INSTALLATION FOR MARINE AQUACULTURE IN INLAND SEA UTILIZING SAND FOUNDATION

摘要

PROBLEM TO BE SOLVED: To produce unpolluted and clean fishes and shellfishes in a marine aquaculture crawl by using filtered sea water and providing a facility for inhibiting the sea water from being contaminated through the fish culture.;SOLUTION: An inland sea marine aquiculture farm is created in a sand dune area and filtrated sea water is introduced into the farm thereby a culture pond is made independent from the surroundings. An apparatus for removing the feed residue caused by feeding and excretion is installed to retain a clean sea water environment. A fractured stones net filter is placed on the sea bottom of sand foundation so that a certain amount of spaces may be retained and the water in the gap spaces between the crashed stones is sucked. Introduced filtered sea water is pumped up and sent to an adjustment reservoir under a certain pressure and the water temperature, various germs, dissolved oxygen, or the like, are examined and controlled. In addition, an apparatus for carrying out the treatment of the feed residue and the excretion is set up and the cleaning operations are carried out at regular intervals without fail.;COPYRIGHT: (C)2005,JPO&NCIPI
