Offshore wind power development has been promoted in countries around the world to cope with global warming. Despite its many advantages, offshore wind power affects the marine environment during construction and operation. As a result, the reduction of fishing areas, changes in the habitat of marine animals, damage to fishing gear, and impeding the safety of fishing activities are occurring. If the offshore wind power generation project is carried out, a fishing damage investigation is nescssary. There are only four fishing damage investigations related to offshore wind power, which are being conducted similarly to the existing fishing damage investigation related to offshore construction. Therefore, this study reviewed and analyzed the report on fisheries damage investigation related to offshore wind power conducted in Korea and suggested problems and improvement measures accordingly.

For an effective management of fisheries resources, we need fisheries informations necessary for the establishment of reasonable fishing effort and TAC distribution. We carried out fishing research using trammel nets in the coastal sea of Susan-port(Yangyang, Gangwondo, Korea) and Hupo-port(Uljin, Gyeongbukdo, Korea) and analyzed fishing power variation of the fishing gear in terms of species composition, condition and so on for both sites. A total of 29 species were caught with most dominant species of Hippoglossoides dubius followed by Pseudopleuronectes herzensteini, Lophius litulon and Alcichthys elongatus in Susan. The total number of species caught in Hupo was 37 species with most dominant species of Todarodes pacifius followed by Lophius litulon, Hexagrammos agrammus and Pseudopleuronectes herzensteini. CPUE of Susan fishing area per trammel net was 12.74 fish and 2.00kg on average, while it was 6.80 fish and 2.27kg on average for Hupo. The fishing power index for both sites was 1, placing the two fishing grounds in a same level.

Lots of fishery stocks are overexploited and the overcapacity exists in Korean fishing fleets. One of the reasons is technological development, which increases the efficiency of the vessels continuously. The analysis was conducted to identify the change of fishing power index to develop the vessel and gear technology that may have improved the fishing efficiency of the offshore large powered purse seine fishery from 1960s to 2010s. Gross tonnage and horse power per fishing vessel was increased annually. Fishing gear material was changed to the knotless webbing to settle faster. Fishing equipments was modernized and supply rate was also increased. Therefore the relative fishing power index in the offshore large powered purse seine fishery increased from 0.4 in 1970 to 1.0 in 1980, to 1.5 in 2000 and to 1.6 in 2010, but the rate of increase slowed down gradually. The results are expected to contribute to reasonable fishery stock management.

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 government has promoted the local fishing port construction project since 1972 for conquest of the crisis of the fishing village by withering of a fishery, the improvement in fishermen's living environment and quality of life, and promotion of fisheries. In order to estimate the local fishing port construction project objective and synthetically, and to grope for the method proposal of system establishment of the project, the monitoring survey was carried out. The monitoring survey was classified into the program and the performance monitoring. The program monitoring was carried out in order to investigate the project fit for the inhabitants of a fishing village. The performance monitoring was carried out in order to investigate the development latent powers, fishery latent powers, tourism latent powers of a fishing village, rural settlement conditions, etc. using various statistical materials. Since investigating the measured value before executing a policy was not completed, the project effect was compared with the measured value of other areas. According to the local fishing port construction project, the development latent powers, fishery latent powers, and tourism latent powers of the fishing village where the project was undertaken improved greatly, and income of the fishing village increased greatly. As a result of comparing project fit in order to evaluate the project, the project fit of the local fishing port construction project area was higher than the non-project area. Desirable method proposal of monitoring survey was established and the method for raising the efficiency of monitoring survey was extracted.

Among the towns of GyeongJu and SamCheok on which I have surveyed about their amenity resources in 2010, I chose 5 towns that are close to the Eastsea to analyze the data and to devise how to revitalize fishing villages. And the results are as follows. 1. Although Yangbuk-myeon is geographically located to have all the aspects of fishing village, farming village, and mountain village, the resources utilized are mainly that of mountain village. There is need to utilize actively historical amenity resources like Munmudaewangreung of Yangbuk-myeon. 2. The use of amenity resources of Yangnam-myeon is centered on farm and mountain village. But if they utilize amenity resources of fishing villages of Eupcheon-port's neighborhood, it would be a big help for the revitalization of Yangnam-myeon which is depressed. 3. The fishing mackerels on boat of Gampo-eup Jeonchonri is a successful example of utilization of fishing village's amenity resources. However, there is need to utilize amenity resources of farming and mountain villages that are near to Gampo-eup, so it can attract visitors to stay longer. Particularly, the fishing villages of the East coast must develop 4 seasons program connecting the amenity resources of neighboring farm and mountain. 4. Geundeok-myeon is a town where they made the amenity resources of fishing village into tourist attractions. But considering the wide gap between Geundeok-myeon and neighboring fishing, farming and mountain villages that cannot get the advantage of development, there has to be some inducement in policy so every town can be developed evenly. 5. After analyzing how the towns utilize the amenity resources to make them tourist attraction, it is shown that Geundeok-myeon of SamCheok is the best town which is using fishing village's amenity resources well, and Yangnam-myeon and Yangbuk-myeon of GyeongJu are scarcely using them. About types of tourist attraction, the programs with scenic view of fishing village, with water-sport, and with Eco-experience are needed to improved.

Korean fishing boats have had appropriate hull forms for the safety, stability and convenience of fishing ability. However, Korean fishermen are recently concerned about the resistance performance and speed of Korean fishing boats, because the prices of fuel oil are gradually risen, also the exhausting of fish resources and the demand of high speed fishing boats are increased. Therefore, the necessity of the study on the improvement of resistance performance for Korean small coastal fishing boats is gradually increased. This study compares the hull form characteristics of Korean fishing boats with those of Japanese fishing boats, and the hull form of a representative Korean fishing boat is modified. From the modification of the hull form parameters for the Korean fishing boat, the improvement of resistance performances is evaluated. Moreover, the increase of resistance performances is also achieved from the modification of local characteristics for the hull form of the Korean fishing boat. A computational method and ship model tests in towing tank are used for the conformations of the improvement of resistance performance.

We conducted a questionnaire survey to analyze the current status of the coastal composite fisheries, as well as the improvement point in designing a new type coastal composite fishing boat suitable for Korean fishing environments from April to August 2017. The questionnaire composed of 20 questions about the features of the coastal composite fishing boat and fishing work. The survey sites were selected to cover all parts of the country by considering the geographical position. The significance testing for the response results was accessed by ${\chi}^2$ test and ANOVA. The results revealed that more than half (59.1%) of the fishermen operated one day per voyage and operating alone topped with 22.5% in the number of crews, followed by 2 persons (20.3%) and 5 persons (22.1%). The navigation devices had a high rate of installation and GPS plotter ranked first in the devices. In addition, fish finder ranked first in fishing equipment, followed by net hauler. The most inconvenient work that they felt during the fishing operation was fish handing at 49.8% and other general fishing works like setting and hauling line, deck cleaning accounted for about 25%. The hardest work was the accident by ropes wrapped around propeller and the engine trouble came in second. The most inconvenient facilities to the present design of fishing boat was wheelhouse (76.7%), followed by fish hold (38.5%), and deck (35.1%). Furthermore, inconvenient points related to the movement of fishing gear, noise and vibration of engine, slippery deck and small fish hold exceeded 50%.
