Historical trends of trophic diversity, fish body size, red tides (harmful algae blooms) in coastal ecosystems, and fish production in China. Aquaculture and catch data of marine fish, freshwater fish, and diadromous fish (A) were developed by the Food and agriculture organization of the United Nations (http://www.fao.org/fishery). The change in fish trophic level indices (the trophic level of primary producers set as 1) and mean body length data (B) were developed by the Sea Around Us Project (http://www.seaaroundus.org). Annual occurrence and area of major coastal algae blooms (red tides) data (C) were extracted from the Marine Bulletins of the State Oceanic Administration of China (http://www.soa.gov.cn/zwgk/hygb) and references [20].
