A study conducted in spring/summer 2023-2024 to improve knowledge of maturity and spawning season in common cuttlefish Sepia officinalis. Cuttlefish were purchased from commercial fishing vessels, measured, and dissected to determine sex and maturity. Two charter surveys in Lyme Bay in September and October 2023, plus commercial samples from June-November 2024, were used to detect a recruitment pulse of juveniles.
Use Cases
- Modeling cuttlefish spawning seasonality based on maturity stage data.
- Analyzing recruitment pulses of juvenile cuttlefish based on inshore sampling.
- Studying sex-specific growth patterns based on mantle length measurements.
- Comparing maturity assessment methods from commercial and charter survey samples.
Strengths
- Data collection spanned two distinct periods: spring/summer 2023-2024 and June-November 2024.
- Two different sampling methods were trialled: charter surveys and purchases from commercial fishers.
- All specimens were identified to species level and measured for mantle length.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic bias inherent to the Western Channel and Lyme Bay sampling.
