  • The fishing ground surrounding Wangdol-cho is not only overexploited by the littering of dilapidated fishing net and equipment, but also by fishermen's overfishing, surpassing optimum fisheries resources. In addition, increasing fishing efforts (number of fishing vessel and fishing net, etc) contribute to the deterioration of fishing ground, and it is urgently required that schemes to tackle the problems should be taken. To effectively address the problems as such, this paper aims to propose sustainable utilization and management scheme of fishing ground through classification of fishing ground surrounding Wangdol-cho as one area which is less than 50m deep, measuring $13.66km^2$ and the other, permission fishing area of Gill Net fishery, measuring $347.23km^2$. The analysis shows that, for the water area less than 50m deep, implementation from a short-term perspective includes autonomous management fishery by gill net and trap fishery. For the permission fishing area of Gill Net fishery, implementation includes limit on fishing period, real name system of fishing equipment and limit on fishing equipment. Implementation from a medium and long-term perspective includes limit on scuba diving, designation of underwater sightseeing zone, sea farming, facilities of surveillance, adoption of approval system for the permission fishing area of Gill Net fishery and introduction of report system for fishing.

  • In order to establish order in fishing industry by cracking down on illegal fishing vessels effectively, it is an essential requirement to identify marking such as the name of fishing vessel and a port of register more easily. Accordingly, it is quite natural that markings on fishing vessels should be marked clearly in an appropriate size on an appropriate site in order for them to be distinguished on the air such as from planes as well as on the sea. Actually, when examining marks such as the name of a vessel which are operating in the country, marks of most fishing vessels are too small as they cannot be distinguished with the naked eye even very closely. There is no coastal fishing vessel which marks the name of fishing vessel on the upper part in order to distinguish it from planes. Fishing vessel law generally which regulates the basic laws about shipbuilding regulates marks on fishing vessel, and fisheries law only regulates sign boards of fishing vessels. Problems and improvement of the marking system on fishing vessels suggested by this paper are as follows. First, in order to contribute to establish order in fishing industry, it would be desirable to tighten standards in fisheries law besides the fishing vessel law. Second, it is difficult to distinguish marks such as the name of a vessel as relevant laws allow fishers to make such marks too small. It is necessary to set the standard for marks larger than those regulated by the international treaty. Third, the relevant laws do not regulate a letter form of marks. Therefore, it becomes a factor to make small marks hard to be distinguished more. It is necessary to decide a clear letter form. Fourth, there is insufficient detailed international standards about the marking system. It is necessary to regulate a detailed standard.

  • Korean fishery wage system has been evolved with the different titles. However, Since the law of fishing crew was enacted in 1984, the fishery wage system has been established as a rate system, which is a legal term. The present rate system in practice shows various contents and modalities, depending on fisheries and regions, but the fisheries of large trawl cooperative employ a rate system of fixed plus rate wage. However, such change did not transform basically the properties of pure rate scheme. As well known, fishing vessel owners face an awful lot of difficulty in managing and controlling effectively the production process because fishing activities are carried out in the seas remote from the land. Thus, it tend to be inevitable for vessel owners to employ a rate system to induce fishermen's positive motivation for promoting productivity and saving operating costs. However, the rate system has worked out as a driving force, which induce an increase in production more strongly under the expansion of vessel numbers and power and the keener competition of fishing activities. Even though the control mechanism of fishing instruments are well established, fishermen become naturally to have an incentive to increase their fishing effort for maximizing production since they are able to raise their shares by maximizing the quantity harvested. Thus, as far as the rate system exists, fisheries administration may have much difficulty in realizing its fishery management goals only through vessel reduction and fishing gear regulations. Also, under the rate system fishery management authority may be in face of a serious dilemma between the spontaneous rate system and vessel reduction policy. If the realistic aspect of the rate system is recognized and resource restoration and profit promotion are main policy goals, it is necessary to develop effective ways to control vessel owners' and fishermen's production-maximizing motives at an appropriate level. From this point of view, it seems reasonable to introduce TAC system by species or by fisheries into the existing fishery system. The research results suggest that if the fisheries administration could understand clearly the spontaneous fisheries wage system, it would know the norm of TAC and the basic reasons for illegal fishing activities and thus it would be able to develop and implement more realistic resource management policies.

  • This paper is the result of a comparative analysis of crew members' workloads using the EMG and OWAS methods according to the fishing process before and after the improvement of the operating system of the experimental vessel, with the aim of improving operational efficiency and safety work of coastal improved stow net fishing vessels. The target crew members were three people with at least five years of experience on board the same fishing vessel as the experimental vessel. After improving the operating system, such as installing a power block crane and two capstans, change the location of the ball-roller, the time required for setting and hauling work decreased (p < .01), and the evaluation results by OWAS showed that the overall workload for setting and hauling net work decreased. The results of muscle activity analysis showed a decrease in lashing anchor work (p < .01) in the case of hauling net and in anchor dropping work in the case of setting net (p < .001). It is judged that the use of ball rollers in net handling has been reduced; consequently, work safety has been improved.

  • The reduction of fishing grounds due to the establishment of EEZ system among China, Japan and Korea together with the depletion of fish resources by pollution of waters and successive reclamation projects along the east and the south coastal lines has made many problems in coastal communities including the decrease of population, the deepening aging phenomenon in the fishery society and the fall of relative income level compared with those of rural and urban residents. Especially, the income level of a fishing household is 90%. of a rural resident and 70% of a urban resident. The income of a fishing household consists of 55% of fishing income, 20% of a agricultural source, 20% of income from non-fishing areas, and 10% of transferred income. Compared with that of a Japanese fishing household which has more diverse income sources such as 62% of income coming from non-fishing areas through being hired in manufacturing firms, etc., that of Korean ones is highly dependent upon fishery and agriculture, so that the diversification of income sources is urgently needed, especially in non-fishing areas. This paper shows that as a model to upgrade fisherman's income level, firstly, it is necessary to enhance the value-added of fishing products through processing and new innovation of distribution process and, secondly, to promote tourism in fishing villages. To ascertain this model, a questionnaire survey to fishermen was carried out and showed that they expressed a strong support for the increase of income by the value-added process through processing and innovative distribution system and the active introduction of tourism in fishing villages. A case study on Gosan cooperative in Jeju was also introduced to identify the rationale of the suggested model and this study proved the validity of the model again. Conclusively speaking, to level up the fisherman's income requires the value- added activities through the introduction of product processing and new distribution system together with the introduction of marine tourism in fishing villages.

  • The purpose of this study is to suggest improvement directions and strategies for the minimization of ex-post damage and prevention of the generation of derelict fishing gear which lead to decreased fisheries resources and deteriorated marine ecosystem through ghost fishing and damaging spawning and growth grounds. Current problems related to derelict fishing gear in Korea are lack of reliable data on the generation amount of derelict fishing gear, absence of life-cycle monitoring and management system, insufficient supports for derelict fishing gear collection programs and R&D investment in environmentally friendly fishing gear, etc. Thus, this study suggests three basic improvement directions to prevent the generation and minimize the damage of derelict fishing gear. Such improvement directions contain more detailed strategies such as establishment of fishing gear management law and life-cycle management system, strengthening entry regulations on fisheries causing serious ghost fishing problems, increased supports for R&D investment and dissemination of bio-degradable fishing nets, and promotion of voluntary agreements among competing fishermen's groups.

  • The sustainable reduction of the fisheries resource is keenly raised an urgent problem of the fisheries policy in Korea, China and Japan. Then, 3 country, Korea, Japan, China, have established various system for fisheries resource management. Among these systems, qualitative fishing regulations have been commonly established. For example, its have been enforced to the prohibited fishing region, fishing period, fish size, net size, specified fishing methods. Also, different fisheries resource management policies have occasionally enforced by each country. For example, the prohibition of free sale and free possession has been established in Korea and Japan, but not China. And, In Korea, It has been enforced uniquely to entry system far fishing license number ana sea farming project for coastal fishing grounds by national government. The entry system for fishing license number has been enforced in Japan too, not national government, but local government. Nevertheless these three countries have put good system for fisheries resource management above mentioned, real enforcement has been not operated well. For efficient management on same fisheries, next problem will have been solved. First, it has to be guaranteed to transparency on the fisheries management, which is considered the priority problem on the fishing regulation. For reason, although efficient system is established in each country, if feasibility of the system was not trusted, mutual effort like that is very difficult to gain desired results. Then, each country has to establish transparency on the fisheries statistics and administration. Second, it has to be adjusting on the criteria or level of fisheries resource management. Now Korea, Japan and China have different criteria or level of fisheries resource management, for, example, prohibited fish size and prohibited fishing net sine. To solve above problems, three countries need to deeply discuss together. Then fisheries resource co-management scheme should be established in same fishing ground.

  • We analyzed risk factors of coastal gillnet fishers during fishing process and considered work safety measures to reduce safety accidents during fishing using a UWB (ultra wideband) based positioning system. The static position accuracy of the UWB based positioning system was 45 cm. When entering a port, there is a risk of falling overboard. When casting a net, there was a risk of falling overboard due to being hit by fishing gear or guards, or getting caught in a buoy line or sinker line. When hauling a net, there is a risk of getting caught between fishing gear and net hauler, and the risk of musculoskeletal disorders due to repetitive work over a long period of time. Most safety accidents during work on fishing boats are blamed on human errors of the fisher and skipper, but safety accidents occur due to a mixture of mechanical and equipment factors, work and environmental factors, and management factors in addition to human errors. Therefore, the 4E were presented as countermeasures against the 4M, which are causes of safety accidents, and the proposed measures were used to identify risk factors for operation process, comply with work safety rules, and ensure the wearing of personal protective equipments. We need to reduce safety accidents during work by making it part of our daily routine. These research results can be used in the future for optimal placement of fishing gear and fishing nets in other coastal industries where safety accidents occur frequently.
