  • This paper studied the feasibility for utilization of the automatic fishing information recording system, which stores and manages navigational information and fish catch results of a fishing vessel in a portable storing device, in order to help promote the systematic management of fishing information by offshore and coastal fishing vessels. Position accuracy was within 10 meters on the position accuracy experiment using GPS module. Characteristics of navigation according to the navigation, anchoring and fishing operation showed the difference of navigation track information for GPS, and fishing possibility of fishing boat could be estimated through the analysis as the utilization result of system for the large pair trawl and large purse seiners. In particular, it is impossible to provide false positional information by arbitrarily operating the system, and it may be possible to present the factual results of fish catch by date, fishing ground, and fish species by comparing the fishing information with fish catch. Such contents are considered to be useful as basic data for the management of fisheries resources.

  • Fisheries policies are diversifying, including welfare programs for fishermen, revitalization of earfish and villages, and support for the sixth industrialization of fishing villages. In response to these policy changes, the purpose of this study is to categorize the fishing village fraternity, which is a local community, a fishery production organization, and a basic unit of a fishing village, and compares the characteristics of each type A number of indicators were selected by collecting data on the Categorization and evaluation of fishing villages fraternity and the statistical geographic information service. A number of indicators were extracted as representative factor variables using the principal component analysis, and then cluster analysis was performed to categorize the fishing village fraternity. This study was the first to attempt a comprehensive approach to revitalize the fishing village economy by using not only demographic and social characteristics, industrial and economic characteristics, but also regional characteristics. The characteristics of each type of fishing village fraternity find its significance in that it provides basic information that can be used in policy decisions. In order to strengthen the sustainability of the fishing community in the future and contribute to the sustainable development at the national level, the development of sustainable fishing village fraternity development indicators and follow-up studies on fishing village regeneration strategies will be needed.

  • The purpose of this study is to investigate the fishery perception and recreation fishing demand level of coastal waters ranch with the case in Tongyeong city's Bijin-do Yongcho-do, Juk-do. The study conducts a survey of 27 fishermen and 113 recreation fishing tourists from September 26 to November 21, 2016. The major results of this study are as follows. First, the survey of fishery perception level suggests that the increase of fishery resources by Tongyeong-si coastal waters ranch project contributes to the rising income of fishermen, decreased fishing cost, and increased the number of tourists. Second, the survey of recreation fishing tourists's demand level suggests that a beautiful view, fish populations, kindness of residents, fishing point information, charter information, and the convenience of transportation are highly praised and highly regarded. However, links to nearby tourism, lodging facilities, and food information that can increase the income of fishermen is poorly praised. Therefore, this study suggests that a careful marine policy with fishery resource creation should be followed for marine fishing village tourism consumer's benefits in order to increase fishing village's income.

  • We collected AIS information on fishing vessels operating near Jeju Island, and analyzed appearance density of the Chinese fishing vessels and inferred the movements of the fishing grounds. AIS information was received from October 16, 2016 to October 16, 2017 and stored on a hard disk through a program called AisDecoder. Unauthorized fishing vessels within the Exclusive Fisheries Agreement Zone (EFAZ) operated near the EFAZ boundary, and the frequency of appearance of fishing vessels were high in the middle waters of Korea and Japan, 252 and 250 fishing zones. Chinese fishing vessels authorized to enter appeared scattered outside the Prohibiting Fishing Zone of the Large Trawlers (PFZLT), and the closer they were to the PFZLT boundary, the higher the appearance density. And the appearance of Chinese fishing vessels with a speed from 0 to 3 knots was mostly outside the EFAZ, showing high density in the waters close to the boundary between Korea and Japan. On the other hand, within the EFAZ, the frequency of appearance of Chinese fishing vessels was also low and scattered. The appearance of Chinese fishing vessels with a speed from 3 to 5 knots mostly shows some variability within the EFAZ, but the frequency of appearance was high and the density was high. The seasonal appearance of Chinese fishing vessels in the waters south of Jeju Island appeared in the southwest in the autumn and then moved south and southeast of Jeju Island in the winter, and in the spring and summer. They were considered going to other fishing grounds without fishing in the waters south of Jeju Island.

  • 수협의 어선조업정보는 국가 공식 통계가 가지고 있지 못한 위치별 조업정보를 가지고 있다는 장점이 있다. 위치별 조업정보는 해당 지역의 어업피해보상, 자원가치 산출 등을 추정할 수 있어 국가통계자료로의 가치가 매우 높으나 어업인들의 자기 정보의 노출에 대한 기피로 인해 신뢰성이 떨어지는 단점을 지니고 있다. 본 연구는 유용성분석을 통해 이러한 수협의 어선조업정보의 활용을 위한 방안을 제시하고 위치별 조업패턴의 특성을 분류하여 해구별 유사성의 정보를 산출을 목적으로 하였다. 분석결과 수협의 어선조업정보는 정부 생산통계대비 어획량의 약 33% 수준이나 유용성 분석에서 그 패턴과 상관관계가 밀접해 위치별 패턴파악에 유용한 것으로 나타났다. 이를 바탕으로 대해구별 2단계 군집분석을 통해 어획량, 조업일수, 조업척수에 대해 각각 최적의 군집을 구분하고 이를 종합하여 8개의 군집으로 패턴을 구분하였다.

  • Engaged in trawling in limited fishing grounds with a number of fish schools could cause collisions between fishing vessels. Therefore, providing accurate maneuver information according to the situation could be regarded as essential for improving seafarers safety and fishing efficiency as well as safety of navigation. It is difficult to obtain all maneuver information through sea trial tests only, so a method through empirical formula is necessary. Since most empirical formulas are developed for merchant ship types, especially the characteristics of hull shape parameter like CbB/L and dCb/B etc. are clearly different between fishing vessels and merchant ships, this could occur estimation errors. Therefore, in this study, the authors have selected target fishing vessels and merchant ships and analyzed the characteristics of hull shape parameter according to the ship types. Based on this analysis, the empirical formula developed for the merchant ship type has applied to the target fishing vessels; it has verified through the turning motion simulation that the estimation error could be generated. In conclusion, it is necessary to include the characteristics of the hull shape parameter of fishing vessels in the empirical formula in order to apply the empirical formula has developed for merchant ship types to fishing vessel types.

  • This study is conducted to apply the insight of Johnson and Libecap(1982) to Korea's coastal vessel fishing. According to Johnson and Libecap(1982) the differences in fishing ability are largely attributed to acquired knowledge and innate skills. Since those skills are unlikely to be readily transferable assets, economic rents exist in the fishery, even under open access conditions. Therefore the paper tries to examine whether the acquired information from fishing experience and innate skill could also have an effect on catch variation of coastal vessel fishing in Kyung-Nam province. To do so, the paper is performing the analysis by establishing econometric model. Results show us that the acquired information from fishing experience have a significant effect on catch variation, but the innate skill does not.

  • 본 논문에서는 동해에 있어서의 오징어 채낚기어업의 조업위치선정에 필요한 해황정보인 표면수온, 중 하층수온에 주목하여 검토하였다. 표면수온으로 검토한 오징어 채낚기어업의 어장형성에 관해서는 각 어선이 조업시에 측정한 수온을 어해황속보와 대비해 보면 같은 표면수온에서도 약간 차이가 있었다. 그래서 조업위치선정에 있어서 중요한 해황정보인 조업시에 있어서의 표면수온을 사용하여 고찰한 결과 해에 따라서 해황상태가 달라도 조업척수가 가장 많은 표면수온은 대체로 $2^{\circ}C$ 범위내에 들어간다는 것을 알았다. 그러나 중 하층수온에 관해서는 선단의 각 어선이 측정하고 있지 않다는 것과 근해관측이 200해리 수역내에서만 행해졌다는 것으로부터 한정된 시기에 대해서만 검토한 결과 6월 및 7월 상순에 있어서 신나천현선단(神奈川縣船團)의 조업해역에 있어서의 50m층 수온으로 보면, 난수역과 냉수역 사이의 $10{\sim}12^{\circ}C$에서 어장이 형성되었고 그후 극전선부근의 $5{\sim}8^{\circ}C$의 해역으로 어장이 이동하는 것을 파악할 수 있었고, 연안역에서는 극전선 남쪽의 난수역의 50m층 수온이 $10{\sim}12^{\circ}C$의 해역에서 어장이 형성된다는 것을 알았다.
