  • A quantitative model was developed in order to estimate fishery production damage due to anthropogenically induced environmental changes. The model is described in the following equation, $Y_D=\frac{{\phi}_D}{{\phi}_G}[Y_0{\cdot}(t_p-t_0)-\frac{Y_0}{{\phi}_G}(1-e^{-{\phi}_G(t_p-t_0)})]$, where, $Y_D$ is annual amount of fishery production by nuclear power plant. ${\varphi}$ D and ${\varphi}$ G are instantaneous decreasing coefficient of fishery production by nuclear power plant and instantaneous decreasing coefficient of gross fishery production, respectively. $Y_0$ is annual mean fishery production without damages. $t_p$ is the present time, and $t_0$ is the starting time of damages. The model was applied to fishing grounds near a nuclear power plant on the east coast of Korea. Since fishery production damages have become bigger with increasing emission of thermal effluents from generators activities in the power plant, this factor has also been considered as, $\delta_{D_i}=\delta_D\({\sum}\limits_{i=0}^{n}\;W_i/W_T\)$, where, $\delta_{Di}$ is the cumulative damage rate in fishery production from generators, $\delta_D$ is the total cumulative damage rate in fishery production, $W_i$ is the emission amount of thermal effluents by generator i, and n is the number of generators in the nuclear power plant. This model can be used to conduct initial estimates of fishery production damages, before more detailed assessments are undertaken.

  • Due to the recent increase in greenhouse gases in atmosphere, world climate is rapidly changing and in turn, the earth ecosystem responds upon the climate changes. Comparing the ecosystem in the past, the present shapes of ecosystem is the result of the serious modification. Fishery resources in marine ecosystem, which usually occupy the upper trophic level, are also inevitable from such changes, because they always react to the natural environmental conditions. The northwestern Pacific is the most productive ocean in the world producing about 30% of world catch. From time to time, however, it has been notified that abundance, distribution and species composition of major fish species were altered by climate events. Furthermore, primary productivity of the ocean is not stable under the changing environments, so that carrying capacity of the ocean varies from one climate regime to another. Major climate events such as global warming, atmospheric circulation pattern, climate regime shift in the North Pacific, and El Nino event in the Pacific tropical waters were introduced in relation to fisheries aspects. The current status and future projection of fishery production was investigated, especially in the North Pacific including Korean waters. This new paradigm, ecosystem response to environmental variability, has become the main theme in marine ecology and fishery science, and the GLOBEC-type researches might provide a solution far cause-effect mechanism as well as prediction capability. Ecosystem management principles for multi-species should be adopted for better understanding and management of ecosystem.

  • This study discusses the development structure of China's Marine Fisheries in the East China Sea. China's marine fisheries have developed since the 1980s along with it's economic expansion. The total catch in the East China Sea has increased especially during the 1990s. The Chinese fishery has developed remarkably through individual management, expansion of their fishing grounds from inshore to off-shore, and increase of the catch in both pelagic and bottom species. In other words, the trawl fishery in China has led to higher production. We can say that the progress in Chinese fisheries is the result of their expansion policy. Their boats have been coming closer and closer to the Japanese and Korea fishing grounds during the 1990s. Chinese fisheries is exploiting the low cost and thus strengthening its quantity. Based on rising fish price, expanding domestic fish markets as well as expels, China is enjoying the high income. However, in trawl fishery, productivity is stagnant and profit is going down due to the rising cost. In accordance with the new 200 mile EEZ system in the East China Sea, China's fisheries will be restricted mostly by the new regulation which requires the reduction of fishing efforts and the application of resource management.

  • Nowadays, Under the current system of fisheries laws, fishery division and marine division are unified into one marine-fishery related law system indiscriminately. So they are not divided by nature. Moreover, terminology of fishery Law has been used by now in inappropriate conditions from Japanese 1951 fishery law systemct. Because fisheries administrative reorganization is also in parallel with the same logic as above, the reorganization of the legal system should be made. Finally, when the above mentioned problems is clearly defined and improvement is actually performed, more efficient management will be achieved through the beneficiary of more simple legal services. And so fisheries managers will be able to contribute to the development of the industries through more efficient management. While the existing framework of laws and regulations currently being enacted or established should be kept as much as possible, in order to ensure better control of fisheries resources and ensure sustainable development of related industries. Under various existing laws including the Fisheries Act, the Enforcement Regulations/enforcement rules, notice, instruction, established rule, the recognition of problems and improvements on the overall delegate legislative framework will be needed.

  • This study investigates the effects of the purpose of fishery firms' social contributions on consumers' purchase intention as a mediator or their fishery firms' brand evaluation. We surveyed 300 consumers in order to empirically test the suggested relationship. The purpose of fishery firms' social contributions was divided into social contribution activities and public interest marketing strategies. Fishery firms' brand evaluation was divided into three aspects including brand awareness, brand image, and brand loyalty. The results showed that the purpose of fishery firms' social contributions significantly affect consumers' purchase intention, brand loyalty as well as brand image except brand awareness. Fishery firms' brand evaluation significantly affect consumers' purchase intention. This study suggests that social contribution activities and public interest marketing strategies are essential for the positive brand evaluation of fishery firms.

  • Under the circumstances of China's slower economic growth, the first document ofthe central committee of the CPC continue to focus on "three agricultures" problems, agriculture play a basic role on China's economic. Since 2007, the first document directly stresses the important role of agricultural and fisheries every year. Central Government Working Report of 2015 also stresses that under the new normal of economy, it is important to improve quality and efficiency of agriculture. Agricultural focus going forward will be on improving capacity of competitiveness, innovation and sustainable development.The fishery as an important part of agriculture plays a vital role in the protection of national food security, the prosperity of the rural economy and the optimization of national food structure. However, the situation faced on accelerating the speed of Chinese fisheries is still grim. As an important fishery breeding city in my country, Weihai has achieved remarkable results in the development of fisheries. Based on the input-output indicators of Weihai City from 2010 to 2020, this article uses the DEA model method to conduct a comprehensive analysis of the factors affecting the fishery production efficiency in Weihai City. This paper calculates the two stages of comprehensive efficiency, pure technical efficiency and scale efficiency, and comprehensive compares the two stages. The research results show that: From 2010 to 2020, the average comprehensive technical efficiency of Weihai fishery was 0.928, the average scale efficiency was 0.963, and the average pure technical efficiency was 0.963. The comprehensive technical efficiency of Weihai fishery production showed an upward and downward trend, the pure technical efficiency showed a downward and then upward trend, and the pure technical efficiency showed a fluctuating trend.

  • This study is to contribute to income growth of fishermen by the common octopus fishery characterized in the Tando Bay on the southwest coast of Korea. This area is engaged in Longline fishing (301 persons), Shovel fishing (196 persons), Trap fishing (14 persons) and Torch light fishing (40 persons) in 2008. Population who is joined in the spring becomes main fishery target population of longline fishery in the fall because entering fishing ground in August, and is joined in the fall becomes main fishery target population of longline fishery in the spring because entering fishing ground in December. Average size of common octopus examined by longline 6.26cm, 5.82cm for Shovel fishing, 8.09cm for trap, and expressed big difference by fishery. It needs necessary various kinds of Octopus resource management actions and methods in continuous use. Specially, Fishing force increased by fishing automation system, so the reduction of fishing force is needed to increased by fishing force. Government support and fishermen's self-conscious of resource management is needed.

  • There exists historically intimate relationship between the fisheries of the three countries of Northeast Asia in terms of the same fishing ground and similar resources. This means that if one of the countries fail to manage their fisheries properly, it will harm the others. Especially, if the EEZ straddling and Trans-Boundary Fish Stocks aren't managed by the cooperation of the three countries, the exhaustion of resources will be more likely to be accelerated. Considering the aspects mentioned, this paper refers to the necessity of fisheries cooperation between Korea, China, and Japan. Next, it analyzed the joint control cases of Norway/Russia Management of Shared Fish Stocks in the Barents Sea, Management of South Tasman Rise in Orange roughy, Agreement on Fisheries between the European Economic Community and the Kingdom of Norway, Conservation and management of pollack resources in the central Bering Sea, and drew a conclusion for ourselves. Last of all, it suggests a step-by-step strategy of promoting joint control between three countries, and the plan of the establishing and managing the organization of joint fisheries control. About the joint control, "The Joint Statement of promoting collaboration between Korea, China, and Japan" has been announced at ASEAN in October 7th, 2003 and the summit talk of the three countries. In the joint statement, the three countries came to an agreement which says, "Cooperation in Fishery Resource Conservation : The three countries will cooperate, bilaterally or trilaterally, to promote the sustainable use and conservation of fishery resource through the effective fishery management". Not only the consistent collaboration between the government is necessary, but also continuous exchange and related study on a Non-governmental level is also needed for the viable outcome in the near future. When deducting the result for the joint fisheries control, this writer hopes the contents of this study will be helpful.

  • In case of the Sea Areas Utilization Consultation about fishery harbor facilities there has been problems excepting a mooring facility and having the same scope of business subject with harbor, while those scale are different. In this study, we analyzed the 17 cases of the statements for Sea Areas Utilization Consultation according to the development projects of fishery harbors for 2013-2014 and suggested the improvement way to go. First, it is needed to reassess the scope of business subject about fishery harbor because the environmental effects about the development projects for the fishery harbor are not considered separately by facilities, development project for the fishery harbor. Therefore, the reassessment about them are needed surely. Second, the adjustment of the range about fishery harbor facilities on the Sea Area Utilization Consultation is needed because in case of most small fishery ports, the sizes of those facilities are less than the boundary area ($50,000m^2$). Last, consultation subjects shall be more clear in order to protect confusions-related with applying for the Consultation on Utilization of Sea Areas. A new rule for clarifying consultation on business subjects is needed in order to reduce the unclarity and the confusions from being occurred by difference between 'occupancy or use permit of public waters' and 'exclusion of application' and business subjects according to the Public Waters Management and Reclamation Act and the Marine Environment Management Act, respectively.

  • The permit system is the most typical regulation system in Korean fishery. Even now, it has caused resource management failure, it has also invited economic inefficiency and inequity. Accordingly, the Korean government has recently introduced the fishing boats market, it would be improve entry barrier for new capital and labor in fishing industry. This study aims to survey and to analyze the status of coastal fishing boat market using the executive documents on permit system in Gyongnam province. And also, this study put focus on improve fishing permit trade take advantage of the fishing boat trading. The survey results indicated that the number of fishing boats trading is estimated about 5,000 per year, however, fishing boat market is very narrow. An analysis on fishing permit trading showed that policy support is essential to reduce transaction cost. Therefore, it is necessary to explore corresponding policy tasks, this will be reduce transaction costs and sunk cost.
