A taxonomic examination of 3,108 specimens of mesopelagic fishes, collected around the Ogasawara Islands in December 2010 by a beam trawl net operated from the T/S Oshoro-maru, Hokkaido University, Japan, resulted in the recognition of 99 species representing 34 families and 65 genera. Descriptions are provided for all species, two of them〔 a stomiid Eustomias braueri Zugmayer, 1911 and linophrynid Haplophryne mollis (Brauer, 1902)〕 being new records for Japan. Three species, a stomiid Eustomias sp., trachipterid Desmodema sp. and oneirodid Oneirodes sp., could not be identified at the species level

We examined the salinity tolerance of a small aquatic beetle species, Hygrotus impressopunctatus (Dytiscidae), collected from the Kuril Islands. All beetles in seawater died by the 13th day, and 21 out of 54 beetles were still alive in freshwater on the 13th day. One beetle survived in seawater for at least 12 days. Over 50% of the beetles survived the first four days in seawater, and their survival was almost the same as those in freshwater. The mean survival time of the beetles in seawater was 6.2 days. This study suggests that H. impressopunctatus could disperse via seawater, although their survival was significantly better in freshwater.
