Does using a red hook make a difference? I've mentioned before that I sometimes prefer them (and I do) and there's been a lot of talk that red hooks are what you need for good crappie fishing. Still, is it true? Red mono is apparently not visible to fish, but red hooks are supposed to help? How does it make sense? Well, red mono can be seen by fish, until it reaches a depth where the light isn't strong enough to reflect the red color, which is the situations it's usually used in. And even then, it doesn't disappear, but looks black or gray. Red hooks can be seen by fish, too. It's just that it's perceived as part of the "bait", so it's only another color in the scheme of colors your bait happens to be. The "red" color is reflected back from the hook, because the hook is solid/reflective. The "red" color of mono isn't reflected back as strong, because the mono is transparent/translucent. The red hook will look grey/black, too, once it achieves the depth where light isn't penetrating enough to reflect the color. I have some red aberdeen hooks and use them, especially on those really finicky days. I also believe that water clarity in combination with light penetration at deeper depths has a lot to do with any color jig, skirt, hook or whatever presentation you're making to the fish. I can see that a red hook is perfect on day and a gold or black hook another depending on the circumstance. Personally, I have no personal preference other than what works that day, so don't get too sure in any color and just base it off the situation.
