organisms. Sampling of this sort, where there is no
need or attempt to determine population numbers is
called qualitative sampling.

The HatchMatch is a two-compartment seine,
perfect for quick and easy checks of stream water
quality and insect life.
Collapsible and lightweight, the HatchMatch
measures 10 inches wide and 16 inches high and in
its carrying bag weighs approximately 1.2 pounds. It
can be comfortably transported in a field vest.
When
placed in a stream to a depth of 12 inches to 14
inches, its upper compartment collects insects on
the water surface and from the upper few inches of
stream flow while the lower compartment samples
insects from deeper depths and stream bottom.
Color of the seine provides for high visibility
when examining insects and the mesh allows rapid
flushing of debris and insects from the seine when
sampling is complete. Fabric components are
constructed of mildew-resistant materials and the
frame is molded plastics.
