Coastal habitats serve essential roles in the life cycles of migratory fishes, impacting both local and regional population stability. Conservation efforts for coastal fish often rely on spatial approaches within designated boundaries to mitigate threats enhance production. However, open environments, behaviours can extend beyond these protected areas, exposing individuals potential or bottlenecks elsewhere their range. To improve conservation outcomes, a comprehensive understanding movements across entire range is essential. Aquatic telemetry valuable tool studying behaviours, but must be adapted address questions at multiple temporal scales. In this study we demonstrate how combination techniques capture behaviours. We begin by introducing implications using Wadden Sea as an example where additional research management are needed declines. then present case which uses Dutch illustrate multi-scale approach fundamental knowledge strategies fish.
