It is discharged via 40. By the inward flow of the culture water, plankton and other organic matter flocs in the culture water are blocked by the net 30 stretched around the cylindrical machine frame 22, and the culture water discharged from the drain pipe 40 is discharged. Is not flowed in. However, plankton and the like riding on the inward flow of the culture water in the outer region A tend to adhere to the outer peripheral surface of the net 30.

Plankton and the like, which tend to adhere to the outer peripheral surface of the net 30, are separated from the net 30 by the action of the flow generated by the rotation of the blade member 36 and the flexible plate 38.
The attachment to the net 30 can be prevented in advance. Moreover, since the flow is extremely slow, it does not damage the plankton.
