To be honest, I am not sure if the pond has or has ever had fish, but I know I have seen turtles (in other ponds) and frogs.For sure they waited almost a year for the trout to get to be nice sized, I was shocked at the efficiency of the clean out not one left.

The one thing I have to check is the depth of the pond as that will determine if fish are even possible and if they will survive (longer)
Also, there is nothing for them to hide under or any basking spots, so I may address this as well.
But this all means nothing if the pond continues to be left stagnant, so aeration is job # 1
Also have to look at getting the barn roof repairs as it leaks, mostly from the home-made skylights that are well past their prime.
Thank goodness they removed that old trailer...
