Mean proportions of NEA cod mature-at-age (colors) calculated from individual increments from the whole archive identified as spawning zones for each year, compared to the mean proportions of mature-at-age calculated from the maturity ogives from stock assessment and aggregated by decade (facet). Error bars indicate the standard deviation of maturity ogives from spawning zones (vertical) and stock assessment (horizontal) within each decade. Point size is proportional to the number of individual increments per age class.
