MATERIAL FOR COLLECTING WATER ANIMALS, SMALL LIFE-FEEDING PLACE, AND MAN-MADE GATHERING PLACE FOR FISH

摘要

PURPOSE:To obtain a small life-feeding place suitable for protecting and breeding benthos or artificial fish-gathering place by using a strip of artificial lawn structure or a three-dimensionally entangling structure of synthetic fibers. CONSTITUTION:A strip of artificial lawn structure measuring 10-200mm pile length and 10-50cm width or another strip of a three-dimensionally entangled structure made of synthetic fibers in which the crossing points are adhered so that the final void volume reaches 80-99% is directly used in the form of a sheet. Or plural strips are combined to form a polyhedron or much more strips are combined to form a three-dimensional structure. Or these strips are set to ropes or columns or a three-dimensional frame made of a synthetic resin.
