Whether you’re interested in creating a prized trophy fishery or just want to improve the health and longevity of your fishing pond, electrofishing is an essential tool for fisheries managers. This method is the primary sampling technique used to gather necessary information about the current state of a waterbody and determine what can be done to meet or exceed the goals of the specific fishery.
What exactly is electrofishing?
Electrofishing helps biologists track reproductive success and survival rates of fish species. The assessment is performed by sending an electric current into the water in order to safely stun any nearby fish. Stunned fish can then be easily scooped up in a net and placed in a temporary holding tank where they can revive and be observed for data collection. Most often, fish are measured, weighed and marked with PIT or Floy tags, which are used to determine the health and growth of the fish year over year. Then, they are released back into the water completely unharmed.
