Fish Key in on Shrews, Study Finds

“Mousing” has developed a unique following of anglers who head out after dark to draw fish out with big, topwater mouse patterns. And a new study published in the journal Ecology of Freshwater Fish proves the effort may indeed be worth your while.  “This study documents that rainbow trout and grayling actually key in on shrews,” writes Matt Miller, “much as trout will focus on mayflies or caddis flies when these insects hatch.” Via The Nature Conservancy.
