At present, the construction of artificial fish reefs is widely carried out at home and abroad to repair the habitats and fisheries of offshore marine organisms, and a better effect is achieved. The conventional artificial fish reef often has the following problems in the use process: the flow velocity of the seawater in the fish reef is too high, so that nutrient substances gathered at the place are taken away, and the fish gathering effect is reduced; the artificial fish reef has large integral mass, is easy to sink in muddy seabed, and loses the functions of protecting and increasing the amount of harvested fish after the fish reef is buried. Meanwhile, the seabed environment is relatively single, various elements capable of promoting the growth of algae are often lacked, and the regulation by natural force is difficult. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.

Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 and 2: an artificial fish reef capable of improving marine environment comprises a base plate 1 serving as a foundation, wherein a fish reef body is arranged on the base plate 1, the whole fish reef body is in a regular quadrangular frustum pyramid shape and consists of four side plates 2 and a top plate 3, the side plates 2 are sequentially marked as a, b, c and d, a first round hole 4 is formed in the side plates a and b 2, the circle center of the first round hole 4 coincides with the centroid of the side plates a and b 2, two second round holes 5 are formed in the side plates c and d 2, the circle centers of the two second round holes 5 do not coincide with the centroids of the side plates c and d 2, the radius of the first round hole 4 is 1.5-2 times of the radius of the second round hole 5, and the artificial fish reef can not flow out from another direction rapidly when seawater flows into the fish reef body through the first round hole 4 or the second round hole 5 by the structural design, so that a turbulent flow is formed in the internal part of the fish reef body, the retention of nutrient substances is facilitated;

The bottom of the side plate 2 is also provided with a rectangular sand discharge notch 6, after the fish reef body is used for a period of time, a part of sand inevitably enters the fish reef body, the sand can settle to the bottom of the fish reef body under the action of gravity, and a part of sand can be discharged through the sand discharge notch 6 under the action of water flow, so that the fish reef body is prevented from sinking due to excessive sand accumulation;
