Abstract

A method and apparatus for processing flat fish is disclosed. The fish (5) are placed on a conveyor (1) and transported on a conveying surface (1.1) over an array of photosensing elements (3.4) which generate light absorbtion signals as the fish is advanced. These signals are sent to a computer, which determines the contour of the fish using information regarding the conveyor speed and computes cutting control signals using pre-programmed proportionality factors relating to the fish species. The cutting line control signals are sent to a cutting apparatus (4). As the advanced fish arrives at the cutting apparatus, two rotary knives (4.1) cut into the dorsal and ventral sides of the fish in response to the control signals to remove the dorsal fin together with a strip of fatty tissue (5.12) from one edge of the fish and the internal organs, the anal fin and the ventral strip of fatty tissue (5.11) from the other edge of the fish.
