  • In the design of high speed fishing vessel, its hull form has to be decided from a view point of resistance and propulsion performance without negelction of seakeeping characteristics. In spite of many efforts, the performance improvement by hull form itself has its limitations, specially for high speed craft. In this paper, the development of performance of resistance and seakeeping improving appendage for high speed planing hull on behalft of the hull form of fishing vessel has been introduced. The developed appendage verified its effectiveness in the full scale test.

  • In response to the global interest and efforts towards reducing plastic use and promoting resource recycling, there is a growing need to establish methods for recycling discarded fishing gear. In Korea, various technologies are being developed to recycle discarded fishing gear, but significant technical and policy challenges still remain. In particular, biodegradable gill nets require a pre-treatment process to separate biodegradable materials from other substances and to remove salt before recycling. Therefore, this study aims to develop a pre-treatment device for recycling biodegradable gill nets and to evaluate the feasibility of recycling them.

  • This study is to focus on the status of implementation of bilateral-fishery order based on the Korea-China fisheries agreement and aims to improve fisheries relationship between two countries. Korea-China Fisheries Agreement entered into force in 2001, and serves as a basic framework of the bilateral fisheries order. However, the fishing order between Korea and China has the following limitations. First, it is standstill of joint response for a practical resource management. Second, there are still gaps between the quotas of mutual accord fishing and fishing operation work performance. Third, China's illegal fishing is taking place consistently. Fourth, the effective cooperation between two countries in fisheries is not carried out. Finally, the Korea has faced difficult situations to adhere to a balanced position in the fishery negotiations due to conflicting positions on China and Japan. In order to solve these problems, the fishing order between Korea and China will be able to maintain the competitiveness of Korean fishery sector by reinforcing Korea's fishing sovereignty, Korea and China, based on trust and cooperation, will make efforts to improve bilateral fisheries relations to maximize mutual benefit in fishery sector. Specifically, first, the two countries should strengthen the resources management based on the scientific research and the improvement of imbalance of the mutual agreed fishing in EEZ. Second, Korea has to achieve our targeted performance of fishing operation and establish a joint resources management system between two countries in the provisional measure zone. Third, Korea should implement to collect fisheries information about China fishing vessels which are operating in the EEZ of Korea. Finally, Korea and China should be building up effective governance framework for the establishment of fishing order.

  • 우리 배타적 경제수역에서는 불법조업과 폭력행위 등을 반복하는 중국어선을 단속하기 위한 우리 정부의 계속적인 노력에도 불구하고 배타적 경제수역에서의 불법조업행위는 멈추지 않고 오히려 단속 해양경찰의 피해가 속출하고 있다. 한편, 범정부적인 노력에도 불구하고 해양경찰의 불법외국조업선에 대한 단속 과정에서 여러 문제점이 노출되고 있다. 해양에서 외국선박에 대한 단속은 한편으로는 정당한 사법절차의 진행으로 당연한 국가의 권한이지만, 이러한 집행이 적절하지 못하게 이루어질 경우 국제적 분쟁이 발생할 가능성도 존재한다. 따라서 본 논문은 관련 자료, 전문가의 견해 및 최근 사건 등을 바탕으로 우리나라 관할수역에서 발생하는 불법조업 중국어선에 대한 검문 검색이나 사법절차의 진행 등 단속과정 진행 중 제기되는 문제점을 분석하고 이에 대한 해결방안을 제시하고자 한다.

  • Today, all the countries of the world newly recognize importance of sea, which are focused on efforts for security of marine territory and fishes resources. Many of the coastal state, to strengthen the rights of their own country EEZ, marine survey and continental shelf development, travels through such maritime jurisdiction in the territorial sovereignty and the EEZ overlaps, deepening complex interests between neighboring countries cooperation activities of the fierce competition, the domestic and foreign been has been carried out. Under such circumstances, is devastated coastal of China, our territorial waters and EEZ has been violated more and more, in spite of the powerful crackdown maritime public power, illegal fishing more resistance intensified. They tend to be gradually organization, collectivization and atrocities. Currently, illegal fishing of Chinese fishing boats in the West Sea of Korea, including the waters near Yeonpyeong Island is prevalent as operating in the coast of the country. Furthermore regrettable one is illegal on a scale and the situation where South Korea of scale of damage caused by it have not been accurately grasp of the operation, but that there is damage of Korea official duty enforcement to crack down the increase to illegal operations year after year have occurred. Violent, illegal fishing of Chinese fishing boats, in order to eradicate the operations of insane at our sea, we investigated to the infringement situations of fisheries resources by multiple fields. each of problems presenting a specific preservation plan in accordance with the function and role of the maritime enforcement organization and other government organization the point. at the same time we will try to seek measures such as a scheme that it is possible to increase the capacity.

  • The IMO has made constant efforts for global safety control of fishing vessels operation. As the result varieties of documents, for example, the international conventions, the resolutions, the recommendations and codes were adopted by the Organization. And the Organization contributed to preparing the international standards of marine safety by persuading the member countries to ratify and enforce the documents. The author inspected the content of IMO's activities and recent movement to ensure the safety of fishing vessels and their crew, and obtained the following results in connection with domestic regime. The first is the future prospect and countermeasure against revision and effectuation of "The Torremolinos International Convention for the Safety of Fishing Vessels, 1977". The Authority of Korean Government should make preparations to receive into national legislation as a performance of liability of a party country to the Convention. Secondly, the current domestic legal system has not any serious issues on the education and training for the fishing vessels crew. It is merely necessary to establish and operate the training course for the low grade marine officers.

  • This study aimed to evaluate the effectiveness of closed season policy using an integer linear programming, targeting the large purse seine fishery in Korea. In the analysis, based on Cheng and Townsend(1993), fishing effort (fishing days by month) was assumed to be distributed for profit maximization of vessels and catch of immature fish was estimated. The analytical results showed that the effects of closed season policy would vary in accordance with the monthly closures in terms of fishing profits and catch of immature fish. A closed season policy by month had different effects on fishing profits and catch of immature fish by species. It implies the importance of considering seasonal changes of fish species when limiting fishing efforts with the closed season policy.

  • 복수어구에 의한 단일 어종 자원의 평가모델은 단일 어종에 대한 복수어구의 어획노력량이 다르므로 어업별 어획노력량을 하나의 노력단위로 표준화하여, Fox (1970)에 의한 잉여생산량모델에 적용함으로써, 최대지속적생산량, 최대경제적생산량 및 적정어획 노력량의 값을 추정하였다. 여기서는 참조기에 대한 대형기선저인 망쌍끌이어업과 근해안강망어업에 대해 적용하였고, 이 두 어업에 대한 경제성 분석을 통하여 순이익을 추정하였다. 참조기에 대한 어업별 순이익의 변동을 비교 분석한 결과 두 어업의 경제성은 근해안강망어업이 대형기선저인망쌍끌이어업 보다 더 나은 것으로 분석되었으며, 두 어업의 순이익을 같게 하기 위해서는 대형기 선저인망쌍끌이어업의 노력량을 현재보다 증가시키고 근해안강망 어업의 노력량은 낮춰야 한다.

  • Fishing is considered one of the most dangerous industries alongside mining that needs further efforts to improve safety. In this study, we have investigated safety management of the gillnet fishing industry in South Korea through identifying safety level and classifying common accident types from the statements of accident com-pensation insurance payments for the last 5 years (2016-2020). There were in total 3,895 accidents and 159 fatalities with an average accident frequency of 5.34 × 10-2 per year per fisher and an average fatality of 2.18 × 10-3 fishers per year. We have also identified that 62.4% of the accidents occurred during Fishing (FS), and the most common and the most severe accident type is Slips and Trips (ST) and Other (OT) marine accidents such as collision and capsizing, respectively. The hand was most frequently injured. Finally, the risk assessment indicated that most of the accident types of gillnet fishing in South Korea have unacceptable levels of risks, and it is urgent to implement improved safety measures to reduce accidents during gillnet fishing operation. The findings of this study are expected to provide valuable data to create a safer working environment for fishers working on gillnet fishing vessels.
