Abstract
A prototype machine is described for sorting fish by species and size at sea. The fish are transported along a conveyor underneath a video c amera whose images are processed by a computer to obtain shape and col our descriptors. The fish are then diverted into the appropriate bin u sing computer controlled pneumatic arms. Species sorting accuracies at both Rockall and the North Sea of 99% were achieved for flatfish and round fish at a throughput of 40 fish/min.
