Hi folks, it's been a while since I was here last. I tried searching for solutions but did not find any yet. Hoping some of the experts can chime in.
I'm having a problem with my bluegill in my 1/2 acre pond. A couple weeks ago I noticed lots of medium sized BG hovering above a bed of Brittle Naiad. They seemed to be waiting for bugs. Over the past week I have retrieved about 5 dead ones. Today I noticed 2 more dead and about 20 of them hovering above the Naiad like before. This time I noticed some of them had very dark (almost black) bodies. One had pronounced white lips. Fins were almost white. Most were active, some a little sluggish. They were all swimming upright and not sucking air.
To this point they are all medium sized BG. No large BG, bass or catfish problems so far.
Last week I did broadcast about 8# of Hydrothol and sprayed about 8oz. of Reward on the surface of the Naiad. The pond is aerated and the planktonic is a healthy green with at least 3 feet of visibility. No changes there in last 6 weeks.
