Blue Crab Population and Biochemical Data from a Po Delta Lagoon, 116-Day Fishery

16 tonnes of blue crab biomass were captured over 116 days in the Valle Fattibello lagoon. The dataset, authored by Cristina Munari and updated in April 2026, presents an integrated analysis of the invasive Callinectes sapidus, including population dynamics, sex-specific growth, and seasonal biochemical profiles. It supports management frameworks linking invasive species mitigation with resource valorization.

Use Cases

• Modeling sex-specific growth trajectories based on the described growth rate differences between male and female crabs.
• Analyzing the relationship between environmental salinity and catchability (CPUE) for stock monitoring.
• Assessing seasonal and sex-related shifts in proximate composition and fatty acid profiles for biochemical valorization.
• Evaluating in-situ reproductive success potential based on recorded salinity levels and the percentage of ovigerous females.

Strengths

• Data integrates ecological (population dynamics, CPUE) and biochemical (proximate composition, fatty acids) analyses.
• Fishery analysis covers a specific 116-day period, yielding a concrete 16-tonne biomass figure.
• Key variables like salinity (37 PSU) and reproductive metrics (25-33% ovigerous females) are quantified.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data format is a 581.6 KB PDF, which may require extraction for computational analysis.
