A part (11) of the tube, located above the upper valve (12), is filled with fish eggs. By opening the upper valve (12) the fish eggs are mixed with the water in the container (13). When the lower valve (14) is opened the fish eggs and the water flow out through at least one orifice hole (22) in the point (15).
