TABLE 1
| Group of | 30d | 60d | 90d | 120d | 150d | 180d |
| |
43.6 | 48.5 | 51.4 | 53.9 | 56.7 | 58.4 |
| Example 2 | 41.8 | 46.8 | 49.2 | 51.9 | 54.5 | 56.9 |

As can be seen from the experimental data in table 1, the compressive strength of the fish reef prepared according to the present invention does not decrease with the passage of time but gradually increases when the fish reef is immersed in river water, and thus the stability and durability of the fish reef in river water are excellent and the service life thereof is prolonged.
Test example 2
In the test, factory sewage containing Cu, Cr, Hg, Mn, Pb, Zn and Cd heavy metal ions is poured into 5 small pools respectively, the volume of the sewage poured into each small pool is equal, the content of Cu, Cr, Hg, Mn, Pb, Zn and Cd in the water body of each small pool is detected, the artificial fish reef prepared by the scheme of the embodiment 1-5 is placed into each small pool respectively, after the artificial fish reef is soaked for 30 days, the content of Cu, Cr, Hg, Mn, Pb, Zn and Cd in the water body of each small pool is detected, and the reduction percentage of the heavy metal content in the water body is calculated according to the difference between the front heavy metal content and the rear heavy metal content, so that the result is shown in the following table 2;
TABLE 2
As can be seen from the test results in table 2, the artificial fish reef of the present invention can effectively adsorb heavy metal ions in a water body, wherein the artificial fish reef of example 5 has the best adsorption performance.
Test example 3
