The dinoflagellate Noctiluca scintillans in China: A review of its distribution and role in harmful algal blooms.

The dinoflagellate Noctiluca scintillans is often reported as a worldwide HAB species and caused severe financial losses to local aquaculture. In this review, we summarized the temporal and geographical distribution of its HABs in China, as well as its position in the plankton structure. Increasing N. scintillans HABs, both frequency and coverage, have broken out in almost all Chinese coastal regions mainly from April to June, with short-term and small coverage blooms as the primary type. The HAB period seems to shift with age and latitude. Recently, increasing abundance and dominance of N. scintillans were also reported in plankton communities in Chinese coastal waters, with multiple environmental factors related. In particular, trophic relationships may play an important role in its dominance and outbreaks of HABs. However, how N. scintillans became a dominant species in China and the mechanisms responsible for its HABs require further study.
