"For the first time in 4½ years, a healthy adult Atlantic whitefish has been discovered in its lone refuge outside Bridgewater, N.S.

The critically endangered relative of the Atlantic salmon — a 33-centimetre female — was found in a fish trap on Dec. 7, ending a worrisome drought.

No adults had been seen alive since the arrival of chain pickerel, a voracious invasive species that has become established in two of the three lakes that make up the Petite Riviere watershed — the only place on the planet where the Atlantic whitefish survives."
