Document Type and Number:
Japanese Patent JP3488365
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a marine movable body movable automatically and efficiently to other sea area while preventing the deterioration of water quality and provide a system for managing the movement of the body.
SOLUTION: To prevent the undesirable influence such as fish disease, a movable culture buoy connected to a net cage 2 for culture is moved after the lapse of a prescribed period (step S24). In this case, the water-quality is detected (step S20), the culturing area free from pollution of water is determined (step S26) by estimating the varying direction of the water pollution and a propelling apparatus 27 is driven to move the buoy to the non-polluted area (steps S28 and S30). The culture buoy is automatically moved to the next culture area while preventing the passage through an area having poor water-quality.
