2. Background Under an active spill regime, more fish bypass the dams via spillways than through the collection and monitoring facilities Under an active spill regime, more fish bypass the dams via spillways than through the collection and monitoring facilities Based on PIT tag data from adult salmonids returning to Lower Granite Dam, NOAA Fisheries estimates that only 25-35% of the salmonids passing the Snake River dams are currently detected at the collection and monitoring facilities (Faulkner et al. 2013) Based on PIT tag data from adult salmonids returning to Lower Granite Dam, NOAA Fisheries estimates that only 25-35% of the salmonids passing the Snake River dams are currently detected at the collection and monitoring facilities (Faulkner et al. 2013)

3. Background With funding from BPA, NOAA Fisheries contracted Destron Fearing to develop PIT-tag systems for unmodified and modified spillbays With funding from BPA, NOAA Fisheries contracted Destron Fearing to develop PIT-tag systems for unmodified and modified spillbays Destron Fearing provided the first ogee- type transceiver to test in 2011 Destron Fearing provided the first ogee- type transceiver to test in 2011 Tests compared existing transceivers at the Bonneville Dam corner collector site with the new transceiver Tests compared existing transceivers at the Bonneville Dam corner collector site with the new transceiver

4. The corner-collector PIT-tag system is unique in many ways: 1)it has the largest antenna in the basin 2)it has only one antenna instead of multiple antennas 3)it has a specialized transceiver designed specifically for this site

5. Background Fish tests in 2007, 2009, and 2011 to evaluate new PIT tag models Fish tests in 2007, 2009, and 2011 to evaluate new PIT tag models 2011 we evaluated the prototype ogee transceiver (FS3001) that could detect normal ISO FDX-B tags that are detected in 32 msec as well as tags that can be read in 16 msec 2011 we evaluated the prototype ogee transceiver (FS3001) that could detect normal ISO FDX-B tags that are detected in 32 msec as well as tags that can be read in 16 msec

9. Background In July 2011, Destron Fearing was bought by Allflex Corporation In July 2011, Destron Fearing was bought by Allflex Corporation Allflex put Biomark in charge of all the fisheries work – tags, transceivers, and development work Allflex put Biomark in charge of all the fisheries work – tags, transceivers, and development work Due to the changeover and decision to move installation of the spillway detection system to Lower Granite, development was put on hold Due to the changeover and decision to move installation of the spillway detection system to Lower Granite, development was put on hold

10. Background Upgraded transceivers were tested at Bonneville in 2013, but results were not consistent Upgraded transceivers were tested at Bonneville in 2013, but results were not consistent Biomark’s engineers went back to the lab and came back in 2014 with significant changes to the ogee transceiver Biomark’s engineers went back to the lab and came back in 2014 with significant changes to the ogee transceiver PSMFC testing in Kennewick was conducted and live fish tests at Bonneville occurred in May PSMFC testing in Kennewick was conducted and live fish tests at Bonneville occurred in May Additional testing occurred at Pasco in June Additional testing occurred at Pasco in June

11. Transceiver modifications Biomark modified the layout of the Microprocessor Control Unit (MCU), power supply, receiver, driver, filters, tuning, and terminal board Biomark modified the layout of the Microprocessor Control Unit (MCU), power supply, receiver, driver, filters, tuning, and terminal board The exciter circuit had slight optimizations implemented and the exciter filters were modified and combined into one module The exciter circuit had slight optimizations implemented and the exciter filters were modified and combined into one module The CPU module remained mostly unchanged except for the new phase measurement circuitry The CPU module remained mostly unchanged except for the new phase measurement circuitry Multiple changes were made to the FS3001 firmware, with the most significant changes made to the tuning algorithm Multiple changes were made to the FS3001 firmware, with the most significant changes made to the tuning algorithm
