Southern Gulf of St. Lawrence Atlantic Silverside Commercial Landings 1985-2022

Fisheries-dependent catch per unit effort (CPUE) data for Atlantic Silverside, calculated from commercial landings records maintained by DFO Statistical Services Unit. The dataset covers 38 years from 1985 to 2022 in the southern Gulf of St. Lawrence, with CPUE derived from total landings by number of licences and total landings by number of days landed.

Use Cases

• Analyze long-term trends in catch per unit effort (CPUE) using total landings by number of licences from 1985 to 2022.
• Model fishery efficiency by comparing total landings by number of days landed across different years.
• Assess stock status for Atlantic Silverside by integrating CPUE metrics from commercial landings data.

Strengths

• 38-year temporal coverage from 1985 to 2022 provides a long-term perspective.
• Data originates from the official DFO Statistical Services Unit, ensuring authoritative commercial landings records.
• CPUE is calculated using two distinct effort metrics: number of licences and number of days landed.

Limitations

• The dataset's row count, column count, and sample size are unknown, limiting assessment of its analytical scope.
• As fishery-dependent data, it may reflect changes in fishing practices and regulations rather than solely stock abundance.
• Specific data fields beyond the described CPUE calculations are not detailed, restricting potential analyses.
