PIT-tag Systems Consist of
Tags Transceivers Antennas
2001: BE ISO tags FS1001A 2’ x 6’
2008: SST ISO tags FS1001M 3’ x 20’first 9-mm tag Corner collector 17’ x 17’
2005: ST ISO tags FS1001M (multiplexing) 2.5’ x 12’
Future: 16-msec tags New multiplexing transceiver ogee-passby, 5’ x 25’ or 5’ x 50’(2012) 12-mm HDX Replacement dam transceiver (2020) larger / more antennas shorter/thinner tags Spillway-Ogee and New TI-HDX
great 9-mm tag
1999: 400-kHz tags 400-kHz 12” pipe
2010: SST-1 ISO tags no new Destron 4’ x 25’ 13-mm HDX Allflex-low power, FDX&HDX 3’ x 10’
better 9-mm tag
Tags
BPA – New tag contract for 3 sizes of PIT tags
Received 18 tag models from different vendors in December 2011
PSMFC and NOAA Fisheries evaluated the tags with laboratory, field, and fish tests
12-mm contract went to the same Destron SST-1 tag (now being sold as Biomark tag)
9-mm tag 9-mm contract went to RFID Solutions S.L. (detection rate was 54% in the BCC system vs 12% for best Destron 9-mm)
Tag costs reduced with new contract
23-mm contract went to Biomark
16-msec tags (7-9% higher detection at BCC)
TagsAdditional new PIT tags
New 12-mm HDX tags (improved over 13-mm prototype)
Slender 8-mm x 1.25-mm tags (12-mm: 30% volume and 24% weight at .024g)
Individual antennas
Monitor or 4 antennas
Large Full-flow antennas 62.8 95.9Smaller juvenile antennas 95.6 99-100
Average Detection Rate
Many small tags now available(smallest 7-mm x 1.25-mm tags had disappointing performance)
Tag or Tagging Effects
12.5-mm tags have been shown in several studies to negatively impact SARs
Do smaller tags have less of a negative effect?
NOAA Fisheries is designing an experiment to evaluate this in Alaska with its higher SARs
Lost or shed tags / higher mortality (if so how much higher)
Future for Tags
I think we will see anti-collision firmware that will make it possible to detect multiple tags that are in an antenna’s field simultaneously.
9-mm tags to replace 12.3-mm tags as standard size?
Ability to kill or temporarily disable tags (e.g., collecting tag data from avian predator populations)
Transceivers
Biomark (nee Destron Fearing)
Ogee transceiver
2020 transceiver – replacement for transceivers at dams, ISO
New multiplexing transceiver
On-going Developments
NMFS and Allflex Improving system performance for low-powered Allflex board
Spillway Detection - Ogee transceiver
Powerful - capable of creating field 4-5’ deep in passby mode
Possible replacement for corner- collector transceiver (i.e., it will be able to operate very large single antennas)
Can detect the 16-msec tags
25-35% of tagged fish returning have no juvenile passage info
2020 transceiver
Designed to replace the FS1001J, FS1001A, and FS1001AB at the mainstem dam sites with a single transceiver model
Auto tuning
Diagnostics needed to help PSMFC maintain its high operational standards
Several communication ports (ethernet, fiber optic, USB)
ISO transceiver, so reads both FDX and HDX
Will be installed and tested in 2012
Currently will not work for smaller antennas
New multiplexing transceiver
Auto tuning
Substantially better read range Can sync master controllers
Same power consumption as MUX for 6 antennas Up to 12 antennas
NOAA Fisheries will be testing final prototypes during first week of April
New multiplexing transceiver
Biomark
Texas Instrument
New handheld or portable reader
Transceivers
Future Developments
Low cost multiplexing transceiver
New reader for HDX tags
Antennas
As in the past, once we have new transceivers, we will learn how to push them to maximize antenna size and learn how to use them for new applications.
For example, new multiplexing transceiver will require less of an air gap in its antennas than the MUX.
Tests of a 50’ long antenna with prototype ACN transceiver
(new meaning to it’s in the back of the truck)
Emerging and Future Applications
Lower Granite Dam
Spillway Detection
Goal is to install for 2014
TSW into Bay 2 as backup for RSW in Bay 1
Lower Granite Dam’s ogee is very different from Ice Harbor Dam’s
Tag collisions are a big issue for spillway detection
Detection rate is a big unknown
Antenna read range want 48-60”
Emerging and Future Applications
30 ft
11 ft
Support cable anchored on the shore and fixed to the piling. Antennas will be clipped to this for suspension and orientation.
15 to 20ft
4 ftCable straps, wood screws or ratchet straps fix the PVC knuckles to the piling
C-shaped aluminum bar is secured to the piling and, with rope straps, prevents side to side movement of antenna during tidal changes
Flow
Pelican case to house transceiver, batteries and radio link and solar panel for continuous power supply
Emerging and Future Applications
Juvenile lamprey
Cougar Dam
Purpose is Flood Control
Many lack fish passageways
Emerging and Future Applications
Willamette Basin
Computer Programs
M4 program for interrogation data
More incorporation of meta data into fisheries database(s)
Better web-based tools that allow for more complicated and faster analyses
M4 program for performing separation-by-code
