The Effingham County Emergency Management Agency has issued a fishing and swimming advisory for the Ogeechee River.

The Savannah Morning News reports the agency said Thursday a dead catfish was pulled from the river about 10 miles south of the Ga. 119 bridge along the Sandhill road area over the holiday.

The catfish was blistered, leading officials to conclude it had the bacterial disease Columnaris, which is the same bacteria in the large fish kill last year in the Ogeechee.

Officials say the bacteria are ordinarily present in water, but become a problem when fish are stressed by other factors.

Residents are advised not to swim, fish or eat fish from the river until further notice.
