The multiple reach migration model estimates the average travel time of tagged fish from release points to several downstream observation sites. The fish were fitted with Passive Integrated Transponder (PIT) tags that yield instaneous passage timing information for individual fish at detection sites (colored dots in map below). By comparing modeled travel times to observed travel times, model parameters are calibrated for a variety of juvenile salmonid stocks. For each stock analyzed, the data are compared to a sequence of models incorporating increasingly complex behavior. In this way we can determine the appropriate level of model complexity for predicting individual stocks.
In the map above, release sites are designated in blue text and observation sites are the red circles. Each study group has its own pattern of observations. Not all observation sites are active for each group. To go to the results for a particular stock, click on the appropriate release site in the map above.
