About 400 fish have died off in the past week in Pittock Lake due to the recent heat wave.
WOODSTOCK - Hundreds of fish have died off in the past week in Pittock Lake.
Around 400 Carp fish have died during the recent heat wave. Aquatic Biologist at the Upper Thames River Conservation Authority Michelle Fletcher says this is weather related.
"Water temperatures went up quite quickly, around 16 degrees over 2 weeks and the Carp are spawning right now and it is a huge use of energy for them to do that. So those two stressors combined have made some of them more vulnerable."
The Carp die off every year when they are spawning, however the numbers are higher this year because of the weather.
Fletcher says, they are not alarmed because it is only one species of fish.
"If it was some kind of a spill, then it would be every size class of every species out there. Because it is just the large adult and just the carp, and they are spawning right now, they have been for a little bit now in the lake, that is what the cause is."
