a) Median and b) interquartile range of age at maturity of NEA cod between 1930 and 2015. Calculated from the latest maturity ogives available from stock assessment (black solid line and points) and the proportions of mature-at-age reconstructed for each year from individual increments identified as spawning zones from the whole archive (blue dashed line and open points). See Fig 7 for vertical lines (1959 and 1982).
