ARTIFICIAL BIOTOPE Russian patent published in 2003 - IPC

FIELD: fish industry, in particular, mariculture fish farming. SUBSTANCE: artificial biotope has artificial substrate, anchor and float. Artificial substrate is made in the form of rope with fibrous fringed members of synthetic material interwoven therein. Fibrous members of 60-70 mm length are manufactured of material with different modulus of elasticity (E1=800-1,110 MPa and E1=2,500-3,000 MPa) and are interwoven in rope transverse to its base in the ratio of 4:6, respectively. Artificial substrate is arranged at density not in the excess of 64 pcs/sq.m. Fibrous members with modulus of elasticity E1=800-1,110 MPa are made of polypropylene tapes with 5.0-6.0 mm width, and fibrous members with modulus of elasticity E2=2,500-3,000 MPa are made of polyester filaments of 0.5-0.1 mm diameter. Artificial biotope allows biocenosis to be formed, hydrobionts to be reproduced, habitat for living and finishing valuable kinds of fish and invertebrates to be provided. EFFECT: optimal density of settling of hydrobionts, provision for creating wider range of kinds of biocenosis and for obtaining ecologically clean product. 2 cl, 3 dwg
