A multigenerational experiment exposed mature Atlantic cod broodstock to crude oil for 20 days during late gametogenesis. The dataset includes housing conditions, mortality, morphometrics, water chemistry, egg body burden, sperm quality, and embryo development metrics. Research was conducted at Norwegian aquaculture stations with approval from the Norwegian Animal Research Authority.
Use Cases
- Analyze correlations between polycyclic aromatic hydrocarbon body burden in eggs and subsequent embryo hatching success or axial deformation.
- Model the impact of water-soluble fraction exposure on sperm quality parameters to assess male gamete viability.
- Investigate maternal transfer of crude oil compounds by linking parental exposure data to offspring cardiotoxicity and morphology measurements.
- Assess environmental risk by comparing polycyclic aromatic hydrocarbon and total extractable organic material levels in water chemistry to observed multigenerational effects.
Strengths
- Data originates from a controlled 20-day exposure experiment conducted at established research stations.
- Includes multiple data types: environmental (temperature, oxygen), chemical (PAHs, TEOM), biological (mortality, morphometrics), and developmental (hatching, cardiotoxicity).
- Research protocol was approved by the Norwegian Animal Research Authority (ID 22461), indicating ethical oversight.
Limitations
- Sample size and number of replicates for the exposed and control groups are not specified, limiting statistical power assessment.
- The dataset's temporal scope is confined to a single, defined exposure period and subsequent embryo development, not long-term population monitoring.
- Geographic coverage is limited to a specific Norwegian aquaculture research context, which may not represent all Atlantic cod populations.
