The interest in greenhouse gases (GHG) emitted from all industries is emerging as a very important issue worldwide. This is affecting not only the global warming, but also the environmentally friendly competitiveness of the industry. The fisheries sector is increasingly interested in greenhouse gas emissions also due to the Paris Climate Agreement in 2015. Korean industry and government are also making a number of effort to reduce greenhouse gas emissions so far, but the effort to reduce GHG in the fishery sector is insufficient compared to other fields. Especially, the investigation on the GHG emissions from Korean fisheries did not carry out extensively. The studies on GHG emissions from Korean fishery are most likely dealt with the GHG emissions by fishery classification so far. However, the forthcoming research related to GHG emissions from fisheries is needed to evaluate the GHG emission level by species to prepare the adoption of Environmental labels and declarations (ISO 14020). The purpose of this research is to investigate which degree of GHG emitted to produce the species (swimming crab and snow crab) from various fisheries. Here, we calculated the GHG emission to produce the species from the fisheries using the life cycle assessment (LCA) method. The system boundary and input parameters for each process level are defined for LCA analysis. The fuel use coefficients of the fisheries for the species are also calculated according to the fuel type. The GHG emissions from sea activities by the fisheries will be dealt with. Furthermore, the GHG emissions for producing the unit weight species and annual production are calculated by fishery classification. The results will be helpful to establish the carbon footprint of seafood in Korea.

This study intends to review the development of Squid Angling Fisheries of Korea and Japan and subsequent changes in the fisheries regime as well as management conditions and to examine reorganization directions. Although catches and productivity are all increasing in Korea and Japan as the squid resource in the East Sea is improving, the number of fishing vessels and the conditions of fisheries management are showing a symmetrical relationship. The former is increasing in Korea and decreasing in Japan while the latter is aggravating in Korea and rather stable in Japan. And while the competition between the two countries for more fishing grounds and catches are not that serious since the resource is relatively increasing, the catch and price competition with other domestic fisheries is a more significant problem. Furthermore, even though light restriction is implemented in both countries in order to suppress over-competition, it is adopted as a means to curtail management costs and block over-investment rather than to adjust international or inter-fisheries circumstances. Japan has been implementing the TAC system on squid resources since 1998. However, it has a different meaning than as a resource management method in its original sense because it is based on the highest catch level of the past and takes into consideration the fishermen's management conditions. In case of Korea, it is necessary to establish a plan to strengthen its fisheries management competence to address its shrinking catch in the Japanese waters. The developments mentioned so far have appeared amidst the increase of squid resources, and if such conditions disappear, problems such as international allocation of catches and fishing seasons, access to fishing grounds, and domestic conflicts among different fisheries will emerge.

To understand the fishery characteristics by a beam trawl off the coast of the Chungnam province, covering $125^{\circ}$ 50'~$126^{\circ}$ 05'E, $36^{\circ}$ 15'~$36^{\circ}$ 25'N, a beam trawl was deployed 2~4 times a month from March 2008 to February 2009. The catch was consisted of 96 species of 63 families belonging to 19 orders. Among these, organisms were identified as 54 species of fish, 27 species of crustaceans, 9 species of gastropoda, bivalves, and 6 species of cephalopods. Trachysalambria curvirostris which is the target species of the beam trawl fishery occupied only 2.1% of the total catch, showing a low ratio of catches. Most of T. curvirostris was harvested from July to November while small amount of T. curvirostris was captured from May to December. In this study, we concluded that the bycatch ratio except T. curvirostris in T. curvirostris fishery was relatively high, thus the fishery of T. curvirostris might affect the fishery resource management of bycaught species off the coast of Chungnam province.

Marine spatial planning(MSP) designates the marine as nine kinds of use zones for the systematic and rational management of marine spaces. One of them is the fishery protection zone, which is necessary for the sustainable production of fishery products, including the protection and fosterage of fishing activities. This study intends to quantitatively identify the fishing activity space, one of the elements necessary for the designation of fisheries protection zones, by mapping of fishery activities using V-Pass data and deriving the fishery activity concentrated zone. To this end, pre-processing of V-Pass data was performed, such as constructing a dataset that combines static and dynamic information, calculating the speed of fishing vessels, extracting fishing activity points, and removing data in non-fishing activity zone. Finally, using the selected V-Pass point data, a fishery activity map was made by kernel density estimation, and the concentrated space of fishery activity was analyzed. In addition, it was confirmed that there is a difference in the spatial distribution of fishing activities according to the type of fishing vessel and the season. The pre-processing technique of large volume V-Pass data and the mapping method of fishing activities performed through this study are expected to contribute to the study of spatial characteristics evaluation of fishing activities in the future.

It takes lots of time and labor if a worker have to measure the water quality at a certain but designated time every day in an un-automated aqua farm. In addition, if the equipment is soaked in the sea water consistently, it will be contaminated by diverse floating matters and barnacles, and it often becomes mal-functional within 2~3 months. Therefore, we need to develop a system with which the sensed data could be checked in real time and operated automatically, while preventing the contamination of the sensor, a crucial component for water quality measuring equipment, as much as possible, and increasing the replacement cycle. We have developed a non-cleaning water quality measuring equipment and its software which are used in the fishery household of offshore aqua farms. By providing the workers with a mobile application which has a function of monitoring the water quality in real time, they can check the situation directly without going to the fishery household.

For establishment of post-Unification fisheries program, this research has opened a fisheries Act system for South and North Korea and searched a policy direction to make new Fisheries Act for future South and North Korean fisheries program. In addition, North Korea's present fishery industry must be accurately understood and acknowledge in its point of issues in order to develop and improve to rational direction and to overcome the present South and North's fishery industry. As a level to prepare for future unification, reform and reaction of long-termed and well organized South and North's fisheries program must be arranged. Consequently, fishing permits of South and North, licensing system, fisheries resource management system, fisheries adjustment system, foreign fishing regulations system will be compared in this research, and also find an improvement on North Korea's fisheries related act in preparation of future unification.

Fisheries finance is divided into the policy time of long period of time and low interest and the special financing institutions, such as Fisheries Co-operatives. Union system finance is the system finance, which supports the fisheries system organization. Fisheries Co-operatives in cities, towns and villages are the independent management objects. Prefecture federation of Fisheries Co-operative is in prefecture stage. Norm Chukin Bank is in national stage. Each shares functions in these three stages, and finance is performed systematically, Fisheries policy finance comprises government financial institution capital such as the Agriculture, Forestry and Fishery Finance Corporation whish is based on the capital of a country or a prefecture financial fund, and fishery Modernization Capital used as financial funds through the government. Moreover, to complement such finance institutionally, Fisheries Credit Foundations, Agriculture and Fisheries Saving Insurance Corporation and National fisheries Co-operative Trust Enterprise Mutual Aid system have been established

Main target of fishing policy was enlargement of fishing catches in Korea after 1960s. This has caused sustainable decrease of the amount on the fisheries resource. In the result, fishing managements in Korea have suffered from aggravation of management. In this research, it is estimated the technical efficiency on Korean Off-shore Stow Nets Fishery that was made publication by Farrel in 1957. According to the analysis, Its were excessive to the gap of technical efficiency among Korean Off-shore Stow Nets Fishing boats. The gaps were excessive not only among each fishing managements but also by tonnage class and by region. Then we can recognize we need the change of Fishing Policy. That is, we should change for main target of fishing policy from enlargement of fishing catches to the policy of Price. And we should consider the supply of standard tonnage boats and specialization of fisheries by regions.
