Description of ASTM-E1198 2012ASTM E1198 - 87(2012)Standard Practice for Sampling Zooplankton with PumpsActive Standard ASTM E1198 | Developed by Subcommittee: D19.24 Book of Standards Volume: 11.06 ASTM E1198Significance and Use 4.1 The advantages of collecting zooplankton with pumps are as follows: 4.1.1 Sample size is more accurately controlled than with nets. 4.1.2 Discrete samples can be more easily obtained both vertically and horizontally. 4.1.3 Multiple or replicate samples can be more easily obtained. 4.1.4 The pumps are adaptable to a variety of ecosystems less than 30-m deep. 4.1.5 Sampling efficiency does not decrease with sample size. 4.2 The disadvantages of collecting zooplankton with pumps are as follows: 4.2.1 Pumps are bulky and require an electrical source. 4.2.2 Pumps are generally more costly than nets. 4.2.3 Pumps generally discriminate against collecting macroplankton. 4.2.4 Pump intake tubes may be avoided by the more motile zooplankton forms. 4.2.5 Requires a long, bulky, intake tube for deep water sampling. 4.3 There are several special considerations that should be observed when collecting zooplankton with a pump. They are: 4.3.1 Some pumps can fragment zooplankton and induce mortality due to their design. 4.3.2 The pump hose must be cleared before taking the next sample. 1. Scope 1.1 This practice covers the procedures for obtaining qualitative/quantitative samples of a zooplankton community by use of pumping systems. 1.2 This standard does not purport to address all of the safety problems, 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.
