A mechanical system has been developed to automatically separate flat fish from round fish by utilizing their differences in projected area and aerodynamic properties. A continuous stream of mixed fish is moved along a belt conveyor at a rapid rate, and upon discharge each fish is subjected to a blast of high velocity air. Differences in shape and ratio of projected area to weight of flat fish and round fish are sufficient to alter their trajectories and therefore enable their separation. Experimental results indicate that the system is a practical method to sort fish by shape, either at sea or ashore.
