Since the onset of its economic reform and the open door policy in the late 1970s, China's overall economic growth rate has been continuing about 10% per year. The marine sector is not allowed exception, aquatic products increased sharply from 4.66 million MT in 1978 to 36.02 million MT in 1997, and then China is remained the largest producing country in the world aquatic market and her role would be expanded. Korea having a common boundaries to China is subjected unescapably both in domestic and export markets by the influence of the remarkable growth of China's aquatic products. If China were admitted entrance of WTO(World Trade Organization)in the near future, her influence is getting more serious. Well, we are necessary to understand the characteristics of China's aquatic products and to review fishery policies implemented by the China government. This paper is organized into two major parts, the one includes the structural changes of aquatic products, fishing and cultivating in the coast, latent and estimated production in China, and the other includes the main contents of fishery policies and measures of government administration. A characteristic of China's aquatic products is that cultivated production, especially, shellfish outputs continues to rapid increase. The major means of administration are an execution of fishing license system and setting up no-fishing zone and closed season for fishery. China is no longer a marginal player in international economic and world aquatic market. So, we will not only understand China's aquatic conditions and problems, but will also see the usefulness in continuing the cooperative relationship for a long time to come.

The aim of this study was to conduct an ecosystem-based fishery risk assessment of tuna fisheries in the Western Indian Ocean. We selected gillnet, purse seine, hand line, baitboat, and longline fisheries as the target fisheries method, and selected longtail tuna (Thunnus tonggol), narrow-barred Spanish mackerel (Scomberomorus commerson), kawakawa (Euthynnus affinis), skipjack tuna (Katsuwonus pelamis), yellowfin tuna (T. albacares), bigeye tuna (T. obesus), albacore tuna (T. alalunga) and swordfish (Xiphias gladius) as the target species. The risk score for the size at the first capture in sustainability objective was high, especially, for the purse seine and baitboat fisheries using the fish aggregating devices (FADs). The risk score for the bycatch in the biodiversity objective was high for the gillnet fishery, and the gillnet fisheries using FADs showed high risks for the habitat quality objective due to the loss of the fishing gears. With regards to the socio-economic benefits objective, the risk score of the sales profits was low due to high sales of the tuna fisheries. The ecosystem risk score in the Western Indian Ocean was estimated to be moderate, although management is required for some of the indicators that have high-risk scores.

This paper seeks to find out possibility of introducing market order into Korean fisheries regulatory system. Hayek tells us that market order is equivalent to spontaneous order, while regulations are man-made order created based on incomplete knowledge. He also sees market competition as a discovery procedure of knowledge and information. From this perspective is discussed Korean fisheries regulatory reform-particularly issues of establishing property right on fishery resources. It appears that there is quite a large room for substituting market functions for the regulations regarding fishery resources management, even though fishery resources have a very nature of common pool. Advanced fisheries suggest that successful regulatory reform require a well-prepared strategic plan and check list. In addition, the government should be able to secure sufficient monitoring and surveillance power and to play an important role as a fair supervisor.

The study examined overuse of the fishery resource. Influence of fishing activity was estimated by application of Schaefer model's. Fishing efforts that produced the maximum sustainable yield were determined in the model, allowing the effect of overfishing to be assessed. In the model, a wide variety of fish species as well as crustaceans and shellfish were susceptible to overfishing, while mollusks were not. Overfishing by modern techniques exacted a greater toll than more traditional methods. The results of the modeling study suggest that the 'Buy bag' input-control system of fisheries resource management warrants consideration, as does modernization, expansion and strengthening of self-control management of the fishery resource. Finally, more effective efforts in dissemination of policy information and education concerning the fishery resource are needed.

The fisheries resources control system in the Fisheries Act of Korea is introducing technical management method and input control method that controls fishing effort. Fishing effort control system of Korea aiming at realizing the maximum sustainable yield does not regulating the limitation of fishing quota and the limitation of fisheries object target fish. Therefore fishing operators who have fishing permit can use fishery resources without any restriction of fishing quota. But there are no rules that can controlling capacity of productivity of fishing by developing of fishing technic and fishing gear. For those reasons, productivity of fishing is superior to reproductivity of fisheries resources. Therefore, the Fisheries Act of Korea rearranges a legal basis for an introduction of fisheries resources management system by TAC, but the contents to be possible for a legal guarantee is not included and it is exceedingly defective as abstract and institutional devices. And that the affairs to be required for an enforcement of the said regime was placed in an administrative mandatory legislation and the danger to be degenerated is high in accordance with the bureaucratic self-righteous and/or the coercion of group's interest concerned and accordingly its substitute legislation system is keenly required. TAC system that is going to be introduced in our country is expected to enforce the Olympic fishing method and the individual quota method in parallel. This method is not certainly proper, because it occurs to overcapitalize and to compete fishing amounts between fishery operators. So as to prevent overcapitalization and fishing competition between fishery operators, and the exhaustion of coastal fisheries resources, individual transferable quota system should be introduced in Korean sea. Accordingly this thesis has attempted to constitute a view to improving problems of the traditional fisheries resources control system and introducing TAC fisheries resources control system.

Background: Fish and fishery products (FFPs) unintentionally contaminated with various environmental pollutants are major exposure pathways for humans. To protect human health from the consumption of contaminated FFPs, it is essential to develop a systematic tool for evaluating exposure and risks. Objectives: To regularly, accurately, and quickly evaluate adverse health outcomes due to FFPs contamination, we developed an automated dietary exposure and risk assessment system called HERA (the Human Exposure and Risk Assessment system for chemicals in FFPs). The aim of this study was to develop an overall architecture design and demonstrate the major features of the HERA system. Methods: For the HERA system, the architecture framework consisted of multi-layer stacks from infrastructure to fish exposure and risk assessment layers. To compile different contamination levels and types of seafood consumption datasets, the data models were designed for the classification codes of FFP items, contaminants, and health-based guidance values (HBGVs). A systematic data pipeline for summarizing exposure factors was constructed through down-scaling and preprocessing the 24-hour dietary recalls raw dataset from the Korea National Health and Nutrition Examination Survey (KNAHES). Results: According to the designed data models for the classification codes, we standardized 167 seafood items and 2,741 contaminants. Subsequently, we implemented two major functional workflows: 1) preparation and 2) main process. The HERA system was developed to enable risk assessors to accumulate the concentration databases sustainably and estimate exposure levels for several populations linked to seafood consumption data in KNAHES in a user-friendly manner and in a local PC environment. Conclusions: The HERA system will support policy-makers in making risk management decisions based on a nation-wide risk assessment for FFPs.

Fisheries finance is divided into the policy time of long period of time and low interest and the special financing institutions, such as Fisheries Co-operatives. Union system finance is the system finance, which supports the fisheries system organization. Fisheries Co-operatives in cities, towns and villages are the independent management objects. Prefecture federation of Fisheries Co-operative is in prefecture stage. Norm Chukin Bank is in national stage. Each shares functions in these three stages, and finance is performed systematically, Fisheries policy finance comprises government financial institution capital such as the Agriculture, Forestry and Fishery Finance Corporation whish is based on the capital of a country or a prefecture financial fund, and fishery Modernization Capital used as financial funds through the government. Moreover, to complement such finance institutionally, Fisheries Credit Foundations, Agriculture and Fisheries Saving Insurance Corporation and National fisheries Co-operative Trust Enterprise Mutual Aid system have been established

In this study, to provide basic information for design of a large-scale recycling system for fishery by-products, the food nutrient components, fertilizer components, and microbial composition of fertilizers and feed which were made of fishery by-products were analyzed before and after fermentation. The results of the analysis of the edible portion of fishery by-products indicated that calories per 100 g of crustaceans were the highest followed by those of fish and brown algae in order of precedence with values as follows; Korean Krill 94 Kcal, Portunus trituberculatus 65 Kcal, Lophiomus setigerus 58 Kcal, and Undaria pinnatifida 16 Kcal. As for changes in amino acids per 100 g of fishery by-products between before and after fermentation, calories per 100 g of P. trituberculatus decreased by 74.7% from 15.7 g to 4.0 g, that of L. setigerus decreased by 61.1% from 11.9 g to 4.6 g, that of Korean Krill decreased by 53.5% from 11.6 g to 5.4 g, and that of U. pinnatifida decreased by 49.4% from 1.7 g to 0.9 g. Among amino acids, those contained in fishery by-product fertilizers (liquid fertilizer) in large amounts were shown to be Glutaminic acid, Aspartic acid, Glycine, Lysin, and Leucine. The lipid content of Korean Krill decreased by 11.9% from 3.2 g to 2.8 g, that of L. setigerus increased by 2.0 times from 1.1 g to 2.2 g, that of P. trituberculatus increased by 4.5 times from 0.4 g to 1.7 g, and that of U. pinnatifida increased by 9.4 times from 0.2 g to 1.9 g. The ash (mineral) content of P. trituberculatus decreased by 82.5% from 26.2 g to 4.6 g, that of U. pinnatifida increased by 27.6% from 3.3 g to 4.2 g, that of Korean Krill increased by 21.9% from 3.1 g to 3.8 g, and that of L. setigerus increased by 88.7% from 1.2 g to 2.2 g. The microbial composition of liquid fertilizer using recycled fishery by-products was shown to be Bacteria, Actinomycetes, Fungi, Yeast, and Lactobacillus sp.
