METHOD OF A ROCK FISHING REEF

摘要

An eco-friendly rock fish reef and a manufacturing method for the same are provided to be eco-friendly and to be used permanently for the increase in marine products and restoration of ecosystem. Penetrating fish/shellfish recesses(11) having a diameter of more than 40-60cm are formed at the lower end of an eco-friendly artificial fishing reef. Fish/shellfish recesses(12) having a depth of more than 30-90cm are formed at the middle end and the upper end of the eco-friendly artificial fishing reef. The artificial reef is made by processing a rock having a porosity of 10-50%. The fish/shellfish recess is large in its middle portion, and becomes smaller as it goes toward its upper end to have two or more stages. The fish/shellfish recesses are arranged in zigzag.
