우리나라 서해 중 남부 연근해의 불법어업에 대한 실태를 조사한 결과를 요약하면 다음과 같다. 1. 해양경찰청의 불법어업 단속 건수는 1998-2001년가지는 감소하는 경향을 보였으나, 2002년에는 증가한 것으로 보여 주고 있다. 2. 해양수산부 자료에서 1992-1996년까지는 완만한 증가세를 보였으나, 1997년부터는 증가폭이 크게 나타났고, 동해는 2001년부터 증가를 보였다. 남해는 1998년 기점으로 감소하는 경향을 보였고, 서해는 1997년부터 증가하였다. 특히 서해 중 남부 해역은 1998년부터 뚜렷한 증가세를 보였다. 3. 서해 중 남부의 업종별 불법어업은 소형기선저인망어업(40.9%), 유형별은 무허가어업(38.1%)이 가장 많았다. 4. 어업인들이 불법어업을 하게 된 동기는 생계를 위한 것이 27.4%으로 가장 많았고, 불법어업에 대한 어업인들의 견해에 대해서는 현실에 맞는 수산정책이 23.9%으로 가장 많았으며, 지속적인 불법어업 단속과 적절한 교육이 각각19.3%, 새로운 어업개발 18.3%, 정부의 적극적인 지원 4.6%, 기타(중국어선 단속, 어장확대, 직접실험 후 정책수립, 남획금지 등)의 순으로 불법어업의 대책을 요구하는 것으로 나타났다. 5. 설문에 의한 해양경찰관의 불법어업에 대한 의견으로는 연근해 어선이 전반적으로 불법어업을 행하고 있는 것으로 나타났으며(78.0%), 불법어업을 하게 된 동기는 생계유지를 위해서 (83.5%), 불법어업으로 어족고갈(68.9%) 등 으로 나타났다. 불법어업 근절 대책으로는 현행법 및 제도개선(68.4%)를 해야 한다는 견해를 보였다.

This paper focuses on the impacts of waste dumping on inorganic nutrients in the dumping area of the Yellow Sea, and the effect of an governmental regulation of pollution in dumping areas. The environmental variables and parameters of the dumping and reference areas in the Yellow Sea were measured during July 2009 and analyzed. In addition, the analyzed data for inorganic nutrients over the last 10 years were obtained from the Korea Coast Guard (KCG) and the National Fisheries Research and Development Institute (NFRDI). The chemical environment of the study area revealed increases in concentrations of inorganic nutrients, Chemical Oxygen Demand (COD), and Volatile Suspended Solids (VSS) in the bottom layer. On the contrary, the pH level was decreased. Most notably, the time series data of inorganic nutrients showed gradual increase over time in the dumping area, and thus, the oligotrophic waters trend toward eutrophic waters. The increases appears to be due to the disposal of large amounts of organic waste. In recent times, the wastes disposed at the area were largely comprised of livestock wastewater, and food processing waste water. The liquefied waste, which contains an abundance of nutrients, causes a sharp increase in concentrations of inorganic nitrogen in the dumping area. On the one hand, the dumping sites have been deteriorated to such an extent that pollution has become a social problem. Consequentially, the government had a regulatory policy for improvement of marine environmental since 2007 in the dumping area. Hence, the quality of marine water in the dumping site has improved.

When the 60-ton-class patrol boat '72' of the Korea Coast Guard (KCG) was on duty and she accidentally collided with another patrol boat ('207', 200-ton-class) and sank. A month-long search found a small amount of lost items, but neither the crew nor the ship was found. For the first time in 39 years since the accident, the Korea Institute of Ocean Science and Technology (KIOST) searched the boat 72 using the latest integrated geophysical techniques. A number of sonar images presumed to be of a sunken ship was acquired using a combined system of side scan sonar and marine magnetometer, operated at an altitude of approximately 30 m from the seabed. At the same time, a strong magnetic anomaly (100 nT) was detected in one place, indicating the presence of an iron ship. A video survey using a remotely operated underwater vehicle (ROV) confirmed the presence of a shielding part of a personal firearm at the stern of the sunken vessel. Based on these comprehensive data, the sunken vessel discovered in this exploration was assumed to be '72'. This result is meaningful in terms of future ocean exploration and underwater archaeology, as the integrated system of various geophysical methods is an efficient means of identifying objects present in the water.

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.
