A B S T R A C T In a method for the vaccination of fishes, especially trout and salmon fry, one has aimed at achieving a rapid and lenient vaccination of each single fish. A machine for carrying out the method is to be reliable, of high capacity in relation to its size and capable of ensuring precision vaccination of the fish. For these objects the method is characterized in that the fish first is anaesthetized in a vessel (1) containing anaesthetic-admised water. From the vessel, the fish - as it is anaesthetized and as a consequence thereof sinks to the bottom - is conveyed upwards and transferred to an unidirectional device (4). The unidirectional device (4) ensures that further conveyed fish is carried head first in the feeding direction. From the unidirectional device (4), the fish, via a edgewise-turner (6) ensuring turning of the fish edgewise, is carried into a vaccination device (7) having injection means for individually vaccination of the fish. A machine for carrying out this method comprises an anaesthetizing vessel (1), a conveyor (2) for conveying anaesthetized fish from the vessel (1) to an unidirectional device (4), wherefrom the fish, via an edgewise-turner (6), is carried into a vaccination chamber provided with vaccination means for the vaccination of the fishes individually.
