Avoid hooks larger than size 10 (hook sizes run backwards—size 12 is smaller than size 10). Fish won’t readily take large hooks unless they are feeding voraciously.
Most of the time, a subtle presentation is needed to catch wary fish. Tiny hooks also allow small fish to “inhale” the bait, rather than nibble at the hook. Don’t get me wrong, to small of a hook can be a problem too. That is why you should study your prey and learn from seasoned anglers. Hitting up the local pro shop to ask a few questions isn’t against the rules so don’t be shy and be sure to download as much info as you can before hitting the waters to catch some fish. A little knowledge and a little research will ensure you have just the right hooks.
