**Sympatric O. mykiss model: pilot run**

Notes:

Well lets take a look at some of the pilot model runs. This scenario plots observed vs predicted for the time period of 1992 through 2005. Emperical estimates of smolt to adult return rates specific to the outmigrant years were input into the models corresponding migrant years. There seems to be a slight delayed response from the model as indicated by the crest in 96/97 and the again in 2004. The model also seems to moderate the year to year variability as indicated from the sequence from 1992 to 2000. This is probably attributed to the annual fluctuations in the environmental conditions affecting freshwater production and survival at a much finer resolution than the model captures. These fluctuations in environmental conditions also impact the proportion of progeny embarking on the different life history pathways derived from both fidelity and hybrid crosses.
