Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Stocking new fish dying

Unless you can make a detailed inspection of the whole pond bottom, don't assume that the only fish that died are the ones that you can see. Some will die and sink, never to be seen.

Think of the volume of water in the pond as a savings account for dissolved oxygen. The more water, the more DO available to the fish. Smaller shallower ponds usually have O2 depletions before larger, deeper ponds.

But, that's also why you will see "it all depends" tossed around here. No two ponds are alike, even though you think they are identical in construction and O2 demands.
