Fishery is one of the important emission source of greenhouse gases in agriculture.We should take effective measures to control the emissions of greenhouse gases from fishery.This article is based on < China Statistical Yearbook > 、the communiqué of the Stat.about national economy and social development 、the data from < China Fishery Statistical Yearbook > and the research result of fishing boats’power consumption and energy-saving technology during 2008 to 2009 by Fishery Machinery and Instrument Research Institute,Chinese Academy of Fishery Sciences.Taking the method of calculation of the emissions of carbon by ORNL,we calculate the emissions of carbon of the fishing boats in China.The result shows: The emissions of carbon are 6.732 million tons,converting to the emissions of carbon dioxide that is 24.706 million tons.The emission of carbon that is from each units production value is 2.06 kg per Yuan,which is 3.4 times more than the average of agriculture、forestry、stock raising、fishery、water conservancy.Ocean fishing industry is the most primary area of fishing boats’power consumption and carbon dioxide’s emissions.Ocean trawling and gillnetter is the most primary source of the emissions of carbon dioxide in Ocean fishing industry.We have analyzed the most important factor of high power consumption and the emissions of carbon dioxide,providing the scientific foundation to working out measures for energy saving and pollutant reduction.
