1、Designation: D4211 82 (Reapproved 2012)Classification forFish Sampling1This standard is issued under the fixed designation D4211; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses in

2、dicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This classification covers rotenone and antimycin whichare used to collect or eradicate fish; numerous chemicals havebeen used but presently only rotenone and

3、antimycin are EPAapproved for this use.2. Referenced Document2.1 ASTM Standards:2D4131 Practice for Sampling Fish with Rotenone3. Significance and Use3.1 The significance of using chemical fish toxicants is thatmore complete population analyses or total eradication, orboth, can be accomplished. Targ

4、et species can be selectivelyeradicated by varying concentrations. This provides a veryeffective tool in fisheries investigations and managementprograms. Water conditions (that is, pH, temperature,alkalinity, and so forth) and morphology can be limitingfactors.3.2 RotenoneRotenone used as a fish tox

5、icant is highlyversatile and can be used effectively to collect fish samples; toeradicate fish; and to selectively remove certain fish species.3.2.1 Its effectiveness is reduced in cold 20C, and dosagerequired increases with alkalinities. It may also eliminate foodweb organisms. Fish may be repulsed

6、 from treated areas.3.3 AntimycinAntimycin is versatile in the selective re-moval of scalefish or even more selectively against certaincentrarchids (sunfish) and minnows.3.3.1 Its effectiveness is reduced in water with pH above8.5.4. Basis of Classification4.1 EPA-Approved Fish Toxicants.4.1.1 Roten

7、oneThis fish toxicant is also known as derrisor cube and is derived from roots of several plants of the familyLeguminosae. Its action mode as a powerful respiratory inhibi-tor in fish starts with entrance into the blood stream via the gillsand then by translocation to vital organs. Formulations are

8、inthe following general forms: a liquid containing 5 % rotenone,liquid with 2.5 % rotenone and synergists, and wettable pow-der. Persistence in the environment is seldom more than twoweeks although it may remain longer in very cold, soft water.4.1.2 AntimycinThis fish-toxicant is an antibiotic pro-d

9、uced by Streptomyces and is known as Fintrol 5, Fintrol15, and Fintrol-Concentrate. The Fintrol 5 and 15 arecoated sand-like grains for use in waters 5 to 15 ft (1.52 to 4.57m) deep. The Fintrol-Concentrate is a liquid for use instreams or shallow waters. Antimycin is effective in smallconcentration

10、s (5 ppb) and enters fish through the gills toirreversibly block cellular respiration. It is nonpersistent in theenvironment.ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard.
