한경호,김관석,이성훈,Han, Kyeong-Ho,Kim, Kwan-Seok,Lee, Sung-Hoon 한국발생생물학회 2007 발생과 생식 Vol.11 No.2

넙치 자치어의 초기 발육단계에 따른 소화관의 형태 발달과정을 관찰한 결과, 부화 직후의 전기 자어는 평균전장 $25.0{\pm}0.14\;mm$(n=20)로 입과 항문이 아직 열려 있지 않았고, 소화관은 배체와 난황 사이에 원시 소화관의 형태로 거의 직선상으로 식도에서 항문이 생길 부분까지 길게 신장되어 있는 형태였다. 부화 후 $7{\sim}8$일째 후기 자어는 평균 전장 $5.05{\pm}0.40\;mm$(n=20)로 소화관이 발달하여 먹이의 섭취활동이 활발하였으며, 소화관은 배쪽으로 팽창하여 장과 연결되어 위가 발달하기 시작하였고, 소화관의 전반부와 후반부가 구별되어 소화기관이 분화하기 시작하였다. 부화 후 $13{\sim}14$일째 후기 자어는 전장이 $6.50{\pm}0.25\;mm$(n=20)였고, 소화관은 앞부분에서부터 1회전되어 회전부분의 면적이 넓어져 있었으며, 소화관이 식도, 전장, 중장, 후장으로 완전히 분화되면서 소화관의 기본적인 구조가 확립되었다. 부화 후 30일째 개체는 전장 $12.40{\pm}0.55\;mm$(n=20)로 위는 비대하여 분문부와 유문부가 뚜렷하게 구별되었고, 소화관은 위, 전장, 중장, 후장 및 직장이 명확하게 구분되어 치어기로 이행하여 성어와 유사한 구조로 발달하였다. 부화 후 40일째 치어는 전장이 $16.15{\pm}0.85\;mm$(n=20)로 소화관 형태는 식도부, 유문부, 장의 전장, 중장, 직장이 크게 팽창되어 상대적으로 후기 자어의 소화관 형태와는 다소 차이가 있었다. Morphological changes on digestive tract were observed using Flounder, Paralichthys olivaceus to elucidate the early developmental processes. Hatched larvae, ($2.50{\pm}0.14\;mm$ in total length: TL) has not opened its mouth and anus. The digestive tract showed linear tubular form from mouth to anus extending along with yolk. On $7{\sim}8$ days from hatching, the post-larvae, ($5.05{\pm}0.40\;mm$ TL) has developed digestive tract and activated for feeding. The digestive tract expanded into dorsal side, joined to intestine, and the stomach began to develop. The digestive tract was divided into an anterior and posterior region, and began to differentiate. In the post-larvae($6.50{\pm}0.25\;mm$ TL) on $13{\sim}14$ days from hatching, the digestive tract twisted one cycle in the anterior region, the area was expanded. The digestive tract was completely differentiated into oesophagus, anterior intestine, middle intestine, posterior intestine and arranges fundamental structure. In the embryo($12.40{\pm}0.55\;mm$ TL) after 30 days from hatching, stomach became large and could be distinguished from cardia and pyloric parts apparently. The digestive tract developed similar with that of adult flounder showing clear division of stomach, anterior intestine, middle intestine, posterior intestine and rectum. In the embryo($16.15{\pm}0.85\;mm$ TL) after 40 days from hatching, esophagus, pyloric part, anterior intestine, middle intestine, and rectum have largely expanded, and thus the morphological features are somewhot different with those of post-larvae flounder.

The Genus Lagocephalus fishes were caught to study the morphological, osteological and interrelationship in the coast of Pusan, Pohang, Kyungju and Cheju-do in Korea from September, 1989 to September, 1993. Five species representing Lagocephalus in Korea redescribed to species were provided. Cluster analysis method was used for the various morphological and osteological characters to clarify the interrelationship of the species level of genera, Lagocephalus. Lagocephalus inermis was classified into subgroup Ⅰ, and L. laevigatus, L. lunaris, L. gloveri, and L. wheeleri as subgroup Ⅱ at the level of 1.25 of average taxonomic distance. Lagocephalus inermis differs from the other four congeneric species, since it shows different synapomorphic characters of the frontal, pterotic, black gill slits, and prickles. Lagocephalus inermis differs from the other four congeneric species, since it shows different synapomorphic characters of the black gill slits and prickles.

Samples were obtained from broodstork in May, 1998, while naturally fertilized embryos were maintained and the process of skeletal development was observed from larvae and juveniles. Prelarvae immediately after hatching showed an average total length of 5.38±0.41 mm (n=10), premaxillary and dentary were ossified, parasphenoid was ossified in the cranium, and centrum and caudal bone did not ossify. Prelarvae showed ossification with maxillary, articular and epihyal and branchiostegal rays of hyoid arch were ossified at 5 days after hatching with an average total length of 6.40±0.39 mm (n=10). The vertebrae began to ossify in the direction of the tail, and neural spine began to ossify above the ossified vertebra. Postlarvae showed ossification of lateral ethmoid, parietal, and caudal skeleton in the cranium when the average total length was 7.30±0.12 mm (n=10) in 8 days after hatching. At 22 days after hatching, postlarvae ossified maxillary in the cranium, and ossified endopterygoid and ectopterygoid, etc. in the palate, when the average length of 11.1±1.27 mm (n=10). At 32 days after hatching, with the average length was 12.8±1.97 mm (n=10), caudal skeleton had one additional epural bone ossification, resulting in ossification of a total of 3 epural bone to complete ossification of all spicules.

In order to study osteology on the family Platycephalidae 3 species (Platycephalus indicus; Cociella crocodila; Inegocia japonica) were collected in Yeosu city Namsan fish market and Goheung Nokdong fish market from January 2014 to October 2014, and were applied to analyzes such as osteological charcteristic. The family Platycephalidae 3 species were the same vertebrae number as 26, but P. indicus was different from C. crocodila and I. japonica by having 11~12 abodominal vertebrae and 14~15 caudal vertebrae. Both of C. crocodila and I. japonica were the same by having 10 abodominal vertebrae and 16 caudal vertebrae. Dorsal pterygiophores of P. indicus was 22 and formula of pterygiophores was 2*12111111112111111111. Anal pterygiophores which is ventral pterygiophores was 13 and it started from 11th vertebrae. C. crocodila’s dorsal pterygiophores was 19 and the formula of pterygiophores showed 2*111111111211111111. Anal pterygiophores was 11 and started from 11th vertebrae. The dorsal pterygiophores of I. japonica was 22 and the formula of pterygiophores was 2*12111111121111111111. Anal pterygiophores was counted 13 and it started from 11th vertebrae. Therefore, the pterygiophores formula on the family Platycephalidae 3 species were distinguished one another.

The taxonomic revision of the Genus Takifugu(Family Tetraodontidae) was conducted based on the specimens which were collected 15 species from the coasts of Korea Peninsula from July, 1990 to August, 1994. The various morphological and osteological characters of the Genus Takifugu in Korea were surveyed and conducted cluster analysis to clarify the interrelationship. The species relationships of 15 species of the Genus Takifugu were studied based on osteological characters, but it was difficult to grasp the exact monophyletic group with small number of apomorphic character. Takifugu poecilonotus and T. alboplumbeus were considered as they are anscestral group because of its plesiomorphic characters of the vertebrae. dorsal and anal fin ray and pterygiophors. The advanced subgroup consisting of the Takifugu rubripes, T. chinensis, T. stictonotus, T. obscurus and T. flavidus is justified by the some synapomorphic frontal, longitudinal ridges of the frontal, number of fin rays and pterygiophores.

Ocynectes maschalis Jordan et Starks caught at Pusan brook was performed in May and June 1996, describe the development of larvae and juveniles. Absorption of the yolk was completed at about 7.7 ㎜ in total length(TL), and possessed 31~33 myomeres. Flexion of the notochord started and finished at about 9.7 ㎜ in TL and about 11.5 ㎜ in TL, respectively. Aggregate numbers of all fin rays and vertebrae were completed at over 15.8 ㎜ in TL, at which time the larvae reached the juvenile stage. The pigment patten became the same as that of adults in juveniles longer than 17.5 ㎜ in TL. Vertebrate began to develop from the anterior end and to ossify posteriorly. Neural and haemal spines of vertebrae ossified always prior to the corresponding centra. Ossification of vertebrae and caudal bones was nearly completed at 15.8 ㎜ in TL.
