Oregon Revised Statutes Commercial Fishing and Fisheries § 509.031

(1) It shall be the policy of the State of Oregon that rainbow trout, Oncorhynchus mykiss, including steelhead trout are game fish, and shall be managed to provide recreational angling for the people and to protect wild native stocks. Recognizing that rainbow trout are sometimes intermingled with food fish, the State Fish and Wildlife Commission shall regulate to minimize the incidental catch of rainbow trout that may be taken under subsection (2) of this section by commercial fishing gear, including but not limited to regulations as to season, gear and area.

(2) Any rainbow trout, Oncorhynchus mykiss, including steelhead trout taken as an incidental catch, by any person fishing commercially shall be returned immediately to the water and shall not be bought or sold within the state.

(3) Nothing in this section is intended to affect Indian fishing rights as granted by federal treaties.
