I've heard a lot of people claiming to have caught a blue cat from the Ohio River. I believe it. BUT when I hear someone claiming to have caught one North of the OH/ KY border, I become a bit skeptical. Here's why and it's simple. The OH/KY border is the blue cats northernmost range in this part of the country. They thrive in deep water with current. The part of the Ohio River I fish runs by Marietta, Oh. It's not particularly deep, even right above a dam. There's a huge misconception amongst some catfishermen that male channel cats are, in fact, blue cats. I've nearly gotten into heated arguments over this issue. It usually ends when I say,"Take that fish down to the Senecaville hatchery & ask those boys down there what kind of fish it is." Physically,a couple differences are found in the anal fin. A channel cat has 24 to 29 rays in it's anal fin. The fin itself is rounded. The anal fin of a blue cat has 30 or more rays and a straighter edge. Habitat aside, this is the foolproof way to tell the difference. Color really has little bearing on it although there are small differences in coloration between the two. That said. Has anyone caught a blue cat in the part of the Oh River I've been fishing? I mean a real, bonified blue cat? If so was it above a dam? Deep water? Whatever info you give up would be appreciated:big_smile: I'm not looking for any secret spots. I don't think they're even in those waters. Just curious if there may be a small pop. in one of the northern pools.
