I always see pics of channels from the states and they're always little guys. Good 'eaters you'd say. The average is between 15-25" that I see. On the odd occasion I'll see a pic of a larger fish but primarily they're all smaller. I also noticed that alot of people are fishing small little creeks for em. I guess what I'm trying to get at is up here our average is from 25-35 inches. I dunno if it's less competition or what!? I commonly see cats chasing goldeye and eating them from the surface. Maybe it's because of an abundance of prey species? Now I know people are going to get all defensive and say that the US cats are biggers, blah blah blah. I'm just stating an observation is all. I belong to a local fishing forum from up here and the sheer numbers of big cats is truly remarkable! It's not uncommon to catch 5-15 cats a night between 30-40 inches! Up here we don't eat the cats though and there's a slot size where it's the law to release them. So maybe they're big because of that!? Just wondering is all.
