Estimated parameters ± standard error for the von Bertalanffy growth model and the generalized linear model quantifying the length-at-first-maturity for each area.

Length where 50% (L50) and 95% (L95) of herring were mature and numbers of observation (N) with valid data are given for each area. Growth data from Lysefjorden was not sufficient to estimate growth model parameters. Due to missing of mature herring (Lysefjorden) and immature herring (Landvikvannet and Limfjorden), no maturity probabilities could be calculated.
