  • 낚시터로 장기 임대중인 농업용 저수지 2곳을 대상으로 낚시터 영향권(effective zone) 2지점의 퇴적물과 비영향권(ineffective zone) 1지점의 퇴적물을 호기(oxic)와 무산소(anoxic) 조건을 조성한 실험실 코어배양법(laboratory core incubation)을 이용해 영양염류 용출시험을 2회씩 실시하였다. 용출 실험동안 상등수 내 DO, EC, pH, ORP의 변화는 낚시터 영향구간과 비영향 구간 사이에 유의할만한 차이는 관측되지 않았으며(p>0.05), 농업용 저수지의 퇴적물-심층수 확산경계면과 유사한 환경으로 조성되었다. 질산성 질소($NO_3{^-}-N$)를 제외하고 암모니아성 질소($NH_4{^+}-N$), 총인(T-P), 인산염 인($PO{_4}^{3-}-P$)이 호기 보다는 무산조 조건에서 통계학적으로 유의한 수준(p<0.05)으로 퇴적물에서 상등수로 더 많은 용출량이 측정되었다. 이는 상등수 내 DO 농도 감소에 따라 미생물 매개의 암모늄화가 촉진되고 질산화 작용이 억제되어 암모니아성 질소가 퇴적물에서 상등수로 확산 용출되고, 퇴적물 표층의 산화층이 환원되어 유기물에 결합된 인과 금속 산화물과 결합된 인의 해리 등을 통해 인산염인이 퇴적물에서 상등수로 확산용출이 가속화되었기 때문이다. 낚시터 영향권과 비영향권 사이 영양염류 용출량(benthic nutrient diffusive flux)값의 차이는 통계학적으로 유의하지 않았다(p>0.05). 따라서 농업용 저수지 내 낚시활동이 퇴적물의 영양염류 용출량을 통계학적으로 유의한 수준으로 증대시키지 않는 것으로 조사되었다. 이러한 결과는 농업용 저수지 설립년도 대비 10여년의 단기간 낚시활동으로 인해 퇴적물 오염 기여도가 비교적 낮고, 코어배양법의 속도제한된 확산(rate-limited diffusion)으로 발생한 것으로 판단된다. 호기와 무산소 조건 모두에서 퇴적물 내 영양염류 총량과 영양염류 용출량 사이에 유의적 상관관계가 도출되지 않았다. 따라서 농업용 저수지 수질오염의 가속화가 낚시활동으로 인한 직접적 원인보다는 유역에서 유입되는 다양한 비점오염원 내 영양염류가 주요 요인으로 판단되며, 영양염류의 용출을 저감하기 위해 포기 및 물순환 등을 통해 심층수의 빈산소화를 억제할 필요가 있다.

  • This study is aimed at the deduction of the important priority factors by setting the comprehensive rate in each of the economy, sociability and environmental areas for the sustainable development of fishing villages. As the research methods, review of domestic and overseas literature and Delphi questionnaire survey on experts, and hierarchical structure analysis were executed. Accordingly, this study is aimed at providing the basic data at the time of establishing plans by assessing the level of importance and priorities for each item through the deduction of the elements necessary for the fishing village plan. Key results of the study are as follows. First, as the results of review of domestic and overseas literature related to sustainability indices of fishing villages, a total of 50 items in the areas of economy, sociability and environment were deduced. Second, validity for each area was confirmed through Delphi questionnaire survey on experts. Third, as the results of factor analysis conducted on the basis of the hierarchical structure analysis for detailed items for each sector, 3 factors in the economic area, 2 factors in the social area and 3 factors in environment area were deduced. Fourth, as the results of the relative importance of the higher tiers, economic sector (0.528) displayed results that are more than 2 times higher than the social (0.261) and environmental (0.212) sectors. Establishment of foundation for independent competition (0.105), balanced development of small fishing village (0.086) and population engaged in economic activities in comparison to the fishing village population (0.077) were analyzed as the most important detailed items. Based on these results, experts pointed out that the economic sector is most important for the sustainable development of fishing village and, in detail, priority must be placed on the balanced development on the basis if the extent of independence of the fishing villages, and emphasized activation of residents engaged in economic activities in fishing villages in order to support them. That is, in order to increase the level of independence of the fishing villages, it was determined that there is a dire needs for expansion of diversified specialized businesses and infrastructural facilities through agreement by the residents capable of economic activities, and means of activating fishing villages through securing of budget at the local autonomous government level to provide support for the residents.

  • Korean fisheries industry is surrounding by domestic and international difficulties due to the effectuation of the UN Convention on the Law of the Sea and declaration by many coastal states of 200-mile Exclusive Economic Zone and acceleration of ocean pollution in global recognition increasing of the importance of the ocean Resource enhancement policy in Korea fisheries industry is very important strategy fer the fostering of the fisheries resource and proper conservation and management of the coastal and off-shore living marine. Among resource enhancement policy, artificial reefs project has been the most effective strategy. The objectives of this paper are to find the economic effects of artificial reefs. The sampling artificial reefs is constructed at Suiido with 6~7m height. In order to analyze the fishing effect of artificial reefs, a few research have been conducted since 1975. For these analysis focuses on the side of scientific effect of artificial reefs, we analyzed on the side of economic effect. The results of the economic effects of artificial reefs are as follows ; First, the fishing effect analysis by using the NPV method in artificial reefs of Suiido ground prove to be economic feasibility. Second, the major socio-economic effect from artificial reefs include the increasing of recreation fishing, maintenance of fishing community, protection illegal fishing, conservation of coastal environment, and enlargement of advanced fisheries supply. Based on the above results, we conclude that artificial reefs project not only contributes to the welfare of fishermen by increasing of economic income, but enlarges to socio-economic gains by protection of illegal fishing and conservation coastal environment and so on.

  • The FAO reports that IUU fishing activities have widespread economic, social, and management consequences, including depriving legitimate fishers of harvest opportunities. It affects all fisheries from small scale to industrial. It also affects the ability of governments to support sustainable livelihoods for fishers and, more broadly, to achieve food security. The complexity of IUU requires various measures to combat IUU fishing such as adoption of IUU vessel lists; stronger port State controls; improved monitoring, control and surveillance (MCS); implementation of market-related measures to help ensure compliance; and capacity-building assistance. Trade and market measures reduce opportunities for IUU fishing activities by precluding or impeding access to markets for IUU product in a manner consistent with international law. ICCAT, CCAMLR, and IATTC, have put in place trade tracking programs or catch documentation schemes, and WCPFC is considering such a program. Vessel lists assist enforcement authorities in determining which vessels are or are not authorized to be fishing or conducting fishing support activities in specified areas. A number of RFMOs maintain records of IUU vessels: CCAMLR, IATTC, ICCAT, NAFO, NASCO, NPAFC, WCPFC. Section 608 of the US MSRA calling on the Secretary of Commerce, in consultation with the Secretary of State, and in cooperation with relevant regional fishery management councils and any relevant advisory committees, to take actions to improve the effectiveness of international fishery management organizations in conserving and managing stocks under their jurisdiction. EU IUU Regulation entered into force on 1 January 2010, was intended to regulate the highly complex multi-channel fisheries supply system of the European Community (EC) in an effort to improve global fisheries sustainability.

  • Today, all the countries of the world newly recognize importance of sea on 70% area of the earth, which are focused on efforts for security of marine territory and fishes resources. On the security concerns of the ocean & fishes resources, Sea are very important on the ground of the importance of the ocean, thus international community has been trying to combat a maritime security threat and illegal fisheries. Coastal states need to have proper state's jurisdiction and exercise it's jurisdiction to response effectively to a maritime security threat and illegal fisheries. Here, many of the coastal states strengthened the rights in Exclusive Economic Zone(;EEZ) naturally, there are made cooperation activities and keen competition in the sea because deepening of complex understanding of the relationship between the surrounding countries with marine surveys & continental shelf development, island territorial sovereignty & marine jurisdiction in overlap of sea area on EEZ. In these circumstances, foreign fishing boats invaded to our territorial waters and EEZ many times. in addition, Chinese fishing boats are going to illegal fisheries naturally. On this point, a powerful crackdown of maritime enforcement organization had no effect on them. Also more and more their resistance gathered strength and tendency of a illegal activities became systematization, group action and atrocity little by little. So this thesis includes a study on the regal regulation, the system and formalities on the control of illegal fishing. And the author analyzed the details of the activities of illegal fishing and boats controlled by Korea Coast Guard(KCG), fishing patrol vessels of Ministry of Maritime Affaires and Fisheries(MOMAF) and Navy etc. from in adjacent sea area of Korea. In relation to this, the policy and activity plan were devised to crackdown to illegal fisheries of foreign fishing boats and then it was enforced every year. According to this, analyze the present conditions of illegal fisheries of a foreign fishing boats on this study, also analyze the present conditions of maritime enforcement organization & found out problems to compared it. protect the territorial waters, at the same time protection of marine mineral resources & fishes resources of EEZ including continental shelf, which has want to study for the role & response of maritime enforcement organization for the protection of fisheries resources and a proper, a realistic confrontation plan of maritime enforcement organization against illegal fisheries of foreign fishing boats.

  • 1994년 유엔해양법 발효 이후 해양활동의 무대가 배타적 경제수역과 대륙붕까지 확대됨에 따라 각국은 자국의 권리를 강화해 나가고 있으며 국제사회는 국익을 확보하려는 다툼이 더욱 치열해지고 있다. 이와 관련하여 해양주권에 대한 연구가 많이 이루어졌으나 정책적인 연구에만 국한 되었을 뿐 실증적인 연구는 전무한 실정이다. 따라서 본 연구에서는 해양주권에 대한 실증적 인구를 위해 최근 빈번히 발생하고 있는 중국어선이 불법조업 사례를 대상으로 연구를 실시하였다. 해양주권 침해의 요인이 되는 요소를 선정하여 상관분석과 다중 회귀분석을 실시하였으며 또한 해양주권 침해의 경제적 파급영향을 분석하였다. 분석결과, 중국의 수산물 증가로 인해 발생한 중국 불법조업의 중가는 우리나라의 수산물 생산량을 감소시켰으며 이는 우리나라 어가 경제에 손실을 미쳤을 뿐만 아니라 우리나라 가계 경제에도 큰 부담을 초래 하였다.

  • Although the General Agricultural Fishing Village Development Project had a significant impact on the landscape formation and management in rural area, the rural landscape planning and project sectors was not stable by fluctuation variables. On the basic understanding the institutional status of rural landscape planning, some conclusions could be discussed as follows through the analysis of quantitative and qualitative changes and the background factors. The rural landscape plan lacked its own legal and institutional foundations, and the landscape project of the General Agricultural Fishing Village Development Project was mainly focused on the environment-improving H/W project for expanding the basic living infrastructures. In order to reflect the characteristics of the region and become independent rural landscape management, it is necessary to change the contents so that the S/W business such as the deepening landscape awareness and empowerment linked with improving the physical landscape. To this end, it is necessary to establish a foundation for the rural landscape planning system to have its own status, and it seems to seek to supplement with what is included S/W contents reflecting the context of higher level landscape planning. The landscape sector of the General Agricultural Fishing Village Development Project proved to be in the process of shrinking in both quantity and quality, despite the temporary expansion in the past. In addition, considering the distortion of the contents of landscape projects in rural sites, it seems that the rural landscape-related public project are now in a position to seek a new phase change beyond quantitative expansion. In particular, along with institutional improvements to secure the independent status of rural landscape planning that contributes to village community regeneration and social sustainability through the role of intermediary support organizations in landscape management activities. Through the integrated landscape plan, which is established in advance and led by the residents in the early stages, there is a need to change the direction to enhance meaning of the landscape planning goes beyond the facility design or space improvement.
