Municipal wastewaters are major sources of pollution for the aquatic biota. The purpose of this study was to determine the levels of some pharmaceutical products and the immunotoxic potential of a municipal wastewater aeration lagoon for the treatment of the domestic wastewaters of a small town with wastewater inputs from a 400-bed hospital complex. Endemic mussels were collected, caged and pla...

We compared density and morphology of wild mussels Mytilus trossulus growing naturally on shellfish farming structures to that of mussels from nearby intertidal areas, and considered the relevance to molluscivorous sea ducks. Mussel density on aquaculture structures greatly exceeded that of intertidal areas and farm mussels were larger, had lower shell mass, and had weaker byssal attachments. D...

The invasive golden mussel, Limnoperna fortunei (Dunker, 1857), was introduced into the La Plata River estuary and quickly expanded upstream to the North, into the Paraguay and Paraná rivers. An ecological niche modeling approach, based on limnological variables, was used to predict the expansion of the golden mussel in the Paraguay River and its tributaries. We used three approaches to predict...

Providing benthic substrate is the most common method used for oyster reef restoration. The physical relief from seabed, increased habitat complexity, and attachment surfaces have been shown to improve health, recruitment, survival. While addition of shell material an effective restoration, its usefulness in mussel restoration has understudied. This study tested effectiveness adding two differe...

Bivalves frequently withstand shell damage that must be quickly repaired to ensure survival. While the processes underlie larval development have been extensively studied within context of ocean acidification (OA), it remains unclear whether repair is impacted by elevated pCO2. To better understand stereotypical process, we monitored mussels (Mytilus edulis) with sublethal breached mantle cavit...

Mussel growers in Prince Edward Island (PEI), Canada, currently use high-pressure water spraying (~700 psi) to mortally injure or dislodge invasive tunicates from mussel product and gear. An added benefit of this process may be the stimulation of byssal thread production, leading to improved mussel attachment. This study measured byssal thread abundance and thickness in cultured blue mussel Myt...

Shell shape variation of the freshwater mussel Castalia ambigua in relation to environmental and genetic drivers remains unresolved South America. Along an increasing upstream downstream hydrological gradient Caeté River, eastern Amazon, Brazil, we evaluated two co-occurring morphotypes C. ambigua: first is elongated compressed; second rounded inflated. We performed multivariate analysis on lat...

Common name Zebra-Muschel (German), moule zebra (French), racicznica zmienna (English, Poland), zebra mussel (English), dreisena (Lithuanian, Lithuania), svitraina gliemene (Latvian, Latvia), vaeltajasimpukka (Finnish, Finland), Zebramuschel (German, Germany), wandering mussel (English), tavaline ehk muutlik r?ndkarp (Estonian, Estonia), Dreikantmuschel (German, Germany), vandremusling (Danish,...

We report the synthesis of hydroxyapatite (HAp)-based antibacterial biomaterials using a mussel shell as calcium source and by integration silver ions via wet precipitation method. The doping at 2 mol% can provide silver-doped carbonated HAp while 10 mol% offer HAp/silver oxide nanocomposite. synthesized Ag-integrated samples exhibit H (263–903Mpa) E (0.96–3.31GPa) almost similar to cancellous ...
