In this paper, the author presents a practical and theoretical approach to studying fish taxonomy for students and early career researchers, based on his personal experience working on the revision of threadfins-marine and freshwater fishes of the family Polynemidae. The approach is systematically arranged and described under twelve chapters, including an introduction, an insight into fish taxonomy research opportunities, and a conclusion, in the following order: Introduction; Research start-up; Writing the first taxonomic paper; Revisionary work: focus on common and widespread species; Reassessment of type specimens and original descriptions; The distributional implications of target taxa; Morphology and Ecology; Comparison between revision and review of taxonomic papers; A strategy on the order of publications; Recognizing species differences: natural aptitude or plentiful experience?; Research frontier: the numerous undescribed Southeast Asian freshwater fish species; and Conclusion.

The Duskytail Grouper, Epinephelus bleekeri (Perciformes: Serranidae), is recorded from Tanega-shima and Amami-oshima islands and the Yaeyama Islands in the Ryukyu Islands, southern Japan on the basis of six specimens (232.6-581.2 mm standard length). In addition, several records of E. bleekeri by photographs and/or observations from Kanagawa, Kochi, Ehime, Miyazaki, and Kagoshima prefectures are confirmed. Because E. bleekeri has previously been recorded from Taiwan and southward, the present specimens represent the first reliable records of the species from Japanese waters on the basis of collected specimens. Distributional implications of E. bleekeri in Japanese waters are discussed.

日本に分布するカダヤシ科グッピー属魚類には、日本各地の温泉地と琉球列島に生息するグッピー、および北海道室蘭市白老町に生息するコクチモーリーの2種が知られている。これら日本国内に生息するグッピー属魚類はいずれも人為的に導入されたものであり、本属魚類の原産地はいずれも中央アメリカである。鹿児島県の薩摩半島南部に位置する指宿市では、二反田川の南側に広がる市街を中心に多数の温泉保養施設があり、住宅地では一般家庭に温泉水が供給されている。それらの施設や住宅から排出された温泉水は、用水路を介して二反田川に流出している。鹿児島県レッドデータブックにおいて、米沢は指宿市の二反田川にコクチモーリーが生息することを目録的に報告した。しかし、本研究で指宿市のグッピー属魚類と北海道白老町産のコクチモーリーを詳細に比較したところ両者は別種であることが明らかになり、前者はPoecilia mexicana Steindachner、 1863に同定された。指宿市のP. mexicanaは二反田川の全流域にわたって、稚魚から成魚まで周年確認されており、本種は同河川で自然繁殖している。本報告では指宿市二反田川産P. mexicanaを記載するとともに、本種の成長に伴う形態の変化および性的二型を報告する。さらに本種には標準和名が与えられていないため新標準和名を提唱する。

Six specimens (39.9–81.4 mm standard length) of the Round Scorpionfish Neomerinthe erostris (Alcock, 1896) (Scorpaenidae), previously recorded from the Indo-West Pacific and in the western Pacific from Taiwan to New Caledonia and the Wallis and Futuna Islands, were collected from Uchinoura Bay, Osumi Peninsula; southern Okinawa Trough; and Iriomote Island, Yaeyama Islands, southern Japan. The six specimens represent the first records of N. erostris from Japanese waters and include the northernmost records (Uchinoura Bay) for the species. The Japanese specimens are described here in detail and the new Japanese name “Yabusame-kasago” is proposed for the species.

A single large specimen (MUFS 18880, 739 mm in standard length) of polynemid fish, Eleutheronema tetradactylum (Shaw, 1804), collected by a large set net off the mouth of Azuma River, Fukaura, Aomori, northern Japan, represents the first reliable record from Japan and northernmost record of the species. Furthermore, a lateral line squamation character on the caudal fin membrane is herein described as newly-recognized diagnostic character for the species. Eleutheronema tetradactylum is characterized as follows: four pectoral filaments; lower jaw lips restricted to posterior one-third of lower jaw, vomer with tooth plates on either side; lateral line on caudal fin membrane divided into three lines.

A single female specimen (256.4 mm standard length) of Acanthopagrus taiwanensis Iwatsuki and Carpenter, 2006, collected off Kasasa, Minami-satsuma, Kagoshima Prefecture, Japan, was characterized by the following combination of characters: 3½ scale rows between fifth dorsal-fin spine base and lateral line; 3 or 4 oblique scale rows on cheek; modally 15 total gill rakers; 3 or 4 rows of flattened molars on each side of upper and lower jaws; second anal-fin spine robust, bluntly pointed; ventral edge of infraorbitals above maxilla nearly straight; anterior edge of dorsal scaly area of head rounded; no black bars on head; a dark streak on each membrane of anal fin; and anal-fin soft rays whitish. The dorsal- head profile of the Japanese specimen was relatively straight, compared with the convex profile in the type specimens of the species. Other characters of the Japanese specimen, however, agreed well with those of A. taiwanensis given in the original description. Acanthopagrus taiwanensis is very similar to A. pacificus Iwatsuki, Kume and Yoshino, 2010, but can be distinguished from the latter by having 3 or 4 oblique scale rows on the cheek (vs. 6 or 7 in the latter), modally 15 total gill rakers (vs. 17), flattened molar teeth on each side of the upper and lower jaws (vs. rounded molariform teeth), a robust, relatively bluntly pointed second anal-fin spine (vs. acutely pointed), and whitish anal-fin soft rays (vs. blackish). Acanthopagrus taiwanensis has been previously recorded only from Taiwan, the Kagoshima specimen representing the first record from Japan and northernmost record for the species. The new standard Japanese name “Iwatsukikurodai” is proposed for the species and distributional implications of A. taiwanensis in Japanese waters discussed.

Some species of damselfishes (Pomacentridae) have a bright blue body color. The body surface of these species has scattered iridophores, which induce changes in their blue coloration. The blue color is readily converted to blackish color during formalin fixation of fresh specimens, making it difficult to take photographs of specimens of bluish damselfishes representing live coloration. In this study, an innovative method for restoring the blue coloration in formalin fixed specimens of bluish damselfishes is described. Chromatophore conditions before and after the blue coloration restoration are also illustrated. In addition, a glycerol penetration method to preserve the blue coloration of glycerin immersion preserved specimens are discussed.

The threadfin bream genus Nemipterus Swainson, 1839 (Perciformes: Nemipteridae) currently includes 29 valid Indo-West Pacific species, eight of which have been recorded from Japanese waters. During an ichthyofaunal survey of Tanega-shima Island, Osumi Islands (Kagoshima Prefecture), Japan, a single specimen (246.9 mm standard length) of the Japanese Threadfin Bream Nemipterus japonicus (Bloch, 1791) was collected at a depth of 10 m on 13 January 2020. The specimen was characterized by seven anal-fin soft rays, 47 lateral-line scales, 6 + 10 = 16 gill rakers, a moderately deep body (depth 33.9% of standard length), long pectoral fin (posterior tip vertically level with anal-fin origin), posterior tip of depressed pelvic fin reaching between anus and anal-fin origin, upper lobe of caudal fin filamentous, and body pinkish dorsally and silver ventrally, with 1 longitudinal yellow stripes on the lateral surface, and a reddish blotch on the lateral line above the pectoral fin. Although the species is widely distributed in tropical and subtropical Indo-West Pacific waters from the Red Sea and the east coast of Africa to Taiwan and the Malay Archipelago, and bears the specific and Japanese names japonicus and Nihon-itoyori, respectively, it has at no time been recorded from Japanese waters. Therefore, the present specimen of N. japonicus, described here in detail, represents the first reliable record from Japan and northernmost record of the species in the western Pacific Ocean. The specimen collected from Tanega-shima Island was most likely to have been transported from Taiwan or the Philippines by the Kuroshio Current, the species being unlikely to reproduce in Japanese waters.
