As UN Convention on the Law of the Sea(UNCLOS) came into effect as of Nov. 1994, not only Korea, but neighboring countries such as Japan, China declared their own EEZ and took a necessary measures to secure their EEZ area, accordingly a variety of dispute kept on arising between those countries.
Korea made fishery agreement with Japan and China, afterwards chinese fishing vessels often crossed over korean EEZ and engaged in illegal fishing activities which has been increasing year after year.
Lead agency in Korea, Korea Coast Guard made frequent surveillance and reconnaissance to prevent their activities and arrest illegal fishing boats. With KCG's strong countermeasures, numbers of chinese fishing boats in Korean EEZ have been increasing.
However, KCG patrol can cover only part of wide EEZ area with some limitation of r3sources and technical defects and so on.
In this regards, the author studied and examined to find more effective and efficient patrol method to keep the chinese fishing vessels from fishing into korean EEZ, analyzing meteorological condition, oceanographic condition, seasonal changes of fishing ground and additionally performed the analysis of illegal chinese fishing boats arested by KCG as well as current KCG
s patrol system against illegal activities with benchmark of USCG and JCG system, then finally suggest the integrated patrol systemn as long-term patrolling strategy as follows.
(1) In the West Sea of Korea, strong wind belt forms in the southern area and neighboring sea of Jeju Is. where high seas appears as well. In Jinhae Bay, accordingly high endurance cutters should be deplyed in this area.
(2) According to illegal chinese fishing boats arrested by KCG, numbers of fishing boats have been increasing and the size of those vessels tends to be larger recently. and the fishing area by those vessels looks to be moving northward from southern part in winter to northern part as water temperature becomes warmer, then moves back southward with drop of water temperature, which indicate approximate trajectories of illegal fishing area.
(3) Benchmarking with USCG and JCG, KCG is required to introduce the integrated patrol system which is composed of cutter, aircrafts(rotary wing and fixed wing), land-based facilities and satellite. Since KCG's patrol capabilities lack of high endurance cutters, aircarfts and land-based facilities to process intelligence and relevant data, the Integrated Patrol System can be operated so far. Therefore KCG advisably make a plan to prepare long-term patrol strategy with augmentation and modernization of patrolling resources.
