Eastern Baltic cod size at maturity and body condition
The dataset includes time series (1991-2021) of two biological indicators characterizing health of the Eastern Baltic cod (Gadus morhua) stock. i) Size at maturity (L50, in cm) is the length at which half of the population have become mature. It is calculated for female and male fish combined. Furth...
