Scientific research for the conservation of the species
Qualitative freshwater mussel surveys to inform freshwater mussel census. Goal is to set up an up to date data bank of localities for every species of freshwater mussel in Canada. Basic biometric data is collected on the spot with minimal disturbance of the animals themselves or their habitat, and all captured animals are released where they were collected after being identified and measured.

Location of Activity (province, territory or ocean):
a) Alternatives: Common options for finding live mussels hidden in sediment by excavation of bottom substrates, such as Ponar/Heckman grabs, biological dredges, rakes or kick nets have been purposefully excluded in order to minimise habitat and residence disturbances as well as potential harm to individuals. In situ surveys without handling would have further reduced affecting the species; however, the quality of data (i.e., species identification) would have been considerably compromised. b) Measures to minimize impact: Processing and subsequent prompt release at site of capture have been specifically designed to minimize stress and risk of injury to animals that might be found. Special attention is given to avoid treading on live animals during surveys. Every step on the river bottom explored is made after visually making sure no mussel is stepped upon, and surveys are only done when water visibility is optimal enough to ensure this security. Bottom substrate will not be disturbed other than by the minimal impact of walking on it, as no excavation measures will be employed. No live animals will be removed permanently from their habitat. All data collection on live animals will be done on-the-spot at every survey site. Ambiguous identification will be done from photographs to limit handling time in the field. c) Effects on survival and recovery: No specimens will be sacrificed or removed from habitats surveyed and none of the threats identified in the recovery strategies (to either species, or to individuals or habitat) will be exacerbated. As such, none of the population and distribution objectives will be compromised. Moreover, data recovered from these surveys support the recovery and action planning identified in the federal recovery documents for these species.
