Research suggests that anglers will have a tougher time finding good trout fishing in the future.

An American study says climate change will reduce the number of streams suitable for all kinds of trout by nearly half over the next 60 years.

Scientist Seth Wenger at Trout Unlimited says warmer water, altered stream flow and changes in the life cycle of bugs will drive the changes.

He says Canada won't suffer as badly as the U.S., but will still see habitat loss.

Wenger adds that bull trout, Alberta's provincial fish and the focus of government conservation programs, is likely to be one of the worst-hit species.
