Surber Samplers are used for quantitative
analysis of benthic stream organisms and can be used
in shallow streams less than 18" deep with a range
of bottoms from silt to large cobble. The sampler
consists of a 12" x 12" horizontal frame that sets
on the stream bottom to border the sampling area and
is used to stir up the bottom sediments and
invertebrates. The standard size net measures 9"
diameter and 24" long and is attached to the
vertical frame to catch the benthic invertebrates
and sediments as the horizontal frame is agitated
and they flow into the net. Nets are available in
rugged Nitex nylon in four mesh sizes. Optional base
extensions that attach to the bottom of the frame
are available for use in areas of fine sediments to
allow the operator to minimize movement of organisms
outside of the sampling area. All samplers include
