From the economic point of view the fishing port is the complex of installations on land, organized to serve the fishing fleet and its cargo, and is the main link in the production chain of all components of the fishing industry, with the aim of achieving the planned targets with the minimum cost. Fishing port investment decisions have had significant impact on the development aims of Korean fisheries. Fishing port investments in Korea are made mostly by public or semipublic port authorities. Such investments should be judged not purely on the basis of financial profitability but rather on the extent to which they serve the development aims of the fishing industry. This makes the economic appraisal process more complex and presents certain problems in correctly quantifying the economic costs and benefits of the fishing port projects. This study concentrates more on the theoretical economic appraisal models than on the purely financial aspects of fishing port investments and points out the difference between the two approaches. In the result, there is clearly an element of judgment as to whether or not a shadow price needs to be used in estimating economic benefits and costs. From this viewpoint, some attempts are made to provide definitions of the possible economic benefits and costs, and methods for estimating and evaluating them in Part III and IV. Especially queueing theory is applied in the calculation of economic benefits. When a project is contemplated and analysis shows it to Lave a positive NPV, one question that arises is whether it should be implemented now or delayed. In this paper, the first year rate of return method is regarded as a more concise way of solving the timing of investment, At the end of Part IV, risk analysis of fishing port investments is considered. It can be handled in a number of ways, ranging from informal judgment to complex statistical analyses involving large-scale computer models, This paper recommends that evaluators of fishing port investments use the sensitivity analysis indicating exactly how much NPV will change in response to a given change in an input variable, other things held constant. Decisions regarding the amount of capacity to provide must be made in fishing port investments. Providing too much service would involve excessive capital costs. On the other hand, not providing enough service capacity would cause the waiting line of fishing vessels to become excessively long at times. Therefore, in Part V, the optimal number of berths and berth productivity in fishing port are defined as follows: Minimize E(TC) ＝ E(WC)＋E(SC) The minimum of this function is the solution and that is the optimal number of berth and berth productivity in fishing port.

The fishing conditions of flying squid, ommastrePhes barsram(Lesueur), in the North Pacific Ocean was studied based on the horizontal water temperature data, satellite data from NOAA and statistical data of flying squid fisheries which were collected from 1980 to 1984. The obtained results were as follows; 1. Since 1979, the Korean drift giIlnet fishery for flying squid was launched in North Pacific. Number of operating vessel and catch of flying squid increased gradually every year. The number of vessels were 111 and their annual catches were 42, 977 M/T in 1984. Therefore, Korean drift giIlnet fishery for this species has played an important role in the products of Korean high-sea fisheries. 2. In the beginning of the fisheries, fishing grounds was formed in the west of long. 1800E. In 1982, in consequence of the center which extended eastward, the fishing ground was formed long. 166$^{\circ}$W in the central North Pacific Ocean. Since 1983, the fishing grounds were formed as far as long. 161$^{\circ}$W. The range of general fishing season in the central North Pacific was from June to August. After september, fishing ground was shifted to the west, in the Northwestern Pacific. 3. The Predominant fishing season for the flying squid was August through January of the coming year. Optimum water temperature for flying sguid at surface layer in the Pacific Ocean ranged from 11 $^{\circ}$e to 17$^{\circ}$e in winter, 13$^{\circ}$e to 17$^{\circ}$e in spring, 12. 8$^{\circ}$C to 19.7$^{\circ}$e in summer and 1O.6$^{\circ}$e -18.7$^{\circ}$e in fall. 4. In summer, the Oceanographic condition in the North Pacific Ocean showed that the water temperature at surface layer was lower in 1980, 1983 and higher in 1981, 1982 and 1984 as compared with mean annual water temperature. 5. The characteristics df oceanographic conditions in the fluation, disformation, mixing and other factors of the Kuroshio and Oyashio currents, which have considerably influenced upon the water masses of the areas. 6. The data and information on surface thermal Structure interpreted from Infrared Satellite Imaginary from NOAA-7 and NOAA-8 are very available in estimating water temperature on the areas and investigating the major fishing grounds. 7. According to the fisheries statics of Japanese drift gilInet, the annual catches of flying squid considerably decreased from 225, 942 M/T in 1983 to 133, 217 M/T in 1984. 8. The fishing grounds in the central North Pacific in several fishing seasons were formed as follows: In June, the initial fishing season, the fishing grounds were formed in the vicinity of lat. 35 - 40oN, the central North Pacific east of 179$^{\circ}$E. In July, the fishing ground were formed in the wide arEa of the central North Pacific north of 400N and long. 174$^{\circ}$E-145$^{\circ}$W In Auguest, concentrative fishing operation carried out in :he central North Pacific north of 43$^{\circ}$N and East of 165$^{\circ}$W. On the other hand, in September, main fishing grounds were disappeared and moved to the west.

The fishing lamp is a fishing gear that gathers fish at night. But the cost of oil, which is used to light fishing lamp, has been risen significantly up to 30-40% of total fishing costs. Therefore it is very urgent to develop an energy economical fishing lamp in order to solve the business difficulties of fisheries. Under this background, this research aims at developing a fishing lamp for squid jigging and hairtail angling fishery using the LED, which has excellent energy efficiency and durability. The LED fishing lamp developed can be controlled to fix a fit direction of fish shoal deep because a fishing lamp can be adjustable up and down directions. One unit of fishing lamp has about an 80Watt capacity and the frame of fishing lamp is made of aluminium to emit generated heat of LED to outside. The LED lamp developed was highly durable, only 5.7% of emitting efficiency decreased for 18 months. The illuminance of a unit LED lamp was 2,070lux at 1m and 21lux at 10 m distance, and the intensity of LED lamp system emitted 2,580lux and 400lux at the respective distances. After development of this fishing lamp, 100 units are installed on operating fishing vessels. Experimental results show that energy consumption of squid jigging and hairtail angling was reduced by 40% and 87%, respectively. In conclusion, our methods showed elevated fishing power, compared with traditional fishing method: 37.7% for squid jigging and 24.5% for hairtail angling.

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.

Nowadays managers of fisheries enterprises and users of accounting information have a considerable interest in the fishery right. The fishery right, which is given by administrative quarters, is referred to exclusive fishing right in a certain coastal fishing ground, and it has been one of the property rights since the turn of the century. The main purpose of this study is to provide an improved accounting method of the fishery right from the side of accounting. To achieve this purpose, legal nature of the fishery right should be understood in the first place, for the fishery right, an intangible asset, is a sort of property right guaranteed by the fisheries laws, According to the basic law in the fisheries "Fisheries Law, " the fishery right is broken down largely into three categories; culture fishing right, set fishing right and common fishing right. The legal characteristics of these fishery rights are as followings: 1. The fishery right is a private right. 2. The fishery right is a property right. 3. The fishery right is a right in rem, and legal provisions pertaining to land are applied to the fishery right with necessary modifications. In addition to the above fishery rights, the Fisheries Law provides some provisions on the so-called entrance right, and those who obtained the right are authorized to access to a certain common fishing right fishing ground where they have been traditionally fishing. In the inland fisheries, the fishery right system similar to that of the coastal fisheries discussed above is adopted in conformity with the Inland Fisheries Developing and Expediting Law. Viewing from an angle of accounting, there are two kinds of additional fishing rights which are dealt as assets. These fishery rights dealt as asset include the license of entry in the so-called permitted fishing which is also called as fishery right in plain language, and tile entrance right obtained abroad. Although these two kinds of rights are not the fishery right from a viewpoint of law, they are regarded as fishing rights in accounting which intends to provide a useful economic information.formation.

우리나라 남해안에서 플라스틱 붕장어 통발을 사용하는 통발어선이 연간 유실하는 통발의 개수는 통상 조업시 시용하는 통발의 2~4배인 것으로 나 타났다. 이러한 통발의 유실은 보통 조업중에 발생되므로 어구의 유실과 함께 어획물의 손실도 발생하게 된다. 어획불과 미끼가 들어있는 유실된 통발 은 붕장어뿐만 아니라 다른 해양 생물을 유인하여 어획할 수 있는 것으로 밝혀졌다. 그리고 유실된 붕장어 통발에는 어류, 갑각류, 두족류 등이 들어있었고, 이들 가운데는 붕장어의 먹이가 되는 베도라치, 청보리멸, 양태, 붉은메기와 새우류 등이 어획되어 있었다. 따라서 조업시 어획된 붕장어 이외에도 붕장어가 이들 통발 속에 들어있는 어획물을 섭이하기 위해 통발에 들어가므로서 추가적인 Ghost fishing의 가능성은 크다고 할 수 있다.

Fishing village is becoming the central base of fishing industry and it plays a major role. However, there is a decrement of marine resources and some difficulties with the deterioration of fishing industry management. In order to solve these problems, there should be some developments(e.g. fishing village toursim development) on various undergoing government and the private organization programs. Nevertheless, there are not guidelines for fishing village tourism development to utilize for practical business. Therefore, it is necessary to understand the current status and guidelines regarding the development of fishing village for coastal planner. The primary purpose of this study is to investigate the characteristics of fishing village development works in Korea and Japan. The second purpose is to identifie success factors after analyzing individual success cases. Based on evidence from the literature and a dialogue with village leader, a literature review on extracting success cases for guidelines were selected according to criteria such as the degree of contribution to an increase in income of the fishing village, the degree of contribution to an increase in consumption of marine products using local natural resources, the number of tourists that visits the village. Finally we propose guidelines for future fishing village development projects. The guidelines based on the successful cases, as well as the major factors about the objectives and direction of fishing village tourism development, suggested as follows. 1)Plans for land use, 2)Development of tourist resources, 3)Plans for views, 4)Plans for resource protection, 5)Plans for operation and marketing.

This paper was concentrated on the distribution and the composition of lost fishing gear on the sea bed around yellow croaker fishing ground in the near sea of Jeju, Korea from April to October 2009 in order to improve the fishery environment. Recovering lost fishing gears was carried out total 10 times with a trawlnet along the isobath. As the result, it seems reasonable to conclude that the amount of lost fishing gear has a deep connection with the dip of the sea bed as well as the fishing gear scale, fishing ground and so on. The amount of recovered lost fishing gears were in order of gillnets, dragged gears, traps and ropes. In particular, traps were recovered almost every time within the survey area.

The set-net fishing is involved in the trap fishing method that intercepts the fishes migrating along the coast and induces them to be in the bag net stretched in advance. And this fishing also corresponds to the licensed fishing in fisheries law. Though its annual total production of around 50,000 to 70,000 M/T is less than in other fishery section, its price becomes higher because the fishes are sold in the live fish condition. Until recently, the set-net fishing is one of the preferred fisheries on account of its less operation expense and stably operating condition in a long term. In the meantime, the industrialization in Korea having been prospered along coastal area and the over fishing in terms of the powered and larger size fishing boat make the fishing ground environment worse yearly. In addition, its difficulty becomes more worse with issuing fishery product free import in July 1997; accordingly, the strategy for the set-net fishing through business rationalization should be considered. From the discussion of the sort of set-net, general present situation and operating actual state of set-net fishing, the improved methods for business rationalization in the present paper is proposed as follows: 1. to increase the fisheries resource through prevention of the marine contamination and purification of coastal area environment. 2. to save the labour cost through the improved the fishing gear. 3. to improve the fish quality through development of the process technology. 4. to increase the income of fishers through improvement of the distribution channels.
