Greetings all, I have a 1 acre pond, 15 years old and 6' deep. The past two years the springs that fill the pond have slowed down to were the pond would drop about 2'during the summer. The past 3 weeks the BG have starting dieing, as of today 120 are lost. They are all 6-8". My LMB and Crappie are doing good. The man who checked the fish say they are dieing from stress and old age. The liver in the fish are almost white and there are stomach ulcers. I was told the ulcers could be from fire ants, I had a little runoff washed in back in Oct. that may have washed some fireants in. The fish will lay on the bottom and when you try to net them they swim about 5' and lay on their side again. I feed 36% Nutrena fingerling. I got busy last year and didn't keep the PH right and got alot of alge bloom.Thanks for any help
