Fry emergence and gravel permeability of chinook (Oncorhynchus tshawytscha) and coho salmon (Oncorhynchus kisutch) spawning redds in Prairie Creek, Humboldt County, California
Sparkman MD. 1997. Fry emergence and gravel permeability of chinook (Oncorhynchus tshawytscha) and coho salmon (Oncorhynchus kisutch) spawning redds in Prairie Creek, Humboldt County, California. Humboldt State University
This project examined the emergence of salmonid fry by trapping young fish as they emerged from 5 redds in Prairie Creek (Redwood National Park). Four of the redds were of chinook salmon, and the fifth of coho. The author discusses emergence timing, and relates gravel permeability to survival of the fry, confirming an expected higher survival rate in redds with greater permeability. The study is connected with excess sediment added to Prairie Creek during the Highway 101 Bypass construction; it shows 'the lasting effects of the sediments on chinook and coho salmon fry emergence.' The 14 appendices include data on fry numbers and lengths, and various information related to permeability.
