I haven't read any literature on yellow perch, but assuming you are planning to grow them out to 50 lbs from something small, you can start without adding any aeration equipment. The flood/drain grow bed adds a lot of oxygen, which is why I asked what type. This is good. I would try it without and special aeration equipment like bubblers and just see how they react from week to week to the conditions they are in. The most critical times will be towards the end of their grow-out period and the few hours after you feed them.

Also, the more surface area you get on the fish tank where the water touches the air, the better, but I don't know if you have the option to change that in your design.
