Conclusions

•
Since 2011, both Transient (69) and Resident (2) White Sturgeon were
detected at PD7.
Transient sturgeon were recorded relatively few times annually with
short duration but some individuals were detected in multiple years.
Resident sturgeon were recorded several thousand times annually and
were detected in multiple years.
Transient sturgeon were detected passing through a wide range of coils
from the terminus of the pile to the near shore (2014 data).
Resident sturgeon were detected on a variety of coils but records were
greatly biased towards Coil no. 6 perpendicular to the pile dike and
about mid-way towards the shoreline (2014 data).
Resident sturgeon appear to ‘mil’ and pass both left and right from Coil
no. 06. It was rare between 21 May and 3 Nov. for either resident
sturgeon to be absent from PD7 for > 1d.

Recommendations
• Establish PD7 as a permanent PIT-tag interrogation site in
the estuary
• Establish secondary sites to increase sample size and
understand patchiness of fish distributions
• Continue adaption of flexible antenna design to mobile
applications
• Target species
• Adult and jack salmonids (all species and runs) for travel time and survival to
Bonneville or other upstream dams
• Juvenile salmonids for thalweg to shoreline migration comparison with the
trawl system in thalweg
• Sturgeon, Northern Pike Minnow, Cutthroat, and others (shad?, lamprey?,
eulachon? if tagged and released into the /Columbia River Basin
