Las Vegas, NV (KTNV) -- Clark County Vector Control and the Water Reclamation District have teamed up on a new program to produce mosquito-eating fish as part of the county's efforts to fight West Nile Virus.
There is a room at the Water Reclamation District's building on East Flamingo with several large holding tanks where the fish, called Gambusia Affinis are raised.
The fish are later transported and deposited into ponds and other bodies of water around the valley.
One place you would likely see these fish are the ponds at the Desert Rose Golf Course near Sahara and Nellis. Clark County vector control supervisor, Christopher Bramley, said it is the perfect example of why these fish are helpful in controlling the mosquito population and the spread of the West Nile Virus.
Bramley pointed to the Las Vegas Wash that runs through the golf course and says that the fish can swim through the water and get to places where mosquito and their larvae may be in the water in areas that chemicals can't reach.
The county has been treating bodies of water suspected of being breeding grounds for mosquitoes in this way for several years. But it was only a couple of months ago when vector control workers started using the wastewater treatment plant to breed the fish.
Bramley said that gives them access to as many fish as they want whenever they want. In past years, workers had to get the fish from traps that they had set in outside bodies of water.
While summer tends to be the height of the West Nile Virus season, the county is still urging residents to be vigilant and notify their local code enforcement offices if they encounter green pools which may foster mosquitoes and increase the risk of West Nile Virus.
