摘要
我国水产系统的能耗，捕捞业占居了70％，与此关系最密切的是渔船及渔船柴油机。从目前的情况来看，渔船的船型和机型都显得比较陈旧，型号繁多，能耗大，跟国外相比差距较大。因此，必须对现有渔船和主机进行选优定型，进行适当的技术改造。
Energy consumption by fishing industry in China accounts for 70 percent of total energy consumption in the fisheries of the country, mainly owing to the fuel consumption by pewer machine in fishing vessels. The models of fishing vessels and their engines are quite out of date, having a wide gap between the country and advanced countries. Consequently, technical transformation must be carried out in the field, including the optimum model selection. Systematic discussion has been made in the paper according to the reality in Fujian province.
