Seasonality and occurrence of the dominant mysid Neomysis awatschensis (Brandt, 1851) in the Yura River estuary, central Sea of Japan

Those results suggest that reproduction is partially suppressed by variable and oligotrophic conditions in the Yura River estuary. Combined with the flexibility to seasonal changes in temperature and food availability, the great tolerance to acute salinity fluctuations allows N. awatschensis to maintain its population in the estuary.
