The development of video monitoring methods and management thresholds to characterize the fish farm impacts on hard-bottom substrates

Description

Previous work has recommended benthic monitoring tools and management thresholds to minimize benthic impacts originating from fish farms. Although these tools were cost-effective, practical, accepted by the scientific community, and readily available in Canada, they were largely applicable to soft-sediment substrates. This project identifies and tests benthic sampling methods to monitor, quantify, and evaluate potential impacts to hard-bottom substrates in British Columbia and Newfoundland. A classification system will be developed to identify the effects of farm waste deposition on hard-bottom substrates. Another goal is to update a sampling decision tree to provide a comprehensive framework integrating both hard- and mixed-bottom monitoring techniques. This will avoid duplication of effort and decrease costs to industry and regulatory agencies when conducting environmental assessments.
