  • Marine recreational fishing is one of the most popular outdoor leisures and the number of people who are participating is sharply increasing more and more because of the increasement of their income and demand for marine leisure. However our ecosystem is inevitably facing marine environmental deterioration and overfishing. That is because marine recreational fisheries resources are common property resources which can be catched by anyone not willing to pay for them except their private costs as commercial fisheries. Also fisheries resources unlike other resources are renewable resources and have a critical zone. That is, having a possibility of severe depletion may result from high discount rates used by private exploiters. This paper is focused on that marine recreational fishing license system which is adopted in most advanced countries such as Canada and U.S. and included in deterioration. And money obtained by license fee should be spent for more improvement fishing culture and welfare for marine recreational fishers.This system can lower the high rates of discount and be useful to become a sustainable marine recreational fishing industry.

  • Internal waves and internal tides occur frequently along the eastern coast of Korea. During the spring-tide period in April 2003, the East Korean Warm Current (EKWC) flowed near the Korean East Coast Farming Forecast System (KECFFS; a moored oceanographic measurement system), creating a strong thermocline at the intermediate layer. Weakened stratification and well-mixed water appeared frequently around the KECFFS, with duration of approximately 1 day. The results suggest the following scenario. Baroclinic motion related to the internal tide generated high frequency internal waves around the thermocline. The breaking of those waves then created turbulence around the thermocline. After well-mixed water appeared, a current component with perpendicular direction to the EKWC appeared within the inertial period. The change in stratification around the KECFFS locally broke the geostrophic balance as a transient state. This local vertical mixing formed an ageostrophic current within the inertial period.

  • Main target of fishing policy was enlargement of fishing catches in Korea after 1960s. This has caused sustainable decrease of the amount on the fisheries resource. In the result, fishing managements in Korea have suffered from aggravation of management. In this research, it is estimated the technical efficiency on Korean Off-shore Stow Nets Fishery that was made publication by Farrel in 1957. According to the analysis, Its were excessive to the gap of technical efficiency among Korean Off-shore Stow Nets Fishing boats. The gaps were excessive not only among each fishing managements but also by tonnage class and by region. Then we can recognize we need the change of Fishing Policy. That is, we should change for main target of fishing policy from enlargement of fishing catches to the policy of Price. And we should consider the supply of standard tonnage boats and specialization of fisheries by regions.

  • Information on maritime boundaries is essential to manage ocean and fisheries effectively in the era of the UN Convention on the Law of the Sea. With various information regarding to maritime boundaries analysed and reviewed, maritime boundaries are mainly divided into two categories such as international and domestic boundaries and also sub-divided into two aspects such as administrative and other boundaries. After clarification of boundary information, the geographical natures of boundaries, for instance datum, projection, line types, are reviewed. The Geographic Information Systems (GIS) is used for the establishment, management and utilization of boundary information due to its strong function in database, analysis, visualization, etc.

  • This research examined the transformations of the fisheries relations between Japan and Russia since the establishment of the Exclusive Economic Zone (EEZ) system. The author reviewed the transformations with investigation on mutual fishing access to EEZ including salmon & trout catches. The Japan-Russia fisheries relations have evolved through multiple developmental stages, which include mutual fishing access to EEZ, the reductions of a fishing quota to balance catches of the nations, provision of financial and technical support, and a payment system of EEZ fishing access fee. The Japanese salmon industry also has done similar practices, continuing to catch salmon and trout in the Russian EEZ. Additionally, Japan and Russia have attempted to develop joint fisheries projects and to assure fishing operation safety around Kuril Islands. The case of Japan-Russia mutual fishing access shows that a country that has authority over crucial fisheries resources tends to establish specific conditions of mutual fishing access so that it maximizes its national interest. Thus, this case gives us implication what could be future directions of Korea-China-Japan multinational fishing access. The principle of same number of fishing vessels and quantities of catches has worked in existing mutual fishing access to EEZ among Korea, China, and Japan. However, it is expected that a nation that is endowed with abundant fisheries resources would limit counterpart's fishing access to its EEZ. Therefore, Korean fisheries administration should prepare for all possible situations like a dramatic cut in fishing quota and the termination of fishing access. International fisheries cooperation and payment of fishing access could be viable options for such a situation.

  • During the past 100 years, Korean fisheries management policies have enforced the license system, it is the most typical regulation system in Korean fisheries. Even now, it has caused resource management failure, it has also invited economic inefficiency and inequity. Accordingly, the Korean government has recently introduced the self-regulatory management system for fishermen with the TAC system. These systems are one of the most market-oriented regulation systems in fisheries management systems. It is defined as regulatory policy tools other than regulations with command and control approach. It is also called “alternatives” which is composed of regulatory alternatives and non-regulatory alternatives. The self-regulatory management system and the ITQ system are cooperative-based co-management between government and fishermen as an alternative management strategy ; it is gaining the increasing attention to improve the effectiveness of fisheries management in Korea. It is expected not only to positively improve function in fisheries regulation, but also to decrease inefficiency in fisheries policies. However, these systems have many problems. The monopolization of rent is one of the typical examples. As solutions for the problem in the aspect of fishery management, fisheries policy is need of approach to industrial organization. For instance, Contestable market theory is one of the good theoretical background, it mean that market is able to free entry and free exit. Thus, fisheries management carry out policies such as revitalization of the used market of capital goods in fisheries, organize of the self-regulatory management group. Conclusively, as the exploiters and managers, fishers and the government should put emphasis on improving economic efficiency so that fishery would grow as an industry that contributes to the increase of social welfare, and the change to that direction will be the only way for our fisheries to preserve its importance.

  • This is a study of a long term project to encourage the Korean fishing industry. It seeks to supply a sound theoretical background in an attempt to liberalize the capital investment of the industry. However, the discussions developed in this thesis are based on, the existing world's fisheries resources, the possibility of their prospective cultivation, and the analysis of the evolution of Korean fisheries and fisheries organization. According to the reasults of the analysis ; out of the prospective world fisheries resources which are estimated at about 200 millions m/t the total yield per year is only about 70 millions m/t (1969), and Korea occupies only 850 thousands m/t. This therefore means that the Korean fishing industry allows much room for further growth. But the purpose of Korea's existing fishing industry organizations is entirely directed toword coastal fisheries and their functions never reache beyond the limit of off-shore fisheries. Thus almost 99% of the fisheries population engage in small scale fisheries along the coast line. The result is that the resource are almost exhausted by such over-exploitation. Being faced by this fact, it is of urgent necessity to modernize the management of fisheries as well as to encourage larger scale management of fisheries industries. This should be accompanied by the liberalization of capital investment. For this purpose this study also recommends the unification or annexation of small organizations to establish larger ones that will function for a larger scale industry. and further this study recommends that, in order to reorganize the existing fisheries organizations, a principle of selection should be applied in the areas of (1) maximum sustainable yields, (2) the possibility of forming an enterprise and (3) the maintenance of organization stability.

  • A characteristic of a region's environmental resources is the competitiveness of local agricultural products. This study explores methods of making locally produced agricultural products appealing to consumers. We looked at ways to appeal to consumers by using the image of environment resource and environment-agriculture product image congruence. The relationships of two dimensions of environmental image, perceived quality and purchase intention, are examined. From the results of the study, both the image of environment resource and environment-agriculture product image congruence have a positive effect on purchasing local agricultural products through perceived quality. This study tried to ascertain which of the two dimensions of the environmental image factor is more effective in terms of consumer appeal for local agricultural products. As a result, both the image of environment resource and environment-agricultural product image congruence are found to have a positive effect on the purchase intention of consumers through perceived quality. By comparing the paths of the two dimensions it is found that the method of appealing to consumers by using the environment-agriculture product image congruence is more effective. The results of this study present an effective method of making locally produced agricultural products appealing to consumers and suggest an effective strategic direction for selling local agricultural products.

  • Mercury is an element of special concern for human health. Measurements of total mercury levels in fish have been taken into consideration to assess risk. In this study, the Antarctic toothfish Dissostichus mawsoni was evaluated as a potential safe food source through measurement of total mercury contents. Total mercury concentrations in Antarctic toothfish ranged from $0.101{\pm}0.047mg/kg$ to $0.139{\pm}0.075mg/kg$. The total mercury concentration was significantly correlated with macroscopic values including total fish length, weight, gonadosomatic index, and maturity (P < 0.01 or 0.05). Furthermore, according to the risk assessment, the total mercury body exposure rate from Antarctic toothfish ranged from 2.125% to 2.847% of the Provisional Tolerable Weekly Intake. Therefore, the Antarctic toothfish could be used as a potential safe seafood source.

  • To measure the proximate composition of fisheries products and to evaluate their nutritional value, we collected individuals from 101 species from the east (Pohang), west (Gunsan), and south (Tongyeong) coasts of Korea: 51 fish species, 32 species of molluscan shellfish (Gastropoda and Bivalvia), 6 species of Cephalopoda, 8 species of Crustacea, and 4 other species. The proximate composition of fish was $75.3{\pm}5.0%\;moisture,\;19.1{\pm}2.7%\;protein,\;3.8{\pm}4.1%\;lipids,\;0.4{\pm}0.3%$ carbohydrates, and $1.4{\pm}0.3%$ ash. The proximate composition of molluscan shellfish was $79.1{\pm}3.2%\;moisture,\;14.2{\pm}3.2%\;protein,\;0.7{\pm}0.6%\;lipids,\;3.9{\pm}1.9%$ carbohydrates, and $2.1{\pm}0.4%$ ash. We observed clear regional variation in the lipid content of some fish species. Specifically, the lipid content of gizzard shad (Clupanodon punctatus) was highest in the autumn, while the lipid contents of red seabream (Pagrus major) and purple pike conger (Muraenesox cinereus) were highest in the winter. The daily average intake of the proximate composition through fisheries products consisted of 11.7 g of protein, 1.9 g of lipids, 1.1 g of carbohydrates, and 1.1 g of ash. The respective intakes of protein, lipids, and carbohydrates from fisheries products were about 19.3, 3.6, and 0.3% of the nutrient reference values set by the Korean Food & Drug Administration. Therefore, fisheries products playa very important role as a source of protein.
