1323 - Temperature Lethal - 941 934
Details
- Pink salmon yolk-sac fry had wide temperature tolerance and could withstand
wide fluctuations in temperature if embryos were incubated at ³5°C during
early developmental stages. Embryos incubated early at >10.5°C suffered a
higher rate of mortality and deformities, and grew more slowly.

1318 - Water Motion Optimum 934 -
Depth Limit 15 cm
Details
An acceptable pink salmon minimal spawning depth depends on the amount of
flow fluctuation. In rivers with relatively stable flows during the
incubation period (base flow ³50% average annual daily flows, and high flows
£2x that average), the minimal safe spawning depth is expected to be ³15 cm.
