METHOD OF THE FLOATING CULTIVATION OF BIVALVE LARVAE, APPARATUS FOR CONTROLLING THE SAME AND APPARATUS FOR THE FLOATING CULTIVATION OF BIVALVE LARVAE

摘要

A method of the floating cultivation of bivalve larvae, wherein two or more cultivation water tanks having cultivation water pooled therein are provided to allow the selective use of cultivation water tanks A and B; bivalve larvae are cultivated in one cultivation water tank A for a predetermined period of time; the cultivation water in one cultivation water tank is increased from the start of the cultivation; then the floating larvae are transferred into the other cultivation water tank B together with the thus increased cultivation water via a larvae-transporting pathway; and the thus transported floating larvae are cultivated in the othercultivation water tank. After the preceding transportation, the inside of the former cultivation water tank is washed with washing units (7, 15). These working operations are automatically conducted after the passage of a predetermined time.
