  • daily settlement rates of the zebra mussel dreissena polymorpha on an Artificial Substrate correlate with veliger abundance
    Canadian Journal of Fisheries and Aquatic Sciences, 1994
    Co-Authors: Andre Martel, Andrea F Mathieu, Scott C Findlay, Stephen J Nepszy, Joseph H Leach

    Abstract:

    The relationship between daily settlement rates and local concentrations of veligers of the zebra mussel, Dreissena polymorpha, was investigated using plankton sampling and scouring pad collectors. A total of 102 plankton and 136 collector samples were taken from a nearshore site near Wheatley, Ontario, in west-central Lake Erie, over 17 consecutive d in August 1992. Results demonstrate a strong correlation between daily settlement rates and daily concentrations of late-stage (competent) veligers in the water column (determined at shell lengths ≥ 170 μm; r = 0.93–0.98; p < 0.001; log10-transformed data). Variations in settlement rates of 1–3 orders of magnitude occurred within 24–96 h. Results also suggest that wind-induced hydrodynamics can affect settlement rates of zebra mussel larvae; the period used to monitor settlement (24 h) was much shorter than that employed (~1–2+ wk) in previous studies. Daily monitoring of concentrations of late-stage veligers in the water column as well as settlers (fibrous ...
