Compiled data on age at 50% maturity for marine fishes.

The dataset contains information on species, length at 50% maturity (in cm, “L50_cm”) and its corresponding length type (TL = total length, SL = standard length, FL = fork length), total length at 50% maturity (in cm, “L50_TL”), mass at 50% maturity (in g, “M50_g”), age at 50% maturity (years, “Age_50”) and whether it was directly reported on the reference (“Age_50_Reference”), type of estimate, reference, location, latitude, longitude, and date.
