Summary of 2013 juvenile salmonid acoustic telemetry behavior study at the Bureau of Reclamation Tracy Fish Collection Facility

Cathy Karp, Brandon Wu
Bureau of Reclamation Denver Technical Services Center

In spring 2013, we released acoustically tagged juvenile Chinook salmon (n=69, 136.2 mm mean fork length, late‐fall run Coleman ational Fish Hatchery), juvenile steelhead (n=64, 198.7 mm mean fork length, Mokelumne River Fish Hatchery), and adult striped bass (n=36, 510 mm mean fork length, collected by angling and predator removals) at the Bureau of Reclamation’s Tracy Fish Collection Facility, Tracy, CA, to begin to quantify fish losses to predation and facility structure (louver/bypasses). A system of 21 acoustic telemetry hydrophones were set up upstream, within, and
downstream of the fish facility. Fish were released over a 3 day experimental period in March and May. Flow conditions ranged from 0.6 to 2.9 fps in the primary channel and 2.5 to 2.8 fps in the secondary channel (flows were highest on day 1, intermediate on
day 2 and lowest on day 3), beginning at 7am each day for 24 h. Fish releases were conducted during both day and night conditions (8am, 11am, 2pm, 8pm, 11pm, 2am for salmonids; 8am, 4pm, 12am for striped bass) during each 24 h flow condition. A total of 37 tagged salmonids (28 Chinook salmon, 9 steelhead) were recovered in the holding tanks and exhibited a wide range of behavior. Twenty‐nine fish were lost to predation and louvers (24 Chinook salmon, 5 steelhead). Acoustic telemetry data for the remaining fish are still being analyzed for the time following each 24 study period and include fate categories of swim‐out and non‐participation. The striped bass released into the facility remained while those released in front of the trash rack mostly left (1 as far as Red Bluff on the upper Sacramento River).

Transcript

  • 1. Chinook Salmon and Steelhead Loss Study, Tracy Fish Collection Facility-2013
  • 2. Chinook Salmon and Steelhead Loss Study, Tracy Fish Collection Facility-2013 • 2013 goal: Learn to distinguish Chinook salmon, steelhead, and striped bass telemetry tracks (behavior) at the TFCF to begin to quantify fish survival (loss) and facility efficiency
  • 3. Methods • Acoustically tagged juvenile Chinook salmon and steelhead were released from the trash boom; acoustically tagged adult striped bass were released upstream and downstream of the trash rack; tags implanted 2 days – 1 week prior (included control fish) • Fish released at 6 TOD at 3 study flows: 1, 3, 4/5 JPP pumps, March and May • Fish behavior (including salvage, louver loss, predation, nonparticipation, and swim-out) was determined for the 24 hr period for each specific flow • Facility hydraulic data were recorded throughout 2 study periods and will be analyzed for influence on fish behavior • Facility operated normally with louver cleanings and VC/HT pump changes as needed
  • 4. Fish Data Summary • Released 133 salmonids: • 69 Chinook salmon (x = 136.2 mm FL) • 64 steelhead (x = 198.7mm FL) • Control salmonids held for 7 days • 24 Chinook salmon (x=135.5 mm FL) • 24 steelhead (x=200.5 mm FL) • Released 36 adult striped bass (x = 510 mm FL); 18 in upper channel, 18 in primary channel
  • 5. • 37 salvage (28 CS, 9 SH) • 10 louver loss (7 CS, 3 SH) • 19 predation (17 CS, 2 SH) • 7 nonparticipation • 3 swim-out • 57 unknown (may change with additional processing) Preliminary Fish Fates Fate assignments based on interagency August meeting, on following a tag through time, and on known species behavior (from salvaged fish).
  • 6. 37 Salvaged Fish • Fish collected in holding tank and detected in acoustic tag database • 28 Chinook salmon (of 69 released= 40.6%) • 9 steelhead (of 64 released = 14.1%)
  • 7. 3 salvaged Chinook salmon under range of flows
  • 8. 3 salvaged steelhead under range of flows
  • 9. Participation (Passed Trash Rack) with Flow
  • 10. Chinook salmon (28) Upstream Trashrack (hr) Primary Channel (hr) Secondary Channel and bypasses (hr) Total (hr) Range 0.04 – 13.7 0.01 – 0.2 0.03 – 0.7 0.1 – 14.6 Mean 1.1 0.1 0.1 1.2 SD 3.29 0.05 0.19 3.35 Steelhead (9) Upstream Trashrack (hr) Primary Channel (hr) Secondary Channel and bypasses (hr) Total (hr) Range 0.6 – 9.0 0.3 – 7.4 0.06 – 16.1 0.3 – 24.5 Mean 1.6 1.1 4.5 7.2 SD 2.91 2.42 6.14 7.88 Facility Component Time (hr)
  • 11. Louver losses (10) • Primary channel: 5 fish • 1 Chinook through gap between bays 1 and 2 • 1 Chinook through louvers when secondary channel being cleaned • 2 Chinook and 1 steelhead through louvers unrelated to cleaning • Secondary Channel: 5 fish • 2 steelhead and 3 Chinook through louvers unrelated to cleaning
  • 12. 3407.21 (Primary Louver Loss, 3 JPP)
  • 13. 3771.21 (Secondary Louver Loss, 5 JPP)
  • 14. Predation Losses (19) (as indicated by change in fish’s behavior and detection of a defecated tag within 2-3 days after fish released in MarkTags; predation occurred in both the channel upstream of trash rack (13) and in primary channel (6) • 17 Chinook salmon • 2 Steelhead
  • 15. Confirmation of defecated tag in data processing
  • 16. Size of 19 predated Chinook/steelhead with time to defecation Time to Defecation (from release time) • Chinook salmon (n = 17, mean = 1.71 days, range = 0.7 - 2.8 days) • Steelhead (n = 2, mean = 3.45 day, range 3.3 - 3.6 days)
  • 17. Example of swim-out (blue, ~2.8 days) and non- participation (green,~4.5 days) fates
  • 18. 2 Striped Bass
  • 19. What did we learn from 37 salvaged fish? • Chinook more likely to move into facility at mid/high flows, more variable behavior at lower flow • Steelhead behavior more variable; more upstream movement away from facility, less loss to predation and louvers • Both salmonids generally passed through the primary channel quickly; spent more time in front of trash rack and in bypasses; lots of looping behavior at mid and low flows (and high flows for steelhead)
