Developing empirical metrics to define time of lobster mortality to support processing decisions

The American lobster (Homarus americanus) fishery is the most profitable commercial fishery in Atlantic Canada, valued at ~$1.5 billion in 2019. Due, in part, to the chaotic nature of the beginning of the lobster season, immobile lobster can arrive at lobster pounds. Under current Canadian Food Inspection Agency (CFIA) guidelines, these lobsters are considered unfit


A global review of sea lice regulations and monitoring efforts

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


Assessing climate change vulnerability of seafood industry-dependent communities in Nova Scotia

Climate change is increasing global ocean temperatures and causing reduction in pH and oxygen. Global sea level is also rising at an accelerating rate, increasing the risk of coastal erosion and flooding. Nova Scotia is highly dependent on coastal resources for employment and infrastructure,and climate change is a threat to coastal communities and industries.

Coastal Monitoring Program

CMAR collects data on critical 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 .

Since 2017, CMAR has conducted high-resolution monitoring of Nova Scotia’s coastal waters. This monitoring primarily includes temperature, dissolved oxygen, and intermittent salinity measurements, recorded by sensors


Current Profiles of Coastal Waters

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.


Supporting the Development of Offshore Aquaculture

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


Managing Aquaculture and Eelgrass Interactions in Nova Scotia

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 aquaculture


Resource Map for Aquaculture Users

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
