  1. Some observations on interpreting fish tagging costs – and model development updates Bill Jaeger IEAB & Oregon State University March 19, 2013

  2. Current model version: tag/detections for juvenile & adult dam passage, SAR (no harvest recovery, escapement detections) – with 100 detections required at major dams • tag/detections for juvenile & adult dam passage • SAR • no harvest recovery, escapement detections yet • 100 detections required to estimate survival between major dams

  3. How can we interpret data on PIT tag costs per tag, or per detection, or per unique detection? For this model result, “binding” detection requirements = 7,200 But total tags inserted are 2.4 million, at a cost of $9.4 million .

  4. “Activity” cost estimates – current numbers in IEAB programming model

  5. Harvest tagging: Cost tradeoff between marking, sampling, recovering (data)

  6. Harvest tagging: Cost tradeoff between marking, sampling, recovering (data) – part II
