1. 2002년 10월 16∼17일에 스쿠버다이빙, 수중 촬영을 통하여 전라남도 신안군 가거도 주변 가을철 연안의 어류상을 조사한 결과 총 5목 23과 40종이 확인되었고, 지금까지 기재 된 어종 이외에 18종이 추가로 확인되었다. 2. 어종 구성으로 보면 양볼락과가 7종으로 가장 많았으며, 그 다음으로 둑중개과가 4종, 자리돔과가 3종 순이었다. 3. 가거도 주변에서 지금까지 확인된 어종들은 온대성 어종이 대부분이었지만, 그 외에 노랑자리돔, 청황베도라치 및 파랑돔 등 난류성 또는 아열대 어종이 확인되어 제주도나 독도와 마찬가지로 대마난류의 영향도 받고 있음을 나타내었다. The fish fauna in the coastal waters of Gageodo Island, South-west Sea, was investigated by SCUBA diving in October 16 and 17, 2002. The fishes observed were classified into 40 species in 23 families. In Autumn, subtropical fishes in such as families as Pomacentridae, Pomacanthidae and Apogonidae, represented 12.5% of the total, while eurythermal species represented 72.5%.

주둥치, Leiognathus nuchalis(Temminck et Schlegel)의 仔稚魚期의 形態

明正求,金容億 釜山水産大學校 1984 釜山水産大學 硏究報告 Vol.24 No.1

南海昌善海峽에서 採集된 주둥치의 仔稚魚期에 있어서의 成長에 따른 外部形態, 體形 및 內部形態의 變化를 調査한 결과는 다음과 같다. 1. 주둥치는 後期仔魚期를 경과하는 동안 體長 4.1∼6.0㎜ 範圍에서 급격한 形態變化를 나타내고 體長 12. 3㎜에서 稚魚期에 도달한다. 2. 變態期인 體長 6.0㎜가지는 體長에 비해 꼬리부분이 가장 빨리 成長하며, 그 이후는 體高가 가장 빠른 속도로 成長하고 꼬리 부분은 가장 成長이 늦어진다. 3. 대부분의 骨格은 6.0㎜까지 骨化되며, 지느러미줄기는 體長12.3㎜에서 정수에 달한다. 4. 턱니는 거의 일정하게 증가하나 咽頭齒는 體長 6.0㎜경에 급격히 증가한다. 5. 消化管은 처음에 한번 廻轉되어 있으나, 體長6.0㎜부터 곧창자 앞부분이 굽어지기 시작하여, 體長 25.2㎜에는 한번 廻轉되고 두 번 銳角形으로 굽어진 形態가 된다. The morphological changes with growth Leiognathus nuchalis were investigated. Two hundred twenty one individuals were utilized for this study and its body length varied from 1.5 to 25.2㎜. These specimens were collected in changson channel, Namhae during the summer season (June-July) in 1982 and 1983. The metamorphosis was recognized in the post larval stage between ca. 4.1㎜ and 6.0㎜ in body length. Up to metamorphosis, the tail developed faster than any other body part. However, after metamorphosis the body height developed the fastest and the tail the slowest. Metamorphosis brought about not only ossification of many elements, but also exchange of larval features to adult ones. The latter happened typically to jaw bones and preopercles. The unpaired fins developed earlier than the paired fins. the dorsal and anal fin rays were at first formed when the body length was ca. 4.1㎜, and as it attained ca. 5.8㎜, the number of the fin rays reached of the adult's ones. In The unpaired fins, the development of the caudal fin preceded that of the dorsal and anal fins. Each fin formation was completed when the body length was ca. 12.3㎜, and this post larva entered juvenile stage. Upper jaw teeth were formed only on the premaxillary. While the numbers of teeth on the jaw increased almost constantly, those on the upper and lower pharyngeal bones increased in proportion to body length with a more or less conspicuous leap when the ./body length was ca. 6.0㎜. The alimentary canal of L.nuchalis had a single winding form until the body length was 6.0㎜, and the thereafter, it became to develop a sharp bend followed by a outward second bend.

멜라닌 색소의 생합성 과정에 관여하는 것으로 알려져 있는 효소 및 관련 인자와의 상관성을 검토하기 위하여 자연산 정상넙치와 양식산 백화넙치의 肉質과 表皮, 미립자 사료와 생물먹이인 Artemia 및 Rotifer에 대하여 단백질의 함량, 멜라닌 색소생성에 고나여하는 효소의 활성, 아미노산 조성 및 비타민A와 C의 함량을 비교하였다. 정상넙치表皮는 肉質에 비하여 단백질의 함량이 높았으나, 백화넙치인 경우는 대체로 비슷한 값이었다. 사료중의 단백질 함량은 미립자 사료 중 C1이 가장 높았다. catechal oxidase의 활성은 기질과 조효소 농도의 증가와 더불러 증가하였으며, 백화 유무에 관계없이 거의유사한 값으로 나타났다. 그리고 L-dopa oxidase활성도 동일한 결과였다. 정상넙치의 유리아미노산 함량은 백화개체에 비하여 높았으며, 表皮의 경우는 정상넙치가 백화너치에 비하여 7.5배 가량 높은 값을 나타내었다. 필수아미노산의 조성으로 비교했을 때, 미립자 사료는 Artemia와 Rotifer보다 우수한 단백질원이었다. 그리고 정상넙치의 함활아미노산의 함유량은 백화넙치의 6.3배에 달하였다. 비타민A는 정상 및 백화넙치의 肉質과 表皮에서 검출되지 않았으나 비타민C는 정상인 접치表皮가 백화넙치 表皮에 비해 약 7.8배였으며, 미립자 사료는 100.83mg/100ㅎ으로서 사료 중 가장 높았다. 따라서 넙치表皮의 멜라닌색소의 생성에는 기질인 방향족 아미노산과 함황아미노산이 큰 영향을 미치는 것으로 판단되었다. The albinic phenomenon of flat-fish (Paralichthys olivaceus) was investigated by measuring protein content, tyrosinase activity, amino acid composition, and contents of vitamin A and C. These materials in the flat-fish feed-stuff were also tested. The amount of skin protein was higher than that of muscle in normal flat-fish. Catechol and L-dopa oxidase activity did not differ between normal and albinic flat-fish. The free amino acid of skin in normal flat-fish was 7.5 times that in albinic one. Sulfur-containing amino acid in normal flat-fish was also 6.3 times that in albinic ones. Vitamin A was not detected in both of flat-fish. The content of vitamin C in normal flat-fish was 7.8 times that in albinic one. The contents of protein, sulfur-containing amino acid and Vitamin C in micro-encapsulated feed (one commercial feed in Japan) were the highest among the feed-stuff used in this experiment. The melanin formation of flat-fish skin was affected by substrates such as aromatic amino acid and cofactor such as sulfur amino acid.

N/A On 11 June 1991, eggs from the brood stock of small yellow croaker (Larimichthys polyactis) were artificially fertilized using the standard dry method and were hatched. Each of the fertilized eggs (1.1-1.2 mm in diameter) had an oil globule and was transparent and buoyant. The fertilized eggs hatched in a range of water temperatures (17.5-20.3℃) 44 hrs after fertilization. The total lengths of the newly hatched larvae were 3.1-3.3 mm, and these hatchlings had 31 myotomes (10+21). Melanophores and yellow-brown chromatophores were concentrated on the head, at the ventral part of the yolk, and in the middle of the tail. Four days after hatching, the larvae completely absorbed the yolk and became flexions of 5.1-5.5 mm in total length. Fifteen days after hatching, one spine (the anterior tip of the maxillary) appeared in the upper jaw and three spines developed at the upper parts of the eyes and on the posterior part of the head. At this stage, the larvae were approximately 8.3 mm long. Thirty-nine days after hatching, juveniles (1.9-3.4 mm in total length) had a pointed tail fin. By 66 days after hatching, the juvenile fish (about 4.0-6.5 mm in total length) were similar to adult fish in body shape. The larvae of L. polyactis could be distinguished from those of L. croacea by two distinct characteristics: the large number of vertebrae (28-29), and a relatively small bony ridge on the occipital region of the head.

The effect of delayed initial feeding (1, 3, 5, 7 days) and starvation on morphological change, mortality and cannibalism on larvae of Siniperca scheneri was examined by laboratory rearing. The larvae of S. scherzeri began to feed on Artemia nauplii at 4 days after hatching. In case of unfed and 7-days delayed groups, all of the larvae died at 12 days after hatching. The larvae of 1 day delayed feeding survived and grew as almost same as the control group, and 3-days delayed groups showed 33% survival rate at the end of experiment (12 days after hatching). In case of the unfed group, total length of the starved larvae showed lower growth rate than the control group, and they did not reached at the same size of the larvae of the control group. Cannibalism were more common in the unfed group and the delayed fed group than the control group. The highest rate of daily mortality caused by cannibalism in the delayed fed group was 23% at 8 days after hatching.

2016년 4월, 경남 통영시 신봉천에서 채집한 어미 사백어 (평균전장 4.6 mm, n=16)를 모래와 돌을 바닥에 깐 실험 수조 (60 (L)×30 (W)×30 (H) cm)에 수용하고, 산란행동 및 수정난의 발생과 부화자어의 형태를 관찰하였다. 사백어 어미는 모래 위의 돌 아래에 구멍을 파고 들어가 산란하고, 부화할 때까지 수정난을 보호하는 행동을 보였다. 수정난은 곤봉형 (장경 3.2~3.4 mm, 단경 0.6~0.8 mm, n=10)이며 지름이 2~3 cm (원형 또는 타원형)인 난괴를 이루어 돌의 천정에 매달려서 발생하였다. 수온 18~20℃하에서 눈이 생긴 수정난 (eyed egg)은 168시간 후에 부화하였다. 부화자어는 투명하며 전장이 4.1~4.4 mm (n=5)이고, 배에는 투명한 난황을 가지고 있었으며 32~33개 (12~13+20)의 근절이 발달해 있었다. 부화 후 3일째, 전장 4.9 mm 자어는 머리의 아래쪽에 입이 열리며 직장이 발달하였다. 전장 난황을 흡수한 전장 5.2mm 후기자어는 부레 등쪽과 직장 위에 흑색소포가 발달하며 꼬리의 아래 정중선을 따라서 흑색 소포가 줄지어 발달하였다. On April. 2016, the anadromous icy goby caught at Shinbong-cheon, Tongyeong shi, Gyeongsangnam-do transported to the laboratory of Korea Institute of Ocean Science and Technology (KIOST) and observed spawning behavior and egg development and larvae. In aquarium, males make the nest under stone and waiting female entering. Fertilized eggs attached under the stone in the nest. Male protected the fertilized eggs until hatching. The size of the club-shaped eggs were 3.2~3.4 mm in the major axis and 0.6~0.8 mm in minor axis (n=10). The eyed eggs were hatched after 168 hrs in a range of water temperatures (18.0~20.0℃). The total lengths of newly hatched larvae were 4.1~4.4 mm (n=5) and these larvae had 32~33 (12~13+20) myotomes and transparent oval yolk. Three days after hatching, the pre-larva (4.9 mm in total length) has opening mouth and rectum. Post-larva with 5.2 mm total length have melanophore on air bladder, rectum, base of membranous caudal fin and 9~10 melanophores ventral row on the tail.
