대부분의 나라에서는 어선의 위치발신장치를 이용하여 어선 조업상황을 모니터링 한다. 우리나라도 어선의 위치발신장치를 이용하여 어선 조업량, 불법조업 유무를 판별한다. 현재까지는 어선의 불법조업 유무 판별은 어선의 위치정보 기반으로 이루어 졌으나, 허가받지 않는 어구를 사용하는 불법조업에 대한 판별은 불가능 하였다. 이에 본 논문에서는 어선 항적과 조업면허 데이터를 이용하여 데이터 기반의 어선 조업 판별모델을 개발하고자 한다. 이를 위해 어선 항적데이터를 시계열 단위로 전처리하여 학습 이미지들을 생성하고, 해당 어선의 조업면허 정보를 레이블로 하여 학습 데이터를 제안하는 딥러닝 모델에 적용한다. 제안하는 방법의 검증을 위해 1년 동안 제주 주변해역에서 조업하는 어선의 선박자동식별장치의 항적데이터를 수집하여 실험을 하였다. 실험 결과 제안한 방법의 분류정확도는 71.5%를 얻었다.

지구온난화에 따른 우리나라 주변 환경의 변화와 최근 중국 불법 어선의 연근해 어업 자원의 고갈 등으로 인해 우리나라 연근해 어족자원을 보호할 필요성이 증대되고 있으며, 지속 가능한 어업을 위해서는 어획물의 종류와 양을 정확히 파악하고 불법 어업에 대한 철저한 감시 및 관리가 필요하다. 이러한 시공간적으로 다양하게 변하는 생태 및 어장 환경 정보와 선박에 대한 정보를 통해 해양관측과 위성 원격탐사를 동시에 이용함으로써 근해와 원양 생물자원 실태를 관측하는 것이 가능하다. 본 연구에서는 NOAA-20 위성의 VIIRS (Visible Infrared Imaging Radiometer Suite) DNB (Day & Night Band) 영상을 기반으로 추정한 야간 불빛 자료를 활용하고자 한다. DNB 불빛 영상은 낮은 조도의 불빛을 감지하여 그 정보를 보여 준다. 야간 불빛 자료에 포함된 구름 부분을 마스킹하기 위해 NASA의 신규알고리즘이 적용된JPSS-JRR-CloudMask 기술을 이용하였다. 이번 연구에서는 구름의 영향이 없는 날짜를 선별한 후 AIS 정보에서 어선의 정보를 추출하여 검증 자료로 사용하였다. 실제 선박의 정보를 이용한 위성 불빛 자료의 검증을 통해 위성자료의 신뢰성을 확보하고 향후 불빛과 선단 규모의 상관관계 분석 및 어선의 분포 경향 분석을 통하여 우리나라의 어장환경 분석에 활용 가능할 것으로 기대한다.

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.

The economic and social bad influences of the illegal fishery bring about the results of the fishery resources exhaustion, of the fishery disorder and of the obstruction to sound management for fishery. The typical illegal fishery conducted in the coastal and offshore area of Korea can be divided as follows; fishery conducted by legally unauthorized method, fishery without permission from the Government, and fishery conducted in contravention of the laws and regulations concerning the fishing vessel, fishing gear and fishing method etc. The major reasons of origination of the illegal fishery in the coastal and offshore area of Korea are; Firstly, almost of the fishermen are poorly equipped in economical scale, Secondly, it is very easy to approach the illegal fishery because the domiciliation condition of the fishing village is deteriorated. Thirdly, almost of the fishermen are lacking in lawabiding spirit. Fourthly, the insolvent and unstable fisheries management policy with the lukewarm enforcement of the fisheries laws and regulations by the Government. Fifthly, the small scale family supporting fisheries are widespreaded. Sixthly, to retrieved the economical difficulties the fishermen are easily led astray the illegal fishery. As a conclusion the authors made some suggestions to stamp out the illegal fishery by this study. For the first, temptation fishermen into lawabiding fishery through intensification of the penal regulations is required. Second, simplification of the fishery type through combination of resemble fishing methods is required. Third, actual improvement of the fundamental fishery permission regime is required. Fourth, Introduction of the self-regulating or co-management system for the fishery management is required.

Illegal fishing is often cited as a principal cause of the failure of fisheries management, expecially fishing efforts regulations in traditional fisheries management. Usually, illegal fishing problems are perceived to be equivalent to inadequate enforcement, and policy prescription then follow to strengthen enforcement programs. The purpose of this paper is to analyze the illegal fishing behavior relatively recent emphasis on fishing efforts regulations in traditional fisheries management. The analysis focuses on measuring, explaining and developing the effectiveness way of enforcement strategies responding to imperfectly managed fishing efforts regulations through illegal fishing behavior and avoid enforcement fishing efforts measures. A model of fishermen fishing behavior and profit-maximizing decision making is analyzed to determine optimal fishing at individual fisherman level in response to fishing efforts regulation. The results of economic analysis of the enforcement of illegal fishing in traditional fisheries management results are as follows: First, illegal fishing will occur only if enforcement effort is not so high as to remove the incentive to do so, and if the effectiveness of avoidance is not too great, nor its cost too low. Second, avoidance effort will occur at a level jointly proportional to the extent of illegal activity and of enforcement; for given levels of the latter, the desired avoidance effort increase with its effectiveness and decrease with its cost Third, to improve the effectiveness of enforcement, understanding avoidance behavior appears to be crucial to any efforts. Forth, enforcement and fishermen behavior interact depends strongly on characteristics of avoidance, specifically its cost and effectiveness. When avoidance is neither too cheap nor too effective, the interaction is regular. Fifth, in this case, at low levels of enforcement, fishers respond to increases in enforcement by increasing avoidance, but at higher enforcement levels, it becomes uneconomical to continue to do so, and avoidance decreases with enforcement. Sixth, illegal fishing activity decreases steadily with enforcement, so the fishery manager is able, in theory, to reduce illegal fishing toward zero by increasing enforcement. If, however, avoidance is very inexpensive and/or very efficient/ then the optimal level of avoidance will increase indefinitely with increasing enforcement. Finally, less fishery enforcement is required if fishermen have less incentive to overfish, and fishermen have less incentive to avoid fishery enforcement measures.

The fisheries resource in waters under the jurisdiction of Korea is being endangered by unlawful fishery. The Korean government exerted great efforts to establish the public order of water, but the number of the exposed unlawful fishing violations has increased for last 10 years. The system to guide fisheries regulatory noncompliance of Korea is limited to the use of fishing guidance patrol boats. For strength of monitoring and surveillance systems, the government needs to phase in Vessel Monitoring System. But there are some studies for that. The defects of present monitoring practice can be drawn from the facts described above. The qualification of the fishery control official one of most important element of fishing control system, is defined as any officer who is charging on fishing. For clear law enforcement the qualification should require considerable experience and knowledge. Korean coast guards have problems on guiding unlawful fishing violations because of the absence of administrative authority by comparison with the fisheries guiding officer, who has both authorities on administration and jurisdiction. To draw some judicial problems this research presents a analysis on the fishing control system. The research suggests the improvements to compensate the defects.

This study estimated quantitatively the loss of the fisheries due to China's illegal fishing that prevailed in the EEZ of the country in recent and has been an object to present a basic data in the implementation of government policy as to strengthen the enforcement capacity, setting up the direction of the crackdown of Chinese through to figure out an objective loss according to that. The analyzed result of this study setting a reasonable scenario, fisheries resources reduction is estimated about 67.5 million ton and the estimated amount of the loss is about 1.3 trillion won. This is 21.2% of about 318.3 ten thousand tons of the total fishery production of the country and accounts for 61.9% compared to coastal and offshore fisheries production. Therefore it is a very serious problem due to China's illegal fishing in Korea fisheries sector. It is significant to the point that estimating the qualitative and quantitative losses that can achieve a realistic and effective policy.

남극해에서는 우리나라를 포함한 연안 강대국들의 원양어업이 활발히 성행하고 있다. 주인 없는 남극해의 생태계를 보호하기 위해 조업 국가들은 남극해양생물자원보존위원회를 만들고 협약을 맺어 일정한 어획량만 조업하고 금지기간과 금지구역을 설정하여 불법조업을 방지하고 있다. 남극해에서 조업하는 어종 중의 하나가 이빨고기(tooth fish)인데 비싼 값 때문에 불법조업이 있는 경우가 많다. 한 배의 조업성과는 CPUE(catch per unit effort)로 나타낼 수 있고, 한 지역에서 조업한 배들의 CPUE는 단일 또는 혼합 극단분포 형태를 가진다. 단일 극단분포일 경우 이상점 탐색은 상위 백분위수를 이용하면 된다. 본 논문은 자료가 혼합 극단분포인 경우 이상점 탐색을 위한 통계적 방법을 연구하고자 한다. 본 연구에서는 자료에 적합한 혼합 극단분포 모형을 EM 알고리즘으로 추정한 후 로그 가능도함수 값을 이용하거나 사후 확률을 이용한 이상점 탐색 알고리즘을 제안한다. 이 방법을 남극해 조업 데이터에 적용하여 시뮬레이션 한 결과 통계적 방법 적용의 가능성을 보여주었다.
