FISH COLLECTING CASE FOR ARTIFICIAL FISH GATHERING BANK AND FISH COLLECTING PANEL PRODUCED BY USING THE CASE

摘要

PURPOSE:To facilitate the formation of a panel with fish-collecting mesh cases and the attachment of the panel to an artificial fish gathering bank and to improve the durability of the case. CONSTITUTION:A stopper 2 is passed through a water-passing mesh member 1 containing oyster shell, etc., in the mesh member. The end of the mesh member is inserted into a steel channel 3, the stopper ends 21, 21 are bonded to the channel 3 and a cement mortar 4 is filled in the channel 3 around the stopper 2. The case may be produced, in addition to the above, e.g. by inserting the end of the mesh member into the opened end of a steel pipe or inserting the end of the net member into the opened end of a plastic pipe and thrusting a bolt to the pipe. These fish collecting cases are welded or bolted with each other to form a panel.
