My experience is fairly limited in that I just stocked them 2 years ago. I don't have spawning structures at this time for a couple reasons.... 1) I don't know if I want them to spawn in sufficient numbers. From what I've read they can really do a number on smaller prey fish like bluegill. If I ever want to reduce my number of blue cats, I'd rather not fight them being prolific spawners. 2) Unlike Channel Cats, Blues don't reproduce until they are older. I think they have to be around 5 lbs to spawn from what I've read. So next year is the first year spawning will be a concern for me as mine are just reaching that size.
Otherwise, I love the blue cats in my pond. Beautiful fish. And knowing they may eventually reach 20-50 lbs is enticing.
