Pacific Cod Larval Size and Behavior Under Elevated CO2, 2015-2016

NOAA laboratory experiments from February 2015 to July 2016 analyzed Pacific cod larvae sensitivity to elevated carbon dioxide levels. The dataset includes measurements of larval phototaxis behavior, growth, lipid levels, and fatty acid composition under varying CO2 concentrations and feeding treatments. These experiments indicate stage-specific sensitivity of Pacific cod to ocean acidification effects.

Use Cases

• Modeling larval fish growth trajectories based on CO2 exposure levels and feeding regimes described in the study
• Analyzing behavioral changes in phototaxis based on light gradient experiments under different CO2 conditions
• Investigating the relationship between CO2 levels and lipid/fatty acid composition in larval fish over developmental stages
• Comparing stage-specific sensitivity (2-week vs 5-week) to ocean acidification effects on fish physiology

Strengths

• Data from controlled laboratory experiments with specific CO2 levels (~500, 600, 1500, 1700, 2250 μatm)
• Multi-faceted analysis covering behavior (phototaxis), growth, lipid levels, and fatty acid composition
• Explicit temporal coverage from 2015-02-12 to 2016-07-02

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is from laboratory conditions; applicability to natural ocean environments may require further validation
