  • Fossil fuel combustion during fishing activities is a major contributor to climate changes in the fishing industry. The Tier1 methodology calculation and on-site continuous measurements of the greenhouse gas were carried out through the use of fuel by the coastal and offshore gillnet (blue crabs and yellow croaker) and trap (small octopus and red snow crab) fishing boats in Korea. The emission comparison results showed that the field measurements are similar to or slightly higher than the Tier1 estimates for coastal gillnet and trap. In offshore gillnet and trap fisheries, Tier1 estimate of greenhouse gases was about $1,644-13,875kg\;CO_2/L$, which was more than the field measurement value. The $CO_2$ emissions factor based on the fuel usage was $2.49-3.2kg\;CO_2/L$ for coastal fisheries and $1.46-2.24kg\;CO_2/L$ for offshore fisheries. Furthermore, GHG emissions per unit catch and the ratio of field measurement and Tier1 emission estimate were investigated. Since the total catch of coastal fish was relatively small, the emission per unit catch in coastal fisheries was four to eight times larger. The results of this study could be used to determine the baseline data for responding to changes in fisheries environment and reducing greenhouse gas emission.

  • The present study is aimed at evaluating the economic effectiveness of Abalone, haliotis discus hanai Releasing Project(ARP) conducted in the fishing ground owned by a fishing village in Ulsan, Korea. The results were summarized as follows: First, an average ratio of released abalones in the total landing after releasing is shown to be 85.0%. Second, the recapture rate of released abalones is 46.8%, exceeding the recapture rate of BEP(Break-Even-Point), 22.9%. Third, it is evaluated that total economic effectiveness of the ARP is 6.7-6.8 times, net effectiveness is 2.2-2.3 times, and the NPV(Net Present Value) discounted by a 8% interest rate is 474, 635 thousand wons, indicating the project is profitable. Considerable parts of the positive results on the ARP are based on some beneficial conditions, including the selection of favorable releasing sites, best self-regulation system of a fishing village for preservation of seaweed facilities and continued activities for protecting small abalones and their rearing. These results imply that the success of the ARP would be primarily dependent upon the selection of releasing site and effective management system after releasing.

  • Faced with large scale of outdoor recreation resources and variety of demanders' desire, it would be necessary for the managers to estimate the values of individual attributes rather than a bundle of characteristics of outdoor recreation sites. By extending the Brown and Mendelsohn's (1984) approach we are able to estimate the beneficial effects of the improvement of individual attributes. Sampling 208 fishermen who visited 11 free fishing sites located in Daegu and Gyeongbuk, the functions of marginal willingness to pay for scenery and non-crowdedness were estimated. If 1 unit of scenery could be improved from its average value a fisherman, on average, would receive benefit of as much as 3,840 won. The average beneficial effect of the non-crowdedness improvement would amount to 2,220 won.

  • As offshore wind farms are developed, the importance of cooperation with stakeholders such as fishermen from the initial phase is gradually increasing. This study developed a methodology that can promote the involvement of fishermen in the site feasibility review process. The spatial scope is Gunsan City, which is establishing an initial offshore wind project strategy. A survey was conducted for representatives of 12 fishing villages on the location preference for offshore wind farms. As a result, fishermen suggested negotiable or absolute opposite locations by examining a local sea map. Location preference seems to depend on the degrees of vitalization of fisheries using vessels. This study shows that fishermen can have reasonable opinions according to the location, not unconditionally, in initial discussions on offshore wind power. Investigating stakeholders with various positions is essential, and adjustments are needed for conflicting points in the future.

  • In spite of the importance of a fishing industry, neither any terminology defined in details nor academic systems to educate the workers in the fishery were established in the fisheries social education. The fisheries social education was considered to be the practical area around the actual fields. Therefore, on-site education was very important. Accordingly, this study collected and analyzed theoretical basis of a social education and data on the rural adult education and examined the actual status of the fishing industry in Korea and fisheries extension services enterprise and fisheries developmental enterprise corresponding to the actual fisheries social education conducted in Korea. On the basis of these frames, this study summarized the direction for the progress of fisheries social education that has not been studied until now for the purpose of suggesting the future directions of the fisheries social education as follows; The recognition on the importance of fisheries social education and fundamental researches in the fisheries social education should be extended. The practical development of fisheries social education should be realized. Fisheries extension services enterprise should be evolved by fishermen. The abilities of instructors in the fisheries social education should be improved. The academic factors in the fisheries social education should be emphasized. Inter-disciplinary and multi-disciplinary approaches should be adopted. Various programs should be developed for the progress of the fisheries social education. The exclusive department in charge of the fisheries social education should be established. The information system for the fisheries social education should be secured. The industry, academic organizations and the organs should make cooperation. The fisheries social education should be provided by general social education institutions for the progress. The fisheries development should be deployed on the basis of environmental preservation. It is necessary to deploy the new fishing village movement like the Saemaul movement to the fisheries. The administrative and financial supports for the fisheries social education should be expanded. It is essential to cultivate the future fishermen for the international competitiveness.

  • The purpose of this study was to derive selection attribute of fishing experience villages, and to analyze the importance and performance on targeting experts and experienced tourists. Consequently, it could suggest implications for the guideline and the evaluation criteria of making fishing experience villages for the revitalization of eco experience tourism. Therefore, in this study, literature investigation and IPA analysis were used by Microsoft Office Excel 2010, SPSS 20.0. As a result, the 'variety of local foods and specialties' was the most urgent attribute to require intensive management strategy. And it is recommended to improvement about 'attributes related residents' because it were insensitived on the recognition by users. Satisfaction of 'appropriateness of coast' was the lowest, but the efficiency was quite high. Finally, not only 'the area of control' but also 'the area of influence' should be reviewed as an important aspects on developing the fishing experience village. The significance of this study is to derive selection attributes of making fishing experience villages for revitalization of eco experience tourism, and to suggest strategy directions based on IPA analysis result by experts and experienced tourists. But in this study, the site was limited to Gyeonggi-do, so it is recommended to expand further.

  • Fish school monitoring technology is utilized for various purposes, such as boat fishing and resource surveys. With advancements in information and communication technology, this technology has expanded its application to remote areas. Its significance has grown in fishing sites, particularly for improving the efficiency and cost-effectiveness of set-net fishing. Set-net fishing gears are not limited to coastal areas, but are also installed in inland and remote sea regions. Consequently, fishermen require technology that allows them to quickly transmit information about approaching fish schools and enables them to perform long-term monitoring. The development of remote monitoring technology for set-net fish schools must consider crucial design factors such as communication range, transmission speed, power consumption of information modules, and operational expenses. In this study, we developed a low-power remote monitoring module for set-net fish school based on WCDMA. The module was specifically designed to minimize power consumption, allowing for communication over long distances and extended operation times in set-net fishing applications. Furthermore, we developed a web server software application that enables remote access to fish schools and provides real-time weather information. The performance of the developed module was evaluated through set-net fishing site application and experiments with moving ships on the sea. The experimental results demonstrated that the remote monitoring system, consisting of the developed low-power remote monitoring module for set-net fish school based on WCDMA and a fish finder, had an average power consumption of 4.6 W, a maximum communication range of 22.84 km, and a data transmission and reception rate of 98.79%. The maximum fish school information transmission and reception rate was 97.26%
