(A) Any vessel used in aid of taking blue crabs by trap or transporting live blue crabs taken by traps for commercial purposes must display crab trap identification numbers assigned by the department as authorized in Article 5 of this chapter. The numbers must be displayed permanently and conspicuously on the outside of the hull on both the port and starboard sides of the vessel near midships. Individual letters and numerals must be no less than eight inches in height and six inches in width and of a color contrasting that of the hull. An unobstructed circle no less than eight inches in diameter, in a contrasting color must be displayed next to the trap identification number. The circle must consist of any one or two colors, other than black or yellow, which match the color or color combination utilized on the buoys of the crab traps being used. If two colors are used, each must cover one-half of the circle. Colors must be of such hue and brilliance as to be easily distinguished and seen.

The department may approve and require crab fishermen to register color choices.

(B) A person who violates this section is guilty of a misdemeanor and, upon conviction, must be fined not less than twenty-five dollars nor more than five hundred dollars or imprisoned for not more than thirty days.
