| KHV in Texas
Don't know how real this is but it was sent to me by someone that i trust:
First Report of Koi herpesvirus in Texas. G. M. Southard and L.T. Fries
Koi herpesvirus (KHV) was detected in a common carp, _Cyprinus
carpio_, collected from a fish kill during May 2006 at Twin Buttes
Reservoir near San Angelo, Texas. Also known as carp nephritis and
gill necrosis virus (CNGV), KHV is highly contagious, infects both
common carp and ornamental koi carp, and can result in high mortality rates.
Biologists from the Texas Parks and Wildlife Department (TPWD)
investigated the kill and estimated 500 dead common carp along a 1-km
segment of shoreline, which converts to thousands of dead fish in the
reservoir. Surface water temperature was 22C and dissolved oxygen
measured 9.2 mg/L. One moribund fish was collected and shipped to
the Southeastern Cooperative Fish Disease Project at Auburn
University where KHV DNA was detected using the polymerase chain
reaction (PCR). A concomitant _Flavobacterium columnare_ infection
was also observed, and it is unclear what role the virus played in
the fish kill. This is the 1st known report of KHV in the state, and
the virus has the potential to affect wild populations as well as
TPWD hatcheries, which use koi carp as a forage for some species of
captive brood stock.
