Cecil, I was wandering if you are aerating your cages, and with what. My pond (1 acre) is aerated 24/7 although my cages are located about 25yds. from the bubbles, I wonder if aerating directly in the cage would be better. The netting I used has 1/2 in. holes and I'm woried about the circulation of fresh water through the cage. With water temps. warming I plan on raising the cages to the surface this weekend.
