What is the primary purpose of electrofishing?

The primary purpose of electrofishing is to capture fish safely for research purposes. This method allows researchers to selectively stun fish in a controlled environment, making it easier to collect samples for various studies without causing significant harm to the fish. Electro-fishing enables scientists to gather important data on fish populations, species diversity, and ecosystem health, which are crucial for effective management and conservation efforts.

Other options, while related to the broader context of fisheries management, do not encapsulate the main goal of electrofishing. Improving fish habitat, enhancing fish growth rates, and monitoring water quality are all important aspects of fisheries management and conservation but are not directly related to the primary function of electrofishing as a tool for fish capture and data collection.
