1130 juvenile Chinook salmon were captured and sampled during three consecutive winters from late September to early April. Data include size metrics, stomach fullness, condition factor, energy density, and organosomatic indices for fish originating from rivers along the east coast of Vancouver Island. The dataset accompanies a study on overwinter nutritional stress and was authored by Katie Innes.
Use Cases
- Modeling nutritional stress based on condition factor and energy density metrics
- Analyzing seasonal feeding patterns based on stomach fullness data across winter months
- Comparing physiological metrics across different river origins along Vancouver Island
Strengths
- Sample size of 1130 individual fish provides a substantial basis for analysis
- Data collection spans three consecutive winters (2020-2023), offering temporal depth
- Includes multiple physiological metrics such as length, weight, condition factor, and energy density
Limitations
- Sample sizes vary significantly between metrics (e.g., N=108 for energy density vs. N=1114 for weight)
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
