Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Weeds in my aquaculture pond

The weeds are a catch 22. They provide cover for the YOY to hide in, both forage and predator YOY. They utilize nutrients that phytoplankton would use. The weeds using the nutrients contribute to the clear water, which allows sunlight to reach deeper into the water which allows more weeds to grow....

If the ponds don't have a good amount of water inflow and outflow in the spring, you could treat the weeds chemcially early in the year to get a phytoplankton bloom going, which woud reduce the amount of sunlight getting to the pond bottom, which would inhibit weed growth.

Are the other water parameters good to foster a phytoplankton growth? (hardness, alkalinity, N and P levels?)

Make sure the weeds in the pond are the type that don't propagate from cuttings, or you will compound the problem mechanically cutting the weeds or mechanically removing them.
