Pond Boss Forums STOCKING A NEW POND Types of fish to choose rainbow trout activity, please advise

That trout and probably others are stressed due to too warm of water. Water may be cold deep but it could not have very much dissolved oxygen - DO. It is not normal for a trout to be that shallow in a warm watrr pond in the heat of summer. The fish is probably very stressed and looking for DO and the heat is killing him. Just because the pond is deep and has cold water deep does not mean there is adequate or high enough DO in the correct water temperature for trout.

This is a common misconception of new pond owners who think because the pond is deep with cold water in the bottom trout will survive. Temperature can be cold enough but very frequently the DO becomes too low in the heat of summer for the trout to survive. Trout typically need 5ppm DO compared to other fish who can survive okay at 3ppm or lower depending of some other factors.
