1. A machine for filleting fish, the machine comprising:
filleting stations,
a conveying system configured to convey a sequence of fish in a downstream direction through the filleting stations while each fish of the sequence of fish is oriented with a back side of the fish facing in an upwards direction and with right and left sides of the fish on opposite sides of a vertical centre plane, and
at least one width detection mechanism placed at an upstream location relative to the filleting stations and configured for detecting a width of the fish,
wherein at least one of the filleting stations is a plane cut filleting station comprising:
a first cutting blade arranged on one side of the vertical centre plane and configured for cutting the fish during rotation of the first cutting blade about a first rotation axis,
a second cutting blade arranged on the opposite side of the vertical centre plane and configured for cutting the fish during rotation of the second cutting blade about a second rotation axis, and
a gap control structure configured based on the detected width of the fish to change a gap between the first cutting blade and the second cutting blade while the fish is being cut.
