1、Designation: D4131 84 (Reapproved 2014)Standard Practice forSampling Fish with Rotenone1This standard is issued under the fixed designation D4131; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number

2、in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers determination of the quantitativeand qualitative species composition of fish in a specified area.The successful use of th

3、is technique is dependent on: (1)preventing fish from escaping the sample area and (2) retriev-ing all affected fish, which may take up to three days.1.2 Advantages:1.2.1 Easily detoxified.1.2.2 All native freshwater fish are susceptible, but it haslow toxicity to mammals and birds.1.2.3 At low conc

4、entrations fish toxicity depends onspecies, age, and size.1.2.4 The suffocating action is reversible.1.3 Limitations:1.3.1 It is less effective in cold (below 20C) and highlyalkaline water.1.3.2 Smaller fish and those without air bladders usually donot float.1.3.3 Completely random selection of samp

5、le areas is notpossible.1.3.4 Overkill beyond sample area can sometimes occur.1.3.5 Food web organisms may be eliminated.1.4 Applicationsthis practice is useful in both short- andlong-term studies for management and impact assessmentpurposes. It is adaptable to both lotic and lentic situations inlit

6、toral and limnetic areas.1.5 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.6 This standard does not purport to address all of thesafe

7、ty concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.

8、s:2D1193 Specification for Reagent Water3. Summary of Practice3.1 The sample area is blocked off with a small mesh net(s)and the volume of water to be treated is calculated.

Procedures7.1 In lakes and reservoirs, fish samples can be obtained ifthe block-off net is long and deep enough.7.1.1 Four to six people and two boats are usually requiredto conduct a 1-acre (4046 m2) survey. The selected sample

18、areais first secured and delimited with the block-off net(s). Verifythat the nets are securely on the bottom with SCUBA divers orif shallow by walking along the net. The volume of water to betreated is calculated from the net perimeter and the average ofseveral depth readings through the area.7.1.2

19、The target concentration of rotenone in the samplearea is _ oz (0.5 to 2.0 mg/L) depending on water conditionsand whether a partial or complete kill is required (0.5 to 2 gal(1.89 to 7.57 L) 5 % liquid per 3 acre-ft will give thisconcentration). Mix the required amount of rotenone in a tuband dilute

20、 it with enough water to disperse uniformly over thesample area.7.1.3 Applied first along the block-off net(s) by pumpingthrough a weighted perforated hose or by a venturi siphonattached to the outboard motor. The remainder of the cove istreated in a zigzag pattern. In shallow waters it can be poure

21、dinto the prop wash.7.1.4 When fish start to surface, collect fish as quickly aspossible, or they will sink and may be lost.7.1.5 Detoxify by dispersing potassium permanganate equalto the rotenone concentration in the same manner as therotenone. Avoid dispersing excessive quantities of potassiumperm

22、anganate because it is also toxic to fish.7.2 In flowing streams and small rivers, fish samples can betaken, but as the size and volume increases, so does thecomplexity of the operation.7.2.1 Initial procedures are as explained in 7.1.1 and 7.1.2except two or more additional people are needed, diver

23、s are notusually necessary, and the block-off net is placed across thedownstream edge of the sample area.7.2.2 Apply the rotenone by pumping through a perforatedhose that is laid on the bottom across the stream at the upstreamedge of the sample area. The pump and rotenone supply can beon shore or in

24、 an anchored boat. In shallow streams rotenonecan be poured along the upstream edge. As soon as thetreatment begins, several floating plastic jugs are released inthe water to visually mark the progress of the rotenone slug.When rotenone has been dispensed, several more floating jugsare placed in the

25、 water.7.2.3 Collect surfacing fish in the downstream section andin front of the block-off net. Keep the net as free of debris aspossible. When the first floating jug reaches the net, disperseequivalent potassium permanganate concentration along thedownstream side of the block-off net until the last

26、 jugs havereached the net.7.2.4 Refs (3), (4), (5), and (6) are provided which give adetailed description of the process and equipment needed totake rotenone samples in streams up to 600 ft (183 m) acrossand 5000 ft3/s (141.6 m3/s).REFERENCES(1) Schnick, R.
