海南周邊海域의 참굴, Crassostrea gigas 浮遊幼生의 出現 및 生存率

梁東旭,朴炅洋 木浦大學校 沿岸環境硏究所 1996 沿岸環境硏究 Vol.13 No.1

The occurrence and survival rate of the larvae Pacific oyster, Crassostrea gigas, plankton samples were collected at the coast of Haenam during the period from June to September both in 1994 and 1995. Among these samples, oyster larvae were identified and divided into three stages: D-shape, Umbo larvae and Mature larvae. During the research period, the advent of D-shaped larvae had two peaks in late June and mid August. The advent of larvae peak also occurred twice both in Umbo-shape larvae and mature larvae: the former found both on late June to early September and mid August to late August, and the latter on early July and late August, respectively. All these peaks were appeared under condition of 22.0∼25.2℃ and 30.58∼34.34‰ of salinity. During the transition period among three developing stages, the instantaneous death rate ranged from 0.20 to 0.27 in the D-shape to Umbo-shape period, and from 0.27 to 0.56 in the Umbo to Mature larvae. The daily survival and death rates varied with 0.74∼0.88, 0.12∼0.24 in the D-shape to Umbo-shape period and 0.25∼0.70, 0.24∼0.42 in the Umbo to Mature larvae, respectively. The mean survival rates of D- to Umbo-shape period varied from 33.62 to 38.69%, and in the Umbo to Mature larvae period from 13.58∼14.63, respectively. The time lag between D- and Umbo-shape larval was 5 to 8 days. In addition, 3 to 10 days were required for Umbo-shape larvae to develop into the Mature larvae. The elapsed days from the advent of D-shape to mature larvae swarming were 12 to 15 days, and their mean survival rate was from 4.63% to 6.80% in this period.

金東洙,朴炅洋 木浦大學校 沿岸環境硏究所 1996 沿岸環境硏究 Vol.13 No.1

The occurrence and distribution pattern of bivalve larvae, oyster Crassostrea gigas, arkshells Anadara spp., and penshell Atrina pectinata were studied in Deukryang Bay from July 10 to October 18, 1995. The surface water temperature ranged from 20.3 to 30.1℃ with a mean of 23.7℃. The salinity of surface water varied from 32.1 to 35.7‰ with a mean of 33.8‰. A total of 5,377,723 individuals of bivalve larvae was collected during the study period. These were composed of 6.5% of oyster larvae, 20.9% of arkshell larvae, 0.03% of penshell larvae and 72.6% of miscellaneous bivalve species larvae. The D-shaped larvae of oyster were occurred with high density on mid-July and early-August. Whereas the umbo larvae were predominate on mid- and late-July. The full grown larvae of oyster were occurred on late-July and early-August. Thereafter, the number of full grown larvae showed decreasing trend and disappeared after October 5. The D-shaped larvae of arkshell were occurred on mid- and late-July, early- and mid- August. The umbo stage larvae were densely occurred on late-July and early-August, and full grown larvae were late-July and early-August. The mass occurrences of the arkshell larvae were observed five times during the study period, and the larvae were disappeared after October 5. The number of penshell larvae was, however, relatively lower than the oyster and arkshell larvae. D-shaped larvae of the bivlve were occurred mid-July, early- and mid-September, whereas umbo stage and full grown larvae were occurred on late-July, mid-August, early- and mid-September.

Species composition, dominant species and standing biomass of phytoplankton in addition to physico-chemical properties in Mokpo Bay were studied monthly from March to May in 1984. Fifty rhree taxa of phytoplankton reprsenting 26 genera have been identified in this study. They include 44 species, 3 varieties of diatoms and 6 species of dinoflagellaes. Diatoms represented the largest portion of total biomass. In March and April genus Thalassiosira and Melosira have been a dominant group, which were resplaced by Nitzshia in May. In May . In the bottom layer of station 4, Protoperidinium surbinerme represented 66.35% of standing biomass in March. Cell numbers of phytoplankton fluctuated with a range from 11,600 cells/1 to 576,900 cells/1 in the surface layer and 2,300 cells/1 to 1,657,500 cells/1 in the bottom layer during a investigated period.

柳晟圭,朴炅洋 釜山水産大學校 1978 釜山水産大學 硏究報告 Vol.18 No.1

진해만에서 1975년 8월 24일에 채묘한 피조개를 거제만으로 옮겨 1978년 8월 27일까지 약 3개년간 양식한 피조개의 성장결과는 다음과 같다. 1. 양성장의 수온은 최저 6.1℃였고 최고 28.5℃였다. 2. 각장은 만 1년만에 평균 40.03㎜, 만 2년만에 56.25㎜ 및 만 3년만에 78.86㎜로 각각 성장했고, 개체무게는 만 1년만에 평균 22.61g, 2년만에 45.61g 및 3년만에 117.73g으로 각각 증중했다. 3. 각장의 성장도는 수하양식법으로 양성하면 빠르고 수하양성하던 것을 바닥양식법으로 양성하면 처음 일정한 기간 동안은 아주 늦다. 그러나 일정한 기간이 지나면 다시 빨라진다. 4. 개체무게의 증중속도는 만 2년생까지 늦으나, 이 이후부터는 아주 빠르다. 5. 수하양식법으로 양성한 것은 바닥양식법으로 양성한 것에 비해 패각의 무게가 현저하게 무거우나 육질의 무게는 아주 가벼웠다. 6. 수하양식법으로 양성한 것은 바닥양식법으로 양성한 것에 비해 같은 크기의 각장인 경우 개체무게가 현저히 가벼웠다. The results from experiments on the collection and growth of the arkshell(Anadara broughtonii) spats, which were collected in Jinhae Bay and grown in the littoral zone of Geoje both located in the southern area of Korea from August 24, 1975 to August 27, 1978, are as follows: 1. The temperatures of the rearing place ranged from 28.5℃ to 6.1℃. 2. The average shell length attained to 40.03㎜ in a year, 56.25㎜ in two tears and 78.86㎜ in 3 years, and the average weight of a arkshell attained to 22.61g in a year, 45.61g in two tears and 117.73g in 3 years. 3. The arkshell grows faster when reared by hanging culture method than by bottom culture method, and it grows very slowly for a initial period, but after that period it grows fast again. 4. The growth rate of the arkshell was small for the first two years, but after that it became very large. 5. When reared by hanging culture method, the shell-weight became much heavier and the meat-weight much lighter than reared by bottom culture method. 6. When reared by hanging culture method, an individual total weight of the same sized shell length was conspicuously lighter than cultured by bottom method.

宋泰坤,李完玉,朴炅洋 木浦大學校基礎科學硏究所 1988 基礎科學硏究誌 Vol.6 No.-

The freshwater fish fauna was investigated from April, 1987 to August, 1988 in Watan chon, Pulgap chon, Ch'ong chon and Ch'onggye chon of Chol-lanamdo. The collected fish were 6 families, 19 genera, 22 species in Watan chon 9 families, 20 genera, 25 species in Pulgap chon, 7 families, 17 genera, 17 species in Ch'ong chon and 7 families, 13 genera, 15 species in Ch'onggye chon. It was remarkable point in the distributional study of freshwater fishes of Korea that two individuals of Cobitis koreensis were collected in Pulgap chon for the first time and the morphology of them was very similar to the Tongjin River population. This indicated that Pulgap chon was found to be the southern limit of distribution of C. koreensis koreensis. Growth rate and age composition were analyzed by total length of 6 species such as Squalidus gracilis majimae, Abbottina springeri, A. rivularis, Moroco oxycephalus, Cobitis lutheri and Zacco temmincki.
