“…For instance, a reduction in the abundance of Acartia tonsa contributed to a decline in the zooplanktivorous bay anchovy ( Anchoa mitchilli ) and menhaden ( Brevoortia tyrannus ) in the Maryland portion of Chesapeake Bay (Kimmel, Boynton & Roman, 2012). In situ research confirmed that large-scale harmful algal blooms could decrease the abundance of copepods, and simultaneously increase the abundance and dominance of jellyfish (Lin et al, 2014). In this study, we found that the relative abundance of jellyfish increased during the GTP; therefore, we suggest that these large-scale macro-algal blooms probably promote the widespread occurrence of jellyfish in the context of global change.…”

Large-scale macro-algal blooms ofUlva prolifera(also called green tides) have appeared each summer since 2008 in the western Yellow Sea. In this study, we investigated the temporal variability in zooplankton community in the western Yellow Sea and its possible links to green tides using data from a long-term plankton survey off the coast of Qingdao, China. Environmental conditions observed in the study area during the green tide period (GTP: June–August, 2008–2013) were compared to the non-green tide period (NGTP: June–August, 2005–2007), to support the contention that variations observed in zooplankton community may be attributed to the green tides, as opposed to natural climatic or environmental variations. Zooplankton assemblage structure observed during the GTP was then compared to the NGTP. Significant variations were detected both in zooplankton abundance and assemblage structure between the two defined periods. The abundance of zooplankton, mainly copepods, was significantly decreased during the GTP. Meanwhile, the relative abundance of copepods decreased by approximately 10% and that of gelatinous zooplankton, including appendicularians, chaetognaths, and medusae, almost doubled (ca. increased by 6.4%). The dominant species of meroplankton completely changed, specifically, polychaeta, and echinoderm larvae were more dominant than decapod and bivalve larvae. With regard to zooplankton size structure, the NGTP showed a higher size diversity with more small-sized organisms, while the GTP showed a lower size diversity in the community. According to general linear models, the interannual variation in summer zooplankton abundance was significantly correlated with green tides. These results indicate that the temporal changes in zooplankton community may have a close link to the green tides.

“…In our study, exposure to P. donghaiense (~10 4 cell mL −1 , the approximate algal density in blooms in the field) and K. mikimotoi (~10 3 cell mL −1 ) significantly decreased survival rates of C. sinicus adults (80%). In an in situ study, Lin et al (2014) also found that nearly 20% of C. sinicus adults died during peak phases of the P. donghaiense bloom in the ECS. However, our results indicated that nauplii were more vulnerable (>50% mortality rate) to P. donghaiense and K. mikimotoi than adults and copepodites during the 16 days of the experiment.…”

“…Thus, the habitat and recruitment stages of C. sinicus overlap with the location and timing of outbreaks of P. donghaiense and K. mikimotoi . Field studies have shown that copepod abundance significantly decreased in the vicinity of P. donghaiense blooms (Lin et al , 2014), but the reason for this decline is poorly understood. We hypothesize that the decreased abundance of C. sinicus may be closely related to adult survival, reproduction and larval recruitment during blooms.…”

Large-scale blooms of dinoflagellates, such as Prorocentrum donghaiense and Karenia mikimotoi, have occurred frequently in the East China Sea (ECS) in recent decades. However, little is known about their effects on the entire life history of copepods. Under laboratory conditions, we investigated the effects of these two common dinoflagellates on the survival of Calanus sinicus individuals at different stages and on reproduction of this copepod. Compared with the control treatment (Skeletonema costatum), the presence of P. donghaiense and K. mikimotoi decreased the survival rates of adults and nauplii during the 16 days of the experiment. Survival of nauplii decreased to 49% and 48%, respectively, relative to the nearly 80% survival of adults. Among the six stages of nauplii, individuals at NII and NIII were more susceptible to P. donghaiense and K. mikimotoi. Lower egg production rates were also observed when copepods were exposed to P. donghaiense and K. mikimotoi, and hatching success decreased only with exposure to P. donghaiense. These results suggest that blooms of the two common dinoflagellates may have detrimental effects on the survival of nauplii and the reproduction of C. sinicus, which may pose a major threat to the recruitment of C. sinicus.

In recent years, harmful algal blooms (HABs) have occurred frequently along the coast of China and have caused massive shellfish mortality. However, little is known about the impacts of HABs on the metamorphosis of shellfish. In this study, the effects of 4 typical harmful algae species present in Chinese waters (Karenia mikimotoi, Alexandrium catenella, Aureococcus anophagefferens, and Prorocentrum donghaiense) on the survival and metamorphosis of abalone Haliotis discus hannai larvae were investigated. After 96 h of treatment, un-metamorphosed larvae (veligers) were significantly affected by K. mikimotoi, A. catenella, and P. donghaiense, as mean ± SD survival rates were 5.2 ± 2.1, 27.7 ± 1.4, and 63.8 ± 6.9%, respectively, compared with 86.0 ± 4.1% for the control treatment (the non-toxic alga Skeletonema costatum). Survival rates of metamorphosed larvae were significantly affected by K. mikimotoi, A. catenella, and A. anophagefferens (4.5 ± 2.8, 22.3 ± 5.8, and 26.5 ± 3.6%, respectively, compared with 46.2 ± 1.3% for the control), and metamorphosis was significantly inhibited by K. mikimotoi and A. catenella (5.0 ± 2.2 and 24.5 ± 3.1%, respectively, compared with 49.3 ± 1.5% for the control). A. anophagefferens was more toxic to metamorphosed larvae than to un-metamorphosed larvae. These results suggest that all 4 species of harmful algae have detrimental effects on the metamorphosis of H. discus hannai and that K. mikimotoi and A. catenella are more toxic to abalone larvae than A. anophagefferens and P. donghaiense.
