Thats awesome Nate. Thanks for sharing that knowledge. It totally makes sense.
Here on the Pacific Coast the largest runs are winter fish, which tend to bolt upstream when the rivers rise dramatically. Perhaps the "estuary" that those fish use is the large volumes of freshwater pumping into the ocean at the river mouth. When they enter the river it only appears they are moving from saltwater to freshwater, when in fact they have already acclimated.
Its a great subject, and just increases my respect for these magnifescent creatures.
