Great Lakes Fish Community and Habitat Survey Data

Data from DFO Science surveys on freshwater fish communities in the Great Lakes basin. It includes sampling site location, date, fish species and counts, and associated habitat information, compiled for species of conservation concern.

Use Cases

• Analyze fish species counts across sampling sites to identify biodiversity hotspots and areas of conservation concern.
• Model the relationship between habitat information and fish community composition to assess environmental drivers.
• Track changes in fish populations over time using date and location data to monitor long-term ecological trends.
• Assess spatial distribution of specific fish species using sampling site location coordinates.

Strengths

• Data originates from authoritative DFO Science surveys.
• Includes multiple data facets: species counts, habitat information, and precise sampling site locations.
• Focuses on freshwater fishes of conservation concern within the Great Lakes basin.

Limitations

• Specific row count, column count, and temporal coverage are not provided in the input.
• Project-specific methodology details are reported in separate documents, requiring additional lookup.
