Since the Industrial Revolution, mankind faced with the problem of global warming. Each country effort to reduce greenhouse-gases emissions constantly. In the case of Korea, they declared that they will reduce greenhouse-gases voluntarily at “intergovernmental Panel on Climate Change” held in Cancun, Mexico, in 2010. In addition, the government said that they would decrease to 30% of greenhouse-gases emissions figure in 1990 until 2020. Furthermore, they will effort to reduce greenhouse-gases emissions continuously. In Korea, fisheries research of greenhouse-gases is in the beginning stages. Therefore, the generated greenhouse-gases in fisheries should be reduced. It means that we need to quantify the emission of greenhouse-gases. In this study, we proposed a quantitative analysis method about greenhouse-gases emissions in fisheries. The greenhouse-gas emissions were derived for producing 1kg of round weight of fish and 1 ㎏ of edible weight of fish quantitatively. In addition, we derived annual greenhouse-gases emissions using the greenhouse-gases emissions for producing 1 ㎏ round weight of fish and the annual production. As a result, the present study will be based for reducing greenhouse-gases emissions.
