  • 인간 활동의 증가는 새들의 서식 환경에 큰 변화를 가져왔으며, 번식과 생존에 직 간접적으로 영향을 미치고 있다. 특히 낚시를 비롯한 수상 레저 활동은 물새들의 번식 성공에 많은 영향을 주고 있으나 국내에서는 이에 관한 연구가 아직 미흡한 편이다. 이 연구에서는 남양호의 수초군락에서 번식하는 물닭(Fulica atra), 쇠물닭(Gallinula chloropus), 논병아리(Podiceps ruficollis), 뿔논병아리(Podiceps cristatus) 4종에 대하여 낚시 활동이 둥지 위치 선택과 밀도에 미치는 영향을 조사하였다. 조사 지역은 수초군락의 위치에 따라 3개 지역으로 구분하였다. 조사 결과 남양호 수초 군락에서 번식하는 물새들은 낚시꾼 수가 적고, 낚시꾼으로부터 멀리 떨어진 곳을 선호하는 것으로 밝혀졌다. 또한 둥지 밀도는 낚시꾼 수가 적은 쪽 수초 군락에서 높았다. 따라서 주요 번식지에 대해 물새들의 번식 밀도를 높이고 안정적인 번식을 유도하기 위해서는 번식기 동안 낚시를 포함한 수상 레저 활동을 금지 또는 제한해야 하며, 이에 대한 분석과 체계적인 관리가 필요하다.

  • Coastal economic activities usually generate externalities to other economic activities. The conflicts between coastal economic activities, especially land fillings and reclamations, and fisheries in coastal waters pose a typical one, which sometimes causes some social conflicts. In this regard, as the contents and requirements for rules and regulations on fisheries compensation may have important implications for solving such problems, important is to review rationales fur the formulas in calculating fisheries compensation. The purpose of this paper is to review the formulas for fisheries compensation from the economic view points, to highlight some problems and to suggest more appropriate formulas. It is found that the current formulas of fisheries compensation are not properly based on economic concepts and valuation techniques. Main problems are related, as followings, to the coefficient(0.8) employed in the formula, to fishermen's own wages and to current values of invested assets such as fishing boats and nets, etc.. First, it is not clear what the coefficient(0, 8) means. In Japan's case, the coefficient was assumed to reflect the opportunity cost of fishermen's own wages, but it was disappeared from the formula after the self-wage came to be included in totaling fishing cost. As our new formula will include the self-wage in fishing cost, the coefficient(0.8) should be excluded. Second, according to our formula, the current value of invested assets is added to total operating compensation, which will overestimate total compensation. Therefore, it is suggested that total present value of the assets to be invested during the business life should be deducted from total operating compensation. Third, as the self-wage will be included in total cost, opportunity cost for finding new jobs should be newly added to the formula. Finally, this paper also conducted a comparative case study considering above-mentioned factors. The case study showed that the current formulas overestimated total fisheries compensation.

  • We compared the structure of fish community and condition of major fish species in Lake Chungpyung and Lake Paldang, which are relatively shallow, meso-eutrophic, cascading dam reservoirs on the North Han River. Two lakes have wide littoral zone in the lakeside providing similarly good habitat for fishes, whereas fishery and water recreational activities such as motorboating, water skiing are allowed in Lake Chungpyung but are prohibited in Lake Paldang. The average lengths of large size fishes in Lake Chungpyung are shorter than those of same species in Lake Paldang, resulting in the slight distortion of generation distribution of those species in Lake Chungpyung, possibly owing to the active fishery such as fixed shore net fishing, gill net fishing and angling. Meanwhile the condition of fishes represented by the length-weight relationship of fish species did not show the significant differences between two lakes and showed normal condition. To evaluate the impact of physical disturbance such as loud noise and turbulent wave from water recreational activities to fishes precisely, further studies including physiological responses to stress an spawing activity should be needed.

  • For providing a basic data concerning with a fishing deck layout design of a trawler the authors conducted the video observations about the working activities of crews on the deck in the different layout of two Korean coastal large stern trawlers (gross tonnage: 139). The winch of the trawler-A was installed on the aft of the fishing deck and the trawler-B, on the forward of the fishing deck. The work and activities of the deck hands on both trawlers were observed using the CCD (charge coupled device) camera installed on each trawler's deck for one month from August 3, 2010. The video data was analyzed by the hierarchical task analysis (HTA) method. In results, numbers of tasks to require deck hands during the hauling net and the casting net were 25 and 28 for the trawler-A and 27 and 48 for the trawler-B, respectively. The working processes were represented a same in both of the trawlers. Location for controlling the deck machineries, the location installed trawl winch, kinds of deck machineries, crew's custom for using deck machineries were the factor affecting to the number of the task. In the case of the improvement suggested in the results is carried out, the reduction percentages of the number of task in the trawler-A and trawler-B were estimated as 24.5% and 51.3%, respectively. Through this study it was found that the quantitative analysis is possible for the work processes, work methods and the work contents in the trawler. Also the suggestion for improving the fishing deck layout design of the trawler was possible by finding out the factors increasing the number of tasks and removing the tasks. We expect that the results of this paper are used as a basic data for designing the layout of deck machineries in the trawler in the future.

  • 소형어선 검사제도와 관련하여 최근에 정부에서는 선박검사대상에 제외되었던 선외기등 총톤수 2톤 미만의 선박(이하 소형어선)에 대하여 선박안전법 적용대상으로 확대하여 어민들의 안정적인 조업활동을 지원하여야 한다는 근거하에 선박안전법 개정(제3조)에 관한 입법이 추진중에 있다. 소형어선의 검사여부 문제에 대해 어선의 안전확보 차원에서 검사를 해야 된다는 측면과 영세민과 노년층으로 현행 검사비 및 검사수수료의 비용 부담 및 어선검사를 받는데 소요되는 많은 시간 등의 문제로 종전과 같이 검사대상에서 제외되어야 한다고 주장하고 있다. 이러한 상반된 의견에 대한 대안으로 영세어민의 생업에 사용하거나 소형어선에 대한 검사는 원칙적으로 선박의 소유 또는 사용자가 자발적으로 수행하여야 하며 행정적인 규제는 이러한 목적 달성을 위한 최소한의 정책수단으로 제한되는 것이 바람직한 것으로 나타났다. 또한, 주요 수산국들 처럼 우리나라도 소형어선 검사를 위한 다양한 프로그램개발이 필요하다. 특히, 소형어선에 대한 검사를 실시하는 경우, 어선검사료 정부 지원, 최소한의 안전확보 검사, 어선건조시 검사, 검사기간을 연장하는 방안을 고려하여 정책을 추진할 필요가 있는 것으로 파악되었다.

  • 본 연구에서는 동태성과 시간을 고려한 시스템다이내믹스 관점에서 낚시어선의 낚시활동에 있어서 단속 및 처벌의 강화(정책개입)에 따라 시스템 구조가 어떻게 변화하는지 알아보고 그에 따른 전략수립 방향을 논의하고자 한다. 지금까지 낚시어선의 단속과 처벌은 사고예방이라는 사전적 차원에서 일시적 단기적으로 단속을 실시하고 처벌을 부과했다. 그러나 변칙적이고 다양한 부작용으로 소기의 성과를 거두지 못하였고, 안전사고는 끊임없이 발생하고 또 다시 후속조치가 뒤따라가는 형국을 보이고 있다. 본 연구의 결과에 따르면, 낚시어선의 단속과 처벌이 강화된 안전기준으로 사고 예방을 위한 시설 장비 산업 등 관련 사항 개선 및 기술개발(시간지연 발생)보다는 즉각적이고 큰 저항이 없는 음성적(불법적) 활동을 지속함에 따라 사고예방을 위한 안전사각지대를 최소화하지 못하고 있다. 이와같이 동태적 매커니즘과 시간이라는 변수를 충분히 고려하지 않고 단선적 사고에 입각한 정책개입으로는 정책이 추구하는 기본적 가치를 오히려 왜곡시킬 수 있다. 낚시어선의 단속과 처벌에 있어서 강화된 안전기준의 마련에 앞서 관련 기술의 개선 및 개발, 낚시인·낚시산업체·관련기관 등 다양한 주체들에 대한 교육시간 의무화, 낚시관련 산업 육성을 위한 낚시 관리 및 육성법의 구체적인 방안 제시와 같은 매커니즘을 보완하는 전략을 마련해야 한다.

  • The purpose of this study is to elucidate the impact of authenticity on experience value and subjective well-being among visitors who have participated in direct experiential activities in experiential fishing villages. The research method used literature research methods and empirical research methods using questionnaires, and this questionnaire was composed by determining three major variables and seven constituent factors for each variable through factor analysis and conducting prior research and preliminary surveys. The survey was conducted from February 5, 2023 to April 5, 2023 among experimental fishing villages with excellent ratings for scenery (environment), service, experience, accommodation, and food, and four villages that can experience tidal flats and manage customers online. The survey was conducted from February 5, 2023 to April 5, 2023, among experimental fishing villages with excellent ratings for scenery (environment), service, experience, accommodation, and food, and four villages that can experience tidal flats and manage customers online. The results of this study are as follows. First, the factors of authenticity in experiential fishing villages include three sub-factors: objective authenticity, constructive authenticity, and existential authenticity. The factors of experience value include two sub-factors: emotional values and functional values. Subjective well-being is derived from positive emotion and life satisfaction. Second, upon examining the importance of authenticity in experiential fishing villages, it was found that existential authenticity and objective authenticity, in that order, have a significant impact on emotional values. However, constructive authenticity did not have a significant impact on emotional values. Third, in terms of functional values, constructive authenticity, existential authenticity, and objective authenticity, in that order, had a significant impact. Fourth, experience value, in the order of emotional values and functional values, had a significant impact on positive emotion and life satisfaction of subjective well-being. Therefore, it was confirmed that the authenticity of experiential fishing villages is important as a strategy to enhance experience value and subjective well-being. Especially, considering that the majority of visitors to experiential fishing villages are family-centered (86.5%), applying marketing management strategies to develop programs that enhance existential authenticity and improve emotional values could elevate the subjective well-being of experiential visitors.

  • The purpose of this study is to obtain a basic data on layout of the trawlers' bridge equipment. The task activities of bridge workers involved in the navigation and fishing operation were analyzed by link analysis methods. The results are as follows. It was found that the movement pattern and frequency of bridge workers are different accordance with the bridge work (navigation, casting net, towing net and hauling net). The central workstation of movement of the bridge workers was a radar workstation, a steering workstation and a trawl winch workstation in the bridge work. But the radar did not show up as the center of movement during the hauling net. Workstations related deeply to the central workstations of the movement on the bridge were as below. Radar workstation was related to a GPS plotter, a microphone location for external communication with VHF and MF/HF equipment and a steering in the case of the navigation, the steering, the GPS plotter and the net monitor in the case of the fishing operation. Steering workstation was related deeply to the GPS plotter, the radar in the case of the navigation, a speed controller, the GPS plotter, a fish finder, the net monitor and the microphone location in the case of the fishing operation. Trawl winch workstation showed deep relation with the GPS plotter and the speed control during the fishing operation. Through this study, it was found that Workstations related deeply to the central workstation of the movement of the bridge workers in accordance with the bridge work. The results of this study might be utilized as the basic data on the bridge layout to minimize the fatigue degree due to a physical movement of the bridge workers.

  • A quantitative method was suggested for estimating damages in fishery production due to the diffusion and deposition of suspended silt and clay by various construction processes in tidal flat fishing grounds. Marine populations are maintained through the process of spawning, growth, recruitment, natural death and death by fishing each year. All of the year classes of the population in a fishery ground could be affected when damages occur by human activities such as land filling or reclamation. The propose of this study is to calculate damages in terms of fishery production using a quantitative population dynamic method. If the maximum age in the population is $X_\lambda,$ the starting year of damage is $t_s,$ and the ending year of damage is $t_e,$ the number of year classes damaged is $t_{s-n\lambda}-t_e,$ Many year classes present in the year $t_s,$ and so if damages occur, they Influence all the year classes which are present in the population. Damaged year classes in year $t_e$ would still be in the population until the year $t_{e+n\lambda}$, where $n_{\lambda}$ is the oldest age class. If the expected yield of a year class is constant, the total yield from year classes in the fishing ground during the construction periods can be calculated as follows: $Y_\Phi=[(t_e-t_s+1)+n_c]{\cdot}Y_E+\sum\limits^{n_\lambda-n_c}_{l=1}\;\sum\limits^{n_\lambda-n_c}_{l=i}\;Y_{n_c+i}$ This method was applied for damage estimation in the production of Ruditapes philippinarum in a tidal flat fishing ground.
