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.

Fishing losses require a practical rather than an academic theoretical approach. As of the end of 2023, in accordance with the construction plan for the Gadeokdo New Airport, we are in a situation where we must realistically deal with losses not only to land and other obstacles in the area, but also to the fishing industry. However, in order for such compensation to be properly made, the legal realization procedures, ranging from the Land Compensation Act a general law, to the Fisheries Act, a special law, and even the Gadeokdo New Airport Special Act, must be identified and practically implemented. We will look into special cases in a special way and ultimately make efforts to resolve social conflicts in advance, and then, if unavoidable, take care to ensure that appropriate compensation for losses is provided in spite of ex-ante and ex-post rights relief. We would like to present a feasible plan. Going further from the concept and implementation method of compensation so far, shares of so-called 'post-asset' are distributed to fishermen so that other benefits can be provided to fishermen for the development of nearby areas at the same time as the construction of Gadeokdo New Airport. Effective plans will also have to be devised. In order to execute above targets, research and implementation concerning the compensation should be conducted according to the following procedures: 1) Resident and Status survey, 2) Reviewing measures for preparing a resettlement area and land for their livelihoods, 3) Selecting the candidate site for the resettlement area and land, 4) Establishment of Basic concept, and 5) Feasibility review.

Fish is an extremely perishable food product which requires proper handling soon after harvest. The present study was aimed at assessing post-harvest fish losses and preservation practices in Siavonga district, Southern Zambia. Structured and semi-structured questionnaires were used to collect data on post-harvest fish losses and preservation practices from aquaculture producers, artisanal, and commercial fishers. All the fishers who landed on the lakeshore were interviewed, while aquaculture producers were randomly selected based on the information provided by the local department of fisheries. The results of the study revealed that all the fishers experienced post-harvest fish losses at varying degrees with those losing up to 10% of the total catch being in the majority. In contrast, aquaculture producers did not report any post-harvest fish losses. Most aquaculture producers commonly used chilling as preservation practice contrary to artisanal and commercial fishers who commonly used smoking and sun sun-drying respectively. Furthermore, fish product safety and quality control were poorly practiced in the district. Lack of cold storage facilities and fluctuating weather conditions were the major challenges impacting fish post-harvest activities. Therefore, to curb the loss of revenue due to post-harvest fish losses, we propose the introduction of new technology, self-development skills for fishing communities, and enhanced access to refrigeration facilities.

We determined the feasibility of a fishing camera system using an optical fiber as the fishing line by testing a power-over-fiber (POF) module and multimode optical fiber. Operation of the remote camera module (RCM) without the battery was preferred because the removal of the charging or battery replacement section enabled a waterproof single-body type design. The average efficiency of the photovoltaic power converter (PPC) in the tested POF module was 32.6% at 820 nm, and thus, a high-power laser of at least 1.27 W was required for operating the developed RCM with an electrical dissipation of 413 mW. Because the optical fiber was wound on a fishing reel, composite loss composed of bending and tensile loss occurred. To mitigate the composite loss, we employed a simple holder that showed an improvement in the composite loss of 0.38 dB to 0.8 dB, which was considerably better than the losses without the holder.

The basic safety training for fisheries is being conducted to cope with an emergency situation and prevent the maritime accidents. A new joined person must be educated the safety training and a refresher must be completed the refresher training course every 5 year in according to the STCW-F and seafarers' Act. In order to achieve the objectives of marine safety training, it is necessary to distinguish the trainees by ship's type and the courses should be implemented in consideration of safety equipment of fishing vessels. However, since the classification criteria of seafarers' Act are unclear, the officer of fishing vessels which is over G/T 25 tons has been trained through the same course and curriculum for merchant ship's seafarers. About 80 % of domestically registered fishing vessels are small size ships(less than 100 tons) and there is not many safety equipment required by law. In case of marine accidents such as collision, the small vessel losses its buoyancy and stability caused by damage of hull. despite fisheries fall into the sea during fishing work in bad weather on the deck, there was no safety equipment by law. So fisheries must be trained by a safety training course suitable for fishing vessel. The purpose of this study is to develope the suitable course for fisheries by analysis current curriculum and rules. so suggested the basic safety training course for fisheries and institutional improvement.

Pusan is the largest fishing port in Korea, and deals with more than I million ton of fish catches annually, including catches of coastal and off-shore fisheries as well as those of deep-sea fishery. However, it hen had no fishing port facilities specialized fer deep-sea fishery since it started 30 years ago. Economic and physical losses resulting from this have teen enormous. Although fishing port facilities are a part of infra-structures built by Governments, the construction of them has been delayed due to financial difficulties of Central or local governments. To overcome this harsh situation to which deep-sea fishery cooperations faced, some cooperations have decided to construct fishing port facilities including fish-pier specialized for deep-sea fishery in Gamcheon port. The construction expenses of these facilities were financed by private funds to which they themselves jointly contributed. As a result, a fish-[pier, which has the capacity of serving one fishing vessel of 10, 000 ton or four of 5, 000 ton or four of 1, 000 ton at the same time, will be opened in here by 1994. The paper examines the master plan to revitalize the deep-sea fisheries industry in a deep depression with the opening of these physical facilities. The framwork of the plan is pursued in two different aspects, which are both hardware and software. In a hardware aspect, the plan in to develop Pusan into a city which is suitable for one of the best fishing ports in the world. That is, it is to develop the city into a place famous for sightseeing as well as the distribution and processing of fish-products centering around fish-piers. On the other hand, in a software aspet, it is regarding improvement of the distribution system of fish-products. One way to do that is to make up some deficiencies of the current system of a producers' joint sale. And the other is to establish an exchange of fish-products futures. Through these institutions, we could abrsorb speculative funds, which would otherwise be invested in speculation on fish-products, into productive investment opportunities, We believe that if the plan is realized, the deep-sea fishery in Korea will revive from a long-tasted depression and make progress to become one of the mai industries of Korea.

The paper is to serve as a guide for deciding on a desirable direction for the vessel buyback program, reviewing their performance and economic effects from fish harvest reduction due to not reaching MSY. Compared with maximum willingness to pay for vessel buyback programs designed to avoid economic losses occurring as a result of overfishing, the portions of investment costs for buyback program are so small comparatively to the range of 0.32% to 12.19% at the annual base. The economic loss effects occurred in terms of the reduction of fishing harvest are comprehensively estimated at the present value of 30,877 billion won since 1971, and exceeded the revenues for fish harvests from 1999. In order to resole fish stocks through a vessel buyback program, this paper recommends that the yield should be reduced to less than the intrinsic growth rate. Otherwise, the buyback program policy eventually fails regardless of the temporal effect of benefits. This paper further argues that technical policy tools such as fishing grounds, fishing seasons, size of fish and minimum size of meshes should be effectively utilized.

1994년 유엔해양법 발효 이후 해양활동의 무대가 배타적 경제수역과 대륙붕까지 확대됨에 따라 각국은 자국의 권리를 강화해 나가고 있으며 국제사회는 국익을 확보하려는 다툼이 더욱 치열해지고 있다. 이와 관련하여 해양주권에 대한 연구가 많이 이루어졌으나 정책적인 연구에만 국한 되었을 뿐 실증적인 연구는 전무한 실정이다. 따라서 본 연구에서는 해양주권에 대한 실증적 인구를 위해 최근 빈번히 발생하고 있는 중국어선이 불법조업 사례를 대상으로 연구를 실시하였다. 해양주권 침해의 요인이 되는 요소를 선정하여 상관분석과 다중 회귀분석을 실시하였으며 또한 해양주권 침해의 경제적 파급영향을 분석하였다. 분석결과, 중국의 수산물 증가로 인해 발생한 중국 불법조업의 중가는 우리나라의 수산물 생산량을 감소시켰으며 이는 우리나라 어가 경제에 손실을 미쳤을 뿐만 아니라 우리나라 가계 경제에도 큰 부담을 초래 하였다.
