At least one marking disposed on said elongated body between the two ends. A predetermined distance exists between each marking and one of said ends. Each predetermined distance corresponds to the legal minimum length of at least one species of fish. Protrusions extend from the elongated body of the planar element. A predetermined distance exists between each protrusion and one of the ends of the planar element. The predetermined distance corresponds to the minimum acceptable length of either a crustacean or a shellfish.
