Water Levels and Lake Temps affect fish
May 1st, 2010 at 3:39pm
With the water levels low and the lake temperature rising some experts advise to watch for affects on fish habitat...

"In June 2007, waterfront residents and boaters on Lake Scugog were finding that carp had begun dying. Residents around the lake were finding massive numbers of dead carp floating and landing on shore. The Carp were dying from an unknown cause. The smell of rotting fish was everywhere. The local authorities allowed dead Carp pick-up days to keep the smell down. After MNR testing, it was suspected that the bacteria columnaris was one of the causes of this massive carp massacre. However, the Koi Herpesvirus, an introduced disease affecting the carp family, was utimately determined to be the culprit. Few carp deaths have occurred since, and in 2008, it was reported that the Lake had returned to its normal state ."

..."The Koi herpesvirus virus causes disease and death when water temperatures are between 18 to 28C. Disease outbreaks are rare when water temperatures are lower than 13C. Fish are most susceptible when stressed as a result of fluctuating high water temperatures, crowding, spawning, etc.."
