摘要：

Details are provided for the design and operation of an inexpensive box for grading fish less than 80 mm in body length. The base of the box consists of two slotted screens, one on top of the other, which can be offset to alter the slot width. This configuration offers infinite adjustment up to the maximum width of the slots.
