To efficiently sort many fishes by the kind through the use of the device of remarkably simple structure by sorting a fishes by both their widths and heights to specify the kind of fish from both of them.
The kind of the fish is sorted by both its width and height to specify the kind of fish from both of them. To put it in the concrete, in order to sort a horse mackerel or a mackerel, e.g. the fishes of 15 to 80mm in width captured by a round haul net are sorted by 5mm pitch and then fishes in areas A to L separated by the width according to a graph are sorted by their heights by sorting all in the area A of a width 15 to 20mm to be horse mackerels, fishes of more than 37mm in height to be horse mackerels and fish less than this to be mackerels in the area B of a width 20 to 25mm, fished of more than 43mm in the height to be horse mackerels and fishes less than this to be mackerels in an area C, and the like. In addition a body width sorting device is provided with a sorting unit arranged with plural rollers parallel and the interval between the rollers of the sorting unit of a low stage is gradually widened so as to gradually allow large fish to pass through between the rollers of the sorting unit.
