  • 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 objective of this study was to estimate physical properties and fishing performances of net twine with improved PBS copolymer resin (Bio-new), the existing PBS/PBAT blending resin (Bio-old) and commercial Nylon (Nylon). The tensile strength of Bio-new monofilament was equal to Bio-old and the elongation of Bio-new was about 6 % higher than that of Bio-old in wet condition. The physical properties tests were carried out to estimate breaking load and stiffness in dry and wet conditions, respectively. In the results, the breaking load of Nylon netting was the highest whereas the elongation of Bio-new was 1.4 times higher than that of Nylon netting in wet condition. The breaking load of Bio-old netting was about 9.2 % higher than that of Bio-new netting. However, the elongation of the Bio-new netting was about 3% higher than that of Bio-old. The stiffness of the Bio-new compared to Bio-old was improved about 34 % in dry condition and about 32 % in wet condition. The filed experiments of the fishing performance were conducted with three kinds of drift nets with different netting materials in the coastal sea of Jeju. The each experimental drift net made of different materials showed the similar fishing performance. Bio-old drift net yielded less catches of small sized yellow croaker than other drift nets. The netting materials affected the fishing performance and length distribution of catches in the drift nets.

  • The purpose of the study is to analyze the status and trend of less favored condition of fishing village in Korean island regions using the census of agriculture, forestry and fisheries. The less favored condition was measured as the difference in accessibility to major services and in fishery sales and resident infrastructure, applying the difference-in-difference method and propensity score matching method respectively. The result shows that access to major services has improved in island area between 2010 and 2015, implying that related policies such as the island comprehensive development project have been successful to some extent. However, some educational facilities, cultural facilities, and health facilities still have low inaccessibility and fishery sales are also significantly lower than in general area. This suggests that it is necessary to maintain related policies like the direct payment of fisheries.

  • The analysis of the written verdicts in recent five years was conducted to obtain preventive measures of collision between fishing vessel and non fishing vessel. As a result, a collision much happened in offshore trap for fishing vessel and below 5,000 tons of small and medium class for non fishing vessel. A person involved in a marine accident occupied 68% in sixth class deck officer and small boat operator for fishing vessel and 29% in third class deck officer for non fishing vessel. 90% of the collision happened in a underway by operating state and 84% in sight of one another by visibility state. The systemic radar training was required since 47% of the collisions was occurred on the condition of radar operation in fishing vessel. The main cause of poor lookout was a intensive fishing and poor lookout on movement by radar for fishing vessel and one man watch system and no recognition of one another by radar for non fishing vessel. This result is expected to contribute for the decrease of collision.

  • This study describes the result on PV system for evaluating the performance of small fishing boats. Photovoltaic system with 200 watts power generation facilities on the 3-ton fishing boat was carried. Load test was performed on the condition that the work lamps lit during night operations. As a result the performance can be used for more than two hours at 60 watt work lamps. The load test was performed on the condition that fishing vessels are on the cruising condition at sea. The solar power systems have been investigated as a power generation efficiency of about 36.55%. Additional tests show that the power generation efficiency is difficult to expect a maximum of 50% or more. Fuel consumption of fishing boats by installing a solar power system is reduced. Also the PV system is useful for the verification of their availability for fishing vessels as well as the satisfaction of the fishermen. The results for the durability of the photovoltaic device is acceptable, including a solar panel, controller and the performance exhibited no breakage in the harsh marine environment or failure so far. The installed PV system was confirmed that the durability with at least 2 years.

  • This study analyzed the multivariate impacts of subsidies on the sustainability of fish stock using a dynamic bioeconomic modeling and fisheries resources economic approaches for understanding impacts of a subsidy on the sustainability of a fish stock. According to the results of analysis, the conclusion of former studies is true only there are imperfect control of fishing effort and enforcement under management rerime and under open access. However, if there are perfect control of effort and enforcement, the subsidies do not give any negative impacts on the sustainability of fish stock. Further, if even so-called bad subsidy is also provided necessarily in response to the condition of fishing industry and the characteristic of fishermen, it can give positive impacts on fishing income by which fishermen can improve their fishing condition.

  • As the UN Fish Stocks Agreement has come into effect since 2001, the actual enforceable management on fish stocks in high seas has started. The Regioanl Fisheries Organizations (RFOs) have emerged as management bodies with a real responsible right to manage fish stocks. RFOs establish a strong and strict management rules providing a fishing right only to member countries and preventing all fishing activities from fishing vessels of non-member countries. In addition, RFOs have an own allocation way of fishing opportunity in their waters so that they can prevent the depletion of fish stocks. It is investigated that deep-sea fisheries have a negative impact from strengthening of RFOs' management right. As the amount of catch is reduced by the control of fishing vessel's activities, the level of fishing revenue becomes low. Moreover, as fishing costs such as oil, fishing fees, labor cost increase significantly, the condition of fishing business is getting worse as a result. In order to gain a fishing right for deep-sea fishing vessels in RFOs waters, there is no other alternative way but become a member of RFOs which are relevant to our fisheries but not joined.

  • In order to offer data about fisheries resources management and prediction of catch on large purse seine fisheries, the fluctuation of the fisheries condition and distributions of fishing ground for mackerel were analysed with monthly catch data for 1990.2009. The overall catch has decreased to about 70% since 1997, with approximately 70% of the mackerel (Scomber japonicus) catch and monthly fluctuations showing a similar pattern. Monthly distribution of fishing ground is like distribution of mackerel in large purse seine fishery. The main fishing grounds are near Jeju Island and the Yellow sea with the main fishing season existing between October to December. The catches fluctuations and distribution of fishing ground were related to the effect of regime shifts. Therefore, in order to prediction of catch on large purse seine fisheries should be studied these relationships.

  • As one of the most popular outdoor leisure activities in the world, recreational fishing has a lof of significant meaning in terms of social, economic, and cultural views. However, both not considering an indiscreet fishing activity and environment and not thinking our next generation, fishing circumstance has been deteriorating more and more. Unlike Korea, most advanced countries enact various recreational fishing management and support policies in order to keep sustainable recreational fishing and develop eco-tourism through cooperation with government, fishing industries and civil organizations. This paper consist of the following contents. First, the study attempted to investigate how to operate management system of the recreational fishing dividing into in - land fishing and sea fishing respectively. And it exhibits issues and troubles of the realities of recreational fishing management and related fishing laws and ordinances in Korea. And then, it examines various fishing management schemes in representative advanced nations; U.S., Germany, and Japan. Also, it analyzes the advantages and disadvantages of respective recreational fishing management systems; market - based license system, qualification - based management system, and self- regulatory based management system. In addition, after these three systems are adopted to Korea's recreational fishing condition, we analyzes whether respective management systems fit or not. As a result of this, the optimal management for recreational fishing is the participatory self - management scheme in Korea. Finally, in order to support recreational fishing promotion and encouragement, issues and complementary policies with respect to recreational fishing are introduced.
