The Bergen County Mosquito Commission has acquired around 15,000 Gambusia affinis, also known as the mosquitofish, from the Hacketstown State Fish Hatchery. The season's wet spring and summer has made for ideal mosquito-breeding conditions. The conditions combined with the rising number of home foreclosures, which leads to unattended residential swimming pools and lots of standing water means there are mosquitos everywhere. The commission stocks the pools with the tiny fish so they can eat the larvae before they hatch into adult mosquitos. (Video by Andre Malok/The Star-Ledger)
