Cutthroat Trout

OPB | Feb. 1, 2004 7:30 p.m.

Scientists don’t know why some cutthroat trout remain in their native streams, while others head out to sea, then return home to spawn. They also don’t know why the ocean-going cutthroats have been failing to return in recent years. Biologists fit the trout with radio tags to find out.
