Every fish in B.C.'s Emerald Lake may have to be killed after signs of rare parasite detected

Researchers say every fish in B.C.'s Emerald Lake may have to be "sacrificed" after the discovery of a rare parasite in the water.

But first, more testing needs to be done.

Parks Canada says it is investigating a suspected case of whirling disease in Yoho National Park's Emerald Lake.

The disease is a microscopic parasite that affects trout and salmon, and can cause infected fish to swim in a whirling pattern and die prematurely.
