  • 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.

  • To improve the fishing environment of Alaska pollack fishing ground of the East coast in Korea, lost fishing gear were recovered from June to July 1998, May 1999 and from July to August 1999 in the sea near Goseong, Gangwon province. The lost fishing gear was recovered by grapnel. As the results, the lost fishing gear, which was consist of gill nets and traps, was produced from fishing activities, whereas most of them was the bottom gill nets. The weight of lost fishing gears was gill nets of 1,170 t and traps off 4t. The recovered gill nets decreased 12.02 t per mile from 22.74 t, in 1998 to 10.72 t, in 1999. Recovery rate of lost fishing gear was low as 38% in 1998, 41.9% in 1999 and CPUE was 11.27 t/trial in 1998, 7.48 t/trial in 1999. The recovery of lost fishing gear in fishing ground by using grapnel was considered as a useful method.

  • 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.

  • This study is to contribute to income growth of fishermen by the common octopus fishery characterized in the Tando Bay on the southwest coast of Korea. This area is engaged in Longline fishing (301 persons), Shovel fishing (196 persons), Trap fishing (14 persons) and Torch light fishing (40 persons) in 2008. Population who is joined in the spring becomes main fishery target population of longline fishery in the fall because entering fishing ground in August, and is joined in the fall becomes main fishery target population of longline fishery in the spring because entering fishing ground in December. Average size of common octopus examined by longline 6.26cm, 5.82cm for Shovel fishing, 8.09cm for trap, and expressed big difference by fishery. It needs necessary various kinds of Octopus resource management actions and methods in continuous use. Specially, Fishing force increased by fishing automation system, so the reduction of fishing force is needed to increased by fishing force. Government support and fishermen's self-conscious of resource management is needed.

  • In the central Busan area from Haeundae to Saha, fishing villages are vanished actually in the progress of urbanization, and 17 fishing ports surrounded by urbanized area are left alone and isolated. But, we think these urbanized fishing ports are the very resource which grant the identity as the marine city and they have considerable potentials to enhance the value of neighboring community depending on the proper development of it. In this study, we defined the fishing ports in central Busan area as the representatives of 'urban fishing port', and tried to find the way of coexistence and harmony between 'city' and 'fishing port'. For this purpose, we investigated the fishery potentials, physical environments and development demands of 17 fishing ports in central Busan area, and composed opinions from fishing communities and neighboring inhabitants to set up the long term directions of urban fishing ports development for harmonious coexistence of city and fishing port.

  • 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%.
