Lake June to be stocked with grass carp for pondweed control

LAKE PLACID -On Dec. 17, the Florida Fish and Wildlife Conservation Commission will stock 2,500 triploid grass carp into Lake June as part of its management plan to control Illinois pondweed in the lake.

The plan, created with public input, also includes continued use of aquatic herbicides, if necessary, for maintenance control of Illinois pondweed in public-access areas.

Triplod grass carp are hatchery produced, weed-eating fish that have been genetically altered to prevent them from reproducing.

The triploid grass carp will be about 12 inches long when stocked. It will take 18 to 24 months for the fish to grow to a size (24-30 inches) where they are "efficient grazers," states a FWC news release.

"The goal is for the sterile fish to graze on the regrowth of Illinois pondweed, thus reducing the need for herbicide use."

The fish are being shipped by truck from Arkansas, where they are produced. Should inclement, icy conditions affecting a significant portion of the country prevent transport of the fish from Arkansas, stocking will occur sometime in January when conditions allow, the FWC added.
