Apparatus for removing pin bones from fish fillets includes at least one pin bone removal device and a conveying device configured to convey the fish fillets past the at least one pin bone removal device. The pin bone removal device utilizes a rotationally driven profiled roller and a counter-bearing element. A clamping gap is formed between the rotationally driven profiled roller and the counter-bearing element. A control is configured to control a relative movement between the rotationally driven profiled roller and the counter-bearing element. The pin bone removal device is configured to grasp and remove the pin bones via tensile force from the fish fillets in the clamping gap.
