On November 9, 2022, a goatfish (Mullidae) that had not been previously reported in Korea was collected during offshore fisheries resources research near Jeju Island. Based on the morphological identification, this goatfish was identified as the genus Upeneus owing to the presence of palatine teeth and vomerine teeth, as well as the proximal part of anterior part of second dorsal fin. Additionally, through molecular identification, the previously unreported goatfish was identified as U. subvittatus with a 99.8% match in the mtDNA COI region. Goatfish U. subvittatus has no patterns on its body and dark bands on both the lower and upper caudal fins, making it well distinguishable from the four species of genus Upeneus reported in Korea. U. vittatus, reported in Japan, showed morphological differences from U. subvittatus in that the dark band on the lower lobe of the caudal fin was wider, and longitudinal stripes were present on the body. Based on the morphological characteristics of U. subvittatus, we suggest a new Korean name, "Jul-mu-nui-kko-li-chog-su".

Two specimens of Upeneus tragula were firstly collected from Jeju Island, Korea. This species is characterized by having pectoral fin rays 13, lateral line 29, first gill rackers 5+14, both lobes of caudal fin with dark bands, ventral part of body with numerous blackish-brown dots, and upper part of first and second dorsal fin dark brown. It is easily distinguished from three other Korean Upeneus species in having both lobes of caudal fin with dark bands (vs. no band in U. sulphureus; only upper lobe with dark bands in both U. moluccensis and U. japonicus). We suggest the new Korean name "Keom-eun-jul-chok-su" for this species.

Seven species of the order Perciformes collected from coastal waters of Cheju Island, Korea were redescribed as new to Korean fish fauna. They are as follows: Girella melanichthys (Richardson) and Kyposus bigibbus Lacepede of the family Kyphosidae; Chaetodon wiebeli Kaup of Chaetodontidae; Istigobius campbelli (Jordan and Snyder) of Gobiidae; Gymnapogon japonicus Regan of Apogonidae; Parupeneus chrysoplueron (Temminck and Schlegel) of Mullidae; Nemipterus japonicus (Bloch) of Nemipteridae.

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.
