METHOD FOR RAISING FILTER-FEEDING BIVALVE, SYSTEM FOR RAISING THE FILTER-FEEDING BIVALVE, METHOD FOR PURIFYING BRACKISH WATER USING THE FILTER-FEEDING BIVALVE, AND SYSTEM FOR PURIFYING THE BRACKISH WATER USING THE FILTER-FEEDING BIVALVE

摘要

PPROBLEM TO BE SOLVED: To provide a method for efficiently raising a filter-feeding bivalve, using a system for raising the filter-feeding bivalve and, especially, capable of preventing the filter-feeding bivalve from suffering weight loss in summer, and to provide a method for efficiently purifying brackish water, using a system for purifying the brackish water capable of effectively exhibiting a water quality-purifying function inherent in the filter-feeding bivalve. PSOLUTION: In this method, a Japanese corbicula clam is raised by flowing the brackish water through a water channel made of concrete or covered with a water barrier sheet. It is preferable that sand is not laid on the water channel as a bottom material, a depth of a deposit deposited in the water channel is made to be not more than several cm, and a depth of the water in the water channel is made to be shallow. The brackish water is effectively purified, by applying the method to the system for purifying the brackish water. PCOPYRIGHT: (C)2007,JPO&INPIT
