If fish is to be consumed uncooked, killing the parasites requires it to be frozen at -20 C for at least a week, Young said. Most commercial sushi-grade seafood suppliers freeze at -40 C.

Lichens can provide valuable information about air quality and environmental conditions, as different species have different sensitivities to pollution and humidity levels, making them useful indicators of climate and pollution levels in a given area.

The river, which starts at the Saskatchewan Glacier in the Columbia Icefields and flows through to central Saskatchewan, is usually murky brown by the time it reaches Edmonton in summer. In recent weeks, however, the water has taken on the hues of Alberta's glacial lakes, thanks to dry, hot weather combined with maintenance at a major dam.
