Scientists Use Electrofishing to Sample Stream Population

Understanding the dynamics of a river’s or stream’s fish population is an important aspect of many restoration projects. Environmental scientists frequently use a method called electrofishing to monitor changes related to restoration efforts. The process makes use of electricity to momentarily stun fish so they can be easily caught and studied. After collecting the necessary data, the fish are released back into the water, unharmed. By surveying the number and type of species present prior to work starting and then again after, scientists can then use this data to evaluate a project’s ecological benefit.
