1.1 本指南涵盖了鱼类致死和非致死采集方法的使用。 1.1.1 致命做法包括使用鱼藤酮和抗霉素来采集或根除鱼类；已经使用了许多化学品，但目前只有鱼藤酮和抗霉素被美国环境保护局（EPA）批准用于此用途。 1.2 非致命性采集做法通常不会导致鱼类死亡。 1.2.1 非致命做法包括水面或河岸观察、水下观察、刺网、海滩围网、环网、fyke网、诱捕网、电击、小鱼诱捕器、围栏（弹出式投掷）诱捕器、垂钓者调查、商业调查。 1.3 本指南的重点是提供鱼类采集的采样实践。本标准不包括物种鉴定或采样数据的任何统计方法。 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。 有关本程序中使用的所有化学品，请参阅MSDS。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 鱼类采样包括许多致命和非致命做法。 4.2 本指南概述了常用的鱼类采样实践。 4.3 本摘要简要说明了负责确定鱼类采样实践或最符合采样目标的实践的人员可用的选项。

1.1 This guide covers the use of lethal and non-lethal collection practices for fish. 1.1.1 Lethal practices include the use of rotenone and antimycin which are used to collect or eradicate fish; numerous chemicals have been used but presently only rotenone and antimycin are U.S. Environmental Protection Agency (EPA)-approved for this use. 1.2 Non-lethal collection practices typically do not cause mortality to fish. 1.2.1 Non-lethal practices include surface or bank observation, underwater observation, gill netting, beach seines, hoop nets, fyke nets, trap nets, electroshocking, minnow traps, enclosure (pop drop and throw) traps, angler surveys, commercial surveys. 1.3 The focus of this guide is to provide sampling practices for fish collection. This standard does not cover the identification of species or any statistical methods for the sampling data. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. Refer to the MSDSs for all chemicals used in this procedure. 1.6 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 ====== 4.1 Fish sampling includes a number of lethal and non-lethal practices. 4.2 This guide provides an overview of commonly used fish sampling practices. 4.3 This summary serves as a brief accounting of options available to personnel responsible for determining the fish sampling practice or practices that best serve the sampling objectives.
