Hundreds of Dead fish show up in Sask. lakes

Everyone is feeling the heat this summer, even the fish in our lakes.

Hundreds of dead fish have been found floating in Echo and Pasqua Lakes. There have also been reports at Katepwa and Last Mountain Lake.

Gord Sedgewick, a fisheries biologist with the Ministry of Environment explained that only carp and tullibee cisco are turning up dead in huge numbers.

“There is no oxygen below nine meters. So, what’s happening is these cisco are coming up, they have to breathe. So they come up into the warmer water, but it’s too warm for them. Warm water holds less oxygen, but fish in warm water need more oxygen.”

Other species like walleye, perch and jack are adapting, cleaning up hundreds, if not thousands of fish corpses is not easy.

The only way to clear the carp from the waters is to physically remove them because they continue to float, no matter what you do to them. Once removed you can bury them or see if any nearby farmers would like to use the dead fish as fertilizer.

The only other option is to simply leave the dead fish to decompose in the water or leave it up to the birds and other animals.
