5203 |a“Fish habitat compensation to offset the loss of productive fish habitat (fish and/or shellfish) in the Northwest Atlantic, especially in the offshore marine environment, is challenging. Between 2001 and 2005 works or undertakings associated with two offshore oil projects included activities that, as a condition of regulatory approval, required the creation of scallop shell reefs and a rock reef. Monitoring for the reef compensation projects included metrics used to demonstrate the effectiveness of the compensation including those to determine whether there were any changes in structural integrity and stability and species utilization of the reefs. Methods used to determine structural integrity, substrate stability and fish utilization using SCUBA divers included visual and video surveys to determine shell movement, settling/sinking of materials, changes or impairments to new materials, utilization of reefs by species. As well, for the rock reef, control sites were established along the shoreline and adjacent seabed as a comparison to the observed conditions on the artificial rock reef"--Abstract, p. iv.
