Around the 1980s, with government's promotion and dissemination policies for FRP (Fiberglass Reinforced Plastics) of the government as a main material of fishing boats, approximately 97% of the entire fishing boats in Korea have utilized FRP until now. Nevertheless, diverse social and environmental issues have emerged due to the susceptibility to fire and the generation of substances detrimental to human health during the construction process of FRP fishing vessels. Especially, the high disposal cost and the limitation of recycling technology in the disposal process of FRP fishing boats have elicited attention to circular economy. This research intended to grasp the management status and problems of disposed FRP fishing boats in Korea, and to assess the level of competitive advantage of FRP fishing boats' recycling technologies of FRP fishing boats based on VRIO (Value, Rarity, Imitability, Organization) analysis through domestic and foreign management policies and related recycling examples. According to the survey of 161 respondents, including the industry, stakeholders and experts related to the collection, treatment and recycling of fisheries wastes, it was revealed that FRP fishing boats' recycling technologies of FRP fishing boats are at the level of 'unused competitive advantage' that satisfied the level of value, rarity and imitability, but not the level of organization.

Catches, CPUE, fishing season, disc width composition and fishing ground were studied to rebuild skate ray, Raja pulchra resource by the offshore longline fishery in Heuksan-do, Korea. Annual catches and CPUE of skate ray were increased from 2003 to 2010 (CPUE: from 2007 to 2010) continuously. The main fishing season of the skate ray was from December to next May. Disc width at 50% maturity for Raja pulchra by sex were estimated to be 65.83cm, 57.01cm by female and male respectively. The range of disc width was 22.3-112.0cm and the average disc width was 66.9cm, 60.0cm by female and male of Raja pulchra respectively during 2007-2010. Annual average of disc width of female skate ray was decreased from 2007 to 2010. The fishing grounds were formed from the coastal water off Hong-do to the coastal water off Gyeogyeolbiyeol-do, Korea. The center of fishing ground in October was formed in the northwestern coastal water off Gyeogyeolbiyeol-do and separated from that of the other months.

Although Korea operates various systems and policies for the management of fisheries resources, it is judged that a more systematic resource management policy is needed due to the continuous decrease in the production of coastal and offshore fisheries. In this study, the catch capacity was analyzed using the DEA technique for coastal and offshore fisheries. As a result, despite the decrease in the amount of fisheries resources and the number of fishing vessels, there was a trend of increasing fishing capacity. As of 2019, the total maximum catch of offshore fishery was estimated at 820,007 tons. The actual catch was 548,159 tons and the CU was measured to be about 66.8%, which was analyzed to be an excess of about 33.2% of the catch. The total maximum catch of coastal fisheries was estimated at 187,887 tons. The actual catch was also the same value and the CU was measured to be about 100.0%. Thus, it was analyzed that there was no excess in catch. For the management of fisheries resources, it is necessary to manage the fishing capacity. To this end, policies such as scientific TAC should be promoted as well as expanding the reduction of fishing vessels.

This study examines the significance and problems of the Fourth Amendment to the Fisheries Act, which went into effect in January 2023. Following the passage of the Aquaculture Industry Development Act, the fourth amendment to the Fisheries Act sought to reform the fisheries legislative framework, while also including significant changes. In particular, a number of new systems for managing fishing gear have been implemented, and local governments now have some autonomy in fisheries management, which has allowed for adjustments to be made to meet the needs of the fishing industry and changes in socioeconomic situations. However, as independent legislation for each fisheries sector continues, the subject of regulation under the Fisheries Act, as well as the Act's position as a basic legal system, has been continuously reduced, overshadowing the Act's objective. As a result, a full-fledged assessment of changing the legislation's name in the future is required, as well as addressing issues such as the lack of difference in the legislative purpose clause and the necessity for further revision of the definition clause. Therefore, any future revisions to the Fisheries Act should aim to overhaul the existing framework, including fishing licenses and permits.

In this study, we developed a thermoelectric generation system for coastal fishing boats that allows for a high-density arrangement of thermoelectric modules, verified the improvement in performance by conducting comparative analysis between field test results and results from previous studies. The developed thermoelectric generation system was installed in a 3-ton gill-netter to analyze the engine revolutions per minute and energy production per day for each fishing process over a period of 20 days. From the experimental results, the maximum electric energy generated was 207.1 Wh, the minimum was 53.93 Wh and the average electric energy was 129.98 Wh. In accordance with the increasing of the engine r.p.m., the maximum electric production was 183 W at 1,500 r.p.m. It was approximately 80.5% of designed capacity, 227.2 W. Considering the result in the earlier research was 50.7% of designed capacity, 115.8 W. It was improved by 30% compared to the earlier one. The fishing operation was classified as departure, fishing and arrival. From the result on production analysis of electric energy, the composition of energy was 63% in fishing, 19.5% in departure and 17.5% in arrival. The electric energy production per unit hour was 42.8% in arrival, 32.9% in departure and 24.3% in fishing.

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.

A fishing lamp is fishing gear to gather fish in the night. But the cost of oil which is used to a light fishing lamp, goes significantly up to almost one hundred million won for 50 tonnage vessels and forty million won in case of vessels less than 10 tonnages. This cost has almost taken 30.40% of total fishing costs. As oil price increases, the business condition of the fishery gets worse and worse. Therefore, it is very urgent to develop an economical fishing lamp, to solve the problem of fishery's business difficulty. This research aims at developing a fishing lamp for squid jigging fishery and hairtail angling fishery using the LED, which has excellent efficiency and durability. One fishing lamp has about 160Watt capacity and five fishing lamps are installed one aluminium panel in which sea water flows to emit generated heat from LED to outside. Developed fishing lamp lights to an effective direction of jigging and angling operation. This fishing lamp can be controlled to light the direction of fish shoal because the aluminium panel can be controlled to up and down direction. The wave length of fishing lamp has white and blue color. White color light is to gather fish shoal of horizontal direction and blue color light is to gather fish shoal of vertical direction. After development of this fishing lamp, 60.110 units are established on the boat, and operated fishing. Consequently, in the case of squid jigging, spent energy was reduced to 39%, in the case of hairtail angling, 68% of spent energy was reduced. And the catch was more than another boat.

It is important to understand the factors in which fishing village experiences have on family relationships. The purpose of this study is to derive the variables related to the family stemmed from the analysis of previous studies, and to find and present common factors that specifically influence the fishing experience in the family relationship. Through this, we intend to find it out in addition to the visible results such as income and experience, it can be an effective policy as a means to improve family relations through mutual efforts and understanding among families in promoting fishing-related policies. As a result of the analysis of the study, two common factors that the fishing experience had on family relationships were extracted. The first common factor is 'mutual effort,' which results in trying for each other's emotions, communication, understanding, and unity. The second common factor is 'mutual sharing' so fishing experiences are generally related to each other in family relationships. It can be seen as a result of sharing the memories, pleasures, and bonds of the people.

It is undeniable that IUU Fishing are threatening so many legal fishermen' economic livelihood, negatively impact on conservation and protection of the fishery stock and ecosystem itself. Especially, negative impact of IUU Fishing resulted from the increasing fishery activities on the high seas. The Korea case of Coastal and Off-shore Fisheries, difficulties in conserving and controlling the fishery stock was brought about. Simultaneously, it is the fact that there are so many damage such as the reduction of fish Stock management program's effect, dissatisfaction of legal fishermen, over-exploiting of fish stock. Related with this kind of problem, FAO had adopted "International Plan of Action to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing(2001)". From this reason, Korea also needs to make actual efforts to prevent IUU Fishing. i.e. each nation should develop Korea action plan by Feb. 2004 and impliment it, report on implementation toward FAO. This Paper will review the definition of the IUU stipulated by "International Plan of Action on Illegal, Unreported and Unregulated Fishing" and study Korea cases of the IUU fishing. Finally, the analysis of Korea's implementation will be done, centering around the contents stated on the International Action Plan. The significance of this paper is to grope the political countermeasures against international movement of the IUU fishing prevention.

The purpose of this study is the impact of national fishing port investment and typhoons on fisheries disaster damage. The dependent variables were the amount of damage to fishing ports, fishing boats, fisheries enhancement, external facilities, mooring facilities, functional facilities, fishing port and typhoons. The analysis period is from 2002 to 2018. Since the error term is in a simultaneous correlation, it was efficiently estimated by analyzing it with a seemingly unrelated regression (SUR) method. As a result of the analysis, external facilities have not significance to all models. Investing in mooring facilities increased the amount of damage to fishing ports for five years. Investing in functional facilities reduced the amount of damage to fishing ports and aquaculture over five years. Typhoons have significance to all models, and the amount of damage increased every time a typhoon occurred. Based on these results, as the influence of typhoons increases, it seems necessary to establish preventive measures. Timely investment and maintenance to enable the role and function of national fishing ports are considered important.
