APOSTICHOPUS JAPONICUS SUBMARINE CULTURE METHOD USING ARTIFICIAL APOSTICHOPUS JAPONICUS REEFS

摘要

Artificial apostichopus japonicus reefs and an apostichopus japonicus submarine culture method using the artificial apostichopus japonicus reefs. The artificial apostichopus japonicus reef comprises a first reef plate (1) and a second reef plate (2) made of a common concrete material; the first reef plate (1) and the second reef plate (2) are connected in an inverted-V shape; the first reef plate (1) and the second reef plate (2) are uniformly provided with holes and are integrally formed. The method comprises the steps of: 1) splicing multiple artificial apostichopus japonicus reefs into an apostichopus japonicus reef facility group in an inverted-W shape, wherein the apostichopus japonicus reef facility groups are arranged in parallel in the shape of the Chinese character "彡" on the seabed, a space between adjacent two apostichopus japonicus reef facility groups is 30-50 m, and an included angle between a free end of the artificial apostichopus japonicus reef at the outermost side of the apostichopus japonicus reef facility group and a current direction is 10-25°; 2) placing, according to the density of 7-15/square meter, apostichopus japonicus seedlings into a sea area where the artificial apostichopus japonicus reefs are located for proliferation; and 3) harvesting apostichopus japonicus after 12-36 months. The artificial apostichopus japonicus reefs and the method can greatly enhance the suitable seedling placement density, improve the survival rate of proliferation, and shorten the culture period.
