Infographic: Rise and Fall of Fish and Invertebrates

Fish and invertebrate communities have changed dramatically in Atlantic Canada due to overfishing and climate change.

Trends: Post-Cod collapse (1992)

Decreasing species

  • Atlantic cod. Bioregions: Gulf of St. Lawrence, Scotian Shelf, Newfoundland and Labrador Shelves.
  • Capelin. Bioregions: Newfoundland and Labrador Shelves.
  • Atlantic herring. Bioregions: Scotian Shelf.
  • Atlantic mackerel. Bioregions: Gulf of St. Lawrence.

Increasing species

  • Snow crab and Northern shrimp. Bioregions: Gulf of St. Lawrence, Scotian Shelf, Newfoundland and Labrador Shelves.
  • Greenland halibut. Bioregions: Gulf of St. Lawrence.
  • Atlantic herring. Bioregions: Gulf of St. Lawrence.
