Monitoring to determine the efficacy of utilizing fishless lakes as fish habitat compensation in Labrador / M.M. Roberge and T.N. Warren.: Fs70-5/2017-042E-PDF

“This paper reports on methods for assessing the effectiveness of fish habitat-related measures implemented as part of the regulatory approval for two mining projects in Newfoundland and Labrador. Between 2003 and 2004 works or undertakings associated with two mining projects (one in western Labrador and another in northern Labrador) included activities that, as a condition of regulatory approval, required compensation works to offset the loss of lacustrine habitats though the transfer of fish from the impacted lakes into fishless lakes located within their respective watersheds. After the fish transfers, monitoring programs were required to determine whether there was sustainability of the transferred fish populations. Methods used to determine population sustainability included such things as visual surveys along the shoreline, outlets and into tributaries; electrofishing to determine recruitment success; mark-recapture studies to estimate population size; and collection of various morphometrics to evaluate fish population status/health. At one location an outlet stream was also created to provide for spawning and rearing habitats. Monitoring to determine effectiveness of the created outlet included surveys to assess habitat features, including wetted width, depth, shape, bank height, water discharge/velocity (high, medium, low flows) and habitat utilization (visual and electrofishing surveys)"--Abstract, p. iv.
