This paper aims at overviewing Korean fisheries profile with a view on why Korean fisheries need marine ranching program as a new fisheries paradigm - a community-based co-management approach and drawing some policy implications from the advanced experience in fisheries. The aims of community-based co-management approach as a planned approach can be set out under the planning objectives of efficiency and equity. In this context Tongyeong marine ranching program is an important government-sponsored pilot enterprise. Experiences in the advanced fisheries such as Canadian Snow-Crab case suggest that in order to be successful for marine ranching be successful it is necessary that (i) there should be high-value species, (ii) property right should be established, (iii) there should be the reasonable number of participants involved, (iv) the participants and the government should be able to share resource enhancement/management/utilization responsibilities and associated fisheries management expenses. Among these, management cost sharing based on the practical partnership between fishing communities and government is of particular importance because the government must have a full responsibility for all ranching program expenditure unless revenues sufficient to guarantee reasonable income and to share management cost are generated from the ranching business.

This study aimed to estimate the economic value of the recreational fishing in the Jeonnam marine ranching area as a part of the total socioeconomic evaluation of the Jeonnam marine ranching program. A travel cost method was applied to the estimation of economic value of the recreational fishing in the Jeonnam marine ranching area and input variables included annual fishing trip days, average travel cost per trip, average catch amount, monthly income, marriage, age, and personal perception on the marine ranching program. In the analysis, due to its characteristic of count data, both poisson model and negative binomial model were used. Model results indicated that a negative binomial model was statistically more suitable than the poisson model as the overdispersion problem occurred in the poisson model. All signs of the estimated parameters were estimated as previous studies showed. Based on the results, the economic value per trip of the recreational fishing in the Jeonnam marine ranching area was estimated to be 145,000 won and the annual total economic value of the recreational fishing in the Jeonnam marine ranching area was analyzed to be 2,514,000 won. In addition, the change of total value by catch rate showed that the economic value could be increased by 180,900 won as the catch increased by one kilogram.

Multipurpose fisheries base was conceptually designed to establish marine ranching system in the coastal waters around Tongyoung, southern sea of Korea. Fisheries base for marine ranching system has integrated various facilities which were required for the process of spawning, rearing, training, releasing, monitoring and catching functions. This base has five steel piles for supporting upper structure and systems. Four steel piles are surrounded by circular net pen made by steel wire, they have the function of the protection against fouling for pile and scouring for bottom soil as well as secondary rearing and short stocking. We can use the last pile to moor a ship and access to the base. Principal structure with steel piles is designed by optimization technique considering design external forces in the coastal waters of return period of 50 years. Design optimization Problem is formulated for this base. Optimal design of multipurpose fisheries base is numerically investigated by sequential quadratic programming method.

위 내용물 분석을 위하여 경남 통영시 바다목장 해역내 한국해양연구원 가두리 설치 지역에서 2004년 7월부터 8월까지 채집을 실시하였으며, 분석에 사용된 볼락은 점등, 비점등 총 200개체였다. 점등에 의해 유집된 동물플랑크톤중 볼락의 가장 중요한 먹이생물은 요각류(Copepoda), 단각류(Amphipoda)순으로 나타났으며, 비점등구간에서도 역시 요각류(Copepoda), 단각류(Amphipoda)순으로 나타났다. 계절에 따른 먹이조성의 변화를 살펴보면 점등구간의 경우 비점등구간에 비해 비교적 다양한 먹이생물을 고루 섭이하였으며, 특히 점등에 의해 요각류와 단각류의 출현량이 많아 중간육성 기간중 볼락의 위내용물 중 이들이 차지하는 비율이 비교적 높았으며, 비점등구에서는 전조사기간중 요각류의 출현량이 대부분을 차지하였다. 중간육성 기간중 점등, 비점등구간에서 먹이공급 조건에 따른 성장관계를 살펴보면 동일한 조건에서 비점등구에 비해 점등구에서 사육한 볼락의 성장이 양호한 것으로 나타났다.

The harbor siltation by longshore sediment transports has become a serious problem on the East Coast of Korea. A reasonable prediction of the longshore sediment rate is important to approach the siltation problem effectively. In the recently developed 1-line model, the empirical constants of the sediment transport formula, which include the absolute quantity of sediment transport rate and the spatial distribution of breaking wave height by wave deformation, are treated as calibration parameters. Since these constants should be determined by the very long-term shoreline data, the longshore sediment rates are much more reasonable values. The method was applied to Hupo Beach, which has experienced heavy siltation. The authors also discuss long-term shoreline change using aerial photos and the observed wave-induced current patterns. According to the result, the SW-direction sediment transport rate was $146,892m^3/year$, and the NE direction was $2,694,450m^3/year$ at Hupo Beach for the last 11 years. The siltation in Hupo Harbor might be affected by the NE-direction sediment transport from Hupo Beach.

점등 효과에 따른 동물플랑크톤 군집동태의 변화를 관찰하기 위하여 통영 바다목장 해역내 한국해양연구원 가두리 설치 지역에서 2004년 7월부터 2004년 8월까지 채집을 실시하였다. 점등 효과를 알아보기 위한 시료 채집은 야간에 점등구간에서 또한 자연상태의 동물플랑크톤 군집과 비교분석을 위하여 같은 시간에 인접 지역에서 점등에 영향을 받지 않는 장소를 선정하여 점등 시료와 동일한 방법으로 채집하여 비교 분석하였다. 조사기간 중 출현한 동물플랑크톤은 종 수준까지 동정한 21종을 포함하여 총 43개 분류군이었다. 불을 밝힌 점등구에서의 출현 분류군수는 비점등구에 비해 많은 개체수가 나타났으며, 두 구간에서의 동물플랑크톤 평균 출현량에서도 비점등구에 비해 점등구에서 약 $3\sim166$배 높은 출현량을 나타내었다. 본 연구에서 점등(불빛)으로 유집되는 동물플랑크톤 군집의 반응양상은 2개로 대별하여 특정지을 수 있는 것으로 나타났다. "A"그룹은 조사시기별 높은 출현 빈도를 나타낸 종들로 불빛에 명확한 양주광성(photo-positive)종들로 구성됨을 알 수 있었다. "B"그룹에 속하는 종들은 약간의 차이는 있으나, 대부분이 점등(불빛)에 소극적으로 반응하는 음주광성(photo-negative)으로 나타났다.

2004년 9월, 11월 그리고 2005년 3월, 5월, 8월, 11월 총 6회에 걸쳐 제주도 차귀도 연안해역 10개 정점에서 표층 수와 저층수를 채수하여 물리, 화학적 수질특성을 조사하였다. 수온은 $12.2{\sim}28.9^{\circ}C$로 변동폭이 $16^{\circ}C$정도였으며 특히 8월에 저층수온이 $13^{\circ}C$로 저온수가 출현하는 양상을 보였다. 염분은 $30.2{\sim}34.9%o$의 범위였으며 8월에 가장 낮은 염분농도를 보인 것은 육상수의 영향으로 보아진다. 식물플랑크톤의 성장인자인 N/P비는 $5{\sim}76$으로 계절별, 정점별로 다양했다. 그러나 평균적으로 22이상을 보이고 있어 인산인 성분이 식물플랑크톤 성장에 제한인자로 나타나고 있었다. 유기탄소 농도는 TOC가 $92.5{\sim}438.3{\mu}M$의 범위였고 평균은 $217{\mu}M$이었으며 DOC는 $82.5{\sim}299.2{\mu}M$의 범위로 평균은 $130{\mu}M$이었다. DOC/POC비는 60%로 용존유기탄소가 많았다.
