Image of Kidneyshell
The Kidneyshell is a medium to large freshwater mussel with a shell that is kidney-shaped, thick, solid, and smooth. It is easily recognized by its elongate, yellow-brown shell with wide, interrupted green rays that look like squarish spots. The Kidneyshell reaches a maximum length of 120 mm in Canada.
Distribution and Population
The Kidneyshell is found in the Great Lakes drainage basin in the United States. Its distribution in Canada is now limited to Lake St. and the Sydenham and Ausable rivers in southern Ontario.
The Kidneyshell was always rare in Lake Erie, Lake St. Clair and the Niagara and Detroit rivers, but has now been virtually extirpated from these waters by the Zebra Mussel Dreissena polymorpha. Only seven live animals were found during extensive surveys in Lake St. Clair between 1999 and 2001. The Kidneyshell is also apparently extirpated from the Thames and Grand rivers. It is now restricted to two reproducing populations that occupy a 100-km reach of the East Sydenham and a 25-km reach of the Ausable River. There is also evidence that it may be declining in abundance in the Sydenham River.
The Kidneyshell is most often found in small to medium-sized rivers and streams, where it prefers shallow areas with clear, swift-flowing water and substrates of firmly packed coarse gravel and sand. It is rarely found in either large rivers or headwater creeks, but has been found on gravel shoals in Lake Erie and Lake St. Clair. It is often found near beds of Water Willow, an aquatic plant. It is usually found deeply buried in the substrate.
The Kidneyshell has separate sexes but males and females look alike. The lifespan is not known, but is probably at least 10 years. Kidneyshells, like all freshwater mussels, feed on bacteria and algae that they filter from the water with their gills.
Like other freshwater mussels, the Kidneyshell is parasitic on fish during its larval stage. The female mussel attracts nearby fish by releasing her larvae into the water in packets that look like fish prey items. When the fish bites into these packets, the mussel larvae are released and attach to the fish’s gills, where each forms a cyst. After a period of time, the larvae transform into juveniles, which then drop off and fall to the substrate to begin life as a free-living mussel. Different mussel species have different host fishes. The most likely hosts for the Kidneyshell in Ontario are Greenside Darter Etheostoma blennoides, Fantail Darter E. flabellare, and/or Johnny Darter E. nigrum.
Zebra Mussels have nearly destroyed native freshwater mussel communities in the Great Lakes. Approximately 60% of sites where the Kidneyshell was found historically are now infested with Zebra Mussels. Populations in the Grand and Thames rivers were likely extirpated due to the combined effects of sewage pollution and agricultural impacts. The two remaining populations in Canada, located in the East Sydenham and Ausable rivers, are threatened by factors related to intensive agriculture, especially heavy loadings of silt and nutrients. Muskrats are also a potential limiting factor, since the Kidneyshell is one of the mussel species on which they prey.
The Kidneyshell is protected under the federal Species at Risk Act (SARA).
More information about SARA, including how it protects individual species, is available in the Species at Risk Act: A Guide.

Reports on the Progress of Recovery Document Implementation
As a result of the overlap in the historic and current ranges of the Round Hickorynut and Kidneyshell, there is substantial commonality in threats to their continued survival. A key component in the progress towards fulfilling recovery objectives has been the systematic collaboration with existing ecosystem recovery teams. This collaboration has taken the form of multiple research projects as well as stewardship teams that actively monitor and coordinate habitat improvement projects on the Ausable, Sydenham, and Thames rivers systems. These collaborative efforts resulted in concrete progress in the form of habitat improvement and protection, and important biological insights of these two species.
COSEWIC Status Reports
The Kidneyshell, Ptychobranchus fasciolaris (Rafinesque 1820), is a medium to large freshwater mussel (maximum length in Canada ~120 millimeters) that is easily recognized by its elongate, yellow-brown shell with wide, interrupted green rays that look like squarish spots.
By 2001, this species had been lost from about 70% of its historical range in Canada due to the impacts of the Zebra Mussel and habitat loss from land use practices. It is now restricted to the East Sydenham and Ausable rivers, Lake St. Clair delta, and Medway Creek of the Thames River. The population in Lake St. Clair is close to extirpation. Both Ausable and East Sydenham river populations appear to be reproducing, but populations in Medway Creek and Lake St. Clair are not reproducing. Populations are threatened by pollution from agriculture, urban and road runoff sources, and invasive species (dreissenids and Round Goby).
A response statement is a communications document that identifies how the Minister of the Environment intends to respond to the assessment of a wildlife species by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). The document provides a start to the listing and recovery process for those species identified as being at risk, and provides timelines for action to the extent possible.
The Ontario Freshwater Mussel Recovery Team (OFMRT) was formed in the spring of 2003 to address concerns about the status of Ontario's freshwater mussel populations and to begin to address the recovery planning obligations under Canada's new Species at Risk Act (SARA). The National Recovery Strategy for the Round Hickorynut and the Kidneyshell was developed by the OFMRT using the best available information in an effort to reduce the threats, prevent their extirpation and, if possible, to restore these species to healthy, self-sustaining levels. In recognition of the degree of overlap between these species in both their historical and current distributions, as well as the commonality of threats, the OFMRT has adopted a multi-species approach to the recovery of these species.
The Ausable River, located on the northern edge of the Carolinian Zone in southwestern Ontario, supports one of the most diverse and unique assemblages of aquatic fauna for a watershed of its size in Canada. At least 26 species of freshwater mussels and 85 species of fish have been found here. Many of these species are rare and 12 species, including six mussels and six fishes, have been assessed by the Committee on the Status of Endangered Wildlife in Canada as Endangered, Threatened or Special Concern. The majority of these species are protected under the federal Species at Risk Act (SARA) and/or the Ontario Endangered Species Act, 2007 (ESA). Five freshwater mussels (Kidneyshell, Northern Riffleshell, Snuffbox, Mapleleaf and Rainbow) and three fishes (Eastern Sand Darter, Lake Chubsucker and Pugnose Shiner) are the focus of this Action Plan. The needs of these at risk fishes and mussels within the Ausable River watershed will be addressed using a multi-species, ecosystem-based approach. The present plan is guided by seven SARA recovery strategies for these eight species and builds on the draft ecosystem-based Ausable River Recovery Strategy that was developed (Shawn Staton, ARRT, unpublished, 2005).
The Sydenham River in southwestern Ontario supports an amazing diversity of aquatic life. Located in the lower Great Lakes basin, the river contains the greatest diversity of freshwater mussel species of any watershed in Canada. At least 34 species of mussels and 80 species of fishes have been found here. Many of these species are rare and seventeen species, including eleven mussels and six fishes, have been assessed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as Endangered, Threatened or Special Concern. The majority of these species are protected under the federal Species at Risk Act (SARA) and seven freshwater mussels (Round Hickorynut, Kidneyshell, Northern Riffleshell, Snuffbox, Round Pigtoe, Rayed Bean and Salamander Mussel) and two fishes (Eastern Sand Darter – Ontario population and Northern Madtom) are the focus of this action plan. The needs of these at risk fishes and mussels within the Sydenham River watershed will be addressed using a multi-species, ecosystem-based approach. The present plan is guided by four SARA recovery strategies for these nine species and builds on the ecosystem-based Sydenham River Recovery Strategy completed in 2003.
This Order acknowledges receipt by the Governor in Council of the assessments of the status of wildlife species done pursuant to subsection 23(1) of the Species at Risk Act (SARA) by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). The purpose of SARA is to prevent wildlife species from being extirpated or becoming extinct, to provide for the recovery of wildlife species that are extirpated, endangered or threatened as a result of human activity and to manage species of special concern to prevent them from becoming endangered or threatened.
Schedule 1, the List of Wildlife Species at Risk of the Species at Risk Act (SARA), is amended by Order of the Governor in Council (GIC), on the recommendation of the Minister of the Environment, by the addition of 73 species. This Order is based on scientific assessments by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) and follows consultations with provincial and territorial governments, Aboriginal peoples, stakeholders and the public, and analysis of costs and benefits to Canadians.
COSEWIC Annual Reports
Under Canada’s Species at Risk Act (SARA), the foremost function of COSEWIC is to “assess the status of each wildlife species considered by COSEWIC to be at risk and, as part of the assessment, identify existing and potential threats to the species”.
COSEWIC held two Wildlife Species Assessment Meetings in this reporting year (October, 2012 to September 2013) from November 25 to November 30, 2012 and from April 28 to May 3, 2013. During the current reporting period, COSEWIC assessed the status or reviewed the classification of 73 wildlife species.
The wildlife species assessment results for the 2012-2013 reporting period include the following:
Special Concern: 19
Data Deficient: 4
Not at Risk: 1
Of the 73 wildlife species examined, COSEWIC reviewed the classification of 50 species that had been previously assessed. The review of classification for 26 of those species resulted in a confirmation of the same status as the previous assessment.

The objective is to sample Round Goby for both behavioural and genomic assays. The source site will be St. Claire River near Sarnia, where the Round Goby was initially found and assumed to be the first longest established site. The established sites will be the river mouths and the invasion fronts will be determined by methods from Bronnenhuber et al. (2011).
The purpose of the project is to determine the sensitivity of the early life stages (glochidia) of endangered species of freshwater mussels to salt (NaCl and road salt).
The Medway Sanitary Trunk Sewer project involves the installation of a sanitary trunk along the Medway Valley to service the communities in north London. Phase 2B of the Medway Sanitary Trunk Sewer is the final extension of the Medway trunk sewer. Phase 2A was constructed in 2007 and involved two crossings and associated mussel relocation and monitoring. The current phase, 2B, involves three crossings on Medway Creek and associated mussel relocation and monitoring. The total estimated prescribed search area for all three crossings is 1828 m2.
In addition to the three crossing sites, two other areas need to be searched for mussels, including the relocation area and a control area. The presence of mussels in these areas will be documented to assess the potential impact, if any, of relocated mussels on the population of mussels already living in the relocation sites. Growth and survival of relocated mussels will be monitored and compared to mussels endemic to the relocation site (i.e., control mussels) at one month, one year and two years post re-location.
The St. Clair Region Conservation Authority (SCRCA) is sampling fish and mussels in several locations for presence/absence data. Currently, fish and mussel data is lacking in these areas. Baseline data will be collected to assist in future project proposals and inquiries. Benthic sampling will be undertaken for watershed characterization to allow the SCRCA to assess water quality throughout the watershed. Data obtained will assist the SCRCA in the identification of potential rehabilitation sites and impact monitoring.
The objective of the project is to apply selective lampricide to assess and control Sea Lamprey populations in the Great Lakes. Assessment surveys are routinely conducted in tributaries and lentic areas to determine the presence, distribution, and abundance of Sea Lamprey larvae. In deep water (>0.8 m) areas, surveys are conducted with the application of granular Bayluscide, a bottom-release formulation of lampricide, within the demarcated boundaries of the plots with a standard area of 500 m2. Tributaries harbouring larval Sea Lamprey are treated periodically with lampricides to eliminate or reduce larval populations before they recruit to the lake as feeding juveniles. The treatment units administer and analyze TFM, or TFM/Niclosamide mixtures (TFM augmented with Bayluscide 70% wettable powder or 20% emulsifiable concentrate) during stream treatments, and apply 3.2% granular Bayluscide (gB) to control populations inhabiting lentic areas.
The objective of the project is to conduct freshwater mussel surveys and monitoring in Central and Arctic Region. 1) Quantitative sampling - historical monitoring stations on the Thames and Maitland rivers will be revisited and sampling completed during the initial round of monitoring (2005) will be repeated; 2) Semi-quantitative sampling - sampling at Little Bear Creek and Walpole Island will be undertaken using habitat appropriate methods (wading, visual/tactile, searches, calm rakes, etc.); 3) Identification workshop - the workshop will take place in late June over a two-day period. The first day is a laboratory component working with preserved specimens. The second day is spent on-site at a location in the Sydenham River where attendees will develop and practise field identification skills under the guidance of experienced malacologists; 4) Genetic sampling - depending on which species are detected during sampling, it may be necessary to collect genetic samples for further analyses; 5) Depending on which species are found during sampling, it may be necessary to subsample to evaluate the reproductive state of individuals; and, 6) Tagging - when necessary some individuals may be tagged for future identification, using non-invasive tagging techniques.
The activities authorized by this permit that may cause incidental harm to Kidneyshell (Ptychobranchus fasciolaris), Round Hickorynut (Obovaria subrotunda), and Round Pigtoe (Pleurobema sintoxia) consist of the capture and relocation of species at risk mussels within the prescribed search area of approximately 2,295 m2, which includes the overall cofferdam footprint of 1,442 m2 and a buffer, in the Welland River, during isolation of in-water work areas, cofferdam installation, and dewatering activities. The effects that the activity may cause to the listed species, their critical habitat, and the effects of those changes authorized by the permit include the incidental harm, harassment, or death of Kidneyshell, Round Hickorynut, and Round Pigtoe resulting from their capture, processing, and relocation.
Phragmites australis is an invasive species that is expanding exponentially in Long Point Bay and Rondeau Bay, displacing native species and limiting critical habitat for numerous species at risk. A method that has been used in the United States but is relatively new to Canada includes applying a custom made herbicide, RoundUp (active ingredient glyphosate), with AquaSurf (a surfactant), which has been shown to be effective at reducing Phragmites density and spread.
This project is an extension of the works that the Ontario Ministry of Natural Resources and Forestry (OMNRF) conducted in 2016, 2017 and 2018 in Long Point Bay and Rondeau Bay as part of a 5-year pilot project to determine the effectiveness of this method in Canada. The current proposal is to treat a total of 48 hectares in the following locations in Rondeau Bay and Long Point Bay by ground application: Rondeau Provincial Park (10 ha), Long Point Bay (5 ha), Turkey Point Region (1 ha), Lower Big Creek Marshes (6 ha), Big Creek Watershed (20 ha), North Shore of the Inner Bay (6 ha), and as required where regrowth is observed in Long Point Bay. This activity may result in the incidental harm, harassment, or death of Eastern Pondmussel (Ligumia nasuta), Round Pigtoe (Pleurobema sintoxia), Lake Chubsucker (Erimyzon sucetta), Pugnose Shiner (Notropis anogenus), Kidneyshell (Ptychobranchus fasciolaris), Rainbow (Villosa iris), Round Hickorynut (Obovaria subrotunda), Mapleleaf (Great Lakes - Upper St. Lawrence River populations) (Quadrula quadrula), Spotted Gar (Lepisosteus oculatus), or Eastern Sand Darter (Ammocrypta pellucida) (Ontario populations) resulting from the application of herbicide, use of heavy equipment for spraying by ground, or oxygen depletion from vegetative die-off.
The objectives of the activities covered by this permit are: 1) To conduct quantitative and semi-quantitative surveys for species at risk mussels at sites at locations across southern Ontario to track changes in species and habitat over time, and evaluate recovery efforts; 2) To hold a mussel identification workshop in late June over a two-day period. The second day will be spent at a site on the Sydenham River where attendees will practice field identification skills under guidance of experienced malacologists; 3) Depending on species detected during qualitative and semi-quantitative sampling, to obtain genetic samples for further analyses, and to evaluate reproductive condition of animals found; 4) To conduct a morphometric analyses on animals collected during quantitative and/or semi-quantitative sampling; and, 5) To tag some individuals when necessary for future identification.
These activities will involve the capture of all mussel species listed on the permit, via quadrat sampling or timed searches, from sites listed on the permit. For quantitative sampling, substrates in 1 m x 1 m quadrats will be excavated by hand. For all sampling, any mussels found will be identified and processed (count, measure, morphometric analyses, tagging, obtaining genetic samples, etc.). All mussels will be returned alive to the locations they were found after processing.
The objectives of the activities covered by this permit application are to conduct fish and mussel surveys in the Thames River watershed. Collected baseline data will be used to assist in future project proposals and inquiries.
The activities authorized by this permit consist of the capture of any of the species listed on this permit from the Thames River watershed, and the handling of any of the species listed on this permit for the purposes of identification and processing (count, measure, photograph, etc.). Fishes will be released alive with the exception of some smaller fishes that may be retained to confirm identification. All mussels will be returned alive to the locations they were found. Fish sampling will be completed through the use of a backpack electrofishing unit. Mussel surveys will adhere to Mackie et al. (2008).
The objectives of the activities covered by this permit are to conduct fish and mussel surveys in the St. Clair River watershed and the Lake St. Clair watershed. Collected baseline data will be used to assist in future project proposals and inquiries.
The activities authorized by this permit consist of the capture of any of the species listed on this permit from the St. Clair River watershed and the Lake St. Clair watershed, which will require the handling of any of the species listed on this permit for the purposes of identification and processing (count, photograph, etc.). Fishes will be released alive with the exception of some smaller fishes that may be retained to confirm identification. All mussels will be returned alive to the locations they were found. Sampling will be completed through the use of a backpack electrofishing unit, seine net, or minnow traps where necessary, using the Ontario Stream Assessment Protocol (OSAP). Mussel surveys will adhere to Mackie et al. (2008).
The objectives of the activities covered by the permit are to conduct a survey (seining and trawling) of the East Sydenham River to determine if Northern Madtom (Noturus stigmosus) still exists in this watershed. Previous recent surveys have been unsuccessful in detecting this species. The last known record of Northern Madtom in the East Sydenham River was from 1929 near Alvinston, Ontario, and from 1975 near Florence, Ontario. The other species listed on the permit may be captured incidentally during the surveys.
The activities authorized by the permit consist of the capture of Northern Madtom from the East Sydenham River using a small mesh trawl and/or a small mesh seine net. The gear type used will depend on habitat conditions and water levels at each site. Identification and processing will involve the handling of Northern Madtom (count, measure, photograph etc.). After fishes are processed (identified, measured) they will be released back to the river, alive. Vouchers will be collected using digital cameras, but some vouchers of smaller fishes may be retained in 10% formalin to confirm identification, if digital vouchers cannot be collected. These survey activities may result in the incidental capture and handling of Eastern Sand Darter (Ammocrypta pellucida) and the species at risk mussels listed on the permit, for the purposes of identification and processing (count, measure, photograph etc.). Any species at risk incidentally captured will be returned alive to the location of capture.
The objectives of the activities covered by the permit are: 1) to study post-excystment juvenile unionid mussel dispersion; 2) to study the effects of multiple stressors on unionid mussel suspension feeding; 3) to study the effect of shear stress on juvenile unionid settlement; 4) to study the association between flow velocity and shell orientations and morphometrics; and, 5) to study the physical conditions present in mussel beds. The species listed on the permit may be captured incidentally during this work.
The activities authorized by the permit consist of the incidental capture of species listed on the permit from the Ausable, Grand, Sydenham, and Thames rivers. For the juvenile studies, excavations along a transect across the river will be undertaken using an airlift system that will vacuum up the fine sediments and any juvenile mussels in a 12 x 12 cm quadrat. The excavated material will be carefully processed through a series of sieves to define size classes of sediment. For feeding studies, species will be collected via three possible methods: "raccooning" and excavation; manual sieving through the sediment; and, visual searching (depending on water clarity).
These activities will involve the handling of the species listed on the permit for the purposes of identification and processing (count, measure, marking, photograph etc.). Any juveniles found will be measured, photographed, and, along with the sediment, returned to their original place along the transect. All mussel species at risk, once identified, will be measured, marked and returned to the spot where they were collected. The marking is completed with a metal probe that is used to etch the periostracum of the shell (with a unique number), which does not harm the mussel.
The objective of the activities covered by the permit is to sample municipal drains for the purpose of classifying unrated drains following the Classifying Ontario Municipal Drains Protocol (Fisheries and Oceans Canada). As fisheries assessments have not been previously conducted on many unrated municipal drains, the species listed on the permit may inhabit these drains and may be captured incidentally during the course of the work.
The activities authorized by the permit include: 1. The incidental capture of species at risk (SAR) from the locations listed on the permit using seine nets and/or backpack electrofishing units. Within each sample site, approximately 40 m or 10x the wetted width of the watercourse will be sampled for fishes using either a backpack electrofisher, or a seine net depending on habitat suitability. Within the sample site, block nets will be set up and a minimum of three passes will be completed; 2. The handling of the listed SAR for the purposes of identification (count, measure, photograph, etc.). With the exception of vouchers that may be retained to confirm identification, all fishes will be released alive after processing. Vouchers will be collected using digital cameras for larger fishes and all mussels; however, some vouchers of smaller fishes may be retained in 10% formalin or 95% ethanol to confirm identification (if digital vouchers cannot be collected); and, 3. The possession and transport of any of the listed species that are killed incidentally or for vouchering purposes, preserved in 10% formalin or 95% ethanol.
The objective of the activities covered by the permit are to conduct habitat assessments and survey for species at risk mussels in areas where in-water works are proposed at various locations across Ontario. The species listed on the permit may be captured incidentally during the course of this work.
The activities authorized by the permit include: 1. The capture of the species listed on the permit via visual search using viewing boxes and raccooning, from various waterbodies throughout Ontario; 2. The handling of the species listed on the permit for the purposes of identification and photographing; and, 3. The possession and transport of dead specimens/shells/valves of any of the species listed on the permit found during the course of the sampling.
The objective of the activities covered by the permit are to conduct species at risk mussel surveys and habitat assessments at established long-term index stations in the Ausable River watershed to track changes in species and habitat over time, and evaluate recovery efforts. The species listed on the permit may be captured during the course of the work.
The activities authorized by the permit consist of: 1. The capture of all mussel species listed on the permit, via quadrat sampling, from index stations on the Ausable River. Substrates in 1 m x 1 m quadrats will be excavated by hand; 2. The handling of the species listed on this permit for the purposes of identification (count, measure, photograph, etc.). All mussels will be released alive after processing to the locations they were found; and, 3. The possession and transport of dead specimens/shells/valves of any of the species listed on this permit killed incidentally or found during the course of the sampling.
Under the guidance of Fisheries and Oceans Canada (DFO), the activity involves: 1) establishing a network of permanent monitoring stations throughout historical and present ranges of the Sydenham River, to permit tracking of fish populations, analysis of trends and patterns, and permit the evaluation of recovery actions; 2) establishing and implementing a habitat monitoring program that includes water quality and substrate components. The monitoring program will provide insight into the significance of threat factors. Targeted species at risk fish sampling will be conducted in historically occupied habitat (river reaches in the vicinity of Florence and Alvinston), as well as other potentially suitable habitats, using sampling techniques proven to detect species at risk fishes; and, 3) starting in 2020 and following the guidance of DFO, conduct a spatial pattern study of mussel distribution by completing a systematic survey in a specific reach (or reaches) in order to better understand population abundance/density and species-to-habitat relationships in the Sydenham
The St. Clair Region Conservation Authority (SCRCA) will collect fishes using a backpack electrofishing unit, seine net, or minnow traps where necessary, using the Ontario Stream Assessment Protocol. Mussel surveys will adhere to protocol found in Mackie et al. (2008). Fifteen sites will be monitored according to the Ontario Benthos Biomonitoring Network Protocol. At each site, this protocol involves using the travelling kick and sweep method for three minutes, covering an area of about 10 m2 at three transects (optimally riffle-pool-riffle) within a stream meander wavelength. The sites are selected to represent the main watercourse. Each of the small watercourses has at least one sampling site.
