Abstract
In this paper we have enumerated nineteen unrecorded species of fishes with brief descriptions, which are to be newly added into a list of fishes of Niigata Prefecture, the Japan Sea side . We have now checked just 520 species of fishes from the waters around Niigata Prefecture.
Among the fishes listed herein, there are one basking shark, Cetorhinus maximus; one Pacific salmon, the so-called chinook or king salmon, Oncorhynchus tschawytscha, which seems to be the southern limit of distribution in the Japanese Islands four fresh water fishes chiefly transplanted from the Kanto district of the Pacific coast, such as rainbow trout, Salmo gairdnerii irideus, rose bitterling, Rhodeus ocellatus, grass carp, Ctenopharyngodon idellus and deep crussian, Carassius cuvieri; three bramid fish, Brama raii, Steinegeria rubescens, and Taractichthys longipinnis, of which the latter two are rare species and first record from the Japan Sea; a rare and noteworthy pteraclid fish, Centropholis petersi, which seems to be the eighth records of catch from the adjacent waters of Japanese Islands; seven marine fishes of subtropical or temperate-water, such as, Nemipterus virgatus, Hapalogenys nitens, Triacanthodes anomalus anomalus, Lactoria cornutus, Lagocephalus lagocephalus oceanicus, Pseudorhombus, and Poecilopsetta plinthus, of which the puffer, L. l. oceanicus, and the small flat fish, P. plinthus, have not been reported from the Japan Sea probably; and two boreal bottom-fishes, Tilesina gibbosa, and Cyclopteropsis lindbergi.
