TAXONOMIC GROUP SUMMARY PLOTS

Biomass Coverage (all stocks combined) — This describes the year range of data covered in the most recent assessment for each stock, beginning in 1950. Each bar represents an individual stock, sorted vertically from largest to smallest by average biomass over the time series.

Added Productivity Time Series (top 4 individual stocks) — This describes annual surplus production (net increase of biomass plus catch) over time since 1950 for the four stocks with the highest average biomass in the taxonomy group.

Added Productivity vs. Biomass (top 4 individual stocks) — This shows annual surplus production compared to annual biomass over time (beginning in 1950) for the four stocks that contribute the most to surplus production in the taxonomy group.
