At the Council’s May 19, 2009 request, the ISRP reviewed a response received from the Columbia River Inter-Tribal Fish Commission (CRITFC) regarding the ISRP's December 15, 2008 review of the Columbia River Fish Accord proposal titled Sea Lion Predation Rate Estimation and Non-lethal Hazing (200800400). In the December 2008 review, the ISRP found that the proposal did not provide sufficient information for a technical review and thus did not meet scientific review criteria (see attachment).

The ISRP requested a response on several issues including non-lethal hazing (proposal objective 1), video monitoring (objective 2b), and acoustic telemetry (objective 2a). CRITFC sent a response covering each of these issues.

Recommendation: Meets scientific review criteria in part (qualified)

• Objective 1 – does not meet scientific review criteria
• Objective 2a, Acoustic Telemetry – meets scientific review criteria (qualified)
  Qualification: The ISRP recommends collaboration with the ongoing BPA-funded Pacific Ocean Shelf Tracking (POST) project (2003-114-00) and the U.S. Army Corps of Engineers-funded acoustic tracking projects.
• Objective 2b, Video Monitoring – meets scientific review criteria (qualified)
  Qualification: the ISRP recommends limiting the trial to one location, specifically at Bonneville Dam, where visual observations are being made by the Corps and ground-truthing is possible.
