In the present study, navigational buoys were used to monitor Dreissena polymorpha (zebra mussel), an aquatic invasive species in Otsego Lake, New York. Buoys from the north and south sites of Otsego Lake were taken out of the water on December 29 and December 31, 2012, respectively, after being in the water since April 14, 2012. All sampled mussels were frozen until further analyzed; an electronic caliper and compound microscope were used to measure shell lengths. We observed growth, settlement, and density of each colonized buoy and determined that light shielded bottom sides of the buoy had the most colonization whereas the shallowest submersed side had the least. Shell length of mussels from the south site was significantly larger than those from the north site. The mussels from the metal anchor-chain ring at the deepest end of the buoy were the largest, while no difference was found among the rest. Colonization of zebra mussels can be due to specific substrate types and amount of nutrition available in the habitat. Additionally research is recommended comparing buoy designs to determine if buoys without light shielded bottoms will be less colonized.
