Bycatch refers to the unintended capture of non-target species during fishing activities. This can include various marine animals such as fish, sea turtles, dolphins, and birds that are caught alongside the desired catch. Bycatch can occur in different fishing methods, including trawling and longlining, and often leads to significant ecological impacts. The issue of bycatch is a concern for sustainable fishing practices, as it can result in the decline of certain species and disrupt marine ecosystems. Efforts to reduce bycatch include the development of specialized fishing gear and regulations aimed at protecting vulnerable species, ensuring a healthier ocean environment.
