Sterile Grass Carp are used as an organic method of controlling problematic weeds instead of using expensive and harmful chemicals. They are a non-indigenous species from Asia and can easily become invasive. For this reason, only sterile carp are allowed to be sold in SC, GA, NC, among other states. They are individually hand blood-tested to confirm their sterility. Chemicals can be very expensive and require multiple applications. Grass Carp are far less expensive and will continue controlling weeds for approximately 8-10 years. Sometimes longer! They will start by eating their favorite plants almost exclusively. Stocking at the recommended rate is very important in order to achieve adequate results. Grass Carp will eat most aquatic plants and weeds. You may want to research the types of weeds you are finding in your pond to make sure they are a part of a Grass Carp's diet. They will not eat the fish eggs in your pond. You may find that they are coming to your fish feed. This is common, but they will continue feeding on weeds.
