(Practice)Standard Practice for Sampling Zooplankton with Pumps
Standard Practice for Sampling Zooplankton with Pumps
SIGNIFICANCE AND USE
5.1 The advantages of collecting zooplankton with pumps are as follows:
5.1.1 Sample size is more accurately controlled than with nets.
5.1.2 Discrete samples can be more easily obtained both vertically and horizontally.
5.1.3 Multiple or replicate samples can be more easily obtained.
5.1.4 The pumps are adaptable to a variety of ecosystems less than 30 m deep.
5.1.5 Sampling efficiency does not decrease with sample size.
5.2 The disadvantages of collecting zooplankton with pumps are as follows:
5.2.1 Pumps are bulky and require an electrical source.
5.2.2 Pumps are generally more costly than nets.
5.2.3 Pumps generally discriminate against collecting macroplankton.
5.2.4 Pump intake tubes may be avoided by the more motile zooplankton forms.
5.2.5 Requires a long, bulky, intake tube for deep water sampling.
5.3 There are several special considerations that should be observed when collecting zooplankton with a pump. They are:
5.3.1 Some pumps can fragment zooplankton and induce mortality due to their design.
5.3.2 The pump hose must be cleared before taking the next sample.
SCOPE
1.1 This practice covers the procedures for obtaining qualitative/quantitative samples of a zooplankton community by use of pumping systems.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.2 Definitions of Terms Specific to This Standard:
3.2.1 macroplankton, n—macroscopic plankton comprising of the larger planktonic organisms.

3.2.3 zooplankton, n—plankton consisting of small animals and the immature stages of larger animals.
3.2.3.1 Discussion—
Some of these organisms, such as miniature crustaceans and protozoans, are very small. Others, such as jellyfish, are larger. Some
fishes and shellfish begin their lives as eggs or tiny larvae. These eggs and larvae are also zooplankton.
