RCEI’s Research and Grants Facilitator, Joyce Ong, co-authored a new study that develops a new method for tracking fish movements and life history. By analyzing chemical signatures in small calcium carbonate structures within fish ears, called otoliths, scientists can surpass traditional, heavily oversimplified approaches of investigating how fish change and adapt throughout their life span. This is crucial for predicting how populations will respond to environmental changes, allowing for better “fisheries management and conservation” in uncertain times.
