CRAWL FOR OFFSHORE CULTURE

摘要

PURPOSE:To obtain a readily movable crawl for offshore culture, having strength sufficient for withstanding ordinary ocean waves and tidal currents, etc., at a low cost, by connecting many float body modules to form a polygonal float body. CONSTITUTION:The ends of plural (6 in the figure) columnar float body modules 1 are mutually and foldably connected to form a polygonal float body. Bracing levers 6 are provided between the central float body 5 at the center of this polygon and each float body module 1 to fix the polygon. Nets 3 are fixed to the sides or undersurface of the polygonal float body to form the aimed crawl.
