I have excessive weed growth weed growth in my pond and don’t know how to control it. Can I obtain assistance from IDNR?
Excessive vegetation in a pond can be managed through chemical, biological, or physical means or some combination of these measures. The first step toward prudent vegetation management includes identification of aquatic plants. Once plants are identified, an appropriate approach for control can be formulated. Contact you local IDNR district fisheries biologist for literature and advice. My pond has an algae problem, can I stock grass carp to control this? Grass carp aren’t generally stocked for algae control. They will tend to only eat fillamentous algae if there is nothing else better available to them. In so doing, the body of water would convert itself to planktonic algae which is worse. Our own fish hatchery, Jake Wolf, got rid of the grass carp they had for just that reason. They were making water quality problems which hurt the young fish and clogged the filters.
