of marine fishery resources is becoming more and more serious. As a supplement to marine fishing, mariculture has developed rapidly in recent years. However, the resources and environment in the development of fishery and a series of problems caused by it have become one of the bottlenecks restricting the sustainable development of marine aquaculture and marine fishery in our country. Committing to the research, development and application of marine pastures has become the strategic choice of major marine countries, and it is also one of the main directions of fishery development in developed countries in the world. method. [0003] According to the topographic structure of the seabed...

AI Technical Summary

Problems solved by technology

But, from existing existing artificial fish reef technology, also there are many technical defects

On the one hand, the existing artificial reefs are only for the purpose of gathering fish, but cannot realize the breeding function, and most of them are made of concrete. Due to the large difference between the pH value of the concrete material and the pH value of seawater, it cannot be reefed in a short period of time. internal formation of fish effect

On the other hand, after the current artificial fish reefs are thrown into the seabed, due to the long-term accumulation of silt, most of them sink deep into the seabed, which cannot achieve high-efficiency fish gathering effects, and cannot be recycled.
