Hi all, Yesterday I started noticing my large perch 12" in my small 1/5 acre pond are all up at the edges of the pond and not moving very quickly, you almost can pick them up and last night 3 died. I have had this pond for 20 yrs. and not sure what the heck happened this week. What I can tell you is I started running my aeration bubbler about a month ago and only run it 2 hrs a day right now. I also had a lot of algae in my rock ledge so we I mixed a gallon of Cutrine plus and sprayed my pond with it and then ran my bubbler for about 24hrs to mix the pond up to get a good kill on the algae. I also added 4 large mouth bass to my pond this week which were about 10in in length. Do I have an oxygen problem or stress these fish out somehow. The perch just came off the spawn a couple weeks ago. Any help would be appreciated as these fish are dying fast. I actually know Bill Cody personally and hoping he will chime in. Thanks Todd
