An evaluation of artificial substrates for monitoring the quagga mussel (Dreissena bugensis) in Lake Mead, Nevada–Arizona

Detachment rates of dreissenid mussels after boat hull-mediated overland dispersal

“…However, a flow through system was used and strong dilution of dissolved zinc limited potential impact of this toxic metal. Previous research on preference of attachment to various materials showed no difference in attachment between fibreglass and aluminium for both the quagga (Mueting et al, 2010) and zebra mussel (Marsden & Lansky, 2000). In our study, both species attached more to fibreglass than to aluminium.…”

“…In our study, both species attached more to fibreglass than to aluminium. Mueting et al (2010) and Marsden & Lansky (2000) looked at the attachment preference of larvae, whereas in the presented experiment adult individuals were used. Thus, there appears to be an attachment preference difference between adults and larvae for both quagga and zebra mussels.…”

“…Mussels must be able (1) to attach to the boat hull (or other submerged parts such as an anchor, outboard motor or trailer), (2) to survive air exposure and prevent desiccation during overland transport and (3) establish a viable population either after detachment or release of spat during launching or sailing. The zebra and quagga mussel attach to a wide variety of materials (Ackerman et al, 1992(Ackerman et al, , 1995Marsden & Lansky, 2000;Kobak, 2004;Mueting et al, 2010), including commonly used materials for the construction of boat hulls such as aluminium and fibreglass (Marsden & Lansky, 2000;Mueting et al, 2010;De Ventura et al, 2016).…”

Veligers of Invasive Quagga Mussels (Dreissena Rostriformis Bugensis, Andrusov 1897) in Lake Mead, Nevada—Arizona

“…In an independent study, it was found that very low settlement of juveniles in the hypolimnion occurred throughout a year-long period (Mueting et al 2010). Therefore, most of the veligers observed in the current study might come from the metalimnion and some from the epilimnion, although this needs to be confirmed in further experiments by sampling veligers at different depths.…”

“…A bimonthly substrate monitoring project on quagga mussel veligers showed that the settlement rates recorded from December 2008 to January 2009 and from October to November 2008 were 45,264 and 28,926 settled juveniles/m 2 , respectively, whereas the settlement rates from August to September 2008 and from February to March 2009 were only 8,062 and 15,719 settled juveniles/m 2 , respectively (Mueting et al 2010). The time when higher settlement rates occurred corresponded to the period when higher percentages of pediveligers were observed in the current study (Fig.…”
