The state of Washington has the largest system of salmon hatcheries in the world, raising more than 200 million juvenile fish at more than 100 state, federal, and tribal facilities each year.

What is a wild steelhead?

Are fish hatcheries good or bad?
While hatcheries are good at producing fish for people to catch,they are not as good at producing fish to survive in the wild, saidReg Reisenbichler, a biologist for the U.S. Geological Survey. To thrive in a hatchery, fish feed aggressively on the top ofthe water, where their food pellets are scattered.
Are hatchery fish considered wild?

What is the difference between fisheries and hatcheries?

What is the Tulalip bubble?
Chinook are caught in 90-120 feet of water during the early summer. This fishery provides some of the earliest opportunity to catch Chinook inside Puget Sound in the late spring/early summer.
What is the difference between wild salmon and hatchery salmon?
For example, hatchery fish rely on hand-feeding, where wild fish must hunt for food. Hatcheries provide artificial shelter for fish versus the natural shelter found in a stream. Compared to hatchery fish, wild fish are usually more successful at surviving the rigors of the natural environment long enough to reproduce.
How many fish hatcheries are there in the US?
70 National Fish Hatcheries across the nation work with states and tribes to produce and distribute fish for recreational and conservation purposes, and provide refuge for endangered species. The hatcheries also provide outdoor opportunities from fishing events and tours to numerous education activities.
What’s going on at the Washington state level of government regarding salmon restoration?

This is an additional harm that may limit the success of threatened or endangered wild populations.
Why do we need hatcheries?
Hatcheries provide the seed for aquaculture and some commercial fisheries. All kinds of fish and shellfish begin life in tanks in a hatchery. A hatchery is a mix of a laboratory and a farm, where fish and shellfish are spawned, then hatched and cared for.
