Commercial fish farming involves many steps between producers and end users of aquaculture products. One important step in this process is the sorting or grading of live fish. Grading allows the producer to maximize profits when prices vary with fish size.
Large fish mixed with smaller ones can affect the appearance of a shipment of fish.
