Benthic In-Stream Samplers
Stream Drift Net
Floating organic material in a stream, or drift,
is sampled with a drift net. This net is mounted on
a frame and placed with the mouth upstream. As drift
moves down with the current, it is trapped to be
examined later to determine composition and amount.
Drift nets are stationary nets for use in streams
and rivers designed to sample organisms from flowing
waters at and below the water surface. Nets can be
used singularly or in groups with the nets placed
side-by-side, anchored to the bottom with stakes.
Frame and stakes are constructed of stainless steel.
Net is durable Nitex® nylon with a 363µm mesh size
and measures 40" long with a net mouth of 12" x 18".
Also available is a floating assembly which attaches
to the top of the net and suspends it in water
deeper than 18". The assembly comes with floating
ring and hardware to attach to the net. The drift
net is supplied with two 18" stakes.
