Quick Answer
Yes, there are risks of bycatch with handlines, which can include non-target species such as turtles, fish, and other marine life, potentially leading to injury or death for these animals.
Bycatch Risks with Handlines
Bycatch is a significant concern in handline fishing, as it can result in the accidental capture of non-target species. This can include turtles, which are protected by law in many countries. According to the Food and Agriculture Organization (FAO), turtles are among the most common bycatch species in handline and longline fishing. In fact, it’s estimated that up to 90% of sea turtles caught in fishing gear are incidental bycatch.
Reducing Bycatch with Handline Techniques
To minimize bycatch when using handlines, it’s essential to use proper techniques and gear. One technique is to use a ‘circle hook,’ which is designed to reduce bycatch of non-target species. Circle hooks have a curved shape that makes it easier for fish to escape once they’re hooked. A study conducted by the National Oceanic and Atmospheric Administration (NOAA) found that the use of circle hooks reduced bycatch of sea turtles by 80% compared to traditional J-shaped hooks. Another technique is to use a ‘pilot hook,’ which is a short, thin hook that’s designed to snag a fish’s mouth without hooking the throat or gill rakers.
Best Practices for Handline Fishing
To reduce bycatch and minimize the impact of handline fishing on the marine environment, it’s essential to follow best practices. This includes using circle hooks or pilot hooks, as well as carefully selecting fishing grounds and avoiding areas known to be sensitive ecosystems. Additionally, anglers should handle caught fish gently and humanely, and release them unharmed if they’re not intended for consumption. By following these best practices, handline anglers can help reduce bycatch and promote sustainable fishing practices.
