Grass carps typically live between 5 to 9 years on average. However, it is not uncommon for these fish to survive for 20 years or even longer under optimal conditions.
Understanding Grass Carp Lifespan
The lifespan of a grass carp (Ctenopharyngodon idella), also known as white amur, can vary significantly depending on environmental factors, habitat quality, and overall health.
- Average Lifespan: Most grass carps in various environments and managed systems will live for about 5 to 9 years. This range represents the common longevity for the species.
- Exceptional Longevity: While 5 to 9 years is typical, grass carps possess the biological capacity to live much longer. Records indicate individuals living for two decades or more, showcasing their potential for extended survival in favorable habitats.
The table below summarizes the expected lifespan of grass carps:
| Lifespan Category | Duration |
|---|---|
| Average | 5 to 9 years |
| Maximum | 20 years or more |
For more detailed information on grass carps, including their biology and management, you can refer to resources from reputable institutions like the University of Florida.
