| Abstract |
A survey on the occurrence of jellyfish was conducted from 1992 to 2024 at the Port of Nagoya Garden Pier, located at the far end of Ise Bay in Japan. A total of 13 species of jellyfish was found, including nine species of Cnidarian jellyfish（ seven species of Hydrozoa and two species of Scyphozoa） and four species of Ctenophora jellyfish（ two species of Tentaculata and two species of Nuda）. The number of species collected in this study was the highest between February and May, then decreased until June. No jellyfish were collected between July and August, however, the number of collected species increased again between October and January. No collection of species in summer （between July and August） could be attributed either to the extreme high water temperature at the survey area where no jellyfish species could inhabit, or to technical difficulties in collecting jellyfish due to the low salinity of the surface water by the inflow of river water, formation of seasonal thermocline, or turbidity of the surface water caused by the phytoplankton bloom. |
