Abstract
Methods and systems for processing fish, such as salmon, are provided which enable filleting of the fish in a particular efficient manner. An example method includes exposing a backbone of a fish from a belly side of the fish, positioning the backbone of the fish on a conveyor device, and conveying the fish with the backbone in contact with the conveyor device. The conveyor may be a spiked chain, and positioning the backbone of the fish on the conveyor device may include engaging the backbone of the fish with the spiked chain such that the fish straddles the spiked chain as the fish is transported. The method may further include cutting the fish from the dorsal side on each of opposing sides of a central plane of the fish to a location adjacent a connection of the pinbones of the fish with the vertebrae of the fish while the fish is conveyed with the backbone in contact with the conveyor device, and subsequently peeling the ribs and ventral spines from fillets of the fish.
