Abstract：In the past years, with the increasing market demand and the yield of sea cucumber processing production, the environmental problems for sea cucumber processing industry as an important fishery production processing industry in Northern China have become increasingly prominent. A cleaner production indicator system for sea cucumber processing industry is established including 6 first-grade indicators and 24 second-grade indicators based on the Chinese cleaner production technical system and the characteristics of sea cucumber processing process and practiced in several enterprises to promote the cleaner production and to ensure sustainable development of sea cucumber processing industry in China. It is found that the cleaner production level of the tested enterprises is Ⅱ level, that is, domestic advanced level of cleaner production. The evaluation results and operation status of the case enterprises proved that the indicator system is well scientific, operable and applicable. According to the evaluation results, the cleaner production improvement measures were proposed for the case enterprises including change in the energy type and improvement of the utilization rate of waste resources, which also provided beneficial reference for the cleaner production of fishery production processing industry in China.
