Sockeye metrics 0412_med

 

The Cedar River Sockeye Salmon Hatchery at Landsburg, Washington, produces sockeye salmon for the Lake Washington system. Sockeye salmon from the Cedar River are spawned at the hatchery. The embryos are incubated for about 4 months. They are then able to swim into fry ponds where they are kept for up to two weeks. The fry are then released into the Cedar River. The releases are timed to occur during the swim up of naturally-produced fry in the river. The capacity of the hatchery is 34 million fry, but the number of fry produced is related to the availability of adult sockeye for broodstock.
