Abstract: A fluid cutting system of improved configuration provides a high-velocity fluid that is rotated about a first axis (preferably a horizontal axis) on a moving trolley. The trolley is rotationally supported about a second axis (preferably vertical). The trolley travels upon a pair of arc-shaped tracks and is driven by a motor drive. The trolley has a pair of arc-shaped tracks that support the fluid jet nozzle. The fluid nozzle is thus rotatable about two axes, thereby emitting a high-pressure stream of fluid for adjustable cutting. A workpiece positioning frame has a fish section holder that can be elevated or moved laterally with respect to the cutting system.

Abstract: An imaging system includes a method and apparatus for use in processing fish body sections that have been transversely cut. The system uses a frame with a pair of shrouds, each having an interior space that contains an illumination system for illuminating the fish section. A pair of video cameras housed respectively within the shrouds scan opposed flat sides of the fish section to produce images of the respective sides. Screens move behind the fish section in sequential fashion as each camera scans the fish section.
