Thanite: A Fish Management Tool in Southlands Experiment Forest Ponds

Thanite (82% isobornyl thiocyanoacetate) has been used as a fish management tool on International Paper Company's Southlands Experiment Forest since 1968. Annually, Experiment Forest personnel successfully move 2.000 to 4,000 largemouth bass (Micropterus sa/moides) with an 0.8 to I ppm (active ingredient) mixture of 80%Thanite - 20% Atlox 1045-A. Collection and survival percentages are higher when water temperatures are less than 70°F. Collected fish are placed in cans of untreated water in collection boats and later transferred to an aerated holding tank. Recovery in the tank is usually rapid and survival exceeds 90%.
