Snow Crab Trap Survey Data from Newfoundland and Labrador, 2018-2025

Eight-year data collection from a depth-stratified random trap survey for Snow Crab in Newfoundland and Labrador inshore waters. Fisheries and Oceans Canada conducted the survey using large and small-mesh traps baited with squid, with biological sampling performed at-sea. The dataset includes only successful sets, with zero catches denoted by a 'number' of 0.

Use Cases

• Modeling Snow Crab population density based on stratified random sampling across multiple bays.
• Analyzing catch variability related to trap type (large-mesh vs. small-mesh) and soak time.
• Studying spatial and temporal trends in Snow Crab distribution across eight Newfoundland and Labrador bays from 2018 to 2025.

Strengths

• Data spans eight years (2018-2025) providing a multi-year time series.
• Survey follows a depth-stratified random design across eight specified bays, suggesting structured spatial coverage.
• Methodology details are documented, including trap specifications, bait type (squid), and fleet configuration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the surveyed inshore bays of Newfoundland and Labrador.
