Pelagic fish live in midwater or close to the surface, in contrast to groundfish, which live in deeper waters. Crustaceans are shelled animals with joints, such as lobster, crab and shrimp. Molluscs are the species we commonly think of as shellfish, including bivalve species like clams, oysters and mussels. Serious harm likely indicates that best available information shows that the stock is in the Critical Zone, or the stock health is likely to decline if the current harvesting rates continue. Serious harm possible indicates that best available information shows that the stock is in the Cautious Zone, or the stock health may potentially decline if current harvesting rates continue. Serious harm unlikely indicates that best available information shows that the stock is in the Healthy Zone, or it is unlikely that the stock health will decline if current harvesting rates continue.",,,, Source: Fisheries and Oceans Canada (2025) Sustainability Survey for Fisheries (https://www.dfo-mpo.gc.ca/reports-rapports/regs/sff-cpd/survey-sondage/index-en.html).,,,, Available on the Environmental indicators website (www.canada.ca/environmental-indicators).,,,,
