To mitigate the impact of instream construction on fish populations, Fisheries and Oceans Canada (DFO) requires that fish stranded within areas destined to be dewatered be captured and released into nearby habitat that will remain wetted. NSC has considerable experience in planning and conducting fish salvages to meet requirements of the Fisheries Act
. The company has conducted salvage fisheries that last only a few hours and others that span months, in both remote northern and urban environments. Company personnel are trained in confined spaces protocols and removal of fish from turbine draft tubes. NSC has also applied for permits under the Species at Risk Act
to conduct mussel salvages at construction sites that potentially contain the Endangered Mapleleaf Mussel. Depending on the needs of the project, mussels are collected by either raking or by hand by divers. Mussels are relocated upstream according to DFO protocols.
