Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Checking your fish population?

Here's another idea, Tony. Start feeding the fish once water temps rise to the upper 50's, probably the second or third week of March where you live. Catfish and bluegill will come to the feed. It may take a week or two to get much response, but if fish numbers are high, competition will be high, too.
A survey tells the tale, but as I recall, your pond is new.
Try feeding floating fish food in March. Use Purina Game Fish Chow for now.
