Jellyfish blooms challenge the provisioning of ecosystem services in the Korean coastal waters

Abstract Temperate fisheries grounds are exposed to compound effects of jellyfish proliferations and fishing pressure, which affect local fisheries, cause economic losses, threaten seafood supply. Here, we quantify the interlink between climate variability blooms their impact on Japanese anchovy ( Engraulis japonicus ), in Korean coastal waters. We used a bioclimate dataset (2010–2019) that includes quantitative information two major bloom-former species, Aurelia coerulea Nemopilema nomurai , Peninsula. show phenomena governing East Asia regions explain circa half variability. In turn, have significant negative effect interannual changes r = -0.47, P < 0.01), varies along with bloom magnitude. Our results indicate intensity blooms, more than duration, has predominant production. also suggest possibility using signals for assessing eventually predicting, abundance These stress challenge posed by provisioning ecosystem services via influence marine harvested fish further highlight need integration into ecosystem-based management.
