Fishes collected from the Shinbori River in Kochi City, with a new record of Hippichthys (Hippichthys) heptagonus from Kochi Prefecture

Abstract

Fishes from the Shinbori River in central Kochi City were studied. Nine specimens confirmed the occurrence of Lates japonicus, one of the critically endangered fishes of Kochi Prefecture. Four specimens of Eleotris oxycephala designated as one of the near endangered fishes of Kochi Prefecture were collected. In addition, a pipefish Hippichthys (Hippichthys) heptagonus was first recorded from Kochi Prefecture, representing the northernmost record of this species. The occurrence of L. japonicus and pipefishes seemed to be closely related with Zostera japonica growing on the riverbed.
