Some researchers say global warming will impact fish habitat in the
Great Lakes. Chuck Quirmbach reports:
Some scientists have projected that more global warming will mean less
rain and snow falling into the Great Lakes and the continuation
of low water levels.
Researcher Brian Shuter is with the Ontario Ministry of Natural
Resources. He says if the projection comes true, there will be
more stress on the millions of Great Lakes fish:
“I mean the space for fish to live in is just gonna shrink and the less
space there is, the less fish there will be.”
Shuter also anticipates higher summertime water temperatures and less
ice cover in the lakes. That’s a change that could lead to more warm
water fish like bass and fewer of the cold water fish like salmon
and trout that people like to eat.
Shuter says the change could also promote the growth of invasive
species that favor warmer water temperatures. So, he encourages tighter
controls on invasives and more water conservation programs.
