A marine cage for breeding fish comprises axle means around which the cage is adapted to be revolved. The cage has a grating grill mesh or the like for preventing escape of the fish. At the ends of said axle means are fixed two floats for monitoring the ballasting, when one is full of water, the cage being then completely immersed and said axle means being horizontal and when the said float is empty of water, the cage then being semi-immersed and being capable of turning around said axle means. Inside the cage is fixed a means defining a rudder when the cage is immersed and said axle means is horizontal, which means serves as collection device when the cage is caused to turn slowly around the said axle means when horizontal.
