1 Guide to Half- and Full-duplex RFid: Lessons Learned Tracking Bull Trout in the Upper Willamette Since 2001 Vince Tranquilli Fish Research and Monitoring Program

2 Objectives What is new since 2001 Why we choose HDX How to build antennas Prepare for Demo in Park

3 23 mm long HDX tag NEW Prototype tag Images by Warren Leach Image by Warren Leach

4 < Juvenile Tagging Size Fork length (mm) Number of bull trout

5 Captive Rearing Program

6 Release tagged fish smaller size = less time in artificial environment earlier = when food is available

7 New Since 2001 Smaller tag Better tuning module

8 Antenna Tuning Oregon RFid Inductance (uh) TI-RFid Capacitance (nf)

9 New Since 2001 Prototype small tag Better tuning module Interactive data logger

13 Objectives What is new since 2001 Why we choose HDX

14 Why we choose HDX? Cost-effective (readers/materials) Low power Easy to use - no effect water level - no effect vibrations 10 mi. 20 km

15 Why we choose HDX? Bull trout Long-lived species Complex life history

16 South Fork McKenzie River Adult escapement? Repeat spawning frequency? Juvenile-to-adult survival? Juveniles downstream movement? When are fish entrained? Which route through the dam? If recovered below dam and we move them back over the dam do they survive? When do fish leave the reservoir? What areas of the reservoir do they use? 2 mi. 5 km

17 Upper Middle Fork Willamette River Where are fish spawning? Site fidelity? Repeat spawning frequency? Where is mortality occurring? 2 mi. 5 km

18 Why we chose HDX? Antennas are simple to build Build to meet site/projectspecific requirements When it breaks we can fix it Not overly invested in any one site (low impact)

21 How to build antennas Swim-through antennas Antennas for use in culverts Larger antennas (Dam sites) Fish attraction (Reservoirs) Mobile antennas Flat-plate antennas

22 Stream-width Swim-through 1 loop antennas Up to 30 long 12 volt 12 gauge wire Max. depth ~ 3.2 ft.

23 Stream-width Swim-through 1 loop antennas Larger antennas: 18 volt Up to 30 long x 3.2 volt x 3 gauge wire 190 x 18 Max. depth ~ 3.2 ft.

24 Stream Profile Max. separation distance 1.1 m (depth)

25 Rock Vector flow

28 Materials we no longer use

29 Culverts

30 3 loops 8 gauge m diameter 3 ¼ tube m 48

31 9 x 9 2 loops 12 gauge

32 6 9 2 loops 12 gauge ¾-1-¼ space

33 Common Problem Rebar in concrete reduces performance

34 Solution

35 Fish Attractor Station Fish attraction (light, bait, habitat) Add video for untagged fish 8 gauge speaker wire Variable size, # of loops, spacing

36 Fish Attraction Station

37 5 loops 18 gauge wire Mobile HDX antennas

38 Mobile FDX/HDX System Optimal Tag Orientation ( 90 ) 23 mm HDX = 56 cm 12 mm FDX = 37 cm 8.5 mm FDX = 20 cm

39 Swim-thru vs. Swim-over antennas Map detection field in cross-sectional view Antenna orientation matters

40 Tag orientation also matters 90 45

41 Tag orientation also matters

42 Swim-over antenna

51 Juveniles: > 100 mm in length body cavity Immature to Adult: > 270 mm in length dorsal sinus

52 23 mm long HDX tag Fish > 27 cm fork length

53 Park Demo Concepts Tag orientation (angle) Swim-through/flat plate/mobile Tag speed relative to EM field size Wire sizing and materials Antenna tuning Power requirements
