Abstract: In a method for vaccinating fishes, the fishes are first anaesthetized in a vessel (1) containing anaesthetic-admixed water. From the vessel, the fishes-as they are anaesthetized and as a consequence thereof sink to the bottom-are conveyed upwards anad transferred to an unidirectional device (4). The unidirectional device (4) ensures that the further conveyed fishes are carried head first in a feeding direction. From the unidirectional device (4), the fishes are individually carried, via an edgewise-turner (6) ensuring turning of the fishes edgewise, into a vaccination device (7) having injection means for individual vaccination of each fish. A machine for carrying out this method comprises a conveyor (2) for conveying anaesthetized fishes from the vessel (1) to the unidirectional device (4), wherefrom the fishes are individually carried, via the edgewise-turner (6), into a vaccination chamber (15) provided with vaccination devices for vaccination of the fishes individually.

Abstract: Machines for loading fish in boxes having a first conveyor supporting a series of transport containers and serving to transfer fish sideways while each is disposed in its respective transport container in a preselected position with the heads of fish in adjacent containers facing in opposite directions and the bellies directed upwards. The fish transfer is made from one or a pair of cooperating feeders to a second conveyor having a series of catch devices adapted to engage their respective fish and effect transfer thereof to an associated box for deposition therein. The two conveyors are arranged to be driven at a uniform speed in a continuous circulatory movement. The relative disposition of the conveyors is such that local regions of the paths of movement of the catch devices and the transport containers coincide enabling the catch devices to engage their respective fish in the transport containers one after the other.
