Bacterial disease blamed for dead fish on Wilson, Wheeler
A bacterial disease is blamed for the deaths of hundreds of catfish on Wheeler and Wilson lakes in recent weeks, conservation officials said today.
Keith Floyd, a supervising fisheries biologist for the Alabama Department of Conservation and Natural Resources, said he began receiving reports of dead catfish on Wheeler Lake about a month ago. He added he received a report today about dead catfish being found on Wilson Lake over the weekend.
Floyd said the fish are dying from columnaris disease, which is caused by a bacteria that becomes more active when water temperatures are high. Water temperatures in local lakes were in the lower 90s earlier this month and are now in the upper 80s. With water temperatures now cooling, Floyd said the problem should begin winding down.

Old disease suspected of killing deer again
An old disease is suspected of moving north again to kill New Jersey deer.
The Division of Fish and Wildlife last week was seeking fresh tissue samples from dead deer to be tested for EHD (epizootic hemorrhagic disease) after hunters preparing for next month’s bowhunting deer season began finding dead deer in the woods near water.
EHD has been in the U.S. since 1890, and Serotype 1 of it was first seen in our state in 1955. Deer that survived Type 1 wouldn’t be immune to Serotype 2. Both types are deadly to 25 percent of deer infected with it, usually in August and September, and it doesn't affect humans.
The disease used to be confined pretty much to the southwestern part of the state, killed at least 80 deer in Salem County last year, and has hit deer as far north as Morris County. EHD used to occur in 10-year cycles but, like our “100-year floods,” now occurs more frequently.
This year, hunters reported finding dead deer in the Hopewell-East Amwell-Hillsborough-Neshanic area. Outbreaks are caused by the density and distribution of the midges (tiny flies) that carry EHD, not by the density of the deer herd.

Dead dolphins, sea lions found on Oxnard beach; natural neurotoxin blamed
Teresa Camara and her husband, Keith Flanagan, were walking on the Oxnard beach Thursday evening north of Fifth Street when they came across a grisly scene.
"We were having a really good time. We were with our dog, the sun was setting and the weather was beautiful, and then we came up to the first dead dolphin," she said. "And then we found another one, and we looked up and we realized the beach was kind of scattered with dead dolphins."
On Friday morning, volunteers from the Channel Islands Marine and Wildlife Institute found four dead dolphins and four dead sea lions at a site not far from the power plant at Mandalay Beach. "They were all different sizes. Two of the dolphins were smaller and appeared to be younger," Camara said. "We didn't understand what was going on, and we felt very sad for the dolphins."
According to Tom McCormick, a marine biologist who has worked in biological assessment along the Ventura County coast for more than 20 years, the deaths probably are linked to a natural neurotoxin called domoic acid.

[Dead birds appear in another lagoon C. Real for possible botulism outbreak]
(Translation disclaimer)
The occurrence of specimens of dead birds in the lagoon from the Prado in Pozuelo de Calatrava (Ciudad Real), has raised the alarm about the possibility that it is a new episode Avian botulism similar to that too, for days in the lagoon Navaseca in Coldstream.
Sources in the administration of the autonomous region have told Efe that since about a week ago is being detected mortality of birds of different species in this lagoon, which is included in the list of protected areas in Castilla-La Mancha Nature Reserve and Wildlife Refuge. The dead birds are being recalled almost daily vessel lagoon by technical and environmental officials from the Ministry of Agriculture of the Community Board.
The new episode of mass death of birds in a lake The Wet Spot comes days after it had recorded a similar circumstance in the lagoon Navaseca (Coldstream), which then confirmed to Efe as chief of Toxicology and Animal Health Unit of the Institute of Hunting Resources (IREC), Rafael Mateo, it was a case of avian botulism. Lagoon Pozuelo de Calatrava, also known as 'The Unexpected', is just thirty miles of Lake Navaseca, located in the vicinity of National Park Las Tablas de Daimiel.
Experts consulted by Efe today have indicated that the death of birds in these ponds may be related to the same outbreak of botulism, or be a different episode.
