Wild Puget Sound Steelhead: Less Than 3% of Historical Abundance
A recent study by WFC scientists Nick Gayeski and Bill McMillan, along with consulting fishery biologist Pat Trotter, looks at the historical abundance of Puget Sound winter steelhead from 1895, the year in which the peak commercial catch of steelhead occurred, and compares these data to more recent numbers. Their results show that current abundance is likely only 1%–4% of what it was prior to the turn of the 20th century and that loss of habitat alone does not explain these dramatic reductions.
A 2007 study by NOAA Fisheries Service reported similar estimates of historical steelhead abundance in Puget Sound. Status Review of Puget Sound Steelhead (Oncorhynchus mykiss) June 2007.
