Redwood National and State Parks - Redwood Ranger Minute: Counting Salmon

The video explores the Redwood Creek estuary, highlighting the process of counting fish to estimate population sizes. Biologists use nets to capture fish, which are then tattooed for identification. This method helps estimate fish numbers using ratios, aiding in understanding the estuary's health as a fish habitat. The process involves capturing, sedating, tattooing, and releasing fish, with minimal harm to them. The video emphasizes the importance of these estimates for ecological health.
