Thank you for using Michigan State University Extension Ask Extension with your turtle pond question. Your question is a first for me. Most people love lots of turtles. Painted turtles are the state turtle. Yes, there will be some competition for food but not completely as painted turtles are omnivores. if they can catch the smaller fish they will eat them. But most are fast enough to avoid being eaten.
If you have a natural fishless pond it is ok to keep it that way. If you want to stock fish that is your option. It will chaange the foodweb dynamics. You may have less turtles thriving. You can harvest or move some turtles out but that may not be the best approach.
Understand that without active maintenance aeriators, fountains and feeding, stocked fish don't always do well in small ponds. Sun fish (bluegill) are the most tolerant of shallow warm water. And even they frequently sucumb to low oxygen levels in the winter. Fish also contribute heavily to the nutrient load in the pond increasing the instance of algae blooms.
My personal recommendation is to learn to love the turtles in your fishless pond. They do have fun little individual personalities. Attached is some more information to help you make your decisions regarding managing your pond.
