I've also read where cedar shakes removed from roofs can make it into cattle feed also. I guess anything for a filler. Also read an article that catfish is the only fish when raised in captivity is actually better than the wild variety. Now mind you, it was on the computer so I take anything and everything I read on the internet as NOT necessarily the gospel.
Farmed catfish eat commercially produced pellets. These delicacies are fed a gourmet diet of puffed, high-protein food pellets, made of a mixture of soybeans, corn, wheat, vitamins and minerals. Farm-raised catfish have learned to feed on pellets that float on top of the ponds, unlike its wild bottom-feeding cousin. This feed not only helps in producing a healthier fish, but also a cleaner, milder tasting one.
And my choice is?-----You guessed it!
