CONTAINED IN VOL. 11.05, 2001 Specifies surber, portable invertebrate box, Hess, Hess stream bottom, and stream-bed fauna samples are quantitative, qualitative collecting devices, operated by hand, for outlining a unit-area, collecting the macroinvertebrates within it and retaining them. Can be placed by hand onto or into mud, gravel, sand or rubble substrate types, in shallow streams, areas of rivers. Drift net sampler is a quantitative, qualitative collecting device to drifting organisms in flowing waters.

1.1 The Surber, portable invertebrate box, Hess, Hess stream bottom, and stream-bed fauna samples are qualitative and most are reasonably quantitative collecting devices. They are operated by hand. They provide for outlining a definite unit-area, for collecting the macroinvertebrates within the area, and are equipped with a net to retain organisms. They are designed to be placed by hand onto or in some cases into mud, sand, gravel, or rubble substrate types, in shallow streams, or shallow areas of rivers.

1.2 The drift net sampler is a qualitative and quantitative collecting device used to capture drifting organisms in flowing waters.
