Jackson Fish managers conducted their annual sampling of the Snake River near Jackson recently. Biologists sample a different section of the river each year on a three-year rotation. This year they sampled a section between Moose and the Wilson Bridge. Each year, the crew samples the same section three times within a week, weather permitting. And the weather is typically a wild card for this late-season field work as proved true this year, ranging from shirt-sleeve weather to the single digits within the same week. Fish managers spend nearly every summer day in the field, sampling area waters and recording the data. Jackson Fish Biologist, Clark Johnson says biologists found an appreciable number of cutthroats this year which often were 16 inches or greater. With winter, the field work is shut down and the data is analyzed and compared to previous years to get a picture of which way fish populations may be trending.
