I want to know the pro's and con's on raising catfish ver's talaipa the temp food feed and all of that could you let me know if you have any suggestion.
My partner says heat is of a less factor with catfish then talaipa and temp change please help me if you know any thing.
Al, you could stock with mostly Tilapia and have a few cats for bottom feeding and tank cleaning. And since you have a GP style system with shallow grow beds, I would keep the stocking density extremely conservative at 1 fish per 10 gallons to start. There's not much biofiltration in those grow beds.
Channel catfish will thrive in a far wider range of temperatures and in central Florida the channel catfish have grown much bigger much faster than my tilapia did. I've had catfish survive water down into the 30's. And plants can definitely grow in water cooler than 70 F. Winter with water temps between 50-65 F seems to be when many of my plants are doing great. Catfish still eat at those temperatures though not as much as when the water is over 70.
