Streams are dynamic aquatic systems that are difficult to predict. Fish move frequently, use habitats differently, and can generally remain undetected. Most people think that they know a stream pretty thoroughly, but time and again, electrofishing surveys turn up surprising results. Backpack electrofishing is the most effective and efficient method to sample a stream. The electrical current pulls fish out of the even the best hiding places and undercut banks. We use electrofishing surveys to estimate species abundance, determine growth, recruitment, and health, and remove unwanted species. Monitoring stream fish populations helps us to determine stocking rates, fish health, and to determine if adequate habitat is available prior to a stream restoration.
