Abstract
Fish are oriented by laying them in random arrangement in the central portion of a vibrating trough, the opposite ends of which form passages slightly wider than the widest fish being sorted. Fish move headfirst toward the trough ends, and the movement of fish discharged in single file from such trough ends is accelerated to propel fish past detector means. Such detector means include a radiant-energy source and fish-sorting means responsive to energy from such source operable to deflect fish leaving such source for channeling the fish corresponding to a characteristic detected by the detector. Such characteristic may be sex, length or sidewise orientation. Alternatively, fish can be subjected to detector means for energizing a signal simply to indicate a characteristic of the fish without sorting the fish, such as by placing a fish on an energy-transmitting surface, applying an energy-responsive element to the opposite side of the fish and actuating a signal in response to operation of the energy-responsive element.
