Biologists with the Idaho Department of Fish and Game are puzzled over the dropping numbers of trout in the South Fork of the Snake River.
The Idaho Falls Post Register is reporting
that trout numbers near Conant and Lorenzo dropped 32 percent and 35 percent, respectively, during this year's tracking by Fish and Game biologists who use electro-fishing gear. In both cases, the Post Register
reports, the trout population dropped from near-record highs to numbers that were closer to the long-term average at both locations.
"This year's data is kind of an outlier, and it has us scratching our heads a bit," said Brett High, the department's point person on the South Fork. "We are trying to figure it out."
But biologists are quick to add that they don't want to "paint the picture that the sky is falling."
"Populations ebb and flow," said High. "And we are in one of the downturns. Still, it is a bit puzzling."
