(b) Notwithstanding the provisions of subdivision (a) of this section, black marlin (Makaira Indica) may be imported into this state for the purpose of processing (manufacturing) a product commonly known as fish cakes for human consumption. All black marlin (Makaira Indica) imported into this state must be in an identifiable condition and accompanied by a bill of lading, showing the name of the consignor, the consignee, and the weight or number of fish shipped.
