Lake Erie and Lake Michigan zebra mussel settlement monitoring and implications for chlorination treatment
- Sargent and Lundy, Chicago, IL (US)
This paper reports on the 1991 zebra mussel veliger settlement monitoring program undertaken to record and evaluate zebra mussel veliger settlement in Lake Erie and Lake Michigan. Studies by Dr. Gerald Mackie of Canada in 1990 indicated veliger settlement may be occurring primarily during short time periods every season corresponding with warmer water temperatures. Veliger settlement monitoring was performed using a plexiglass sampler apparatus. The samplers were simple in design and consisted of a 20-inch-square plexiglass base panel with thirty-six 1 inch {times} 3 inch clear plexiglass microscope slides attached. The results of the monitoring program indicate the existence of preferential settlement periods for veligers correlating with sustained lake water temperatures above 70{degrees}F. Veliger settlement concentrations in the south basin of Lake Michigan appear to be similar to those in western Lake Erie.
