Virus Linked To Large Lake of the Pines Fish Die-Off

A nationwide fish virus has been detected in California for the first time, causing a significant die-off at Lake of the Pines. Officials say there is no threat to human health, but caution against moving fish.

A recent large fish die-off at Lake of the Pines has been linked to the presence of a nationwide virus that’s been detected in California for the first time.  Department of Fish and Wildlife Public Information Officer Peter Tira says the Largemouth Bass Virus caused the deaths of 220 fish, which also included some bluegill as well. There are no health risks to anglers who consume largemouth bass or recreational users who swim in or drink the infected water and the virus has also pretty much run its course. Tira says the source has not been identified. But he notes the die-off happened over Labor Day weekend, when temperatures were still very warm and there were a lot of recreational activities going on at the time on the 232-acre private lake…

Tira says it’s not clear yet whether this will be an isolated event. But recreationists should assume the virus is still present in the water and not move any fish from the lake unless it’s for immediate consumption…

Tira says the Largemouth Bass Virus was first documented in Florida in the 1990’s. He says outbreaks can last for days or weeks before they resolve on their own. There are no available treatments or vaccines.  Typically, an outbreak will result in the mortality of a high percentage of the older and larger fish, which are popular for anglers.
