Rockfish Reproductive Data from California Coast, 1950s to Present

Reproductive data for rockfish species collected by the SWFSC FED along the California coast. The study originated in winter 2009 to assess spatial, environmental, and maternal effects on egg production, and includes historic data from the 1950s, 80s, and 2000s. It is maintained by the National Oceanic and Atmospheric Administration.

Use Cases

• Modeling fecundity trends over time based on historic and current data comparisons.
• Assessing spatial and environmental effects on egg production using sampling location and environmental data.
• Analyzing trends in mean size-at-age for chilipepper rockfish from the 1980s to present.
• Evaluating reader variability and error in age estimation methods.

Strengths

• Includes historic data compiled from the 1950s, 1980s, and 2000s for longitudinal comparison.
• Records multiple data types per specimen, including morphometrics, reproductive state, fecundity, condition, age, and location.
• Data collection is part of an ongoing study with a defined origin in winter 2009.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF format, which may complicate automated analysis.
