A pin bone removal device that provides a plurality of fixed members arranged substantially in side-by-side orientation. The invention also comprises a plurality of moveable members also substantially arranged in a side-by-side orientation. In one aspect, the fixed members and moveable members collectively form a stack of members in which a moveable member is positioned adjacent each fixed member. In this aspect, a linear drive is operatively connected to each of the moveable members and is configured to cause oscillating movement of each moveable member to cause the moveable members to contact the adjacent fixed member. This movement causes pinch points to be created and released between the fixed and moveable members. As the fillet of fish is moved along the stack of members, the pin bones are caught at each pinch point and then released.
