  • 색소 추출물의 급이에 의한 무지개송어 간지질의 지방산조성 변화를 조사한 결과는 다음과 같다. 1. 색소 추출물의 지방산조성은 18:2n-6가 $14.2\%$, 20:5n-3가 $3.5\%$, 22:6n-3가 $8.3\%$로 EFA 사료로서의 가치가 인정되었다. 2. 모노엔산의 함량은 급이 중 변화가 컸으며 이는 고도불포화산의 변화에 기인된 것으로 나타났다. 3. 색소 추출물 급이에 의해 2주 후 무지개송어의 고도불포화지방산의 함량이 증가하여 $25.9\%$$23.1\%$로 나타났으나, 대조구 및 pink구에서는 $15.0\%$$18.8\%$로 각각 나타났다. 4. 20:4n-6의 함량이 대조구나 pink구에 비하여 높게 나타나 EFA 결핍에 의한 변화는 없는 것으로 나타났다. 20:1n-11 및 20:2n-11의 함량이 낮은 것은 급이사료에 의해 영향을 받는 것으로 나타났다.

  • Morphological changes in the reared rock bream, Oplegnathus fasciatus, from hatching to six days after hatching were examined during the early growth stage under starvation. All the larvae died within five days when feeding was delayed for three days after hatching. These results imply that initial larval food should be supplied within two days of hatching. Changes in the pectoral angle and the ratios of eye height to head height, gut height to standard length, and gut height to myotome height in the rock bream are alternative indicators for the identification of starving fish. These indicators might prove useful in evaluating the successful transition from endogenous to exogenous feeding in this species.

  • The authors investigated the present status of employment of graduates from ship-boarding departments, Department of Fishing Technology, of Marine Engineering in National Fisheries University of Pusan from 1974 to 1988 by communication of every kind. The prospects of the graduates were studied on the bases of the present status of employment The results obtained can be shown as follows ; 1. In Department of Fishing Technology, the number of graduates who are engaged in major field is 562 (81%) among total members of graduates 693, and fishing vessel officer and fisheries company officer is 308(55%), 215(38%) respectively among the above members of employment in major field. 2. In Department of Marine Engineering, the number of graduates who are engaged in major field is 468(74%) among total members of graduates, 634, and engine and machinery field officer, merchant vessel officer is 331(71%), 89(19%) among above members of employment in major field respectively. 3. Developement of deep sea fisheries and industry of engine and machinery seems to graduates easy to get their jobs in major field.

  • The authors analyzed the daily catch data which were obtained from two different regions at the Southern Sea in Korea, Neungpo, Geoje island and Yangwhagum, Namhae island, during three or four years in 1978, 1981-1985, in order to know the fishing characteristics of the set net fisheries. The favorable fishing season was summer in the southern sea. The total catches during one year were greatly affected by those several day when the dominant species of fish were caught in large quantities. The dominant species of fish at Neungpo were little horse mackerel, sand lance, sardine, hair tail, spanish mackerel and common mackerel, and those at Yangwhagun were anchovy, little horse mackerel, sardine, spanish mackerel and gizzard shad, in order of catch. Especially, the little horse mackerel and the sardine appeared to make up very big schools at both Neungpo and Yangwhagum. The occurrence seasons of the dominant species were different by the region, but generally those were earlier at western part than at eastern part of the Southern Sea in Korea.

  • The creation of marine protected areas is an important aspect of marine ecosystem sustainability. However, South Korea has not achieved its Aichi Biodiversity Target to designate 10% of its sea as marine protected by 2020. Local residents have strong opposition to the designation of protected areas in South Korea; there has been little trust in the government since the 1970s, when residents felt that their property rights were being ignored in favor of creating national parks. Here, we present a case where creation of a marine protected area was led by residents of TongYeong City. The success of a participation income project to remove marine debris in the city seems to be an important factor that led to the designation of the marine protected area. The case of TongYeong City is compared with that of nearby Geoje City, where an ecologically important stream has not been designated as a wetland protection area, although a similar participation income project enrolled the city's residents. The comparison provides a tentative assessment of the conditions needed to increase trust among residents. The results suggest that, if the projects are well-designed and well-managed, participation income projects to remove marine debris can be effective in building trust among stakeholders in potential marine protected areas.
