The Yellow Sea and the East China Sea are the most important fishing grounds for the fishing industry of Korea, China and Japan which are major coastal states of these Seas. But the fishery resources in these fishing grounds are almost exhausted and also the sea region is seriously polluted. Accordingly an international joint countermeasure is necessary to recover the fishery resources and to keep the fishery a continuous industry. The authors inspected the existing fishery policies and international fishery relationship of the three coastal states, and suggested rational conservation and management regime of the fishery resources in these sea regions. 1. At present the legal status of the sea region beyond territorial sea is the high sea, for that reason the international cooperation is urgently needed to establish common regime for conservation and management of the fishery resources. 2. A series of scientific research on ecological system of fishery resources must be carried out in the sea region first of all for that purpose. 3. The existing Korea-Japanese Fishery Agreement and Sino-Japanese Fishery Agreement should be reformed to coincide with the new legal order of the UNLOS Convention, and the Sino-Korean Fishery Agreement should be concluded newly on the identical line. 4. As a conclusion, a joint conservation and management regime through a regional fishery organization or a individual conservation and management regime through the promulgation of exclusive economic zone by each state can be suggested to resolve the fishery resources conservation problem in the Yellow Sea and the East China Sea.

As the population grows, the importance of the fishery industry continues to rise. It is therefore vital to support and promote sustainable fishery industry. However, the fishery production has been declining, mainly due to overdevelopment and depletion in fishery resources and stricter limits on development limits caused by growing concerns over the marine environment and ecology. Recently, international activities related to marine environmental and its ecosystems conservation, have been vigorously pursued. The United Nations Convention on The Law of The Sea has stipulated the protection and conservation of the marine environment, and the implementation of fishery resources development, made in harmony with the environment and fishery resources and based upon scientific findings and principles has become important. Accordingly, fishery industry must pay thorough attention to marine ecological and environmental problems and its international fisheries regime. Fisheries development can affect fishery resources, their environment and ecosystems. Adverse ecological effects resulting from fishery resources development practices in general include overdevelopment and incidental development of non target species, physical degradation of seabed habitants and degraduation of water quality. It has now become more important than ever to build up fishery resources development while achieving the conservation of biodiversity and the marine environment, as well as the restoration of destroyed ecosystems. To maintain fishery industry, it is necessary to develop bioeconomic fishery production system and industry policies for the ESSD(environmentally sound and sustainable development) given that maintenance of a favourable marine environment will ensure the fishery resources productivity. These bioeconomic system and policies are necessary to ensure the sustainability and viability of the fishery industry under ESSD fisheries concepts.

The primary purpose of this paper is to introduce the cases of fishery co-management, particularly in Korea. In recent, the fishery co-management between the government and fishermen has been brought an important shift of paradigm in a part of Korean fishery management policy. In case of Korea fisheries area, three fisheries cooperatives(which refer to purse sein fishery, trawl fishery, stow net fishery) have a minority of co-management programs. Generally, the main method of fishery co-management programs is 'Fishery Closures' among the programs, and others are restriction of fishing gear and fishermen educations. In spite of the efforts and time consumes of Korean government and fisheries cooperatives, much to our regret that it is hard to confirm visible results in an increased amount of fisheries resources so far because of the time constraint, namely fishery co-management programs have been conducted just since two to three years before. However, what's certain is that fishery co-management programs make it possible to positively effect on both of area in fishermen and fisheries resources. Accordingly, it is necessary that Korean government and fishermen should extend the fishery co-management to other fishery areas as soon as possible we can in order to efficiently reduce administrative costs and effectively reserve fisheries resources.

This study deals with the evolutional history of the holding and utilization of fisheries resources in Korea. Fisheries resources have the basic characteristics of the density dependent self-regulating renewable and common property resources, Irrational utilization of fisheries resources is mainly due to the unlimited access to the resources. The holding and utilization of fisheries resources in Koryo era was opened to everyone. But it was nationalized in the early Yi Dynasty. The purpose of its nationalization was to provent the paticular powered-man with their monoplized holding and to levy fisheries tax. Eoeop-peop, the first modern fisheries law in Korea, was enacted as a part of the invasion policy of Japan in 1908. With the japanese annexation of Korea in 1910, the Japanese Government established a new institutional system of fisheries as a part of an overall reformation of the institutional for an implementation of the colonial policy. It was very the new enacted Fisheries Law (Gyogyorei). Also the Government enacted compulsorily another new Fisheries Law (Chosen Gyogyorei) with its adjunct laws and regulations revise the institutional system of fisheries on May 1, 1930. After Eoeop-peop enactment, the fisheries resources in Korea could be used only under the license, permission, and statement. After Korea was from Japan in 1945, Korea Government at last enacted the new fisheries law (Susaneop-peop) in 1953. The goal of Susaneop-peop was to achive the general usage and protection of the fisheries resources, and to attain the development and democratization of the fishery in Korea. This law was amended 13 times until 1990. The license fishery have a legal right on the fishery, called a fishery rigt. This right means a right of exclusive occupation and utilization of a unit of the inshore fishing grounds. The main evolutional issues of license fishery are as the following : 1) the foundation of the exclusive usable fishery right(1911, Gyogyorei), 2) the deletion of the settled U9space lift net and settled space sein net fishery, and the expansion of the cooperative fishery-No.1, 2, and 3 type cooperative fishery-(3rd amendment, 1963), 3) the deletion of the No.2 and 3 type cooperative fishery, and the separation of the culturing fishery in No.1 and 2 type culturing fishery (13th amendment, 1990). The effective period of the license fishery was amended as the following : 1) 1908(Eoeop-peop) : within 10 years, renovation system, 2) 1929(Chosen Gyogyorei) : within 10 years, unlimited extension system, 3) 1971. 7th amendment : 10 years, renovation system, 4) 1972. 8th amendment : 10 years, only 1 extension system, 5) 1975. 9th amendment : 5-10 years, only 1 extension system, 6) 1990.13th amendment : 10 years, within 10 years of total extensional years. The priority order of the fishery license was established in 1953 (Susaneop-peop). The amendment of it is as follows : 1) 1953. enactment \circled1 the fishing grounds that the fishery right is extablished 1st order : the existing fishery right man, unlimited renovation 2nd order : the corporate that the regional fisherfolk organized 3rd order : the rest experienced fishermen \circled2 new fishing grounds 1st order : the corporate that the regional fisherfolk organized 2nd order : the rest experienced fishermen 2) 1971. 9th amendment \circled1 the fishing grounds that the fishery right is established 1st order : the existing fishery right man, unlimited renovation 2nd order : the Eochongye that the regional fisherfolk organized 3rd order : the regional fishery cooperative that the regional fisherfolk organized 4th order : the rest experienced fishermen \circled2 new fishing grounds 1st order : the Eochongye that the regional fisherfolk organized 2nd order : the regional fishery cooperative that the regional fisherfolk organized 3rd order : the rest experienced fishermen 3) 1981. 10th amendment \circled1 the inside of No.1 type cooperative fishing grounds 1st order : the Eochongye that the regional fisherfolk organized 2nd order : the regional fishery cooperative that the regional fisherfolk organized 3rd orer : the rest experienced fishermen 4) 1990. 13th amendment \circled1 No.1 type cultural fishery 1st order : the Eochongye that the regional fisherfolk organized 2nd order : the regional fishery cooperative that the regional fisherfolk organized 3rd order : the rest experienced fishermen \circled2 No.2 type cultural and settle fisher : general priority order The effective period of the permission fishery was amended 6 timed. First, it was within 5 years and renovation system (Eoeop-peop). Now it is 5 years and renovation system. The effective period of the statement fishery was amended 4 times. First, it was within 5 years, and then was amended within 3 years(Chonsen Gyogyorei). Now it is 5 years.

This study discussed the international reorganization of fisheries in the East China Sea and the Yellow Sea, for the cases of Korea, China and Japan, through the fishery competition and the division of sea areas and resources. In these sea areas, each country has done mutual operation, which causes the fishery competition and controls fishery development. Besides, Exclusive Economic Zon(EEZ) established in 1996 resulted in the prominent changes of fishery development as well as fishery relationship among each country, demands reorganization of fisheries. New fishery order in these sea areas is controlled by BEZ system. The fishery reorganization according to EEZ is a common issue of each country and it also includes the importance of mutual fishery agreement. Resources of fisheries could be used continuously under reasonable management. Each country should consider the stability and existence of fisheries in the international viewpoint. At this point of time, those should be considered such as adjustment of interests according to the division of sea areas, establishment of resource management system and insurance of fishery management, for the subject of fishery reorganization.

The Japanese fishery management system has been established on the basis of various experience accumulated over many years. The fishery management system in Japan, one of the oldest fishery management systems in the world, is aimed at ensuring comprehensive utilization of the water surface and developing fishery productivity, by giving protection of the breeding environment of aquatic animals and plants, enabling the appropriate use of fishery grounds, preventing and solving disputes over fishery grounds and making other fishery adjustments. Japanese Fishery Law has been changed largely into (1) The Feudal Era(to 1900), (2) The Oldest Fishey Law(1901~48), (3) Current Fishery Law(1949 to present). Japanese fishery legislation is designed as a single package combining coastal, offshore and distant-water fisheries. During the period of the old fishery law, numerous conflicts arose over the joint use of fishing grounds and fish stocks. Such conflicts occurred among users of the same gear as well as between users of different gears or of different sizes of fishing craft. Large scale conflict sometime occurred between neighbouring fishing communities due to a lack of fairness in principle and coordination in practice. Therefore, the new fishery law enacted in 1949. This law was designed primarily to realize the most effective and rational use of fishing grounds and fishery resources, the basic philosophy being that, through democratic organization by fishermen themselves, productivity would be stimulated and incomes and living standards eventually improved. Nowadays, Community Based Fisheries Management through democratic organization by fishermen themselves have to enforce at coastal fisheries. This Community Based Fisheries Management manage to fishery resources by fishermen themselves and harvest in collaboration with that resources. Therefore, this paper is intended to briefly to describe the entire system and the historical development of Japanese fishery legislation in order to assist in reform of our country fisheries management regime.

The Norwegian coastal area is the most efficient region for fishery production in the world's oceans, the Norway is the world's top 10 fisheries countries through efficient fishing and fishing aquaculture technology and its scientific management of fisheries bio-resources, with Norwegian salmon having attained the world's highest level. In the late 1980s, fisheries resources were depleted due to overfishing and fish diseases, resulting in a crisis in the fishing industry that lasted until the early 1990s. Since the national fishery emergency, people involved in the fishing industry, including fishermen, research scientists, and government officers, have tried to overcome the challenges facing the industry and identify an appropriate management model for fisheries bio-resources in the Norwegian coastal area. First, research vessels were used to monitor water and sediment conditions and fishery species, with the long-term aim of predicting fishery resources in real time and collecting information on species diversity, abundance, and distribution. Second, a "Healthy Fish Project" was promoted to counter natural disasters and fish disease problems with the development of vaccines against viruses and bacteria, eventually allowing for a decrease in the use of antibiotics and the production of notably healthier fish in the 2000s. Third, a systematic management model was developed to help with preparations for decreases in the total number of fishermen and increases in the proportion of elderly fishermen in the fishery industry using the development of automatic fishing aquaculture systems and short-chain systems. We could learn from the Norwegian model of fisheries bio-resources, management and could adopt it for the preparation of fishery bio-resources management policy for South Korean coastal areas in the near future.

In Korean waters, there are two color types (blue and purple) of the blue crab Portunus trituberculatus. The blue type is common, but the ratio of the purple type has increased in landings. To determine whether there were significant morphometric or genetic differences between the blue and purple types, crabs caught from the West Sea of Korea were examined. Based on covariance analysis, there were significant differences in 1 of 10 morphometric characteristics of males between the two types, in none of the ten characteristics for females. Using amplified fragment length polymorphism (AFLP) DNA fingerprinting, no specific AFLP marker was detected for each type. The heterozygosity and genetic diversity were very low. Analyses of pairwise distance, the Fst index, and genetic similarity revealed similar results, with very low genetic differentiation. Therefore, there is no significant difference between blue and purple types of the crab from the West Sea of Korea, and the two types in the West Sea can be managed as one stock.

We demonstrate herein the synthesis and modification of magnetic nanoparticles and its use in the immobilization of the lipase. Magnetic $Fe_3O_4$ nanoparticles (MNPs) were prepared by simple co-precipitation method in aqueous medium and then subsequently modified with tetraethyl orthosilicate (TEOS) and 3-aminopropyl triethylenesilane (APTES). Silanization magnetic nanoparticles (SMNP) and amino magnetic nanomicrosphere (AMNP) were synthesized successfully. The morphology, structure, magnetic property and chemical composition of the synthetic MNP and its derivatives were characterized using transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR) analysis, X-ray diffraction, superconducting quantum interference device (SQUID) and thermogravimetric analyses (TGA). All of these three nanoparticles exhibited good crystallization performance, apparent superparamagnetism, and the saturation magnetization of MNP, SMNP, AMNP were 47.9 emu/g, 33.0 emu/g and 19.5 emu/g, respectively. The amino content was 5.66%. The AMNP was used to immobilize lipase, and the maximum adsorption capacity of the protein was 26.3 mg/g. The maximum maintained activity (88 percent) was achieved while the amount of immobilized lipase was 23.7 mg $g^{-1}$. Immobilization of enzyme on the magnetic nanoparticles can facilitate the isolation of reaction products from reaction mixture and thus lowers the cost of enzyme application.

Despite international laws and government efforts, most of the world's fishery resources and ecosystems have continued to decline since the 1970s. In response, international non-governmental organizations have launched sustainable seafood movements and attempted various strategic approaches. These include the "boycott" strategy of the 1980s and 1990s, and the expansion of certified fisheries through Fishery Improvement Projects (FIPs) in the 2000s. According to data from the Marine Stewardship Council (MSC), currently there are 274 MSC-certified fisheries in 63 countries, covering 179 species, and 264 fisheries engaged in FIPs in 67 countries, covering 233 species. In Korea, the adoption of private fishery governance, which complements international and domestic fishery laws and government management, remains relatively low. Therefore, we examined private fishery governance with respect to its governance, interaction with laws, credibility, legitimacy, current status, and key considerations for its implementation. We emphasize the utilizing MSC fishery certification schemes as an audit approach to sustainability, implementating FIPs to address the fisheries sustainability gap, using councils for leadership, and securing government financing for fisheries with no market incentives.
