The present study describes the spawning ecology and early morphological development of Hemitripterus villosus. The natural spawning ground consisted of bedrock and pebbles was the intertidal coast at Taean (Chungnam) and its depth was about 5~~10 m. Spawning period was mainly from the end of October to December, when the water temperature and salinity were 6.0~~ 15.8℃ and mean 32.0‰, respectively. There were no difference of the body shape and color between female and male of Hemitripterus villosus, however its reproductive organs showed clear differences. The male had tube shaped genital papilla, which was connected with testis, and the female had seminal recepacle, which was the lower part of oviduct connected with ovary. Genital papilla of male came out of its body at spawning period and then male copulated. After copulation, female stored the sperm in its seminal recepacle and fertilized when it spawned. Fertilized eggs were reached 8 cells stage after fertilization at rearing water temperature 8.2~~14.9℃. At 29 hours after fertilization, it reached morula stage, and at 146 hours after fertilization, its embryo was clearly formated. Hatching was begun from 1,488 hours (62 days) after fertilization with 8.2~~14.9℃ water temperature. The newly hatched larvae were 12.99~~15.46mm(mean 14.16±0.65 mm) in TL (Total Length), and its mouth and anus were open. At 7 days after hatching, its yolk sac was completely absorbed and the myotomes were 15+25=40, measuring 15.23~~15.54mm(mean 15.39±0.22 mm, n=5) in TL. At 75~~80 days after hatching, it was measured mean 30.06±0.76 mm in TL, and it had reached the juvenile stage with the complete set of fin rays.

In order to investigate the possibility of yearly-harvest, we carried out growth experiment (shell height, meat weight and condition index) for of the artificial oyster spat, which suspended in three different times before the season for natural spat around coastal waters of Gyeongnam Province. Shell growth of spats suspended in June showed higher than those in April and May. In meat weight, the growth of spats was significantly elevated from October, of which significant difference was observed depending on growing farms (Gosung<Tongyeong and Koje). Using condition index, we found that the spat deployed in April and May were spawned on August or September, however, could not that in June. The estimated yield time were accounted for September on the shell height level (≥ 80 mm) and October on the meat weight level (≥ 5 g).

Egg development and morphological change of larvae of the Sakhalin sole Limanda sakhalinensis were studied by observing specimens obtained in a rearing experiment from fertilized eggs to the juvenile stage. The wild broodstock was collected in January 2010 and kept in a circular water tank (Ø1.5×1 m) at a temperature of 14.5±0.5℃. Fertilized eggs ranged from 0.72 to 0.82 mm (0.77±0.07 mm, mean±SD) in diameter. The eggs were spherical, transparent and adhesive demersal. The egg yolk was divided from the oocyte 10 min after fertilization (AF), and an embryo was formed in 36 h AF. More than 50% of the eggs hatched within 133 h AF. The mouth and anus did not open until 3.5±0.25 mm total length (TL). At 4, days after hatching (AH), the fish became larvae 3.7 to 4.2 mm (4.0±0.36 mm TL), yolk absorption was completed and the mouth began to open. The left eye moved upward and the nostril moved to the right at 39 days AH. These post-larvae ranged from 8.0 to 9.9 mm TL (8.9±1.33 mm TL). At 50 days AH, the fish became juveniles (12.4±1.20 mm TL) There were 70-72 dorsal fin rays, 55-56 anal fin rays, 11 pectoral fin rays, and 6 ventral fin rays and the juveniles adopted a benthic life.

삼세기아과 (Hemitripterinae)는 자원 보존과 분류를 위해 외부 형태와 골격 특성에 대한 정보가 필요하다. Hemitripterus villosus의 형태학적, 골학적 연구를 위해 여수시 돌산 연안에서 5개의 표본을 채집하였다. 몸과 머리의 형태는 납작하며, 피부는 작은 돌기로 덮여있어 거칠다. 몸통에 진한 갈색 무늬가 7~9개 흩어져 있다. 내부 골격은 두개골, 악골, 현수골, 설궁부, 견대부, 요대부, 척추골과 미골부로 구성되었다. 견대부 중에서 가슴지느러미를 지지하는 4개의 사출골은 넓은 모양이다. 척추골은 37~39개이며, 내장을 보호하는 늑골이 18개가 있다. 이 연구는 Hemitripterus villosus의 형태와 골격에 대한 정보를 제공함으로써 분류하는 데 기여할 것이다. The subfamily Hemitripterinae necessitates data regarding external morphology and skeletal characteristics for resource conservation and classification. To conduct morphological and osteological examinations of Hemitripterus villosus, five specimens were collected from Yeosu Dolsan-do coast. The body and head shape was flat, and the skin is rough because it is covered with small bumps. It has 7 to 9 scattered dark brown patterns on its body. The internal skeleton consisted of cranium, jaw bone, suspensorium, hyoid arch, shoulder girdle, pelvic girdle, vertebrae and caudal skeleton. The actinost that support the pectoral fins in the pectoralis major are wide. There are 37 to 39 vertebrae and there are 18 ribs to protect the internal organs. This study will contribute to the taxonomy of Hemitripterus villosus by providing information on its morphology and skeleton.

Hemitripterus villosus, a promising aquaculture fish species, is facing declining stocks. This study aims to provide normative standards for skeletal development to address persistent skeletal deformities in farmed fish. Specimens utilized in the study underwent artificial insemination with captured fish, and the resulting larvae and fry were preserved in a formalin solution. The skeletal ossification process commenced immediately after hatching, affecting the parasphenoid, premaxillary, maxillary, and dentary structures at an average total length of 13.65±0.71 mm (n=5). By sixty-five days post-hatching, ossification extended to the ethmoid and supraorbital, completing the head’s development at an average total length of 21.24±0.50 mm (n=5). Clavicle ossification occurred at seven days post-hatching, corresponding to an average total length of 14.61±0.52 mm (n=5). At forty-four days post-hatching, the ossification of 4 actinosts took place, completing the shoulder girdle, with an average total length of 18.15±0.61 mm (n=5). Vertebral ossification initiated at ten days post-hatching, with an average total length of 14.80±0.65 mm (n=5). By fifty-four days post-hatching, 39 vertebral columns were ossified, reaching an average total length of 18.67±0.54 mm (n=5). Vertebral development was complete at sixty days post-hatching, with an average total length of 20.25±0.45 mm (n=5). This study sheds light on the skeletal development of H. villosus, providing valuable standards and fundamental data for understanding skeletal deformities in this species.
