Fig 10. Effects of fish migration date, reach passage time, and mean body temperature on DD accumulation.

Fig 10

Relationships between individual Chinook salmon and steelhead degree day (DD) accumulations in the ~470 rkm migration from release to Lower Granite Dam and their release dates (left) and reach passage time in days (right) in 2000 and 2002. Symbol colors represent mean fish body temperatures (Tmean) over the full reach for spring Chinook salmon (n = 126; squares), summer Chinook salmon (n = 34; circles), fall Chinook salmon (n = 21; triangles), and summer steelhead (n = 75).
