MARINE ALGA ADHESION BASE

摘要

PROBLEM TO BE SOLVED: To make sea urchin and marine alga coexist while protecting early immatures of marine alga from eating damage of sea urchin. SOLUTION: The marine alga adhesion base 1 has a base material 2 and a large number of linear bodies 3. The lower end part 4 of the bases material 2 is fixed on the sea bottom 5. The base material 2 has a vertically long and slender flexible sheetlike state. The linear bodies 3 are projected and extended outside from the base material 2. The base material 2 has 5-10cm width and 20-40cm length. The heights H1 of the linear bodies are 2-30 mm and the mutual interval L1 of the linear bodies is 3-30mm and the diameter of the linear body is 100d-2mmϕ. COPYRIGHT: (C)2007,JPO&INPIT
