  • The main purpose of this study is to analyse economic feasibility of low-carbon-oriented gear for anchovy boat seine. The results of benefit/cost analysis showed that use of the low-carbon fishing gear is economically feasible. Considering the fuel saving and relatively low $CO_2$ emission by reducing the resistance of gear, net present value by such type 1 gear improvement was estimated about -2,490 ~ -1,580 million won with the benefit-cost ratio 0.81~ 0.88. And net present value by such type 2 gear improvement was estimated about 6,540 ~ 7,780 million won with the benefit-cost ratio 1.79 ~ 1.94. Development of lowcarbon trawl gear would render significant contributions to reducing $CO_2$ emission in fishing operations and lead to reduce fishing costs due to fuel savings.

  • This study raises the question about why do many international fisheries organizations or regional fisheries agreements come into existence, sustain, and develop prior to the internationally recognized institution such as United Nations Convention on the Law of the Sea(UNCLOS). In oder to solve the problem, I will investigate the characteristics of fisheries as renewable resources and propose the collusion model where it is based on the cost-benefit analysis. Especially, if once a fooall large number of fishing is implemented, they are immediately depleted. Consequently they are extinct and no longer exploitable. Thus each interest nations or participants will be better off if they are cooperative and will be worse off if they are competitive or noncooperative in a resource management. Therefore, many of the internationally recognized fisheries institutions and agreements have been made and developed in these days.

  • The aims of this study are to estimate the optimal vessel reduction scales and these direct economic effects of coastal and offshore fisheries in the Republic of Korea. To estimate respectively optimal fishing efforts of individual fishery by species in coastal and offshore fisheries, we adopted appropriate fishing power of each species published by National Fisheries Research and Development Institute and also considered biological and socio-economic factors such as the bycatch rate, the profit rate, the efficiency of resource use, the average age of fishing vessel, the intention of vessel reduction, and the annual changes in vessels by other factors. The direct economic effects of the optimal vessel reduction in coastal and offshore fisheries based on maximum sustainable yield and 2/3 maximum sustainable yield was calculated by a cost-benefit analysis. This study showed that optimal reduction numbers of vessels engaged in coastal and offshore fisheries were 4,431 and 374 vessels and the direct economic effects in coastal and offshore fisheries were about 371.7 and 569.4 billion won and these NPV and BCR were 111.7 billion won and 1.65 and 342.6 billion won and 4.97 respectively.

  • This paper analyzed that the economic effectiveness of the artificial fish reef project in the Tae-an Marine Ranching. Benefit-cost(B/C) model used to indicate the effects of economic valuation. B/C model is based on the sub-models which are Benefit Cost Ratio(BCR), Net Present Value(NPV) and Internal Ration of Return(IRR). First, the Sum of Incremental Benefit and Cost for total vessel by year in Artificial Fish Reef Area(AFRA) estimated 2,381 million won. And then, using 5.5% discounting rates and the survey data, the sub-models showed economically feasible in the all of analysis and analyzed the results as follows. BCR is 2.66, NPV is 28,014million won, and IRR is 22.78%. In conclusion, these results indicated that the artificial fish reef project in Tae-an Marine Ranching would be increase the income of fishermen as well as fish biomass.

  • The main purpose of this research is to analyze economic feasibility of biodegradable sonw crab gill net model project. The results of benefit/cost analysis show that use of the biodegradable gear is economically feasible. Assuming that the rate of gill net lost is 5 percent, net present value was estimated 311,898,282-590,533,375won, benefit-cost ratio 1.816-1.923 and internal rate of return 7.96-10.59%. The development and diffusion of biodegradable fishing gear appear to make a significant contribution to fisheries resource conservation and marine ecosystem protection. In addition, biodegradable gear production firms may have a good opportunity of exporting it to other coastal states, depending on the progress of WTO subsidy negotiation.

  • The purpose of this study is to estimate the economic value and productivity achieved through a reduction in fishing vessels engaged in coastal and offshore fisheries. We found that the value of increasing catch by types in offshore and coastal fisheries was about 17,338 billion won. To examine the economic value, a cost-benefit analysis was applied. This is based on the total cost of vessel reduction (4,576 billion won) assumed to be invested equally each year for five years. BCR and NPV with a discount rate (5.5%) were used to compare the profit of fishery activities in offshore and coastal areas. The model results showed that the NPV and BCR in offshore and coastal fisheries was 5,522 billion won and 2.340 respectively.

  • Though modern banking organs were established in Korea with the Kanghwa Treaty as a momentum, the benefit of financing at that time, which was mainly given to merchants and industrialists and traders, was extremely limited to the fishermen. The fishermen who were out of favor with the benefit of financing of modern banking organs were forced to rely on high interest loans, a category of usury capital, issued by the middlemen (the Kaekju) who lent them the deficit of their necessary funds. The fact was that in the field of fisheries the middlemen who issued usury capital played the leading part in fisheries financing of the Late Yi Dynasty. The middlemen, however, sqeezed a part or all of surplus products and on occasion even necessary products out of the fishermen by means of outward compulsion of economy. Moreover they put the fishermen further in trouble by putting-out system. In order to keep on with the production of aquatic products, the fishermen with little capital and no property established the antinomic rotations with the middlemen whose disadvantageous terms they were inevitably to accept. Thus the middlemen who did business with the fishermen exercised their authority over them, securing a strong activity foundation in the field of fisheries. But the traditional form of the Kaekiu was transformed and gradually declined in the field of fisheries according as the market rules were proclaimed in 1914.

  • The purpose of this study is to propose, firstly, the definition of marine health tourism and empirically to analyse the effect of benefit sought and brand equity on visit intention of destination as marine health tourism. This study utilizes the PLS-SEM method in order to measure the overall model fitness level and statistical significance of all paths in proposed research model. As a result of the analysis, benefit sought factor like nature has a highest positive effect on brand equity(image and perceived quality) and also, on visit intention via brand equity. Specially, this study measures the non-linear of all the paths and shows the statistical significance that the more high health factor as benefit sought is, the preference for quality brands is more steeply. In addition, the measurement of the moderating effect of gender variables shows that female is the most sensitive than male on the path from health benefit sought to brand quality among all the paths. However, the definition of marine health tourism in this study is proposed according to the characteristics of a particular area. In this vein, the definition is needed to generalize more through follow-up study.
