1.1 本规程涵盖了使用泵送系统获取浮游动物群落定性/定量样本的程序。 1.2 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 这个 优势 用泵收集浮游动物的方法如下: 5.1.1 与使用网相比，样本量得到了更精确的控制。 5.1.2 可以更容易地在垂直和水平方向上获得离散样本。 5.1.3 可以更容易地获得多个或重复的样本。 5.1.4 这些水泵适用于30以下的各种生态系统 m深。 5.1.5 采样效率不会随着样本量的增加而降低。 5.2 这个 缺点 用泵收集浮游动物的方法如下: 5.2.1 泵体积庞大，需要电源。 5.2.2 泵通常比网更贵。 5.2.3 水泵通常不利于收集大型浮游动物。 5.2.4 更具运动性的浮游动物形式可以避免泵吸入管。 5.2.5 需要一个长而笨重的进水管来进行深水采样。 5.3 使用泵收集浮游动物时，应注意以下几个特殊事项。他们是: 5.3.1 一些水泵的设计会使浮游动物破碎并导致死亡。 5.3.2 在采集下一个样本之前，必须清理泵软管。

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. ====== 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.
