Introduction:Puget Sound Chinook salmon have several diverse life history types. In addition to the traditional “ocean-type” life cycle model (river, estuary, sea, return to spawn in freshwater) there are other types including “resident” (river, estuary, and never leave for sea). We were most interested in how habitat use differed between these types and how this may influence the commercial, sport and tribal fisheries.
Summary: Puget Sound fish are on the move! There are different scales of movement including a surprising amount of rapid short-term long distance movement.
There are also patterns of movement patterns within smaller geographic areas (“movers” & sitters).
All this movement expends energy. Why?
Future Plans: Tag more fish and focus more closely on fish size
and time of year tagged. Improve receiver/data recovery and mobile tracking
efforts. Use genetic results to look for hatchery/wild
differences. Look for population differences and “other” life
history types and deviations within the “ocean-type” and “resident” life history examples.
Examine fish movement patterns correlations with tides, diel patterns, water quality, predator/prey interactions and other possible environmental predictors.
