Sometimes the weather that keeps most of us inside makes for ideal fishing. Not today, I hope. Right now a blizzard is raging with the wind gusting in 53-mph blasts, causing 10 degrees to "feel like" -20. (Fortunately, I'm inside, warmed with coffee, a woodstove, electricity that hasn't blinked yet and the knowledge that I don't have to go anywhere except for brief walks with a dog whose short legs limit him to a short path dug in the snow.)

Blizzards and negative temperatures are also common in Dauphin River in Manitoba, Canada. Located about 430 miles north of Fargo, North Dakota, next to Lake Winnipeg, the area is also home to about 65 commercial fishermen, according to Dale Einarsson whose husband, Helgi, is one of them.

Commercial fisherman Helgi Einarsson uses this under ice crawler to set his nets under frozen Lake Winnipeg.

It's part of a series showing Canada's commercial fishermen at work offered by the council, which was formed in 1995 to promote the country's fish harvesters and represent them at a national level.

Helgi Einarsson's weather challenges are similar to ones faced by all commercial fishermen. As Dale explains, it could be a nice morning when they go out, but conditions change so fast that you can be out there when a snowstorm blows up. "Out there" is on the frozen lake, where they string nets between holes in the ice using a device called an "under ice crawler" to target pickerel and whitefish. To see how it's done, watch the video below.
