Scope

1.1 This practice covers the procedures for obtaining qualitative and quantitative samples of macroinvertebrates on an artificial substrate sampler in rivers, streams, lakes, and reservoirs. The device can be used in areas where no other method is feasible.

1.2 Multiple-plate samplers are usually colonized by a wide variety of macroinvertebrates that actively and passively enter the current or the water column.

1.3 This practice facilitates standardization of collection procedures at sampling sites and is excellent for water quality purposes. Standardized sampling is especially desirable when the results from different investigators and from different environments are to be compared.

1.4 Multiple-plate samplers are devices of standard composition and configuration placed in the water for a predetermined exposure period and depth for colonization by macroinvertebrates.

1.5 The multiple-plate sampler can be used either alone or can effectively augment bottom substrate sampling because many of the physical variables encountered in bottom sampling are minimized (for example, variable depth and light penetration, temperature differences, and substrate types).

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautions, see Section 7.
