Fishing bycatch refers to the unintentional capture of non-target species during commercial or recreational fishing. This can include various marine animals such as fish, sea turtles, dolphins, and seabirds that are caught alongside the intended catch. Bycatch can occur in different fishing methods, including trawling and longlining, where nets or lines capture more than just the desired species. The issue of bycatch is significant because it can lead to declines in populations of vulnerable species and disrupt marine ecosystems. Efforts to reduce bycatch include using specialized gear, implementing regulations, and promoting sustainable fishing practices to protect both target and non-target species.
