  • Other The species composition and vertical distribution of limnetic zooplankton in Lake Unagi, located in Southern Kyushu, Japan, was investigated from July 1995 to September 1996. A total of twenty-five species were identified, comprising Rotifera (13 species), Cladocera (6 species) and Copepoda (6 species). Cladocera dominated the zooplankton community followed by Copepoda and Rotifera ; they represented 52.2%, 35.2% and 12.6%, respectively. A remarkable increase in the number of copepod species (6 species) was noted, although they were not previously reported in Lake Unagi. The vertical distribution study revealed that majority of the zooplankton population remained at a 0-15 m layer. The cladoceran Diaphanosoma brachyurum and copepodid and nauplii stages migrated upward at night, whereas Bosmina longirostris, Ceriodaphnia dubia, Thermocyclops hyalinus and Tropocyclops prasinus did not show such diel vertical migration.
