I went to my pond early this morning and saw a 2lb LMB in 6 inches of water facing the bank not 2 inches away. It looked like he was parking in the front row about to walk on land. I walked to about 3 feet from him until he finally jolted to deeper water. Does this mean that he is searching for oxygen. I fear that I may have had a pretty significant fish kill because there are not many signs of fish other than a few large ones and many babies. I have not seen 1 fish dead yet and I was wondering do dead fish always float or do they sometimes sink to the bottom pretty fast. I am getting up at daybreak to see if there are any fish gasping for air right at daylight since that is the time oxygen is at its lowest. I have a lady coming from the Tx Cooperative Extension to check my oxygen levels tomorrow. If my O2 levels are low, will a 5 hp Hydromatic sump pump pushing 60 GPM put at about 3 ft of water shooting water horizontally across th top of the water put enough O2 in the water to make a difference. The only problem is it pull 14 amps so I wouldn't want to run it continuously due to cost. I'm thinking at night for sure and maybe during the day intermittent to cut down on the ongoing algae bloom in the middle of the day. Suggestions?
