Conclusions
1. The quality of the acoustic data was very good. Salmon were easily distinguished from eulachon. Flag Point Channel remained suitable for sampling.
2. Flag Point Channel counts provided a clear presence/absence type index and mirrored the general trends in the Miles Lake counts. Trends in the catch efficiency over the study period were similar to those observed in 2002 and 2004. If this pattern is consistent in the future then these data may be used for a more quantitative index.
3. The apparent fish migration speed was similar to previous years. Overall, a 1-day lag between Flag Point Channel and Miles Lake produced good match. Fish appeared to take 1-2 days to travel from the commercial fishery in the Copper River District to Flag Point Channel.
