Whoever cooks, buys, sells, offers or exposes for sale, gives away, or knowingly delivers, transports, ships, or receives for food purposes any lobster, or similar species of crustacea, or any part thereof, which is uncooked and dead, or which was cooked after it was dead, shall be punished by a fine of not less than $250 nor more than $500, or by imprisonment for not less than 10 nor more than 60 days, or both; provided, however, that it shall not be a violation of this section to cook, buy, sell, offer or expose for sale, give away or knowingly deliver, transport, ship or receive any lobster or part thereof processed for food by a person who has been licensed or certified under this section, as hereinafter provided.
