Grand Park Lake and LightsWESTFIELD, IN – As a preventative measure for the summer season, Grand Park recently stocked its lakes with Gambusia affinis fish (also known as mosquitofish).

“Grand Park is focused on preventative measures to ensure the safety of our visitors,” says Ken Alexander, Director of Grand Park. “These fish will help control our mosquito population in a natural way.”

The Gambusia affinis fish feast on mosquitos and eat up to 500 larvae per day (3x their body weight). Due to the amount of ponds at Grand Park, 6,600 fish were stocked for the 22 acres of water. They also spawn regularly throughout the summer with broods of up to 100 at about six week intervals.

While these fish should be helpful in controlling the mosquito population, visitors are still encouraged to apply insect repellent containing DEET.
