mercury concentrations in quagga mussels, dreissena bugensis, from lakes mead, mohave and havasu.the recent invasion of the dressenid species, the quagga mussel, dreissena bugensis, into lakes mead, mohave and havasu has raised questions about their ability to alter contaminant cycling. mussels were collected from 25 locations in the three lakes. the overall average was 0.036 +/- 0.016 microg g(-1) hg dry wt. the range of the three lakes was from 0.014-0.093 microg g(-1) hg dry wt. there were no significant differences in mercury concentrations among the three lakes (f = 0.07; p = 0.794). f ...201020224976
quantifying quagga mussel veliger abundance and distribution in copper basin reservoir (california) using acoustic backscatter.quagga mussels (dreissena bugensis) have been linked to oligotrophication of lakes, alteration of aquatic food webs, and fouling of infrastructure associated with water supply and power generation, causing potentially billions of dollars in direct and indirect damages. understanding their abundance and distribution is key in slowing their advance, assessing their potential impacts, and evaluating effectiveness of control strategies. volume backscatter strength (sv) measurements at 201- and 430-k ...201121906773
