Selective fishing is a method that targets specific species of fish while minimizing the catch of non-target species. This approach helps to maintain the balance of marine ecosystems and supports sustainable fishing practices. By focusing on certain fish, fishermen can reduce bycatch, which is the unintentional capture of unwanted species. This technique often involves using specialized gear or fishing techniques that are designed to catch only the desired fish. For example, traps or nets can be modified to allow smaller or non-target species to escape. Selective fishing aims to protect vulnerable populations and ensure the long-term health of fisheries.
