Figure 2.9. Model-averaged survival rates (+/- 1SE) of adult Fraser River sockeye salmon to reach natal watersheds in relation to encountered Fraser River temperature. Results are based on > 800 fish that were carrying transmitters, which were inserted in the ocean from 2002-2007. Figure adapted from Martins et al. (2011). 91
Figure 2.10. Relationship for Early summer and Summer runs between en route loss as a percent of the total run and the mean 31-day temperature experienced by a run in a given year for „thermally stressful years‟ (e.g. years when mean temperatures > 18 o C; 8 of 17 years from 1992 to 2008). (R 2 = 0.50, P < 0.01). Data source: DFO Fraser River Environmental Watch Program. 92
