Characteristics A separate window opensReferences

These waters extend from Shimaura Island in the city of Nobeoka, Miyazaki Prefecture through the vicinities of the mouths of the Gokase and Ose rivers to the mouth of the Isuzu River. In the waters in the vicinity of Shimaura Island unfold coral reefs including rare species as well as eel grass, Halophila ovalis, wakame, Undaria undarioides, Sargassum incanum, wakame beds, and agar beds. In the river-mouth tidal mud flats of the Gokase, Hoori, and Kitagawa rivers benthic animals are abundant, and here Stenomelania rufescens and Deiratonotus japonicus are prolific. Also here are valuable species such as Luciogobius palliduse, Parapyxidognathus deianira, and Ptychognathus ishii (Ministry of the Environment, 2001). In the Totoro saltwater marshlands live common Orient clam and others (Henmi, personal communication). In addition, Biro Island is the world's largest breeding ground for Japanese murrelet, and these waters are very important since they surround the breeding colony for 8 km (Mukai, personal communication; BirdLife International, 2012). In the Port of Kadokawa Ecklonia kurome, Sargassum incanum, and other seaweed beds are found (Fukuda, personal communication). Mihokogaura (Port of Hososhima) has beds of Ecklonia kurome and Sargassum beds of Sargassum patens and others in the reef area, and eel grass beds in the area of sand and mud. The Port of Hiraiwa in the city of Hyuga is close to the southern limit of distribution of Ecklonia kurome, while the coast of the sea extending in front of Hichiya in Hyuga is close to the southern limit for Sargassum micracanthum.

* This is the species list of which meet the criteria. In that matter, this list does not include all species that inhabit the individual area.
Abbreviation in the information is as follows.
[Br/Ne] : Adjacent water of breeding area or nesting site
[Sp] : spawning area
[Ad] : species not used for analysis but add to the list because inhabit information was collected later
[Ex] : species used for analysis but considered to be possibly extinct in the EBSA region (area)
No mark : data of species distribution
