Primary Assay — Crayfish
Aggression / Dominance Hierarchy
Procambarus clarkii
Crayfish establish linear dominance hierarchies through ritualized agonistic encounters involving chelae displays, body raises, and wrestling. Hierarchy formation provides a model for studying serotonergic modulation of social behavior.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Procambarus clarkii.
| Parameter | Unit | Description |
|---|---|---|
| Approach frequency | events/min | Agonistic contact initiation |
| Chelae display duration | s | Weapon presentation |
| Fight escalation level | 1-5 scale | Threat → contact → wrestling → retreat |
| Dominance establishment time | min | Time to stable hierarchy |
