First record of a reticulated toadfish, Arothron reticularis (Tetraodontiformes: Tetraodontidae), in Korea

강충배,이상화,유태식,Hae-Rim Lee,한경호 한국수산과학회 2020 Fisheries and Aquatic Sciences Vol.23 No.4

A single specimen of Arothron reticularis (398mm in total length), belonging to the family Tetraodontidae, was collected in the coastal waters off Hansan island using a set net in May 2019. The morphological characteristics of the specimen are as follows: large eyes and mouth, white spots on the body, and a white line surrounding the eyes in an annular shape. A result of maximum likelihood tree showed that A. reticularis is related to A. hispidus (93.6%). We proposed the Korean name “Geu-murl-mu-nui-kkeo-kkeurl-bok,” in accordance with the characteristics of the specimen.

농어(Lateolabrax japonicus) 아가미의 형태와 미세구조

강충배,김진구,김재원,Kang, Chung-Bae,Kim, Jin-Koo,Kim, Jae-Won 한국현미경학회 2009 Applied microscopy Vol.39 No.4

Morphology of the gill in Lateolabrax japonicus was investigated after staining the gill, as a result, we found the gill is composed of gill raker, gill arch, gill filament and gill lamellae. The number of gill raker was 7~10 in the upper and 13~18 in the lower. Ultrastructure of the gill in Lateolabrax japonicus were examined by means of the light and transmission electron microscopes. The gill have primary filament and secondary filament (lamellae). The following cells are identified and described: pavement cell, pillar cell, blood cell, mucose cell and chloride cell etc. Simple epithelial layer consists of squamous epithelium contained large nucleus, intracellular organelles etc. and the surface is covered with some of microridges. The lamella pillar structures are characterized by the axial microtubules and lateral membrane interdigitations. The mucous cells were globular in shape, and had almost the mucous granules of same size with various electron density. Chloride cells contain a lot of mitochondria and specifically developed tubular systems.

한국산 바다뱀과(Ophichthidae) 어류 1미기록종, Ophichthus erabo (Jordan and Snyder, 1901)

강충배,김진석,김진구,지환성,윤문근,박진우 한국수산과학회 2019 한국수산과학회지 Vol.52 No.4

We report the first occurrence of Ophichthus erabo (Jordan and Snyder, 1901) collected in the waters around Jeju Island. The morphologic characteristics of this species include rich brown semicircular spots distributed on the head, the back, and the dorsal fins. Ophichthus erabo has a similar body color to Ophichthus polyophthalmus but can be clearly distinguished from the latter by the number of vertebrae (152-155 in O. erabo vs. 147-149 in O. polyophthalmus) and the existence of a white spot at the center of a semicircle (i.e., no white spot in O. erabo vs. a white spot in O. polyophthalmus). We suggest a new Korean name for O. erabo to be “Mul-bang-ul-ba-da-baem-gang-eo”.

A New Record of the Pacific Sleeper Shark, Somniosus pacificus (Squaliformes: Somniosidae) from the Western Margin of the East Sea, Korea

강충배,이우준,김진구,정혜경 한국어류학회 2015 한국어류학회지 Vol.27 No.1

A single specimen (192 cm total length, TL) of the Pacific sleeper shark, Somniosuspacificus, belonging to the family Somniosidae, order Squaliformes, was firstly collected from thewest margin of the East Sea, Korea in February 2008. This specimen was characterized by havinginterdorsal space, being less than the distance between the snout and first gill opening; and thedistance between the snout and first dorsal fin origin more than 45% TL; head and body has overalldark brownish. The new Korean name “Jam-sang-eo-gwa” is proposed for the family Somniosidae,and “Jam-sang-eo-sok” for the genus Somniosus, and “Jat-bit-jam-sang-eo” for the species S. pacificus.

New Record of a Moray Eel, Strophidon dorsalis (Muraenidae, Anguilliformes) from Korea

강충배,김맹진,김진구,송춘복 한국어류학회 2020 한국어류학회지 Vol.32 No.3

A single specimen of Strophidon dorsalis (1,254 mm in total length), belonging to the family Muraenidae, was firstly collected in a fish trap off the coastal waters of Jindo Island in July 2018. It was characterized by having unpatterned body coloration, thin body, slightly rounded snout, two superorbital pores, three infraorbital pores, and six mandibular pores. This species is distinguishable from a morphologically similar species, S. sathete inhabiting the Korean waters by having three infraorbital pores (vs. four in S. sathete), last infraorbital pore below an anterior part of the eye (vs. below a posterior part of the eye), body depth 3.2~4.1% in total length (vs. 1.8~3.1%), and total vertebrae 154~167 (vs. 188~200). We add S. dorsalis to the Korean fish fauna and propose a new Korean name, “Seo-mang-gom-chi” for the species.

한국 제주도에서 채집된 곰치과(Muraenidae) 어류 1 미기록종, Gymnothorax pseudothyrsoideus

강충배,송영선,박진우,김진구,정현경 한국수산과학회 2018 한국수산과학회지 Vol.51 No.3

A single specimen of Gymnothorax pseudothyrsoideus (424.0 mm TL) belonging to the family Muraenidae, order Anguilliformes, was collected from Jeju Island, Korea, for the first time. The specimen is characterized by jaws closing completely, canine teeth on jaws, teeth not exposed when mouth is closed, ovoid posterior nostril, and body color ranging from yellowish brown to brownish with small dark spots aggregating to form larger spots that from approximately four irregular rows along the body. A comparison of mitochondrial DNA 16S rRNA sequences indicated that this specimen corresponds well with G. pseudothyrsoideus (K2P distance, d=0.002) but differs from other Gymnothorax species (11.9-13.7%). Therefore, the new Korean name “Geu-mul-nun-gom-chi” is proposed for the species G. pseudothyrsoideus.

한국산 곰치과(뱀장어목) 어류 1 미기록종, Echidna nebulosa

강충배,이유진,김진구,한송헌 한국수산과학회 2022 한국수산과학회지 Vol.55 No.4

A single specimen (522.0 mm in total length) of the family Muraenidae, collected from the waters off south-western Jeju-do Island in November 2021, was identified as Echidna nebulosa on the basis of morphological and molecular methods (DNA barcoding). This species is characterized by several morphological traits as follows: 10 rounded molar, median intermaxillary, and vomerine teeth; 4 predorsal vertebrae, 50 preanal vertebrae and 123 total vertebrae; and a pale background color with two rows of 17–20 blackish brown starry blotches along the head and body. As this is the first record of E. nebulosa in Korea, we propose the new Korean names, “Dung-Geun-Ni-Gom-Chi-Sog” for the genus Echidna, and “Beol-Kkok-Gom-Chi” for E. nebulosa.

한국산 점농어(Lateolabrax maculatus ) 자치어의 골격발달과 비늘형성

강충배,명정구,김용억,김형철 한국수산과학회 2012 한국수산과학회지 Vol.45 No.3

Early osteological development of the skull, vertebral column, and fins, and squamation in the spotted sea bass, Lateolabrax maculates, were studied under extensive larval rearing conditions. The first ossification during cephalic skeleton development began with the premaxillary, dentary, and parasphenoid at 6.4 mm Total length (Notochord length 6.1 mm)and was completed by 25.2 mm TL (Standard length 20.3 mm). Ossification of the cartilaginous caudal complex started simultaneously in the urostyle and two preural centra at 12.2 mm TL (10.4 mm) and it was completely ossified by 32.0mm TL (26.4 mm). The principal caudal fin rays, with a count of 9/8, began to ossify at 11.6 mm TL (10.2 mm) and the procurrent caudal fin rays, with counts of 4 (upper) and 3 (lower), started to ossify by 12.6 mm TL (10.9 mm). Ossification of these parts was completed by 21.4 mm TL (17.5 mm). Ossification of the vertebral column was first observed in the first to fourth centra at 8.3 mm TL (7.5 mm) and was fully completed by 21.7-35.0 mm TL (17.8-29.3 mm). The pectoral girdle started to ossify by 5.6 mm TL (5.4 mm) and was completed by 26.8 mm TL (21.8 mm). Eight pectoral fin rays were ossified at 11.6 mm TL (10.2 mm) and 16-18 rays were fully ossified by 13.8 mm TL (12.0 mm). Also, the dorsal, anal, and pelvic fin rays started to ossify at 12.2 mm TL (10.4 mm) and were completed by 12.8 mm TL (11.2mm), 23.8 mm TL (19.4 mm), and 13.8 mm TL (12.0 mm), respectively. Ossification of the anal and dorsal pterygiophores initially occurred by 12.6 mm TL (10.9 mm) and 14.3 mm TL (12.2 mm), and was completed by 21.4 mm TL (17.5 mm) and 19.3 mm TL (15.9 mm), respectively. Squamation started at three centers of differentiation: the middle region of the trunk, the anterior of the caudal peduncle, and on the caudal peduncle at 23.8 mm TL (19.4 mm). The body was covered with scales, except the snout, at 57.2-60.2 mm TL (SL 47.1-49.2 mm).
