Lifespan, ageing, and relevant traits
- Maximum longevity
- 8 years (wild)
- ref. 1
- Sample size
- Data quality
Data from wild populations suggests these fish do not reach sexual maturity until they are 2 years old, though laboratory strains can mature and breed earlier. One study reported that age at maturity in wild Alaskan sticklebacks appears to be delayed by both their anadromous life-style and increasing latitude. Additionally, fish from marine populations were found to be significantly older than those from freshwater populations .
