Research toolbox Monitoring systems Tradeoffs Radiotelemetry Acoustic telemetry HD PIT tags Tradeoffs Different tools for different questions Complimentary Tag life limitations Handling issues
Monitoring system tradeoffs Active radiotelemetry Good for tailraces, fishways, tributaries Best current tool for dam passage metrics External antenna may contribute to tag effects Acoustic telemetry Good for deep water No external antenna Limited application in turbulent water with entrained air
Monitoring system tradeoffs Passive HDX-PIT tags Unlimited tag life: useful for overwinter evaluation Fewer known tag effects Limited application for fine-scale fishway evaluations
