a, Fish age, b, growth rate (cm/year). FW and MW are short for freshwater and marine wild fish, respectively. The detailed sample sizes are provided in the Source Data, and “n” represents the number of data points per graph. A Mann-Whitney U test was performed to compared fish age and growth rate between groups. Based on Monte Carlo analysis (two-sided), a p-value less than 0.05 indicates statistically significance.
