Four nets submerged in a stream to capture drifting invertebrates

Detailed Description

Sampling drifting invertebrates from a stream in the North Cascades of Washington State. We perform drift sampling to determine the invertebrate prey quality and quantity available for drift feeding fish. Data gathered from this sampling are used in bioenergetics modeling, a method of estimating fish growth potential.
