Ohio Revised Code Title XV. Conservation of Natural Resources § 1533.64

Fish lawfully confined in a net, or by a device authorized by law, are the property of the owner or person operating the net or other device. No person other than the owner or person in control of the net or other device shall take or catch from it or possess a fish that is or has been so confined unless the person so taking, catching, or possessing the fish has been authorized in writing to do so by the owner or person in control of the net or other device. Each fish taken from and each fish had in possession that was taken from any net or other device legally operated in any of the waters of this state by any person other than the owner or the owner's agent operating the net or other device constitutes a separate offense.

No person shall fail to comply with this section or a division rule adopted pursuant thereto.
