Average Abundance

The abundance of adult males, females, and copepodites, and sex ratio of a Temora turbinata 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−3), followed by a cruise in June 2019 with an average abundance of 1990.64 ± 1401.55 (inds. m−3). 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 T. turbinata showed a clear pattern of seasonal changes among sampling stations and distribution zones. Abundance of females and copepodites correlated significantly positive (r = 0.755, p < 0.001), whereas sex ratio (r = 0.247, p = 0.119) did not correlate significantly. The present study revealed that the abundance of T. turbinate was highest in June and was positively correlated with seawater temperature; furthermore, this is the first time the in situ sex ratio of T. turbinata in western Pacific waters has been reported.

Major Nutrients

The 30 years’ annual variations of major nutrients dissolved inorganic nitrogen(DIN) and dissolved inorganic phosphorus(DIP) in Xiangshan Bay East China Sea between 1982 and 2011 were reported. The results showed that the concentrations of nitrogen and phosphorus nutrients increased year by year, consistent with the trend of nitrogen and phosphorus consumption in our country. Inorganic nitrogen was the main pollutant, then was inorganic phosphorus in Xiangshan harbor. The annual average change of DIN ranged from 0.21 to 0.76 mg∙dm-3 while DIP ranged from 0.018 to 0.054 mg∙dm-3. And the change trend of DIN and DIP was as following: winter > autumn > summer > spring. The DIN and DIP in Xiangshan horbor exceeded the standard limits greatly, the water quality in culture areas exceeded national criteria for sea water Level IV and most water qualities were inferior Level IV.

Taiwan Region

The northeastern region off Taiwan exhibits a high marine diversity favoured by the influence of northern and subtropical water masses driven by the East China Sea Water and the Kuroshio current (KC), respectively. A total of 87 species of copepods representing 36 genera were identified in present study. Calanoida was the most dominant order, while Temora turbinata (Dana, 1849), Paracalanus parvus (Claus, 1863) and Ditrichocorycaeus affinis (McMurrich, 1916) appeared as most dominant species. However, we noticed the unusual presence of the copepod Calanoides philippinensis Kitou & Tanaka, 1969 in concurrence with the dominant influence of KC, which suggests a larger intrusion of South China Sea (SCS) waters into the northeast Taiwan region. C. philippinensis is an exclusive species of the warm subtropical Pacific waters. Its presence in the northern Taiwan region may reflect a larger intrusion of warm SCS waters. We therefore suggest its potential use as a bioindicator of southern, tropical waters in the northern Taiwan area.
