A newly developed gauge for measuring carapace widths of crabs is described. Tests showed that it was accurate to ± 0.5 mm, and its broad jaws enabled maximum carapace width to be measured more consistently than with vernier calipers. In addition, it was noncorrodible and faster and easier to use than calipers. Two years of intensive field use have demonstrated its suitability for measuring crabs.
