Mechanism of Action 

The active ingredient of FINTROL is antimycin A. When absorbed through the gills 

of fish, antimycin A kills by interfering with the respiration of body· cells. Antimycin A 

does not repel. fish . This is an important"advant;:1ge, particularly when running waters, 

bo·g lakes, and the epilimnion, or upper layer of large lakes are treated. Fish make 

no attempt to escape contact with the toxicant by seeking to move into waters that 

are clear of it. FINTROL'S action is rapid arid Irreversible. 

10 
( 

Fintrol® Fish Toxicant Kit EPA Reg. No. 39096-2 December 27, 2012 

Sensitivity to FINTROL varies widely among fish species. Hence it may be employed 

to selectively destroy certain species, without affecting other species concurrently 

inhabiting the same body of water. 

Sensitive: 

. . ' .Gizza.rd shad, trouts, pikes, carp, minnows, sucl<ers, brook stickleback, white . 

bass, sunfishes, perches, freshwater drum, sculpins. · · 

Least Sensitive: 

Shortnose gar, bowfin, goldfish, catfish. · 

FINTROL also may be used to selectively destroy certain age groups of species; 

younger fish are more sensitive to FINTROL. 

Providing the concentration is correctly estimated, FINTROL can be used effectively at 

·any time of year in· either cold, warm, soft, hard, acid, alkaline, clear or turbid '(muddy) 

waters. (See TABLE 1 and instruction for bioassay.) 

FINTROL does not impart detectable taste or odor to treated waters. In the usual, 

recommended concentrations, it cause~ no apparent harm to aquatic plants, insects, or 

bottom fauna. Since FINTROL'S active ingredient degrades rapidly, the reclaimed 

waters may be restocked soon after treatment. (See HOW TO DETERMINE WHEN 

TREATED WATER MAY BE RESTOCKED.) There is very little interruption in 

availability of the waters for recreational, agricultural, industrial, or other purpose. 

Complete and Selective Kills 

This product may be used to achieve a 'complete kill' or a 'selective kill.' Complete kills 

are intended to eliminate all fish in the treatment area whereas selective kills, used only 

in aquaculture, are intended to eliminate or reduce the number of only certain (more 

vulnerable) species. Detailed instructions for conducting complete and selective kills 

· are presented in the antimycin A SOP Manual and are summarized below. 

A complete kill may be achieved with a concentration of anywhere from 5 to 25 

p.p·.b. of active ingredient (See HOW TO DETERMINE THE MOST EFFECTIVE 

CONCENTRATION.) FINTROL is particularly advantageous for complete kills 

because if detoxifies so rapidly the pond can usually be restocked in about a week, or 

as soon as caged fish survive 48 hours' exposure to the treated waters. 

Under optimal circumstaf"lces, in ponds managed for sports fishing, selective kills 

may be achieved at concentrations as low as 0.5 to 1.0 p.p.b. However, because 

these concentrations are extremely low, there is no rule of thumb that can be relied 

liPOn to determine them accurately. A BIOASSAY IS ALWAYS REQUIRED TO 

PINPOINT THE OPTIMAL CONCENTRATION FOR SELECTIVE KILLS. 

11 
( r '· . ~ I t.O 

Fintrol® Fish Toxicant Kit EPA Reg. No. 39096-2 December 27, 2012 

A selective kill has these advantages: It can be made without interrupting sport 

fishing for· more than a week or so, and fishing may be gradually improved without 

restocking. In the past, when bluegill, minnows, or green sunfish dominated a pond 

managed for bass, the usual solution to the problem was the total removal of all the 

fish with a fish toxicant This meant restocking and little or no fishing for one or two 

years. Now--- with FIN T R 0 L --- this is no longer necessary. Low concentrations 

of FINTROL will affect small bluegill, green sunfish, and minnows primarily. Only a 

few of the very small bass will succumb. The bulk of the adult bluegill and green 

sunfish will not be affected. Thus FINTROL helps to bring about a balanced 

relationship between the bass and bluegill populations. This improves fishing without 

interrupting it for any appreciable length of time of time. · 

In catfish farming FINTROL can be used to selectively eliminate the trash fish (scale 

fish) that commonly redu.ce the y.ields and increase the costs of the commercial .catfish 

farmer. It ispossible to do this with FINTROL because concentrations that will 

eliminate scale fish generally will not harm adult catfish . The scale fish most often 

encountered by the catfish farmer will succumb to anywhere from 5 to 10 p.p.b. of 

active ingredient (See TABLE 1) whereas, under ordinary circumstances,· it takes in 

excess of 20 p.p.b. to kill catfish. (Caution should be exercised.during stress 

conditions of unusually high water temperature and reduced o)(ygen content when the 

sensitivity of fishes to chemical may increase.) .I

How to Determine the Most Effective Concentration . . 

The nature of the water to be treated (its depth) and rate of flow) and the character of 

the surrounding land are factors to be taken into consideration when determining the 

formulation of FINTROL to. employ in a given situation. 

1. Complete kills 

The concentration of. antimycin A required to kill one or more species of fish in any 

given body of water depends upon: I) the sensitivity· of the species to be eradicated, 

and 2) the chemical and physical properties of the water at the time of application of 

the· toxic.ant; the pH and the temperature of the water are the most important of these · · 

chemical and physical factors .under ordinary circumstances. Therefore, to determine 

what concentration of antimycin A will be required to kiil the undesirable fish in your 

pond or lake: · 

1) identify the species to be eradicated, 

2) determine the pH and average water temperature by measuring at various 

sites and depths, 

. 3) refer to TABLE 1 for approximate concentrations. 

4) conduct a bioassay to pinpoint the optimal concentration. 

TABLE 1 provides a ·rough estimate of the concentrations required for a complete 

kill under various environmental conditions. However, since water chemistry is 

subject to sudden alteration by many variables and often unpredictable factors 

(pollution, heavy algae bloom, weather, drawdown, etc.) it should be realized that 

such changes may affect the performance of the toxicant. For this reason, 

· measurements of pH and water temperature sho~:Jid always be taken as close to the 

time of treatment as is feasible.

Fintrol® Fish Toxicant Kit EPA Reg. No. 39096-2 . Oecember·27, 2012 · 

The sensitivity of the target species determines the concentration range. To 

eradicate sensitive species, it is recommended thatthe appropriate formulation at 

FINTROL be applied so that the body of water will have a concentration of from 5 to 

10 p.p.b. of antimycin A; depending upon variation on in pH and water temperature. 

For more tolerant species, higher concentrations are recommended. Laboratory 

Studies indicate that less sensitive fish will succumb at concentrations of from .15 to 

25 p.p_b of antimycin A, depending upon variations in pH and water temperature. 

Columns 3 to 6 show how to adjust for pH and water temperature_ Note that, in 

general, the lower ·the pH, the less FINTROL required. The higher the water 

temperature, the less FINTROL required. The ideal situation for a complete kill 

would combine a highly sensitive species, low pH and ·high water temperature. 

2. Selective Kills 

The only way to determine the concentration of FINTROL needed for a selective kill 

is to perform a bioassay. This involves subjectin.g both the target and nontarget fish 

to several concentrations of FINTROL to determine the minimum lethal dose. 

(A description of the bioassay procedure is available upon request.) 

How to Calculate Amount of Fentrol to be Added to a. Body of Water to Obtain a . 

Given Concentration of Antimycin A 

To calculate the amount of FINTROL to be added to a body of water for eradication of 

undesired species, the following steps should be taken: 

1. Determine the· volume of water to be treated in acre-feet. This can be arrived at 

by multiplying the surface area in acres by the average depth in feet. 

2. Determine the concentration to be used from Table I. 

3. Multiply the number of acre-feet by the value given in Table 2, opposite the 

desired concentration. 

4. The value obtained for volume may be divided by the total kit volume (480 cc. or 

16 oz.) to get number of Fish Toxicant Kits needed.

Methods of Application 

IMPORTANT: Review guidelines in these instructions for use of Pers·onal Protective 

· Equipment {PPE) 

Liquid formulation: Directions for mixing: Add the Diluent (blue label] to the 

FINTROL CONCENTRATE (solution 23%) [Green label] in the oversize mixing 

container. Cap tightly and invert 2 to 3 times to mix thoroughly. Further. dilute with 

AT LEAST five (5) gallons ofwater to insure that the aceto11e contained in 

FINTROL-CONCENTRATE will not affect rubber parts on any equipment that might 

be used to apply it. After water has been added, apply within eight (8) hours. (Note: 

The solution obtained by mixing the Diluent with FINTROL-CONCENTRATE 

(solution 23%) retains potency for up to seven (7) days. But once water has been 

added to this solution, it must be used within eight (8) hours to ensure potency.] 

After appropriate dilution with water, the liquid formulation of FINTROL can be applied 

to lakes and ponds by the boat bailer method or' spray equipment. Spray methods 

are useful at depths to one foot.· Boat bailer and drip tubes when applied at the 

propeller wash are useful at greater depths. Pinpoint applications to shoal areas 

and small, isolated ponds can readily be made with backpack sprayers. (See 

CAUTION on use of PROTECTIVE GOGGLES AND PROTECTIVE GLOVES.) 

In streams, FINTROL-CONCENTRATE is most often applied through drip stations 

established to meter the toxicant at a precalculated rate. Information on the use of 

such equipment m·ay be obtained from state and/or. federal agencies, experienced 

in strearn treatment. 

[t is recommended that all applications of FINTROL be made at daybreak or as soon 

as there is enough light to work by. 

Potency of Mixed'Formulations 

Leftover portions of mixed liquid formulation retain potency for up to seven (7) days. 

But once water has been added to FINTROL-CONCENTRATE, it must be used within 

eight (8) hours to ensure potency. 

Ho~ to Determine When Treated Water May be Restocked 

. . 

Since antimycin A degrades rapidly following application, waters can usually be 

restocked about one week following treatment with FINTROL. Place live cars 

containing a sensitive species of fish in the treated water. Use fingerling rainbow trout 

or fingerling bluegills if the water temperature is between 35 and 68F. When the water 

temperature exceeds 68F, use only fingerling bluegills. If the fish survive for 48 hours, 

. the water may be restocked. 

Deactivation With Potassium Permanganate (KMn04) 

17 
c· ( 

Fintrol® Fish Toxicant Kit EPA Reg. No. 39096-2 December 27, 2012 

Flow in a stream and outflow from a treated lake beyond the treatment area must be 

deactivated with potassium permanganate to minimize exposure beyond the treatment 

area unless unnecessary. (See the AntimyCin A SOP Manual for the definition of 

treatment area, examples when treatment with potassium permanganate is 

unnec~ssary and detailed· guidance for deactivating antimycin A with potassium 

permanganate,) · 

To prevent killing fish downstream, apply potassium permanganate at 1 part per 

million (1 p.p.m.) to the outflow. (More potassium permanganate may be needed if 

the stream has a high permanganate demand. Drip systems of hose-and-clamp or 

carburetor types can be employed to continuously dispense a solution of potassium 

·permanganate into the water at the discharge outlet. · 

To evaluate the effectiveness of the detoxification process, place livecars contain ing 

fingerling rainbow trout or fingerling bluegills approximately 100 yards downstream 

· from the site of KM n 0 4 introduction. The water is considered detoxified if the fish 

survive for at least 48 hours in the livecar. · 

To detoxify FTNTROL-treated streams, apply KMn04 at 1 p.p.m. at detoxification 

stations. (More K.Mn04 may be needed if the stream has a high permanganate 

demand). Continue the application KMn04 until all FINTROL-treated water has 

passed the station. The water may be considered detoxified when fingerling rainbow 

trout or fingerling bluegills survive for at least 48 hours in livecars place 100 yards ·. · 

downstream from the site of potassium permanganate (KM n04) introduction. 

Re-entering The Treatme·nt Area 

For the first 7 days after treatment, handlers re-entering treated w~ter m~st wear, at a 

minimum, the following PPE: 

• Waders and long-sleeved shirt, 

• chemical-resistant gloves, and 

• protective eyewear. 

Special Instructions Regarding State Government Regulatory Agencies 

Prior to the use of a fish toxicant in either public or private waters, the Director of the 

State Fish aod Game Department or Conservation Department must be contacted to 

determine yvhether a permit is required . .Such products must be used by or under the 

technical supervision where required , of personnel of state and federal fish and game 

agencies, .trained in fisheries management, who will provide any special instructions 

applicable to the particular geographical area. · ·
