Link to our animator to see the return migration of adult sockeye and Chinook salmon tagged in Cook Inlet, Alaska, 2013. These fish were double-tagged with internal acoustic tags and external disk tags. We tracked their movements with an acoustic array, but some fish have supplementary final locations supplied when their disk tags were recovered by the fishery. The data were used to identify species-specific differences in migration depth or other movement patterns that could assist with stock management.
David Welch testified at the Cohen Commission (Commission of Inquiry into the Decline of Sockeye Salmon in the Fraser River) for two and half days in early July. A transcript of the testimony can be found here.
