Behavioral Tracking for African Turquoise Killifish
Nothobranchius furzeri
ConductVision delivers automated tracking of killifish aging-related locomotor decline, learning changes, and sleep patterns. Quantify age-dependent behavioral deterioration and intervention effects in Nothobranchius furzeri.
Why African Turquoise Killifish in Behavioral Research
The African turquoise killifish (Nothobranchius furzeri) is the shortest-lived vertebrate that can be bred in captivity, with a natural lifespan of 4-6 months. This makes them the ideal model for studying age-related behavioral decline in a vertebrate system within a compressed timeframe. Locomotor deterioration, cognitive decline, social disengagement, and sleep disruption mirror mammalian aging patterns, enabling rapid screening of anti-aging interventions.

What We Measure in African Turquoise Killifish
Validated assays with quantitative parameter tracking for Nothobranchius furzeri.
Killifish show progressive locomotor decline mirroring mammalian aging. Total distance, mean velocity, and immobility tracked across the lifespan provide a compressed vertebrate aging model for intervention screening.
| Parameter | Unit | Description |
|---|---|---|
| Total distance per age | mm/10min | Age-dependent decline |
| Mean velocity per age | mm/s | Speed reduction |
| Immobility increase | %/week | Progressive inactivity |
| Activity half-life | weeks | Age at 50% activity loss |

Cognitive decline in killifish parallels mammalian aging, with T-maze accuracy and color association learning deteriorating over their short lifespan. This enables rapid screening of cognitive-enhancing interventions.
| Parameter | Unit | Description |
|---|---|---|
| T-maze accuracy by age | % | Cognitive decline trajectory |
| Color association learning | trials to criterion | Age-dependent learning speed |
| Memory retention | hours | Duration of learned response |

Age-related social disengagement in killifish mirrors patterns seen in aging mammals. Shoaling cohesion, aggression, and social preference tracked longitudinally reveal the social consequences of aging.
| Parameter | Unit | Description |
|---|---|---|
| Shoaling cohesion by age | mm IID | Social engagement decline |
| Aggression frequency by age | events/min | Age-dependent behavioral change |
| Social preference index by age | ratio | Conspecific interest over time |

Sleep architecture changes during killifish aging include increased total sleep, activity bout fragmentation, and reduced circadian amplitude — mirroring sleep disturbances in aging humans and rodents.
| Parameter | Unit | Description |
|---|---|---|
| Total sleep per day by age | hours | Sleep architecture changes |
| Activity bout duration | s | Fragmentation with aging |
| Circadian amplitude | relative | Rhythm robustness decline |
