Bullhead catfish question pertaining to hooks.
Catching bullheads is super easy. In fact, it’s easier to gut hook almost every fish you catch, because once they eat it, they swallow it. There’s nearly a 100 percent fatality rate when it comes to bullheads. Even if you cut the hook off and release the fish, they typically don’t make it.
Now, in my pond, bullhead catfish are the main food source for the bass. While I want to catch them, I don’t want to eliminate that food source.
So the question is, what is the ideal hook size to catch them in the lip and prevent them from swallowing it?
Now we’re talking mechanics. Obviously, circle hooks are the best option. Here’s some background on what I’ve experienced: I’ve had fish swallow every hook I’ve used, including a 3/0 octopus hook, completely down into the stomach before I could even react. They bite, you try to set the hook, and it’s already gone.
So how big of a circle hook should I be using? 3/0, 4/0, 5/0, 6/0? Do I go as big as a 7/0 to try and force a lip hookup?
That’s really the core question. How do you prevent them from swallowing the hook, and how big do you go?
One approach I’ve considered is float fishing, letting the wind drift the float toward structure while keeping the bait just off the bottom. I’d run something like a 4/0 thin wire circle hook so the float helps hook the fish. A thin wire hook penetrates easier, requires less force, and acts almost like a needle. It’s big enough to get a bite, but still sharp and efficient enough to stay pinned in the lip.
But again, how big would you go to maximize lip hookups while minimizing gut hooking?
The bullheads in my pond average around two pounds. Their mouths are roughly three to four inches wide, and they can easily open wide enough to swallow something the size of a golf ball. That’s something to consider.
I even have a set of 6/0 circle hooks from Mustad, and they could still swallow those without much issue, both horizontally and vertically.
So the question remains, how big of a hook gives you the best chance at hooking the lip while reducing the likelihood of gut hooking?
That’s the question of the day, with enough detail to hopefully get some solid, educational answers.
