PURPOSE: To obtain a culturing place device for recovering the dead body of fish and unused feed from a marine basket for a fish culturing place. CONSTITUTION: The device is extended downward from the vertical wall of the marine basket and is provided with a net whose bottom is terminated by an opening part and which is tapered to inside. A funnel-shaped collecting member is fixed to the opening part of the net and is provided with an inlet end part inside of the net and an outlet end part outside of the net. One end of a pipe is connected to the outlet end part of the collecting member and the other end part is connected to a dehydrating box. An air defuser is serially connected with the pipe at the lower position of a water surface and is provided with plural holes for injecting air to water in the pipe. By injecting air from the defuser, a flow is generated in water in the pipe to remove the dead bodies of fish and the excreta of fish from the collecting member by this water flow. Until unused feed pellet appears where water is discharged to a dehydrating box, the feed pellet is supplied. |
