This paper summarizes the changing states of the food resources in the Yellow Sea Large Marine Ecosystem under multiple stressors from 1958 to 2015, including the changing states of biomass yields, species composition, trophic level and biodiversity. The results show that the changing trends were contrary to expectation. There were no significant declines in biomass yields, trophic level and biodiversity after the 1980s. The major decline observed occurred before the 1980s. However, the species composition changed a lot, that is, over the past half century there were two different types of species shift in YSLME under multiple stresses. One was from demersal, high value species to pelagic, lower value species shift during 1958–59 to 1998–2000, and the other was from pelagic, lower value species to demersal, low value species shift during 1998–2000–2014-15. For future sustainable development, it is still necessary to further strengthen adaptive management.
