European flounder can complete whole life cycle in freshwater
European flounder have been found to complete their life cycle in a Finnish lake, with no evidence they ever entered saltwater. This is a significant finding for the species and its ability to adapt to freshwater environments. The study indicates that this behavior is common among flounders in Lake Pulmanki.
Why it's good news: It suggests that European flounder may be more resilient to environmental changes than previously thought, allowing them to thrive in a variety of aquatic ecosystems.
