A single specimen (213.5 mm SL) of the epaullete surgeonfish, Acanthurus nigricauda Dunker and Mohr, belonging to the family Acanthuridae was collected by a set net in coastal waters of Busan, Korea. The species has a distinctive dark band above pectoral fin and on mid-lateral part of caudal peduncle. We describe this species as new to Korean fish fauna and propose its new Korean name, "Yang-jwi-dom".

A single specimen (351.1 mm SL) of the sleek unicornfish, Naso hexacanthus, belonging to Acanthuridae was firstly collected from the coastal waters of Jeju Island, Korea. The species is characterized by having brownish vertical bands on the dorsal fin and two pale purple bony plates on caudal peduncle. We add this species to the Korean fish fauna and propose its new Korean name, "Nam-bang-pyo-mun-jwi-chi."

A rare species of unicornfishes, Naso lituratus (Schneider) was recently collected from coastal waters in Cheju-do, Korea. This species was described and figured as first record from Korea. A key of three species belonging to the genus Naso from Korea is presented.

The Yellowfin surgeonfish, Acanthurus xanthopterus was reported as the first confirmed record from Korea based on a single specimen (332.6 mm SL) collected from the coast from Geomundo Island. It is characterized by having a longitudinal yellowish band in front of eye, dorsal and anal fins with 4 bluish stripes, and broad yellowish bar distally on pectoral fin. The new Korean name, "No-rang-munui-yang-jwi-dom", is proposed for the species.

Here, we present the first morphological description of a larval Naso hexacanthus (5.2 mm in body length) from the East China Sea identified by cytochrome c oxidase subunit I (COI) barcoding. The larva had a kite-shaped body with long serrated first spine of dorsal and anal fins. There were four melanophores on the base of the anal fin, dense melanophores on the caudal peduncle, and scattered melanophores on the surface of the brain. There was one small spine on the snout and behind each eye, with serrations on the head, top of the eye, inner- and outer-preopercle, and on the lower part and side of the opercle. The morphological characteristics of larval N. hexacanthus identified by COI barcoding will be useful for species identification of larval fish.

Background: The biological information of fish, which include reproduction, is the prerequisite and the basis for the assessment of fisheries. Methods: The aim of this work was to know the reproductive biology with the first sexual maturity (TL₅₀) and the spawning period for 58 mainly fish species in the waters around La Réunion Island (Western Indian Ocean). Twenty families belonging to the Actinopterygii were represented (acanthuridae, berycidae, bramidae, carangidae, cirrhitidae, gempylidae, holocentridae, kyphosidae, labridae, lethrinidae, lutjanidae, malacanthidae, monacanthidae, mullidae, polymixiidae, pomacentridae, scaridae, scorpaenidae, serranidae, sparidae; 56 species; n = 9,751) and two families belonging to the Elasmobranchii (squalidae, centrophoridae; 2 species; n = 781) were sampled. Between 2014 and 2022, 10,532 individuals were sampled covering the maximum months number to follow the reproduction periods of these species. Results: TL₅₀ for the males and the females, respectively, ranged from 103.9 cm (Acanthurus triostegus) to 1,119.3 cm (Thyrsitoides marleyi) and from 111.7 cm (A. triostegus) to 613.1 cm (Centrophorus moluccensis). The reproduction period could be very different between the species from the very tight peak to a large peak covered all months. Conclusions: Most species breed between October and March but it was not the trend for all species around La Réunion Island.
