Today was especially depressing.  I found out that our power outage did affect our fish.  On Saturday we had an outage that only lasted a small period of time.  I had about 40 rainbow trout averaging 3" in a fish tank in my classroom that died, but it didn't look like any of my trout in the pool aquaponics system were affected. Apparently, I just needed to wait a few days for the fish to start floating.
