Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations another old fish article

In the article above we have someone, and likely not a expert, writing about a subject where they only present part of the story. Disadvantages are not known or ignored (bias).

Fintrol is not readily available like rotenone compounds. My understanding is antimycin aka fintrol is primarily available to or used by state and government agencies. Not sure why, but most of the reasons are noted below.

Here is what KY Extension service (Forrest Wayne)says about Fintrol.
"" Fintrol is added to the pond at a rate of 5 to 10 parts per billion (ppb) of active ingredient, depending on the water temperature and pH. This chemical will not kill bullhead catfish.

Fintrol is registered by FDA to use in food fish ponds and is now registered with the KDA Division of Pesticides to use in Kentucky. The chemical is expensive! One unit of Fintrol costs approximately $400.00. A unit will kill scaled fish in 7.5 acre feet of water at a treatment rate of 5 ppb provided the water temperature is greater than 60oF and the pH is less than 8. The pond treatment I assisted with required four or more units.

Fintrol uses acetone as a diluent and a detergent surfactant. These chemicals must be mixed together first than diluted in about 10 gallons of water per unit. The chemical can be dispersed into the water through the boat�s prop-wash via a chemical tank or barrel, a 12 volt bilge pump and a section of hose. Fintrol is a restricted use pesticide. In Kentucky, you will need a private pesticide applicators license to buy it and apply it legally on your own property. Gloves and goggles must be worn while mixing and applying the chemical. The chemical is extremely flammable, is a poison and it smells bad. Fintrol binds to the heme portion of the hemoglobin in the fish�s blood and interferes with oxygen uptake thus killing the fish. Aerators should not be run during treatment as this will prematurely break down the chemical.""
