Sneaky fishies!
It certainly would be easier to perform "perfect pond management" if we had perfect information on the fish populations of our ponds.
Unfortunately, the fish do NOT submit a nice census for our records.
Keep observing during your feedings and recording the measurements when you catch fish.
Even though you never will achieve a "perfect" pond, just moving the pond in the right direction is a job well done.
Good luck on your pond improvement projects!
