Thought I would start a thread for 2013 of a general nature regarding ponds as they progress into summer. For instance, my pond is thawing out and I am experiencing a greater (by a bunch) degree of fish death (just --- yeah, JUST goldfish --- but they are my fishies and mourn them). I found four fairly large (for me) gold fish in the skimmer dead with three more rimming the bowl (so to speak) at the bottom. Can unseasonably warm weather while there is still at least a thin ice cap on the pond (not including holes for air and the skimmer is totally ice free) contribute to fish death? Not sure how long this has been going on as the snow just melted enough to let me uncover the skimmer.
