Description

Technical Field

[0001] The utility model belongs to the field of artificial fish reefs, and in particular relates to a prefabricated component of a tetrahedral pyramid artificial fish reef with asymmetric staggered openings. Background Art

[0002] Artificial reefs, as an artificial structure that promotes fish reproduction, growth, foraging and shelter, play an important role in creating biological habitats, improving the aquatic ecological environment, and protecting and increasing fish resources. They were initially used in marine ranch construction and have been gradually introduced into inland waters in recent years. However, their application in mountain rivers is not common.

[0003] Mountain rivers have narrow bodies, steep banks, large riverbed gradients, rapid currents, and drastic water level rises and falls. The environment suitable for fish to rest, hide, and forage is limited. In order to adapt to the characteristics of mountain rivers and promote the proliferation of fish resources, this application proposes a prefabricated component for artificial fish reefs with asymmetric staggered openings in a four-sided pyramid.
