I just received this an email from the Eastern Lake Erie Charter Boat Assoc. Another fish disease has struck NY, this time in a hatchery. Here is part of the message...

DEC AND PARKS CONFIRM IPN FISH VIRUS AT LONG ISLAND HATCHERY
Disease Poses No Known Threat To Human Health

The New York State Department of Environmental Conservation (DEC) and the New York State Office of Parks, Recreation and Historic Preservation (OPRHP) reported that a fish virus, Infectious Pancreatic Necrosis (IPN), was found recently in samples of trout from the hatchery on the Connetquot River State Park Preserve on Long Island. There is no known health threat to humans who handle or consume fish that contain the IPN virus, but IPN is considered a serious fish disease capable of causing extensive mortality in young trout.

IPN is most often associated with affecting trout and its symptoms range from turning fish fry a blackish color, to affecting fingerlings with hemorrhages or exophthalmia (also known as “popeye”). When IPN infects hatchery fish, it can affect that population for some time, then go dormant for many years before reemerging. The disease can cause extensive mortalities in affected fish populations. The hatchery fish do not always display symptoms of IPN and have the potential of infecting wild trout or other fish species if introduced into a body of water, potentially resulting in a mortality event.

The virus that causes IPN was found in samples of brook, brown and rainbow trout that were collected from the hatchery in November 2006 and sent to DEC’s Rome Fish Disease Control Unit laboratory for analysis. This was conducted as part of a fish health inspection program conducted by DEC at state-owned and private hatcheries that raise fish to be released into the state’s waters.

The virus may be transmitted from infected fish to uninfected fish, and from parent fish to their offspring. There is no demonstrated cure for IPN. It is not known when this virus first became present in trout at the Connetquot Hatchery because previous annual fish health inspections were focused solely on the whirling disease parasite.

DEC initiated more comprehensive fish health inspections in response to Federal action taken in Fall 2006 involving a different fish virus, Viral Hemorrhagic Septicemia (VHS). DEC regulations now require inspection for a number of fish pathogens and parasites as part of an overall effort to protect New York’s aquatic resources and hatcheries from harmful diseases or infections. For additional information on the VHS emergency regulations adopted by DEC, please go to http://www.dec.state.ny.us/website/dfwmr/fish/vhsv.html#DECsteps on DEC’s website.

DEC and OPRHP are in discussion on what to do with the infected trout. Staff from DEC and OPRHP will work collaboratively to develop a plan that will seek to break the chain of infection while maintaining the high quality fishing experiences many anglers have come to expect at the Connetquot River State Park Preserve. Anglers seeking specific information about fishing opportunities within the Preserve should contact Preserve staff at 631-581-1005.

Governor Eliot Spitzer’s 2007 - 08 Executive Budget proposes a total funding commitment of more than $1.1 billion for DEC, recommending the addition of 109 new positions, including a wildlife pathologist and a fish pathologist to assist in the state’s disease response efforts.

This stuff seems to just keep coming and coming. Charliedog and I were talking on the way back from Erie and he said that every time you turn around these days there seems to be some new fish or wildlife disease. Will it ever end???

Thanks for the post Gilligan. Looks like i'm going to have to call my NY State Dept. Of Health Biologist buddy and get him on the show.

I'm glad we have been so lucky in Pa as to not get to many diseases in our wildlife.

We've been lucky here in PA yes but wait they'll get here.
