Box plot with dot plot for the GSI values of females under five different photoperiod conditions and the winter conditions (initial group, IG) in 11 populations. The raw GSI values are shown in Table S2. A red triangle indicates the mean value in each group. The fish were kept at 24 ± 0.5 °C for 3 weeks. Black and orange asterisks indicate significantly higher and lower values compared to IG, respectively. *p < 0.05, **p < 0.01, ***p < 0.001. The raw statistical results of one-way ANOVA and Tukey–Kramer tests are shown in Tables 1 and S3
