The invention relates to an apparatus for removal of pin bones from fish meat, preferably from a fillet of white fish, comprising a frame for supporting a drive device and a rotatably driven member driven by drive device, the rotatably driven member being provided with engagement means, and a counter pressure element for providing a clamping function between the counter pressure element and the rotatably driven element. The rotatably driven member has a curved convex engagement surface directed towards the fillet and adapted to match the shape of said fillet where the pin bones are located when the fillet is lying on a flat surface.
