(a) Annual changes in average sea surface temperature and photoperiod in Sesoko station, Okinawa, Japan. Black line indicates Sea Surface Temperature (SST) and grey line indicates Photoperiod. Error bar indicates maximum and minimum value of SST. (b) Monthly changes in mean diameter of oocytes of A. tenuis. The data are presented as mean ± SE. Significant differences (P < 0.05) are indicated with the different lower case letters. Respective oocyte stages are shown above each bar graphs.
