“…Densities of zebra mussels on uncoated plates immersed during one growing season (4-5 months) were within the range of that reported in other colonization studies using plate collectors (de Lafontaine et al, 2002;Kobak, 2005), or an order of magnitude lower (Marsden & Lansky, 2000). The colonization rate and the abundance of zebra mussels on uncoated plates varied between sites and years and were extremely low at the Montreal marina site (MON2000) and absent at Ile Perrot site (IPE2000) where presumably local factors may be limiting for zebra mussel colonization.…”

“…A monolayer of zebra mussels was always observed on the coated plates while very few mussels were occasionally attached to conspecifics on the uncoated plates. As previously described in de Lafontaine et al (2002), zebra mussels tend to aggregate more at the center than near the edges of the coated plates. Probably as a result of higher densities, mussels were distributed more homogeneously on the uncoated plates.…”

“…Antifouling effectiveness was determined in 4 in situ experiments conducted in 4 different years using multi-plate collectors as previously described and used for zebra mussel colonization experiments by de Lafontaine et al (2002). Each experiment consisted in a series of multi-plate collectors submerged for a period of 4-5 months during the summer and autumn months (June-October), at sites in the St. Lawrence River (Canada) where zebra mussels are established (Table 1).…”

“…However, the long term effect of surface colour may be reduced as biofilms develop (Swain et al, 2006). In a previous study examining the performance of a chitin-based coating (de Lafontaine et al, 2002), it was hypothesized that higher degree of substrate roughness may enhance the fixation and settlement of zebra mussels on collectors plate. The results of the present study did not confirm this hypothesis, as the abundance of zebra mussels on rough substrates (sand and 15% chitin coatings) was not significantly different than that on smooth substrates (uncoated and epoxy coatings) (Figure 2).…”

“…Marine sponges are typically unfouled by macroorganisms, and the potential antifouling capacity of natural products isolated from sponges was found to be effective against zebra mussel (Diers et al, 2004(Diers et al, , 2006Bowling et al, 2010). On the hand, chitin, an extract from the exosqueletton of crustaceans, was not useful to significantly reduce biofouling by zebra mussels (de Lafontaine et al, 2002). Overall, the broad effectiveness of these naturally occurring antifouling products has not yet been reported (Chambers et al, 2006;Webster & Chisholm, 2010).…”

The fouling of hard substrates by zebra mussels (Dreissena sp.) in freshwater ecosystems is a persistent problem which calls for antifouling treatments being fully efficient, long-lasting, and environmentally safe. The present study assessed the potential toxicological impact and the effectiveness of an elastomer-based coating containing salts that would make surfaces repulsive to zebra mussel attachment. Laboratory testing using standard analytical methods for water and wastewater, and a battery of six bioassays confirmed that the leachates from the coating exhibited no toxic response suggesting its safety to the receiving environment. In situ experiments using multi-plate collectors indicated that biofouling by zebra mussels and sponges on coated surfaces was effectively reduced by up to 97% over one growing season. Effectiveness of the coating was slightly less (82%) during the second growing season. Results suggested that the repulsive effect would be due to the presence of salts within the elastomer-based coating affecting both zebra mussels and other freshwater organisms. Saltwater experiments indicated that the coating was totally ineffective to prevent biofouling in marine environments. In addition of being environmentally safe to use, results suggested that the coating can be an effective antifouling product for submerged structures in freshwater environments.

Recruitment and distribution ofDreissena polymorpha (Bivalvia) on substrates of different shape and orientation

Dreissena polymorpha recruitment on artificial substrates was studied in the Włocławek Dam Reservoir (the Vistula River, Poland). Densities on downstream and upstream vertical surfaces of plastic plates differed significantly from each other, with the former settled by more individuals. Vertical and horizontal plates, as well as upper and lower horizontal surfaces were settled similarly. In another experiment mussels settled on flat, convex and concave glass surfaces, directed upstream or downstream. Among the upstream surfaces, the concave ones were the most densely settled. No significant differences in mussel recruitment on various downstream surfaces were found. Thus, substrate shape influenced mussels only when they were exposed to water flow. Mussels were aggregated (Lloyd index > 1) along all the edges of the horizontal plates and along the upper edge of the vertical ones. Such distribution was probably caused by the post-settlement movement of metamorphosed individuals.

Though a great deal of research focuses on the range expansion and presence of adult zebra mussels, there is still a need to understand the processes of larval settlement and how that relates to adult populations. There is evidence that marine bivalves preferentially settle on filamentous substrates such as hydroid colonies and algae; however, similar studies are rare in freshwater systems. We examined the importance of filamentous substrate for the settlement of the zebra mussel (Dreissena polymorpha) larvae by deploying PVC settlement plates with and without polypropylene filaments in the Bark River for a 6-week period. Larval supply was monitored weekly. Our results suggest that artificial filaments facilitated recruitment, primarily by increasing surface area available for attachment. Mussels on artificial filaments were significantly smaller in size than mussels attached to filamentous or control plate surfaces, providing some evidence that mussels may detach from filamentous substrate after initial settlement. This study adds to our general understanding about the role of filamentous substrates in the process of larval settlement and suggests that substrates colonized by filamentous epibionts may face increased risk of fouling by zebra mussels.
