The commissioner may require that any person that prepares, stores, handles or distributes catfish or fish for retail sale maintain a verifiable record-keeping audit trail that permits the commissioner to verify compliance with this law and any regulations promulgated hereunder.
Presumably, any restaurant, or retailer, in this day and age, has sufficient record-keeping already that adding the information from the distributor about the origin of the seafood sold will not create any problems for them. If not, then I’m not sure how they would keep up with their costs and income even without this requirement.
