The goal of this paper is to set the research and development (R&D) strategic plan of Honam Sea Grant (HSG) program which is to secure the base technologies for the success of Jeollanamdo's policy projects in the area of maritime and fisheries. HSG's mission is to support science-based sustainable management, conservation and enhancement of Honam coastal and aquatic resources through research, extension and education. Firstly, 80 cases of Jeollanam-do's policy project and 48 cases of HSG's R&D project are compiled and classified into the five areas of maritime and fisheries. Secondly, typical key words are extracted from each five areas and assessed the inherent meanings of each key words using quarterly segmented meaning allocation techniques with 'intended for practical use', 'intended for theoretical use', 'intended for future', and 'intended for current'. Then, we proposed R&D strategic plan based on the evaluation results and, it's practical use is also discussed.

Because of the radical changes in the domestic and foreign economic circumstances Koreaa fisheries is confronted with difficulties. Along the end of the UR marine products of other nations are rushing into Korea. Also migration of labor to other industries and rise of wage level in Korean fisheries deteriorate managerial conditions. But in Korea which has little natural resourses fisheries is still more important. That is \circled1 creating job opportunites \circled2 increase of income \circled3 supply of foodstuffs and animal protein \circled4 acquisition of foreign currency \circled5 enlargement of domestic market for industrial products \circled6 development of other interrelated industries \circled7 rational use of domestic resourses \circled8 diversification of population and production activites \circled9 contribution to balanced growth of national economy by the developing regional economy. These roles of fisheries in national economy mentioned above are to be excuted forward. In spite of the radical change in the economic circumstances at the end of the UR fisheries if crucial in Korea as a industry. For this our fisheries is to be made to compete with foreign fisheries. Through the cheap price and high quality our fisheries must be came to compete with foreign fisheries and meet the people's needs for marine products. For this it is necessary to maintain high productivity and competitive power. Now with the exception of a portion of the deep - sea fishing, our fisheries is generally paltry, Especially inshore fishery which is the main stock in our fisheries is very paltry and so productivity and competetive power are very low. So to develop our fisheries which has s comparative disadvantage active polices that follows below are to be promoted on a large scale. \circled1 improvement of structure \circled2 augmentation of productivity in fishing ground by making fisheries resourses \circled3 enlargement of finantial and monetary assistance \circled4 effective administration of fisheries cooperative union \circled5 activation of R&D etc These polices which need to be scientific and comprehensive are very valuable. Especially without making fishieries resources we cannot expect economy of scale, promotion of productivity and development of fisheries. And we do also endeavour to gather the results of the study and investigation about fisheries domestic and foreign and do ceaselessly put these to practical use systimatically.

In this study, the Bayesian state-space model was used for the stock assessment of the Blackfin flounder. In addition, effective measures for the resource management were presentedwith the analysis on the effectiveness of fisheries management plans. According to the result of the analysis using the Bayesian state-space model, the main biometric value of Blackfin flounder was analyzed as 1,985 tons for maximum sustainable yield (MSY), 23,930 tons for carrying capacity (K), 0.000007765 for catchability coefficient (q) and 0.31 for intrinsic growth (r). Also the evaluation on the biological effect of TAC was done. The result showed that the Blackfin flounder biomass will be kept at 14,637 tons 20 years later given the present TAC volume of 1,761 tons. If the Blackfin flounder TAC volume is set to 1,600 tons, the amount of biomass will increase to 16,252 tons in the future. Lastly, the biological effectiveness of the policy to reduce fishing effort was assessed. The result showed that the Blackfin flounder biomass will be maintained at 13,776 tons if the current fishing efforts (currently hp) level is set and maintained. If the fishing effort is reduced by 20%, it will increase to 17,091 tons in the future. The analysis on the economic effect of TAC showed that NPV will be the lowest at 1,486,410 won in 2038, 20 years after the establishment of 2,500 tons of TAC volume. If the TAC volume is set at 2,000 tons, NPV was estimated to be the highest at 2,206,522,000 won. In addition, the analysis on the economic effect of the policy to reduce the amount of fishing effort found that NPV will be 2,235,592,000 won in 2038, 20 years after maintaining the current level of fishing effort. If the fishing effort is increased by 10%, NPV will be the highest at 2,257,575 won even thoughthe amount of biomass will be reduced.

This study aims to propose the policy direction for agriculture and fisheries heritage system in Korea. The agriculture and fisheries heritage system is defined as traditional agricultural activity systems and landscapes which should be preserved, sustained and handed down and evolved from the co-adaptation of a community with its cultual, agricultural, biological environment. The key characteristics of the agriculture and fisheries heritage system of Korea are as follows; Firstly, this system designates software and hardware factor of heritage in integrative manner. secondly, this system seeks to preserve and utilize such heritages simultaneously. Thirdly, this system intends to strengthen the role of people in rural area. Fourthly, this system makes use of new engine of growth in agricultural community. This system is designed by comparing and reviewing several related domestic and foreign systems including FAO' GIAHS.

It has been recognized, virtually from the time of its inception, that fisheries economics, like other aspects of resource economics, should ideally be cast in capital-theoretic terms. The fish population or biomass can be viewed as a capital stock in that, like conventional or man-made capital, it is capable of yielding a sustainable consumption flow through time. This study is to introduce the optimal control theory which was extended from the theory of calculus of variations into the study of former static theory of fisheries economics started by Gordon (1954). The optimal control theory eliminated the inadequacies of the classical techniques to a large extent. From this point of view, this study, on the base of Schaefer model, summerizes most of major results achieved so far, but does so in a manner such that the links with capital theory are made transparent. This study explores two sets of problems. The first concerns the optimal approach to the equilibrium stock, i.e. the optimal investment policy. The second set of problems arises from the relaxation of the highly restrictive assumption of autonomy (i.e. the assumption that the parameters are independent of time), then concludes the relaxation of linearity assumption together with the complexities caused by that.

The Comprehensive Measures for a soft landing of Household Debts affecting the credit service of Fisheries Cooperative (FC) have been known to the public in June 2011. Its essential points are as follows: 1) Abolition of Tax-free Regulation, 2) Set limit of loans, etc. per person, 3) Introduce leverage regulations for credit-specialized financial sector i. e. FC, 4) Gradually strengthen loan-loss reserve requirements for card-loan and other credit loans. However, the Financial Policy Measures seem to pay no attention to the Cooperative's Values, Principles and Identity. In this paper, emphasis is be placed on the task of the regulators i. e. Financial Services Commission and Financial Supervice Service to lift the Financial Measures negatively affecting the operation of fund of FCs, and on the establishment of Cooperative identity in order to further develop FCs.

This paper first makes a survey of fishing household economy which possess fishing boats under 10 gross Tons by a questionnaire, and makes a comparative study of major indicators of fishing household economy between Korea and Japan, and finally suggests some policies for the fisheries management. Major indicators are the status of fishery household members, number of fishing boats which possess, fisheries incomes, fishing household incomes, side business incomes of fishing household, disposal incomes, living expenses, sufficient degree of living cost, average propensity to consumption and so on. Some policies for improvement in fishing household incomes are suggested in the paper as follows: ⑴ Form a policy similar to a project aiming for increasing the income of fishermen so that the side business income will also increase. ⑵ The point of view in tracing origin of low productivity. ⑶ It has drawn up a plan to encourage saving after analyzing the cause of high propensity to consumption. ⑷ The paper is aimed to collect basic statistical materials for fisheries administration.

Although scientist have been reporting recently that changes in ocean environment influence the species composition, movements, and growth of fish in Korea waters. Previous studies on fish vulnerability owing to climate changes are insufficient to explain the effect of fluctuating ocean environments on fisheries ground. In this study, we suggested a method for the assessment of fisheries sensitivity to various factors in ocean environments in Korean waters. To evaluate the fisheries sensitivity, catch data (Chub mackerel, Hairtail, Common squid, small yellow croaker) from National federation of fisheries cooperatives in Korea (1991-2017) and oceanographic data from Korea Ocean Data Center (KODC; 1960-2017) were normalized using the z-score method. Thereafter, the fisheries sensitivity was calculated using the difference between the catch data and the oceanographic data. Finally, the fisheries sensitivity was evaluated based on evaluation grade ratings. Result revealed that in the south sea, variability in catch data was obviously higher than environmental fluctuation (evaluation grade 1), indicating that catch variability in response to environmental change is most sensitive in the south sea among Korean waters in 2017. These results would be helpful for fishery management and policy for sustainable yield in Korean waters.

This study is aimed to analysis the fishery consciousness of the fishermen in Kyungbuk province. an issue for the study may be used on activating device of fisheries high school. So, the data were collected from a fishermen living at the city of Pohang in Kyungbuk province. The treatment of materials are classified by age, level of a school career and by working career. This research evaluated percentage to the frequency of responses to each question and carried out $\chi^2$. The statistically signigicant level account for p<.05 and made use of SPSS 10.0. The conclusion of study were as follows; First, fishermen have little understanding for fishery consciousness, therefore there was needed public activities and life long education. Second, in order to solve the difficulties of fisheries villages, governmental financial support have to be presented, It is showed that economically, culturally, and financially, govermental policy should be devised for the purpose of emerging from backwardness of fisheries villages. Third, large portions of economic value should be allocated to fisheries villages by improving fisheries structure. Actually, lower incomes haves have burdened fisheries villagers with more debts. More years of being engaged in fisheries have resulted in more debts. People in fisheries villages regarded incomes as the most important among factors in their selecting fisheries as a job. If they earned more money in fisheries village than in metropolises, people on fisheries villages would choose the fisheries an their jobs. Naturally, there will prove to be an increase of number of persons engaged in fisheries. Also, thinking of fisheries as dangerous and heavy should be corrected into the new image by improving work environments and mechanization.

This paper is aimed to analyze how to evaluate the choice of optimal management measures and level of control in fisheries management under the costly and imperfect management system by comparing with costless and perfect management system that is commonly assumed in the analysis of fisheries regulations. Fishermen would set the level of fishing efforts at the point where the marginal fishing profit for fishing effort is equal to the marginal level of fine under costly and imperfect management system. Therefore, under the case where the marginal fishing profit is higher than the marginal level of fine, the level of fishing efforts would be made at the point which is higher than the level of fishing efforts made under costless and perfect management system and is not a point where the economic profit is maximized in regulated fisheries. From this conclusion, the fishermens avoidance activities against regulations as well as the level of control in fisheries management substantially have an influence on the choice of fisheries management instruments. According to the analysis of optimal fisheries management policy, the economic profits in regulated fisheries are determined by the level of fisheries enforcement costs and total fishing profits, in which as enforcement costs increase the economic profits decrease. In addition, the economic profits vary in response to the level of control in avoidance activities. That is, as avoidance costs decrease, the economic profits increase. The determination of optimal level of control in fisheries management should be made at the point where the marginal regulation costs are equal to the marginal profits from regulated fisheries, in which marginal regulation costs are different according to the type of management measures. And the level of profits changes in response to different levels of avoidance activities. The management measure that can maximize the difference between the marginal regulation costs and marginal profits from regulated fisheries should be chosen as an optimal fisheries management instrument.
