As they travel, the parrs, or young freshwater salmon, undergo a profound transformation called smoltification, becoming smolts able to thrive in saltwater.

Each year, Maine’s Department of Marine Resources and United States Fish and Wildlife Service stocks the rivers and streams with millions of salmon eggs and fry and thousands of parr and smolts.

It’s a name on a parr with Julian, for flaccid pretension.

The project has stocked hundreds of thousands of juvenile salmon, which are called parr.

Even in the second year after DDT enters a stream, a foraging salmon parr would have trouble finding anything more than an occasional small stonefly.
