Figure 3. Mean travel time of smolt release groups as a function of minimum distance travelled.

Travel time estimates are separated by species during the downstream (A) and coastal (B) migration, and separated by wild or hatchery-rearing history during the downstream (C) and coastal migration (D). Coastal travel times include times from ocean entry to the northern Strait of Georgia, Queen Charlotte Strait, or Juan de Fuca Strait lines, so each release group may have up to three points in (B) and (D). Lines show linear regressions fit to mean travel time point estimates for each species or rearing history separately.
