Artificial gathering-place for fish
专利汇可以提供Artificial gathering-place for fish专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain an artificial fish gathering-place capable of secularly restoring surfaces into novel ones, killing shellfish larvae, etc., and producing remarkable effects as improvement in fishing ground, by providing wheels on side edges of plural perforated plate units, closely adhering and superposing the plate units so that plate units are movable on rails 4 through the above- mentioned wheels.
CONSTITUTION: Fisheries plants are adhered to the surface of all the superposed plate units 1 and one thereof is moved along rails 4 when the first year with the best adhesion ratio passes. Novel surfaces which have hiterto been closely adhered are exposed. Fisheries plants are allowed to newly grow thick on the surfaces and then collected. The above-mentioned operation can be repeated to annually expect adhesion ratio in the first year. Already 'withered' surface are closely adhered to 'withered' surfaces of other plate units 1 by the movement of the plate units 1. As a result, roots of fisheries plants or shellfish larvae, etc., are secularly killed. Thereby remarkable effects can be produced on improvement in fishing ground by using this fish gathering-place.
