Korea's marine products trade is taking for phase that income exceeds export after 2000. According to external environment change of Korea and Japan fishery agreement and an import liberalization of marine products, import of live fish and fresh fish is increasing rapidly. This study investigates import view of Japan live fish and fresh fish. Live fish which is imported from Japan has red seabream and seabass, but it is in declining tendency because of the increase in import of cheaper croaker from the China. If see importer's trend, entry to import business of fresh fish is eased a little. If a circulation trend is seen, However, it is thought that a future import trend is influenced by economic trends of Japan and the grade of place-of-production development of a domestic trader. Circulation market outside is common and the district wholesale store has played the important role. The import view of Japanese live fish and a fresh fish will increase against the background of maintenance of domestic circulation organization, and upgrading of marine product consumption However, it is thought that a future import trend is influenced by economic trends of Japan and the grade of place-of-production development of a domestic trader.

The main purpose of this study is to analyze the cooperative squid fisheries problems surrounding the $E128^{\circ}$, established by the 1965 Korea - Japan Fisheries Agreement which banned Korean large trawlers' fishing east to the $E128^{\circ}$ In fact, the moratorium was put on by Japans request. However, such issue did not occur until the filefish stock in the southern Korean sea, which was a major target fish species of the large trawl fisheries, The filefish stock collapsed completely around 1991 and at the same time most of bottom fish stocks in the East China Sea began to show a symptom of over - exploitation. Thus, the off - shore large trawlers learned to have a little opportunity of finding out alternative fish stocks as well as fishing grounds. Fortunately, at that time squid resource stock and consumption were on the increasing trend. The large trawl fisheries were able to economically exploit squid stock east to the $E128^{\circ}$ through cooperative fishing with squid angling light boats in the East and East - South Sea, even though such cooperative fishing activities violate the existing fishery laws apparently. Some important reasons that the large trawlers have continued the cooperative fishing seem to be because (ⅰ) squid resource stock has been on the increasing state over time, (ⅱ) the trawl fisheries have made a significant contribution to meeting domestic and export demands and stabilizing squid prices, and (ⅲ) they have kept domestic squid market from foreign competition. However, the new Korea - Japan fisheries agreement in 1998 provided a momentum of questioning the effectiveness of the $E128^{\circ}$ by the squid - related fisheries other than the squid angling. Serious conflicts between squid - related fisheries began to emerge and to be much intensified. Squid angling industries in the East opposed to large trawlers's efforts to formalize such illegal cooperative squid fishing activities. Their main argument was that such formalizing would definitely make the East coast squid prices lower and in turn their business performance would be worse off. The results of quantitative analysis suggest that the trawlers' massive landing may have a significant influence on lowering the east coast squid prices. Now, an important issue that the squid - related fisheries and the government are facing is to solve such complex squid fishing problems through a multi - participatory negotiation process, including price stabilization, total allowable catch level and its operation schemes, $E128^{\circ}$ rearrangement, and so on.

최근 친환경항만(Eco-port)을 건설하려는 노력과 쾌적한 워터프론트 개발에 관한 관심이 고조되면서, 항만의 방파제를 중심으로 수질개선을 위한 다양한 연구가 진행되고 있다. 이러한 항 내의 수질개선을 위한 연구로서 최근 해수교환방파제가 주목받고 있지만, 여전히 항 내 안쪽의 영역에서는 해수교환방파제로부터 유입된 해수가 도달하지 못하여 해수의 순환이 잘 안 되는 단점을 가지고 있다. 본 연구에서는 이러한 해수교환방파제의 단점을 보완하고자, 다기수로라는 새로운 개념의 해수교환방파제를 도입하여, 항 내 안쪽 영역까지 해수의 순환을 촉진할 수 있는 방법을 모색하였다. 이를 위해서 현재 해수교환방파제가 설치된 주문진 항에 가상의 다기수로를 설치하고, 수중유출구의 위치, 크기, 방향을 제어하여 해수유입에 따른 항 내 유동패턴을 비교 검토하고, 해수순환을 촉진시킬 수 있는 방법을 모색하였다.

This article's aim is to review the jurisprudence which has emerged pursuant to the international dispute settlement provisions and to provide a provisional expectation as to the future of international dispute settlement under "UNCLOS". Globally, marine fisheries play an important role in ocean biodiversity and the food security of millions of people, providing a vital source of high-quality dietary protein and supporting individuals' livelihoods and income. In the 1982 Convention, the establishment of co-operative mechanisms for effective monitoring, control, surveillance and enforcement, decision-making procedures facilitating the adoption of such measures of conservation and management, and the promotion of the peaceful settlement of disputes are called for. In this study, 'Northeast Asian Sea' means that the Yellow/East China Sea, the East Sea, the Ohotsk Sea, the Kamchaka Sea, the Alaska Sea, and the Bering Sea surrounded by Korea, China, Japan, Russia, U.S.A. and Canada including their EEZs. There are several bilateral fisheries agreements existing in Northeast Asian area, the Fisheries Agreement between Republic Korea and Japan, between Republic of Korea and China, between China and Japan, between Republic Korea and U.S.A., between Republic Korea and Russia, between Russia and Japan, And there are several regional fisheries organizations existing in Northeast Asian area, for example NPAFC(Convention for the Conservation of Anadromous Stocks in the North Pacific Ocean), CBSPC (Convention on the Central Bering Sea Pollack Conservation), PICES(North Pacific Marine Science Organization), NPFC(North Pacific Fishery Commi-ssion) etc. It analyzed the proliferation of bilateral treaties and multilateral treaties due to the adoption of the EEZ in Northeast Asia reviewed the strengthening of management rights on the high seas marine living resources and marine environment preservation of regional fisheries organizations. In view of the changes in the international fisheries mechanism this paper suggested the future direction of the country in overseas fisheries. We concluded as follows. We shall apply bilateral treaties first, regional fisheries organizations' treaties secondly, and provisions under "UNCLOS" for dispute settlement last.

This paper attempts to extend such analysis to the rather more difficult problem of optimal management of transnational fish stocks jointly owned by two countries. Transboundary fish such as Mackerel creates an incentive to harvest fish before a competitor does and leads to over-exploitation. This tendency is especially poignant for transnational stocks since, in the absence of an enforceable, international agreement, there is little or no reason for either government or the fishing industry to promote resource conservation and economic efficiency. In the current paper I examine a game theoretic setting in which cooperative management can provide more benefits than noncooperative management. A dynamic model of Mackerel fishery is combined with Nash's theory of two countries cooperative games. A characteristic function game approach is applied to describe the sharing of the surplus benefits from cooperation and noncooperation. A bioeconomic model was used to compare the economic yield of the optimal strategies for two countries, under joint maximization of net benefits in joint ocean. The results suggest as follows. First, the threat points represent the net benefits for two countries in absence of cooperation. The net benefits to Korea and China in threat points are 2,000 billion won(${\pi}^0_{KO}$) and 1,130 billion won(${\pi}^0_{CH}$). Total benefits are 3,130 billion won. Second, if two countries cooperate one with another, they reach the solution payoffs such as Pareto efficient. The net benefits to Korea and China in Pareto efficient are 2,785 billion won(${\pi}^0_{KO}$) and 1,605 billion won(${\pi}^0_{CH}$) or total benefits of 4,390 billion won : a gain of 1,260 billion won. Third, the different price effects under the two scenarios show that total benefit rise as price increases.

The fishing grounds of Korean large-pair trawlers have shifted since exclusive economic zones (EEZs) were established in a fisheries agreement involving countries neighboring Korean waters. The distributions of marine ecosystems and fisheries resources have been changing with environmental changes such as global warming and with the shift in species targeted as a result of changes in fishing technology and fishing gear. This study analyzed variation in the species assemblages caught in Korean waters by large-pair trawlers as a result of these geopolitical and environmental changes. The data used in this study were obtained from the Fishery Production Statistics of Korea and the Port Sample Survey of the National Fisheries Research and Development Institute (NFRDI) from 1990 to 2007. Hierarchical clustering analysis (HCA) and correspondence analysis (CA) were used to explore the characteristics of the catch-species composition. The overall variation in the species composition of the catch of Korean large-pair trawlers showed that the proportions of croaker Johnius grypotus, small yellow croaker Larimichthys polyactis, eel Anguilla japonica, and blue crab Portunus trituberculatus decreased, whereas those of hairtail Trichiurus lepturus, Spanish mackerel Scomberomorus niphonius, anchovy Engraulis japonicus, and common squid Todarodes pacificus increased in Korean waters over the 18-year period. The results of the HCA of the annual catch data by species showed four different distributions of fish species according to year. Results of the CA showed that the species assemblages differed between the 1990s and 2000s.

In this study, a series of laboratory experiments were carried out to investigate the weak reflection of regular and random water waves over a train of protruded permeable shore structures. A cylindrical slit type breakwater and the alternatives are employed and compared for reflecting and transmitting capabilities of incident waves including wave forces. A series of random waves were generated by using the Bretschneider-Mitsuyasu frequency and directional spectrum. Measured spectrum of irregular waves without breakwaters is verified by comparing with those of the input waves generated. Weak reflection is occurred at the breakwater center of the peak frequency. If the row of breakwaters is fixed at three layers and the relative height of breakwater is fixed at 0.6, around 45% of incident wave energy is reflected to offshore. It is also found that the transmission of directional random waves increases as the maximum frequency parameter increases. A very good agreement is observed. Reflection coefficients of permeable submerged breakwaters are less than those of impermeable breakwaters. The upside-down L shape is recommended for a small fishery harbor mooring in terms of reflecting capability and of practical application. The final design was applied to the wharf of a small beach of Seolly, near Namhae at the southeast coast of Korea.

남강댐 하류는 부산 경남의 수자원 장기 계획에 중요한 지역이므로 지속가능한 지표수 관리 및 오염원 제어를 위해 흐름 및 수질 해석이 필요하다. 따라서 본 연구에서는 2차원 수질모형인 RAM4와 3차원 수질모형인 WASP을 각각 수리모형인 RAM2 및 EFDC모형과 연계하여 2 3차원 준연계 모형을 이용한 남강댐 하류에서의 수리 및 수질을 해석하였다. 2차원 흐름해석 모형인 RAM2 적용 결과 만곡부 5개 횡단 측선에서의 유속의 증감경향이 ADCP 실측값과 잘 일치하였으며, 3차원 모형인 EFDC와 유속 분포 및 보 월류 유속이 유사하였다. 또한 정상상태 도달 후의 RAM2-RAM4 연계모의에 의한 BOD 농도와 EFDC-WASP 연계모의에 의한 BOD 농도장이 모의영역 전반에 걸쳐 유사하게 나타났다. 남강댐 하류부의 경우 수리 및 수질이 남강댐 방류량에 크게 좌우되며 남강댐의 수량은 하류부의 수질 및 연안 어업환경에 큰 영향을 미치므로 향후 이에 대한 정량적 분석 시 계산의 효율성 및 모형의 적용성 측면에서 2차원 준연계 모형을 적용하는 것이 바람직한 것으로 판단된다.
