Sea lice are parasitic marine copepod crustaceans that externally attach to fish hosts. In Canada, the three main sea lice species of concern are Caligus elongatus on the Atlantic coast, Caligus clemensi on the Pacific coast, and Lepeophtheirus salmonis on both the Atlantic and Pacific coasts due to their parasitism of farmed anadromous salmonids.
The Province of Nova Scotia and the Municipality of the District of Argyle have signed a Memorandum of Understanding (MOU) to explore the potential of an Aquaculture Development Area (ADA) for shellfish and marine plant aquaculture. ADAs identify areas for potential marine aquaculture development through a science-based collaborative review process. Ecological, economic, and social
CMAR collects data on critical environmental variables to support and inform science-based development of coastal industry, guide government policy and management decisions, encourage environmental stewardship, and ensure preparedness for climate change impacts. Since 2017, CMAR has conducted high-resolution monitoring of Nova Scotia's coastal waters. This monitoring primarily includes temperature, dissolved oxygen, and intermittent salinity
CMAR works with the Nova Scotia Department of Fisheries and Aquaculture (NSDFA) and marine service providers to deploy Acoustic Doppler Current Profilers (ADCP) to measure current speed and direction at coastal locations throughout Nova Scotia. Deployment locations and downloadable reports can be accessed below in the ADCP map.
The Canadian Shellfish Sanitation Program (CSSP) tests water samples for the presence of bacteria to ensure shellfish are safe for human consumption. Current water sampling methods are logistically challenging, expensive, and typically require repeated vessel-based sampling. The Centre for Marine Applied Research and Spiri Robotics are developing an aerial drone as an innovative approach
CMAR commissioned an economic impact assessment of the aquaculture industry in Nova Scotia. The report describes the benefits of the aquaculture industry on the Nova Scotia economy, its potential for future expansion, and some of the challenges the industry might face. You can view the executive summary here. The full report contains confidential business
CMAR is developing exposure models to assist aquaculture operators in choosing infrastructure to withstand extreme weather events and to select sites less likely to be affected by a high wave and current action. CMAR captures a range of wave and current data from around the province to validate exposure models with funding from the
CMAR is part of Canada’s Ocean Supercluster’s project to centralize oceanographic, biological and socioeconomic data into the Canadian Integrated Ocean Observing System (CIOOS). Through collaboration between the aquaculture and renewable energy sectors, oceanographic sensors will be deployed and maintained, data will be collected, verified and integrated into a centralized database, and tools will be
Eelgrass is the primary seagrass species in Atlantic Canada. It is an ‘Ecologically Significant Species’ and protected under federal legislation through a prohibition on the harmful alteration, disruption, or destruction of fish habitat. The Centre for Marine Applied Research (CMAR) has produced a comprehensive report on the potential for interaction of shellfish and finfish
Understanding nearshore ice dynamics is critical to mitigating risk and optimizing the placement of aquaculture infrastructure. CMAR and Nova Scotia Community College’s Applied Geomatics Research Group (NSCC-AGRG) assessed methodologies of traditional ice charts in combination with aerial imagery from Unmanned Aerial Vehicles (UAV), helicopters and remote sensing, to recommend best practices for mapping and
Nova Scotia hosts a growing number of finfish and shellfish aquaculture facilities located in coastal waters and on land. There is interest in further development. A challenge for prospective growers is that information on the province's infrastructure and service support is not readily accessible. While most of the required information exists in various forms
Developing aquaculture facilities further offshore, in the open ocean, has the potential to significantly increase production while avoiding some of the environmental issues and conflicts currently being faced by the coastal aquaculture industry. Due to its size and proximity to key markets, there is strong potential to develop offshore aquaculture in Canadian waters, particularly off
