STEEL-BASED FISH REEF WITH REDUCED FISH NET CATCHING

摘要

PURPOSE: Provided is a steel-based fish reef which reduces net catching by adopting triangular prism and triangular pyramid typed elements to the fish reef. CONSTITUTION: The steel-based fish reef has a main body comprising at least 6 sides. On the surfaces of the main body, triangular prism structures are placed, which width gets shorter toward the upper end from the lower part. At the corners around the main body, trigonal pyramid typed elements are disposed to connect the triangular prism structures.
