Emergency Burn Ban In Effect 10/26/24 - An emergency burn ban is now in effect for all Connecticut State Parks, Forests, and Wildlife Management areas, prohibiting the use of all outdoor grills, firepits, and campfires, and the kindling and use of flame outdoors. DEEP and local agencies are working to contain several active fires across the state. Please avoid all affected State Parks and Forests, as well as the blue-blazed Mattabesett Trail. The Enduro Trail in Voluntown and portions of North Stonington within the Pachaug State Forest are closed at this time. Please note that today's forest fire danger report remains at an 'extreme' level. More information about the current fire danger, burn ban and recommended safety measures can be found here

Emerging Diseases

Plants, invertebrates and fish aren’t the only invaders. Just as insidious are a number of new diseases and parasites that affect fish (but are harmless to humans).

Largemouth Bass Virus (LMBV)
Largemouth Bass VirusLargemouth Bass Virus is a relatively new disease that has been found in Connecticut.

This virus was first found in 1991 at Lake Weir (Florida). Originally thought to be limited to southern waters, this disease has spread northwards into the Midwest and Northeast.

Although LMBV can infect a number of fish species, it is only known to cause mortality of largemouth bass, and has been responsible for a number of notable fish kills throughout its southern distribution.

LMBV can be transmitted by consumption of infected prey, through the water, and by fish-to-fish contact. The virus is thought to be most active during the warmer summer months. Because the virus may survive in water for up to a week, it can be transferred between water bodies in improperly cleaned live wells.

Stress appears to promote the onset of symptoms that can lead to death. Common stressors include warm water temperatures, low dissolved oxygen concentrations, overcrowding in live wells, and improper handling by anglers.

DEEP Fisheries biologists first began collecting largemouth bass to test for LMBV in 2005 and a number of Connecticut lakes have been sampled. Bass from Amos Lake (Preston) and Gardner Lake (Salem) have tested positive for LMBV.

Properly cleaning and disinfecting boats, live wells and gear will help prevent the spread of this virus. Anglers should never transfer fish between water bodies!

Viral Hemorrhagic Septicemia (VHS)

Previously associated with salmonids in Europe and some marine finfish, a new strain has been found in the Great Lakes. This new strain affects a wide range of freshwater fish species, and has caused kills, some significant, of a number of different fish species in the Great Lakes. To prevent the spread of VHS, the USDA in late 2006 placed special restrictions on the interstate transport of live fish from the eight states that border the Great Lakes.

Spring Viremia of Carp (SVC)

This highly contagious viral disease mainly affects minnow species, most notably common carp (including domesticated koi). Once infected fish show symptoms, mortality ranges from 30 to 90%. First North American outbreak was observed in a koi farm in North Carolina in 2002. The virus has since emerged in wild carp populations in Wisconsin and Illinois, and in koi ponds in Washington State. This virus can survive in water or mud for at least several weeks. USDA is developing regulations that place special restrictions on the importation of SVC-susceptible species into the United States.
