Southern Gulf of St. Lawrence Sea Scallop Landings and CPUE Data

Fisheries and Oceans Canada provides data on landings, fishing effort, and catch per unit effort (CPUE) for sea scallop (_Placopecten magellanicus_) stock assessments in the southern Gulf of St. Lawrence. The dataset contains corrected information from DFO annual reports, logbooks, purchase slips, and published assessments, with data prior to 1947 representing combined landings. It was used in a peer review meeting for the Limit Reference Point and Population Model Review held on November 1-2, 2023.

Use Cases

• Modeling sea scallop population dynamics based on historical landings and effort data.
• Calculating limit reference points for fisheries management based on catch per unit effort (CPUE) trends.
• Analyzing fishing effort patterns within Scallop Fishing Areas (SFAs) 22 and 24.
• Comparing corrected data from logbooks and purchase slips with published assessment reports.

Strengths

• Data is corrected and integrated from multiple authoritative DFO sources, including annual reports, logbooks, and purchase slips.
• Specifically focuses on the core scallop habitat within Scallop Fishing Areas (SFAs) 22 and 24 in the southern Gulf of St. Lawrence.
• Includes calculated catch per unit effort (CPUE) metrics from DFO's Science Branch.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data prior to 1947 cannot be attributed to individual Scallop Fishing Areas (SFAs).
