I was just wondering if anybody has ever tried raising fish in old above ground swimming pools.

I would think there would be no problem with soft fish like goldfish or trout but I'd be afraid that the spines of tilapia and especially catfish would cause leaks by poking holes in the lining of any soft pool and maybe even a 45 mil fish rated pond liner! I don't know the thickness of an average swimming pool liner but I know you can buy new liners for an old pool at 25 mils thick. Does anyone know of anyone with first hand experience with talapia or catfish poking holes in above ground swimming pools?
