4:23: p.m.: A report from the state shows that some of the fish from the White Park pond had a bacterial infection.

Dead fish found in the White Park pond tested positive for a bacteria formally known as Aeromonas sp., according to Inga Sidor, a veterinary pathologist for the University of New Hampshire. The bacteria is common in freshwater and warm temperatures.

The report stated that the fish suffered from a bacterial infection – not a parasite, as Gill indicated earlier today. The bacteria has only a minimal risk to humans and pets, according to a report from the state Department of Environmental Services.

Additional testing will be done on the pond’s water quality, the report states.

11:46 a.m.: A parasite is killing fish at White Park, according to Concord Parks and Recreation Director David Gill.

“Basically, there was a parasite killing the fish,” Gill said, which explains why dead fish were found floating around the park’s pond this spring.

When dead fish were found last month, initial tests didn’t yield any answers. But the city worked with the Department of Environmental Services and the University of New Hampshire to conduct more tests on the dead fish and discovered a parasite, Gill said this morning.

The city doesn’t stock the pond, officials said last month, so they did not know where the fish came from.

Gill said he’ll release more information later today.
