  • This study aims to estimate the smallest size of mature individuals that can be exploited. Fish samples of Coryphaena hippurus were collected from Kalinaun fishermen's catches in the Molucca Sea. They were sexed, then the fork length (FL) and maturity stage were recorded. Results showed that C. hippurus in the Molucca Sea had a sex ratio of 1:1.94 (p < 0.05). Males had a length range of 499-831 mm FL and females were in the length range of 481-813 mm FL. Size at first maturity was estimated as 529 mm FL for males with a range of 475-588 mm FL and 405 mm FL for females. This study provided basic information for future management needs of the dolphinfish, especially in the Molucca Sea.

  • 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.

  • 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 regional differences between urban and rural areas make many diverse differences. There are various differences between urban and rural areas such as economic gap and cultural gap. There is also a difference between urban and rural areas in accessing and utilizing information. The purpose of this study is to clarify the relationship between the information gap and the income gap among farmers and fishermen groups, where information gap is considered to be more serious than other groups. In other words, we tried to examine whether the information gap between farmers and peasants affects the income gap. The purpose of this study is to analyze the relationship between informatization level and income of farmers based on the information gap index and survey results conducted every year by the government. The results show that there is a statistically significant positive relationship between the informatization level of farmers and household income. In addition, the trend of the regression coefficient is positive, suggesting that the government needs various informatization policies to increase the informatization level of farmers.

  • Reduction of fishing grounds, which was caused by the recent fisheries agreements between Korea, Japan, and China, Is Increasing the important of coastal fisheries. Korea's coastal fisheries, however, need special management measures owing to the following problems. First, there are too many fishing fleets even though fisheries resources are continuously decreasing. Despite the fact that some of the fishing vessels have been scrapped, there still remain too many vessels and especially approximately 27,000 vessels increased during 1997-1998. Second, as the condition of fisheries resources changed radically, many fishermen are fishing by methods which they were not permitted to. These fishing methods cannot be legally supported and so there is a huge gap between the system and the reality, Third, two or three licenses are given to each coastal fishing vessel because a single license cannot give sufficient income, but some of these are formally acquired. So under such circumstances, efficient management of fisheries is impossible. Fourth, absence of demarcation among regions and industries is causing frequent conflicts and there are concerns about the decreasing fisheries resources due to competitive fishing practices. Therefore, considering the above mentioned problems Korea's coastal fisheries management should be developed as the following: First, new licenses should be limited while expanding the buy-back program. The government is currently planning to limit new licenses by introducing the fixed license number system in coastal fisheries but is somewhat passive about the buy-back program. Second, fisheries management which is based on self-regulation should be established. In order to increase the effect of fisheries management, the fishermen should decide by themselves the fish and fishing methods they would be exploiting and directly regulate them. Third, it is necessary to integrate the licenses of coastal fisheries. Since coastal fisheries management through the license system has distinct limitations, it is preferable to unify risking licenses and let the fishermen decide specific matters on their own. Finally, it is necessary to establish boundaries among the regions and industries. Joint fishing areas among regions(cities and provinces) should be established and fishing in other areas should be permitted on condition of paying the required fees. On the other hand, it is also necessary to permit coastal fishing only within certain distances.

  • The observer program is being utilized In various fishing areas and fisheries internationally and nationally due to the its expected effectiveness in fisheries management and the collection of bioeconomic data necessary in fisheries management policy. The timely gathered data by observers play substantially a major role in decision-making fisheries policy such as the change in management measures, the application of season closure and area closure and etc. The expected effectiveness of the observer program In fisheries management, generally mentioned, is that it would lead to the increase in stock size from which the level of harvest would consequently increases. This study is aimed to analyze this tentatively expected effectiveness of the observer program in fisheries management. The changes in stock size and the level of harvest over time are analyzed under the observer program assuming the fishermen bear the cost of the observer program by investigating the change in fisherman's fishing activity under the observer program and by combining this changed activity with the biological model. The level of fishing efforts of fishermen was decreased from the results of the increase in fishing cost caused by the observer cost and the decrease in catchable stock size restricted by observers. This reduced level of fishing efforts enables stock size to increase over time and therefore, the expected level of harvest increases as time goes on. Another benefit under the observer program is to reduce management costs from the fact that fishermen are responsible for the cost of the observer program and the avoidance cost of fisherman responding to the fisheries regulation could be eliminated from the surveillance of observer. Therefore, it may possible to accomplish the cost-efficient fisheries management policy.

  • In order to prevent the maritime accident, all seafarers who work on fishing vessels over G/T 20 tons are required to undergo the basic safety training by the Seafarer's Act. 45% of domestic crews have boarded on the fishing vessels. However, the fishermen have been trained in accordance with the STCW(International convention on standards of training certification and watch-keeping for seafarers) Convention. But safety training courses for seaman do not reflect on the safety equipment and the limitation of the fishing vessel in the training contents which is organized in accordance with the merchant ship by STCW convention and code. Most of the fishing vessels are small fishing boat of less than G/T 80 tons. Small fishing vessels are operating with only a minimum of safety equipment that has been defined by the fishing vessel safety equipment standard. Due to the safety training that does not fit the situation of the fishing boat, the level of satisfaction by the crews onboard is low for the training. Furthermore, there is a difficulty in achieving the goal of safety education. In order to carry out the safety training that is suitable for fishermen, it is required to provide appropriate standards for the safety education of workers of small fishing boat, by understanding the current state of the domestic fishing vessels. The purpose of this study is to define the aforementioned problems and to provide the standard for the safety education of fishermen. In order to complete the purpose, the research team has conducted a analyzation for registered domestic fishing vessel and safety equipment 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.

  • It is widely known that farmers and fishermen group is typically alienated from information. In this regards, it has become a national policy to help them get benefits from using PC. Therefore, this study investigates the effects of PC competence on their life satisfaction by using the 2017 report on the digital divide. Especially, we are focused on analyzing mediating role of Internet service usage. Empirical analysis with public database showed that PC competence has a positive effect on life satisfaction. Internet service usage also revealed a mediating role between PC competence and Internet service usage. Implication for policy makers is that government needs to exercise PC competence level of farmers and fishermen, and their ability to utilize Internet service for the sake of improving their life satisfaction level. We recommend future research with hierarchical linear model to measure the effect of regional differences.

  • This study is aimed to develop an improved shellfish dredge vessel considering the increase of the fishing safety and welfare of fishermen in Jeonnam province. We visited five fishing village societies in Korea, and conducted field surveys and survey questions to investigate the current status. In order to solve the problems presented by the investigation, a general arrangement of the improvement vessel was written and adopted after meeting between the fishermen and research team, and calculated the initial stability in five loading conditions by using the Napa program. As a result of field surveys and survey questions, the existing vessel have buoyant materials under the bow and the warp pass through the wheel-house. In addition, most fishing equipment and nets are concentrated on a narrow stern, making it difficult to work efficiently. According to the survey, fishermen also responded that operation of casting and hauling is very inconvenient. The fishing equipment of the improvement vessel was rearranged, the size of the wheel-house and the crew room was increased, and we secured a basic welfare space. As a result of the initial stability test, the stability criteria of the fishing vessel were satisfied in all loading condition.
