Commercial fishing Fish and shellfish harvested in Washington waters make their way to markets around the world. The Washington Department of Fish and Wildlife (WDFW) oversees regulations and management for a variety of fisheries, working to ensure a robust commercial fishing and shellfishing industry for the future. Lost fishing gear - both commercial and recreational - sits on the seafloor, gets caught on rocks, and floats in the water column. Lost gear can remain in the marine environment for years, harming habitats and continuing to catch fish and invertebrates. Please report sightings of lost recreational and commercial fishing gear. Buying a commercial fishing license in Oregon is an option for residents and non residents of the state who would like to use their fishing expertise for profit. Commercial fishing licenses are required for all commercial fishing practices in Oregon and are issued by the Oregon Department of Fish and Wildlife.
