Pond Boss Forums Thread Like Summary - channel cat spawning habitat

I just stocked my pond with channel catfish. Now I need to start learning about what it takes to support their spawn. Can anyone tell me the best thing to use for their spawn? And how many. For example, I stocked 100 and assuming they are 50/50 male and female, do I need to provide 50 spawning facilities such as pipes, etc.? Or will more than one pair use the same spawning space?

This is What I did in my pond that worked well. I bought eight food grade barrels that tapered at the end and filled them with large river rock(100lbs) and some very large stones. I drilled multiple holes at the top so that the air would escape. I was able to float the heavy barrels out into 4 ft of water and submerge them that way( open end facing the pond). I tried filling them with a 100 lb of pea gravel in an earlier experiment but something kept on knocking the gravel out which made them float. I measured 4 ft on my body to know how far to walk out to submerg the barrels.I also used a 2 wheel moving dolly and a piece of plywood to get the heavy barrel into the water. Oh wooden boxes would probably be easier but it was more costly. I bought the used food grade barrels off if craigs list $5 each. I hope this helps someone, enjoy!
