Purpose• Provides direction on the management of non‐native game fish to ensure management actions are consistent with the conservation of native fish and that resources to establish, maintain, or enhance these fisheries are most effectively applied.
• Clarifies Oregon’s management of a very diverse suite of species found across the landscape and provides direction onwhere and when to focus efforts to optimize their recreational use.

Goal
Define how and where to manage non‐native game fish to provide: Recreational angling opportunity; Support important social and economic benefits; Reduce or avoid risk or potential risk to native fish and wildlife.
Implementation likely specific to individual sites, locations, or environments based upon: Native and non‐native fish distributions; Availability and quality of suitable habitat and the importance
of that habitat to native and non‐native fish species.

Key Elements
1. The Non‐Native Game Fish Management Policy applies toall geographic areas within the State’s jurisdiction.
2. Non‐native game fish provide important and valuedrecreational angling opportunities to the people ofOregon. Recreational use of these fisheries has social andeconomic importance throughout the state.

Key Elements3. A changing climate will result in conditions that favor non‐native game fish and as a result, expansion of distribution isanticipated.4. Non‐native gamefish may pose a risk to native fish andwildlife and must be managed to ensure this risk is withinacceptable limits.

Key Elements5. ODFW shall manage non‐native gamefish to meet the following objectives:
a. Optimize recreational use to the benefit of Oregoniansconsistent with conservation of native fish;

Key Elements5. Non‐native game fish are an important resource, ODFW shall manage them to:
b. Provide a variety of recreational anglingopportunities reflecting the diverse resource and adiverse public interest;

Key Elements
6. This policy does not address the on‐going stocking and use of hatchery trout species native to Oregon, such as rainbow and cutthroat trout, and kokanee salmon.
These species may be addressed in other forums through development of Conservation Plans, Hatchery Genetic Management Plans, and through federal Endangered Species Act recovery plans.

Policy Directives
1a. Rivers, Streams, and Natural Lakes:Where non‐native game fish are not present, ODFW will actively manage against the establishment of non‐native game fish.

Policy Directives
1b. Rivers, Streams, and Natural Lakes:
Where non‐native game fish are present and pose a risk to the conservation or recovery of native fish or wildlife, or would be detrimental to the reestablishment of extirpated native fish or wildlife populations, ODFW will actively manage against the expansion of non‐native game fish.
At some specific locations, this may include efforts to reduce or remove non‐native game fish depending on the degree of conservation risk, management options and resources available, and likelihood of success.

Policy Directives
1c. Rivers, Streams, and Natural Lakes:
Where the impact of non‐native game fish on native fish or wildlife is negligible or native fish or wildlife have been extirpated and the natural ecosystem functions have been altered such that reestablishment of native fish populations is unlikely, ODFW will manage for recreational opportunityof non‐native game fish.

Policy Directives
1d. Ponds, Lakes, and Reservoirs:If populations of non‐native and native game fish combine to provide a recreational fishery (mixed stock fishery), ODFW may continue to manage for the full suite of species.

Policy Directives
1e. Ponds, Lakes, and Reservoirs:If a population of non‐native game fish is present and the population is detrimental to the quality of the fishery, ODFW may actively manage by removing or reducing the non‐native population causing the problem to reestablish the desired recreational fishery.

Policy Directives
1f. In Waterbodies with Significantly Altered Habitat:
ODFW will continue to establish, maintain, or enhance a desired recreational fishery for non‐native game fish as long as the non‐native game fish population and associated fishery do not pose a conservation risk to native species.

Policy Directives
2. In response to an illegal introduction:
a. Attempt to eradicate the species if it is feasible andpractical;
b. If the species cannot be eradicated and presents aconservation risk, actively manage to reduce its presenceor influence;
c. If the species cannot be eradicated and presents minimalconservation risk, manage to prevent or minimize itspopulation growth and range expansion, but may alsomanage the non‐native game fish to provide recreationalopportunity at that location.
