This study aimed to confirm that the lateral lines of fish indicate water temperature, water pressure, water flow, and sound waves by conducting a direct experiment. To confirm the superiority of fish lateral lines to detect material stimuli after the experimental study of the fish lateral line's sensation function, the lateral line's tissue was expanded and the shape of the lateral side of the fish was created using a 3-D printer to realize the lateral stripe parity. The amplification effect was confirmed by measuring the sound waves, which was the material stimulus of the lateral diagonal parabola. This proved that fish lateral lines are biotechnologically superior sensory organs.

Twenty seven species of pufferfishes (family Tetraodontidae) have been examined to find their generic characters based on olfactory organ, lateral line system, prickles, body form and color characters of specimens collected in 20 places along the coast of Korea from September, 1989 to July, 1994. Based on nostril shape, the genera of Takifugu, Lagocephalus, Plurancanthus, Spheoides and Feroxodon have two nostrils, and those of Ephippion and Canthigaster have a single nostril or nasal tentacle, while Boesernanichthys, Arothron and Chelonodon have no nostril. In the genera of Lagocephalus, Spheoides, Boesemanichthys, Arothron and Feroxodon have only a single well-developed lateral line on the body, in those of Takifugu and Plurancanthus usually have two lateral lines, and those of Chelonodon and Ephippion have two lateral lines merged on the caudal peduncle. Based on the lateral line system and olfactory organ, genus Canthigaster has different characters from the other genera of the family Tetraodontidae. In Ephippion guttifer, the prickles on the dorsal and lateral of the body are enormously enlarged into plates forming a partial carapace. Of the 22 species which have prickly spines, the genera, Lagocephalus, Takifugu stictonotus and Arothron Stellatus have the larger ventral pricklyy spines than the dorsal ones. In genera Lagocephalus most of the species have prickly spines that coverd both the back and belly, while L. inermis has no prickly spines.

A single specimen of Carangoides oblongus (133.8 mm SL) belonging to the family Carangidae was firstly collected by a set net from the coastal waters of Jeju Island, Korea. This species resembles Carangoides dinema, but the former is morphologically distinguishable from the latter by lateral line being shorter than straight part, the number of lateral line scutes (37~45 in C. oblongus vs. 20~30 in C. dinema), second dorsal fin rays (20~22 vs. 17~19), and anal fin rays (18~19 vs. 15~17). We newly add this species to the Korean fish fauna and propose its new Korean name "Chae-jjik-yu-jeon-gaeng-i".

그물베도라치 Dictyosoma burgeri는 농어목 황줄베도라치과 그물베도라치속에 속하는 어류로서 우리 나라와 일본 연안의 암초지대와 조간대 상부 조수 웅덩이에 분포하는 정착성 어종이다. 몸에는 옆줄과 수직방향으로 직선이 그어져 있고 세로줄의 점액공이 있어 옆구리는 그물 모양을 나타낸다(정, 1977). 그물베도라치는 암컷이 약 2.1 mm의 덩어리진 침성점착란을 산란하고, 수정 후에는 수컷이 몸으로 난괴를 감싸 부화할 때까지 보호한다(단원 과 도진, 1972). (중략)

Psenes maculatus and P. cyanophrys of family Nomeidae were collected for the first time off the coast of Tongyeong, Kyongsangnam-do, Korea. Specimens were catched with drifting seaweed patches on June and July, 1998. Young Psenes maculatus has six black bands ('<' shape) on the body, and 'Ttimul-reung-dom' is proposed as the Korean name. Psenes cyanophrys differs from P. pellucidus in having a compressed oval body shape scales on the check, and 16 longitudinal lines on the body. 'Jul-mu-nui-mul-reung-dom' is proposed as the Korean name.

Two specimens of Opistognathus iyonis of Family Opistognathidae were collected for the first time at Chwasari Islands, Yokchi-myon, Tongyong-shi, Kyongsangnam-do, Korea. Specimens were catched by fishing on June and Oct. 1998. Opistognathus iyonis was characterized by having large mouth, big eye located anterior part of the head, large black spot on the dorsal fin and lateral line running close below base of dorsal fin. A new Korean name "Huk-Jom-Hu-Ak-Chi" is proposed for this species.

On May 12, 2023, a juvenile specimen (37.6 mm in standard length) belonging to the order Aulopiformes was collected from southern Yokjido, Tongyeong, Korea, using a Bongo net. The specimen was identified as the member of the family Scopelarchidae in having a slender body, a large mouth, large tube-like eyes, a long anal fin base, a developed adipose fin and no photophores on body. Finally, we identify the specimen as Scopelarchoides danae Johnson, 1974 in having 8 dorsal fin rays, 20 pectoral fin rays, 9 pelvic fin rays, 26 anal fin rays, dorsal fin located anteriorly than pelvic fin, and two large pigments below the pectoral fin and posterior to the pelvic fin. Scopelarchoides danae is distinguished from Scopelarchoides signifer in having less dorsal fin rays (8 vs. 9~10) and pectoral fin rays (20 vs. 22~25). The species differs from Scopelarchus guentheri and Scopelarchus analis in that it has no stripes along the both upper and lower of lateral line, and from Scopelarchus michaelsarsi in that it has more anal fin rays (26 vs. 18~21). Because this is the first occurrence among Korean fish fauna, we present its detailed morphological traits, and its new Korean name as "Nun-bang-ul-mae-tung-i".

This study was conducted to observe the spawning behavior and early life history of chinese minnow, Rhynchocypris oxycephalus reared in the laboratory. The spawning period of Rhynchocypris oxycephalus is from May to June in nature. The eggs of Rhynchocypris oxycephalus were spawned on the sand and surface of the gravel. The fertilization eggs were demersal in shape and adhesive, released as a clump forming a thin layer and their diameter were 1.70~1.90mm (mean 1.80 mm, n=20). Hatching of eggs was started in 88 hour 45 minute after fertilization at water temperature $19{\pm}0.5^{\circ}C$ and finished in 90 hour. Newly-hatched larvae were measured 4.87~5.02 mm in total length (TL, mean 4.94 mm), mouth and anus were not opened. 6 days old larvae were 6.32~6.56 mm in TL (mean 6.44 mm). Yolk sac was almost absorbed, mouth and anus was began to open. 13 days old larvae were 6.74~6.91 mm in TL (mean 6.82 mm). Part of Dorsal fin was began to rising and myomere number was 15+23=38. 25 days after hatching, total length of larvae was 8.45~8.60 mm (mean 8.52 mm). Dorsal and anal fin rays became differentiated, and also caudal part of the notocord flexion was achieved at $45^{\circ}C$. In the time, growth rate was higher than the other stage. Aggregate numbers of all fin rays were completed at 16.39~16.57 mm in TL (60 days after hatching), at which time the larvae reached the juvenile stage, but fin-fold on ventral was remained yet. External features of adult specimens were almost completed at 80 day old juveniles (18.69~18.87 mm in TL).
