The Washington Department of Fish and Wildlife (WDFW) is responsible for managing the state's fish and wildlife resources and establishing basic rules and regulations governing the time, place, manner, and methods used to harvest fish and wildlife.  Game fish are fish that may not be fished except by rule of the Fish and Wildlife Commission.  Game fish are classified in statute and include several species, including catfish, trout, bass, and walleye.

A Warm Water Game Fish Enhancement Program (enhancement program) was established in WDFW in 1996.  The enhancement program is designed to increase the opportunities to fish for warm water game fish including bass, catfish, crappie, walleye, and tiger musky.  The enhancement program is designed to use a practical applied approach to increase warm water fishing.  A portion of each freshwater and combination fishing license fee is dedicated for the development of warm water pond and lake habitat, culture of warm water game fish, improvement of warm water fish habitat, management of warm water fish populations, and other practical activities that will improve warm water fishing.  WDFW must actively involve organized fish clubs when developing the enhancement program.

The Governor issued an executive order in 2018 convening the Southern Resident Killer Whale Task Force (task force).  The task force was directed to identify, prioritize, and support implementing a plan to address threats to Southern Resident orca whales including prey availability, contaminants, and disturbance from vessel noise.  During the 2019 legislative session, legislation was enacted directing the Fish and Wildlife Commission to implement task force recommendations and reduce predation by non-native game fish on salmonids.

The Fish and Wildlife Commission must adopt rules limiting the bag limits for warm water game fish to no more than five fish per day in nonanadromous waters to maintain a healthy and vibrant long-term fishery.
