Lampricide concentrations in larval sea lamprey (Petromyzon marinus) carcasses collected following two TFM and two TFM/Bayluscide treatments were determined to support risk assessments for non-target organisms that may consume lampricide-laden carcasses. Carcasses were removed from the treated streams either immediately after completion of the treatment or 2-days post mortem. The estimated average TFM concentration in the fresh carcasses (n = 80) collected from the rivers was 4.58 µg·g-1 (SEM =1.06 µg·g-1). The average concentration of niclosamide (the active ingredient in Bayluscide) in the fresh carcasses from the two rivers treated with TFM and Bayluscide was 0.492 µg·g-1 (SEM = 0.210 µg·g-1). The mean 2-day...

The lampricide formulation 3.2% Bayluscide® Granular Sea Lamprey Larvicide (gB) is applied at the water’s surface and falls through the water column to the benthic habitat of larval sea lamprey. Knowledge of how gB falls through the water column is critical to effective delivery of the time release formulation. The average sinking rate of gB was determined at a temperature of 15.0⁰C (13.8-16.0⁰C). Water depth did not have a statistically significant effect on gB sinking rate. The average sinking rate was found to be 7.01 cm/sec (0.230 ft/sec) which corresponds to a falling rate of 14.3 sec/meter (4.35 sec/ft). Average time to Bayluscide release is 218 seconds. A model was created to predict how big of a buffer region...
