Modeled Effects of Ocean Acidification on Bristol Bay Red King Crab Yields and Profits

Model output data from a stage-structured pre-recruit model linked to a bioeconomic model forecasts the impact of ocean acidification on the Bristol Bay red king crab fishery. The National Oceanic and Atmospheric Administration produced this data, which projects yields and profits to decline over the next 50-100 years under a scenario of decreasing ocean pH. The analysis suggests limited impacts for the next 10-20 years, with effects likely masked by natural variation.

Use Cases

• Forecast long-term fishery yields based on modeled pre-recruit survival rates under ocean acidification scenarios.
• Analyze economic impacts on commercial fishing profits using the integrated bioeconomic model.
• Evaluate the sensitivity of management advice (target fishing mortality) to changes in survival rates.
• Prioritize future research on ocean acidification impacts by identifying critical timeframes (10-20 vs. 50-100 years).

Strengths

• Data is derived from a model parameterized with life history and survival data from laboratory experiments.
• Analysis integrates population dynamics, fishery harvest, and commercial profit models.
• Projections cover a specific long-term timeframe of 50-100 years.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data reflects model output, not direct empirical observations.
