Which fishing method results in very low bycatch and is preferred for sustainability?

Pole and Line

When evaluating the ecological impact of fishing gear on marine ecosystems, the pole and line method stands out as the most sustainable approach specifically mentioned for catching yellowfin tuna. This technique involves a single line, a hook, and often a lure or bait fish, resulting in an extremely high degree of selectivity. Consequently, it generates very low rates of bycatch, meaning the accidental capture of non-target species like sharks, sea turtles, or marine mammals is minimized. While trolling is also considered a selective method for targeting individual, larger fish, pole and line is emphasized as the gold standard for achieving minimal ecological interference, supporting its preference among consumers prioritizing responsible seafood sourcing.
