An apparatus and method for removing pin bones from fish fillets includes at least one pin bone removal device and a conveying device designed to convey the fish fillets past the at least one pin bone removal device. The pin bone removal device includes a rotationally driven profiled roller having a counter-bearing element forming a clamping gap, the roller and the counter-bearing element being designed to grasp the pin bones in the clamping gap by clamping and to remove the bones from the fish fillets by applying tensile force. The counter-bearing element and the roller are designed to be controllably moved with respect to each other by a controller.

A revolutionized tuna process according to this invention generally comprising the steps of thawing of frozen tuna, de-heading and degutting, fileting, de-skinning, cleaning of the de-skinned tuna filet, pre-cooking, cooling, packing of the cleaned and pre-cooked tuna loin, and sterilizing the packed tuna loin or freezing the tuna loin. Not only does the process according to this invention reduces the energy utilization by half, it also significantly reduces the time required for cooking and cooling. Therefore, the whole processing time is significantly reduced from at least 8.0 hours in the conventional process to less than 30 minutes.

This disclosure relates to a reciprocating saw blade for preparing fish. The reciprocating saw blade can comprise a blade and a wing. The blade can attach to a reciprocating blade. The blade can comprise a tip, a cutting edge, a spine, and a heel. The cutting edge can have continuous wavy serrations formed through a tooth from a plurality of teeth. The tip can form an inward curve towards the cutting edge. The cutting edge can be at one side of the blade while the spine can be at the opposite side. The spine can form an equidistant parallel line with the cutting edge. The heel can be at the rear end of the cutting edge. The wing can be at the rear end of the blade and can have an orifice and a prong. The orifice can be compatible to a quick-release mechanism of the reciprocating blade.

This disclosure relates to a reciprocating saw blade for filleting and preparing fish. The reciprocating saw blade can comprise a blade and a wing. The blade can be attachable to a reciprocating blade. The blade can comprise a tip, a spine, a cutting edge and a heel. The spine can be at one side of the blade. The spine can have a concave form from the tip up to the middle side edge section of the blade and can form a straight edge from the middle section up to the rear side edge section of the blade. The cutting edge can have a continuous set of serrations formed through a tooth from a plurality of teeth. The cutting edge can comprise a grind that divides the spine and the cutting edge. The grind can taper from the middle section of the blade to the cutting edge.
