The frequent, massive summer mortalities of sea cucumbers have caused considerable economic losses and resulted in a serious decline in resources, which in turn has restricted the sustainable development of the industry of sea cucumber. This study analyzed the causes of the massive summer mortality of sea cucumbers considering environmental factors (including high temperature, low dissolved oxygen, low salinity, sulfide, ammonia nitrogen, and decayed algae), germplasm, pathogen, and anthropic factors. Based on that the analysis results, we proposed the concepts of "construction engineering", "farming mechanization", "monitoring automation" and "intelligent management". In addition, for ensuring the health of sea cucumber in summer, a series of corresponding strategies have to be implemented:for example, stress-resistant seed cultivation, sediment and water quality investigation, development of a comprehensive breeding system and risk pre-warning system, and improvement of an emergency plan and modern breeding technology.
