Pelagic Fish Abundance in the Estuary and Gulf of St. Lawrence (2014-2023)

Fisheries and Oceans Canada provides pelagic fish abundance data from 2014 to 2023 for the Estuary and Gulf of St. Lawrence, expressed as individuals per normalized trawl set. The dataset covers 13 species including Atlantic Herring and Capelin, collected during annual August and September multidisciplinary surveys. Row and column counts are not specified in the input.

Use Cases

• Analyze abundance trends for species like Atlantic Herring and Capelin across the northern and southern Gulf regions from 2014 to 2023.
• Model spatial distribution of pelagic fish using survey data segmented by species and normalized trawl set metrics.
• Compare annual abundance data for 13 species, including Arctic Cod and Sand Lances, to assess biodiversity changes in the estuary.

Strengths

• Covers a 10-year time range from 2014 to 2023, providing a decade of temporal data.
• Includes data for 13 distinct pelagic fish species, such as Atlantic Mackerel and Rainbow Smelt.
• Data collection follows standardized protocols described in published Canadian scientific reports.

Limitations

• The dataset's sample size and number of rows are unknown, limiting assessment of statistical power.
• Data is restricted to specific annual survey months (August and September), missing other seasonal periods.
• Geographic coverage is limited to the Estuary and Gulf of St. Lawrence, not representing broader regions.
