Atlantic Sturgeon Habitat Areas in the St. Lawrence River and Estuary

Geospatial data details Atlantic sturgeon breeding, feeding, and concentration areas in the St. Lawrence River and Estuary. The information was compiled from a literature review of documents published between 1993 and 2003. The dataset is provided by Fisheries and Oceans Canada.

Use Cases

• Map breeding, feeding, and concentration areas to support habitat conservation planning for Atlantic sturgeon.
• Analyze spatial overlap between different habitat types (breeding vs. feeding) to inform ecosystem management.
• Integrate habitat area polygons with other geospatial layers for environmental impact assessments in the St. Lawrence region.

Strengths

• Data is derived from a defined literature review covering scientific and governmental documents from 1993 to 2003.
• Provides specific habitat classifications for breeding, feeding, and concentration areas of a species of concern.
• Published by the authoritative government agency Fisheries and Oceans Canada.

Limitations

• The underlying literature review is over 20 years old, so habitat conditions may have changed.
• The dataset's spatial accuracy and completeness are dependent on the source documents reviewed.
• No sample data or column schema is provided, limiting immediate understanding of data structure.
