| description | The abundance of adult males, females, and copepodites, and sex ratio of a <i>Temora turbinata</i> population and seawater hydrology were studied from 2018 to 2019 in waters off northeast Taiwan, northwest Pacific Ocean. The hydrological parameters showed significant differences between sampling months caused by interactions of Kuroshio, East China Sea water, and the China Coastal Current. The highest average abundance was recorded from the June 2018 cruise with 2903.92 ± 3499.47 (inds. m<sup>−3</sup>), followed by a cruise in June 2019 with an average abundance of 1990.64 ± 1401.55 (inds. m<sup>−3</sup>). The sex ratio ranged between 0.25 and 2.33; the records were significantly higher in samples of June 2018 than during other sampling cruises (one-way ANOVA). The spatiotemporal distribution of <i>T. turbinata</i> showed a clear pattern of seasonal changes among sampling stations and distribution zones. Abundance of females and copepodites correlated significantly positive (r = 0.755, <i>p</i> < 0.001), whereas sex ratio (r = 0.247, <i>p</i> = 0.119) did not correlate significantly. The present study revealed that the abundance of <i>T. turbinate</i> was highest in June and was positively correlated with seawater temperature; furthermore, this is the first time the in situ sex ratio of <i>T. turbinata</i> in western Pacific waters has been reported. |
