I put 17 Channel cats at about 8 inches in the late winter. I feed all my fish. These catfish are confirmed between 4 and 5 pounds in less then one year. If you dont mind feeding them I would say you can put more then 17 more like 50 just like the guys are saying. I have not noticed any muddying from them. I like them in there and am going to put 25 more and 5 albino cats. The good thing is you can get them out pretty easy if ypou dont want them anymore. My thought if they spawn, the bass love baby catfish so more forage for the bass and I am sure my neibors wouldnt mind a catfish dinner or two. I like them at least they bite. Hold your pole because channel cats will rip the pole right in the water.
