Freshwater mussels contribute important ecological functions to aquatic systems. The water filtered by mussel assemblages can improve water quality, and the mixing of sediments by burrowing mussels can improve oxygen content and release nutrients. However, nearly 70 percent of North American freshwater mussel species are listed as either endangered, threatened, or in decline. In Ontario, 28 species are in decline or in need of protection.

Fish Status and Ecosystem Health - Caged Invertebrates

In situ exposures of Hyalella azteca in Athabasca River tributaries - Summary of activities (2010, 2012, 2013, 2014)

In situ exposures with Hyalella azteca were conducted within the oil sands region to assess differences in survival and growth of invertebrates caged at natural sites (i.e., exposed to naturally occurring sources of bitumen) compared to sites influenced by oil sands mining activity (i.e., exposed to both naturally occurring and anthropogenic sources of bitumen).Hyalella were collected from a wetland within the Athabasca River watershed but outside the area of oil sands development and activity. They were then placed in cages submerged at 3 sites on the Ells River, 3 sites on the Firebag River, and 4 sites on the Steepbank River. Five cages were deployed per site, each cage containing 20 Hyalella. Cages were removed two weeks after deployment, and Hyalella were counted and weighed as a group to determine growth.

Data are contaminants in tissue of caged mussels put in the river for 3 weeks at about 25 stations located on the Canadian and US side of the river. The main objective of the study is to identify contaminant sources, or source areas requiring more detailed follow-up investigations, based on the level  of contaminants in the mussels. Compounds monitored include: * organochlorinated pesticides * Polychlorinated biphenyls * dioxins/furan * chlorinated benzenes * Polycyclic aromatic hydrocarbons * industrial organic compounds

The toxicity and bioconcentration of 3 pharmaceuticals (amitriptyline, iopamidol, and sertraline) were examined using multiple life stages (larval, juvenile, and adult) of the unionid mussel Lampsilis siliquoidea. The endpoints examined varied with life stage but included survival, behavior (algal clearance rate, filtering frequency), and oxidative stress. Glochidia and juveniles were more sensitive than adult mussels. However, the compounds examined were not toxic at concentrations detected in the environment.

This GIS dataset is a GIS version of AGS Map 150, Sheets 1 - 6, as mapped at 1:250,000-scale by Bayrock and Reimchen. Digitizing was originally done by Prairie Farm Rehabilitation Administration (PFRA). The data were supplied to AGS by PFRA in individual map sheets, in Arc/Info coverage format. Data were subsequently checked and edge-matched to create a single polygon coverage.
