  • Experimental fishing was carried out to compare and analyze catch characteristics of shrimp beam trawl in a fishing area and a non-fishing area during the period of fishing season and off-fishing season in the coastal waters of Geoje. A commercial fishing boat (4.99 tons) was used for the test fishing. The amount of total catches were 14,654g in the fishing area and 12,359g in the non-fishing area, shrimp catches of non-fishing area were much greater than that of the fishing area during the period of off-fishing season (June and August). However, total catches were 27,670g in the fishing area and 33,004g in the non-fishing area, shrimp catches of fishing area were bigger than that of non-fishing area during the period of fishing season (October and December). On the results of the study, catches characteristics between fishing area and non-fishing area showed the reversed results for the period of fishing season and off-fishing season.

  • The fishing ground surrounding Wangdol-cho is not only overexploited by the littering of dilapidated fishing net and equipment, but also by fishermen's overfishing, surpassing optimum fisheries resources. In addition, increasing fishing efforts (number of fishing vessel and fishing net, etc) contribute to the deterioration of fishing ground, and it is urgently required that schemes to tackle the problems should be taken. To effectively address the problems as such, this paper aims to propose sustainable utilization and management scheme of fishing ground through classification of fishing ground surrounding Wangdol-cho as one area which is less than 50m deep, measuring $13.66km^2$ and the other, permission fishing area of Gill Net fishery, measuring $347.23km^2$. The analysis shows that, for the water area less than 50m deep, implementation from a short-term perspective includes autonomous management fishery by gill net and trap fishery. For the permission fishing area of Gill Net fishery, implementation includes limit on fishing period, real name system of fishing equipment and limit on fishing equipment. Implementation from a medium and long-term perspective includes limit on scuba diving, designation of underwater sightseeing zone, sea farming, facilities of surveillance, adoption of approval system for the permission fishing area of Gill Net fishery and introduction of report system for fishing.

  • This study aimed to estimate the economic value of the recreational fishing in the Jeonnam marine ranching area as a part of the total socioeconomic evaluation of the Jeonnam marine ranching program. A travel cost method was applied to the estimation of economic value of the recreational fishing in the Jeonnam marine ranching area and input variables included annual fishing trip days, average travel cost per trip, average catch amount, monthly income, marriage, age, and personal perception on the marine ranching program. In the analysis, due to its characteristic of count data, both poisson model and negative binomial model were used. Model results indicated that a negative binomial model was statistically more suitable than the poisson model as the overdispersion problem occurred in the poisson model. All signs of the estimated parameters were estimated as previous studies showed. Based on the results, the economic value per trip of the recreational fishing in the Jeonnam marine ranching area was estimated to be 145,000 won and the annual total economic value of the recreational fishing in the Jeonnam marine ranching area was analyzed to be 2,514,000 won. In addition, the change of total value by catch rate showed that the economic value could be increased by 180,900 won as the catch increased by one kilogram.

  • 부산 해운대구에서 사하구에 이르는 부산의 중심지역에서는 도시화의 진전 속에 어촌은 사실상 소멸하였으며, 인구밀집구역에 둘러싸인 17개 어항들이 주변지역과의 부조화 속에 방치되거나 고립되어 있는 상태이다. 그러나 이러한 도시화지역 내부의 어항은 해양도시로서의 아이덴티티를 부여하는 존재이며 그 활용여부에 따라 어항 자체 뿐 아니라 주변지역의 가치를 고양할 수 있는 잠재력을 가진 사회경제적 자원으로 삼을 수 있다는 것이 필자들의 기본적인 생각이다. 본 연구에서 우리는 중부산지역의 어항들을 대표적인 '도시형 어항'으로 정의하고, '도시'와 '어항'의 공존과 조화의 방향을 모색코자 하였으며, 이를 위해 중부산지역 17개 어항들의 어업생산기반과 주변환경 및 어항정비수요를 조사하고 어업인들과 지역주민들의 의견을 취합하여 도시와 어항의 조화로운 공존을 위한 도시형 어항정비의 중장기적 방향을 설정하는 것을 주된 목표로 하였다.

  • The fishery compensation by marine spatial planning such as routeing of ships and offshore wind farms is required objective data on whether fishing vessels are engaged in a target area. There has still been no research that calculated the number of fishing operation days scientifically. This study proposes a novel method for calculating the number of fishing operation days using the fishing trajectory data when investigating fishery compensation in marine spatial planning areas. It was calculated by multiplying the average reporting interval of trajectory data, the number of collected data, the status weighting factor, and the weighting factor for fishery compensation according to the location of each fishing vessel. In particular, the number of fishing operation days for the compensation of driftnet fishery was considered the daily average number of large vessels from the port and the fishery loss hours for avoiding collisions with them. The target area for applying the proposed method is the routeing area of ships of Jeju outer port. The yearly average fishing operation days were calculated from three years of data from 2017 to 2019. As a result of the study, the yearly average fishing operation days for the compensation of each fishing village fraternity varied from 0.0 to 39.0 days. The proposed method can be used for fishery compensation as an objective indicator in various marine spatial planning areas.

  • The purposes of this study were to identify the living environment in rural fishing area and to suggest checking methods for implementation performance. Rural service standard is the key factor of rural development in Korea. In 2012. The first Implementations of performance was announced. The results were presented to the unit by the City and the County. Because of Fishing villages exists as a unit by the haengjeongri. It is difficult to know the status of the fishing villages by the Rural service standard. In order to look for the actual conditions in rural fishing village it was investigated in the 100 Eochongye. The data used in the analysis is 577 questionnaires. Analysis showed that rural fishing areas were superior to general state of rural in the 8 items of rural service standard. Especially housing, transportation and health care sector in rural fishing area wes better than general state of rural. But Public safety and order is relatively poor. This is because Fishing village contains islands. Presenting to improve rural service standard based on the results of research. The items of rural service standard should be measured the actual residents' accessibility than opportunity of the public service, and after setting the rural service standard clearly related to the quality of life of residents in each sector. Accessibility aspects of the customer for the public services should be considered. Checking the performance for the unit by the City and the County should be replaced as a living zone in order to consider the facilities using nearby.
