Catherine creek lamprey treatments in Finger Lakes Discussion Posted October 8, 2021 · Edited October 8, 2021 by Sk8man The mentioning of Bayluscide is a little misleading. It is actually an additive to TFM which is the main treatment chemical. Bayluscide is readily absorbed by the sediment layer. Bayluscide has also been used on small bodies of water to control Zebra mussels but it is too expensive and impractical to use on large bodies like the Fingers for that purpose. It is also mentioned by DEC that it will "improve fishing" but it should be noted that it will take YEARS before significant impact will be seen because the treatment has no impact on the juveniles and adults roaming the lakes. https://umesc.usgs.gov/documents/publications/2003/dawson_a_2003.html#:~:text=Bayluscide is an additive to TFM that increases,(2'%2C 5-dichloro-4'-nitrosalicylanilide)%2C the active ingredient of Bayluscide%2C degrades Wondering if maybe they treated the Keuka Outlet in June and now doing Catherines?
