Abstract An annotated checklist of marine and estuarine fishes of Yaku-shima Island, Kagoshima
Prefecture, southern Japan, was compiled from field and literature surveys. All registered specimens
previously recorded from Yaku-shima Island in published papers were re-examined. A total of 951
species (382 genera, 112 families, 24 orders), including 374 species that represent the first reliable
records from the island on the basis of collected specimens, are listed with citation of literature,registration numbers, sizes, localities in the island, nomenclatural and taxonomic remarks, and color
photographs if available. A new Japanese name is proposed for a bythitid, Alionematichthys piger.
Zoogeographical implications of the Yaku-shima Island ichthyofauna are discussed.
Key words: fish fauna, checklist, Yaku-shima Island, Kagoshima, Japan, Kuroshio Current.

Introduction
In 1904–1905, Mr. Robert Anderson, who
was a graduate student of Stanford University andusually studied birds, collected fishes from Yakushima and Tanega-shima Islands, Kagoshima,
Japan. His collection was sent to the United States
National Museum and Stanford University. In
1906 Jordan and Starks reported 20 species offishes, including seven new species, from these islands on the basis of Anderson’s collection. Thirteen of the 20 species were described on the basisof specimens from Yaku-shima Island, and these
are currently deposited at the Museum Support
Center of the Smithsonian Institution National
Museum of Natural History, Suitland (formerly
United States National Museum) and the California Academy of Sciences, San Francisco (allfish specimens moved from Stanford University
around 1969). These represent the oldest available
fish specimens from Yaku-shima Island.
After Jordan and Starks (1906), no comprehensive reports on fishes from Yaku-shima Island
were published for nearly 70 years until 1975.
Arai and Ida (1975) reported 143 species from
Yaku-shima and Tanega-shima Islands, 80 speciesof which were collected from Kusugawa on thenortheast coast of Yaku-shima Island. Although
Arai and Ida’s (1975) report was based on collected specimens, they gave no indication ofvoucher specimens, including registration numbers. However, most of their specimens were infact deposited at the National Museum of Natureand Science, Tokyo.
Recently, several reports on fishes from Yaku65

H. Motomura et al.

shima Island (e.g., Ichikawa et al., 1992; Kuniyasu, 1999; Matsumoto, 2001) were published by
local divers and nature guides. These were basedon underwater investigations, including underwater observations, photographs and movies, andobservation at local fish markets. Ichikawa et al.
(1992) provided a list of 580 species from Yakushima and Kuchierabu-shima Islands (the latter islocated off the northwest of Yaku-shima Island),including freshwater fishes and species reported
by Arai and Ida (1975). Ichikawa et al. (1992)
gave only Japanese and scientific names and 14
underwater photographs but no information on
observed fish sizes, localities, water depth, or
specimens of species listed. Subsequently, Kuniyasu (1999) reported 333 species from Kurio on
the southwest coast of Yaku-shima Island on thebasis of underwater observation; he also did notcollect any specimens. Matsumoto (2001–2005)
published a series of underwater photographs ofvarious Yaku-shima fish families, viz., Chaetodontidae (2001), Pomacanthidae (2002), Muraenidae(2004a), and Pomacentridae (2004b, 2005), but healso did not collect any specimens.
Since Yaku-shima Island is very importantand interesting zoogeographically (see below), we
made three large-scale Yaku-shima Expeditionsin 2008–2009 (8–13 August 2008, 28 October–4
November 2008, and 25 July–1 August 2009) toelucidate the island’s ichthyofauna and to clarify
the influence of the Kuroshio Current on the ichthyofauna of southern Japan. In the expeditions
and several small-scale surveys during this study,
4,386 specimens of 457 species of marine andestuarine fishes were collected, with 374 of the
457 species representing the first records from theisland based on collected specimens.
This paper provides a list of 951 species ofmarine and estuarine fishes (382 genera, 112 families and 24 orders) occurring off Yaku-shima Island on the basis of published papers, underwaterphotographs, and collected specimens, along withcolor photographs where available. Previously
reported specimens from Yaku-shima (Jordan andStarks, 1906; Arai and Ida, 1975) were re-identified during this study. The zoogeographical implications of the Yaku-shima Island ichthyofauna are
discussed.

Yaku-shima Island and Kuroshio Current
Yaku-shima Island is located at 30°20′N,
130°32′E, ca. 60 km off south–southwest ofOsumi Peninsula, Kagoshima Prefecture, southern
Kyushu, Japan. The island, roughly circular inshape and with an area of ca. 505 km² and several
mountains more than 1,000 m in height (highest
1,936 m), is the largest island in the Osumi Islands (and the ninth largest island in Japan). The
Osumi Islands, including Tanega-shima, Yakushima, and Kuchierabu-jima Islands, are often
treated as a part of the Ryukyu Islands, but the
Ryukyu Islands are biogeographically defined as
islands of Amami-oshima and southward. Yakushima Island, formed mostly of granite, has very
limited flatlands and in its entirety appears as one
large, steep mountain, with the mountain slope
continuing under the sea. Thus, shallow waters,coral reefs and sandy beaches are very limited;most coastal areas are occupied by rocky reefs.
Although such a monotonous environment in the
coastal areas of an oceanic island generally results
in a decrease in fish species diversity, Yaku-shimaIsland has a relatively higher diversity because
the island faces a warm, strong water current, theKuroshio Current, which brings tropical fishes
from the south.
The Kuroshio Current flows from off the eastof the Philippines to the Pacific coast of southern
Japan, via Taiwan and west of the Ryukyu Islands(Fig. 1). The northwardly flowing current off thewest of the Ryukyu Islands turns to the east andflows through the Tokara Islands (located between
Yaku-shima and Amami-oshima Islands) (Lee etal., 2001). The current then turns north again toward the Pacific coasts of the islands of Kyushu,
Shikoku, and Honshu (the main island of Japan)(Kamachi et al., 2004).
The Tokara Islands consist of 12 small islands
in a row extending ca. 160 km north to south.
There are two flow paths of the Kuroshio Current
through the Tokara Islands (Chaen and Ichikawa,
2001): the more southerly route takes the current
across the island chain from west to east around
Nakano-shima Island; and the other, more northerly, route flows along the southern coast of Yakushima Island. The current alternates between thetwo flow paths on a 30–50 days cycle. Changes inChecklist of marine and estuarine fishes of Yaku-shima Island

the flow path influence other minor water currents
in the area, especially the Osumi Branch Current flowing between Yaku-shima Island and thesouthern tip of Osumi Peninsula. During a period
when the Kuroshio Current flows around Yakushima Island, the Osumi Branch Current flows
northeastward from Yaku-shima Island to Osumi
Peninsula, but during a period when the Kuroshio
Current takes its more southerly route, the direction of the Osumi Branch current is irregularly
reversed to southwestward. So, the water currents
around Yaku-shima Island are complex, with theflow rates and directions changing with seasons,water temperatures, and winds. These factors produce a unique ichthyofauna off the island.
Materials and methods
The systematic arrangement of families follows Nelson (2006). Scientific names generally
followed Nakabo (2002) and Eschmeyer andFricke (2009), with some modifications by recent

published or unpublished taxonomic studies. Species in families are arranged in alphabetical orderby species name. Standard Japanese names (abbreviated as Jpn name) generally follow Nakabo(2002), and are transliterated using the Hepburn
system. Each species record was compiled fromvoucher specimens and literature sources related
to marine and estuarine fishes, including freshwa-

ter fishes collected from estuaries. Each voucher
specimen includes registration number, number of
specimens registered if more than one, standard
length [abbreviated as SL; sometimes total length(TL) or disc width (DW)], and locality on Yakushima Island (Fig. 2). The list of specimens is followed by literature cited. Most specimens used inpreviously published papers were re-identified inthis study, and information on SL and locality of
the re-examined specimens are provided.

Remarks: Møller et al. (2008) redescribed
Dinematichthys piger Alcock as a member of Alionematichthys, based on 2288 specimens, including several specimens from the Ryukyu Islands,
two of which were collected from Yaku-shimaIsland. The Yaku-shima specimens represent thenorthernmost records of the species. A new standard Japanese name, Hadaka-ryukyu-itachiuo, is
proposed here for the species because it can easily
be distinguished from A. riukiuensis, a congener
co-ocurring in Japan, by lacking scales above theopercular spine (vs. scales present in the latter).

[Jpn name: Okinawasangoamadai] (Fig. 190)

55 m off Kume-jima Island in 1999 (KPM–NR
29578). The photograph of the species taken at
Yaku-shima Island represents the first record of H.
fronticinctus from the island. This species is relatively common in depths of more than 50 m off
Yaku-shima Island. Specimens of the species havenever been collected from Japanese waters.

Remarks: The photographed individual has
the following characters: caudal fin forked; opercular spine smaller than pupil diameter; depthof posterior margin of maxilla less than pupil
diameter; dorsal fin with 10 spines and 13 softrays; anal fin with two spines and 12 soft rays;a blue saddle-shaped blotch on caudal peduncle
dorsally; a blue band from snout to eye; dorsal
and anal fins yellowish, with bluish green basallyand pink distally; and caudal fin yellowish, withbluish green stripes along upper and lower margins. These characters agree with description of
H. fronticinctus given by Dooley (1999). This
species is distributed in the Indo-West Pacific,
and has been known from the Philippines to the
Solomon Islands in the western Pacific (Dooley,1999). Recently, Senou et al. (2006b) reported
juveniles of this species as Hoplolatilus sp. from
Izu-oshima Island on the basis of underwater photographs (KPM–NR 31560, 62592). A juvenile ofthis species was also photographed at a depth of114

Remarks: The underwater photograph showsthat the fish has scales dorsally on the head reaching forward only to above the middle of the eye;a forked caudal fin; and a body gray dorsally,
silvery white ventrally, with distinct stripes on
the dorsal and upper lateral surfaces of the body.
The dorsal head squamation and color pattern ofthe photographed individual agree with those of
Scolopsis trilineata given by Russell (2001) andRandall (2005).
This species has been known in the western
Pacific, only from Taiwan to Tonga and Australia(Shen, 1997; Russell, 2001; Randall, 2005); thus
the photographed individual taken at Yaku-shimaIsland represents the first record of the species
from Japan and the northernmonst record for the
species. No other individuals have been observedin the island.

Terelabrus sp.
[Jpn name: None] (Fig. 388)
Remarks: The photographed individual can be
distinguished from Terelabrus sp. reported from
Hachijo-jima Island (Senou et al., 2002) and Izuoshima Island (Senou et al., 2006b) and Terelabrus rubrovittatus Randall and Fourmanoir, 1998
by having a yellow stripe between red stripes on
the lateral surface of the body (vs. yellow stripe
absent in the latter two species). Photographedindividuals taken off Kume-jima Island, Japan,
and Bali, Indonesia (deposited at KPM Fish Image Database) are identified here as the same species with the Yaku-shima Island individual. The
species is common around 60 m at Yaku-shimaIsland.

mirabilis are within the variation of characters forE. tutuilae; thus, their E. mirabilis is most likely
to be identified as E. tutuilae (M. Meguro, unpub.

Remarks: This species is similar to E. bahasa
and E. erythrosomus Shen, 1994 in overall body
appearance and general coloration, with distinct
black blotches on the pectoral-fin base. However,Enneapterygius sp. 1 has a single symphyseal
mandibular pore, whereas E. bahasa has 2–8
pores. The body, including head and fins, of mature males of Enneapterygius sp. 1 is uniformly
black, but the trunk of mature male E. bahasa isnever black. Enneapterygius sp. 1 is most likely
to be E. erythrosomus (currently known only from
Taiwan; Chiang and Chen, 2008), but comparisonof mature male coloration of the two is required.

Discussion
In this study, 951 fish species were confirmed
to occur in the marine and estuarine waters of
Yaku-shima Island, with 374 and 89 species representing the first records from the island based oncollected specimens and underwater photographs
respectively. The most speciose families of fishes
in Yaku-shima Island are listed in Table 1. The
top 24 families comprise 75.6% of the total fish
fauna. The Gobiidae and Labridae are clearly thedominant families, with a total of 208 species representing more than one-fifth of total fish fauna.
Senou et al. (2006a: table 1; 2007: table 1)
ranked the most speciose families of Ie-jima Island and the Miyako Group, the Ryukyu Islands.
There are no major differences in the ranking andnumber of species for most families among Yakushima Island, Ie-jima Island, and the Miyako
Group. In fact, the top eight families occurringin Yaku-shima and Ie-jima Islands were identical in ranking (one to eight: Gobiidae, Labridae,
Pomacentridae, Apogonidae, Serranidae, Blenniidae, Chaetodontidae, and Acanthuridae), andthe percentage of the total fish fauna that thesefamilies represent are similar (48.5% in Yakushima Island vs. 53.6% in Ie-jima Island). On the240

other hand, there are noteworthy differences in
the family ranking between Yaku-shima Islandand the Sagami Sea (Senou et al., 2006b: Table 1
and revised table as erratum attached to reprint).
The Sagami Sea is located off the Pacific coastof central Honshu, Japan, and Yaku-shima Island
is located almost midway (based on latitude) between the Sagami Sea and the Ryukyu Islands (Iejima Island and the Miyako Group). Whereas thePomacentridae was ranked as the fifth most speciose family occurring in the Sagami Sea, with 2.9%of total fish fauna, the family was ranked third
in the lists of fishes of Yaku-shima and Ie-jimaIslands, and the Miyako Group, with 6.9–9.6% of
the total fish fauna. Apogonidae, the fourth ranked
family in Yaku-shima and Ie-jima Islands, and the
Miyako Group, was ranked eighth in the Sagami
Sea. These two families are primarily tropicalfishes.
In addition, although the Myctophidae andCottidae were listed as the fourteenth and fifteenth
most speciose families respectively in the Sagami
Sea, they were not listed from Yaku-shima and Iejima Islands, and the Miyako Group. The former
was not recorded from Yaku-shima and Ie-jimaTable1. Most speciose families of fishes in Yaku-shimaIsland.

Checklist of marine and estuarine fishes of Yaku-shima Island

Islands, and the Miyako Group, because no deepwater or offshore fisheries exist there. The latter isa primarily temperate and cold water family anddoes not occur in Yaku-shima Island and southward.
These results indicate that the fish fauna of
Yaku-shima Island is more similar to that of the
Ryukyu Islands, rather than the Sagami Sea,
although cluster analyses of UPGMA (Senou
et al., 2006b: fig. 11) showed that there are two
distinctive biogeographical regions in Japanesewaters: one is the Japanese mainland and associated islands, including the Sagami Sea and Yakushima Island, and the other is the Ryukyu Islands.
Because Senou et al.’s (2006b) analysis incorporated only 567 species from Yaku-shima Island(mostly based on a list by Ichikawa et al., 1992),
similarities between the fish faunas of Yaku-shimaIsland and the Ryukyu Islands at least family
composition level were probably underestimated.
The Kuroshio Current flows from off the east of
the Philippines to the Pacific coast of southern Japan, via Taiwan and west of the Ryukyu Islands,
and regularly reaches along the coast of Yakushima Island (Fig. 1). The similarity between thefish faunas of Yaku-shima Island and the Ryukyu
Islands is most likely caused by transportationof tropical fishes, such as the above mentioned
families Apogonidae and Pomacentridae, by the
Kuroshio Current from Taiwan or China to Yakushima Island.
However, some temperate species that occur off the Japanese mainland (and often off
Taiwan) and do not occur in the Ryukyu Islands,
are well established in Yaku-shima Island. For
example, Acanthoplesiops psilogaster (Plesiopidae), Parupeneus spilurus (Mullidae), Istiblennius
enosimae (Blenniidae), Parapercis kamoharai(Pinguipedidae), Amblyeleotris fontanesii (Gobiidae), Pandaka sp. (Gobiidae), and Gymnogobius
petschiliensis (Gobiidae) are quite common at
Yaku-shima Island, but no records of these species
have been published from the Ryukyu Islands.
Furthermore, Yaku-shima Island is the southern
distributional limit of Plecoglossus altivelis altivelis (Osmeridae), a diadromous species widelydistributed around the Japanese mainland, andthis species is replaced with Plecoglossus altivelis

ryukyuensis in the Ryukyu Islands. Occurrence ofsuch species in Yaku-shima Island may be causedby the transportation of fishes (especially at larval
and juvenile stages) from southern Kyushu by
the Osumi Branch Current that irregularly occurs
between Osumi Peninsula and Yaku-shima Island,and some species possibly from Taiwan by the
Kuroshio Current (Fig. 1).
In southern Japan, several species are known
to have speciated in the north and south of theTokara Islands (e.g., Senou et al., 2006b), resulting in two sister species being allopatrically distributed in the Japanese mainland with associatedislands, including Yaku-shima Island (north of theTokara Islands), and the Ryukyu Islands (south of
the Tokara Islands). However, our surveys unexpectedly revealed that, in some cases, two sister
species occur sympatrically at Yaku-shima Island.
For example, two closely related gerreids, Gerres
equulus (primarily distributed around the Japanese mainland) and G. oyena (Ryukyu Islands);
two sparids, Acanthopagrus schlegelii (Japanese
mainland) and A. sivicolus (Ryukyu Islands); andtwo ostraciids, Ostracion immaculatus (Japanese
mainland) and O. cubicus (Ryukyu Islands) occur
at Yaku-shima Island. This is the first discovery
in southern Japan where two primarily allopatricsister species in several families occur at the sameisland.
As mentioned above, the marine and estuarine
fish fauna of Yaku-shima Island is composed ofa mixture of fishes primarily distributed in theJapanese mainland (and Taiwan) and the Ryukyu
Islands, indicating that the species composition in
Yaku-shima Island is clearly accounted for by thelocation of the island relative to the Kuroshio Current. The Kuroshio Current around Yaku-shimaIsland works not only as a kind of conveyor belt
for fishes of the Ryukyu Islands and Taiwan but
also as a strong barrier for fishes of the Japanese
mainland. The latter role of the current inhibits
fishes of Yaku-shima Island from extending theirdistribution southward to the Ryukyu Islands.
Incidentally, we found that some species
considered to be relatively rare or observed sporadically in Japanese waters, have considerablylarge populations around Yaku-shima Island. For
example, Pomadasys quadrilineatus (Haemulidae)
241

H. Motomura et al.

and Pentapodus aureofasciatus (Nemipteridae)
form numerous schools, each with more than 100
individuals, and were observed throughout theyear at various life stages off Yaku-shima Island(Motomura and Harazaki, 2007; Matsunuma etal., 2009). Although these species are common in
Taiwan and Yaku-shima Island, they have only
sporadically been collected and never observed inschools off the Pacific coast of the Japanese mainland. This suggests that the Yaku-shima Island
populations of these species probably originatedin Taiwan and/or adjacent waters, and most of thesporadically collected individuals along the Japanese mainland may have been supplied from theestablished populations at Yaku-shima Island. So,
Yaku-shima Island appears to be a major sourceof some tropical fish supply to the Pacific coast of
the Japanese mainland.
