An Investigation into the Poor Survival of an Endangered Coho Salmon Population
Figure 2
Mark-recapture survival estimates for Thompson River steelhead trout, Chinook and coho salmon smolts.
Survival was estimated during the downstream migration from 2004–2006, by tag type. Standard error bars are shown. The smolts were of wild (W), hatchery (H) or unknown (U) origin, from the Coldwater River (CR), Deadman River (DR), Nicola River (NR) and Spius Creek (SC) populations. The same model assumptions were used for Chinook and steelhead as for coho [46].
