Primary Assay — Sea Lamprey
Rheotaxis
Petromyzon marinus
Sea lampreys orient and maintain position against water current during upstream migration. Upstream orientation, station-keeping success, and current speed thresholds measure rheotactic performance.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Petromyzon marinus.
| Parameter | Unit | Description |
|---|---|---|
| Upstream orientation | % time | Body alignment to current |
| Station-keeping success | % time at position | Holding against flow |
| Current speed threshold | cm/s | Maximum navigable flow |
