Great news for cold tub perch......not so hot for the hot tubbies.
After over two months at the farm I still haven't had a floater. Unfortunately that is not the case for the fish at home. Each of the last three days I've found a perch that, to the best of my abilities of perception, was not "asleep", but maybe just a little dead.
I decided that I must have water quality issues so I relocated the home yellow perch back to the farm. I think my wife was killing them as I slept.....maybe she's been fishing for them with conventional hooks instead of the circle hooks I gave her for Christmas last year....
