摘要: Blooms and strandings of Chrysaora plocamia are reported to occur along both Atlantic Pacific South American coasts. First described in Peruvian waters by Lesson (1830) almost two centuries ago as Cyanea plocamia, there is surprisingly little ecological information about this conspicuous animal. This chapter reviews current knowledge C. biology ecology, its relationship with pelagic fisheries climate the problems blooms cause Humboldt Current Patagonian shelf ecosystems. has important roles, including trophic symbiotic interactions fish sea turtles. Population variability a clear where phases high biomass were associated El Nino events occurring during warm “El Viejo” regimes. Interestingly, their estimated occasionally approached those sardines or anchovies. large jellyfish negatively affects human industries region when abundant, fisheries, aquaculture, desalination plants tourism. Understanding relationships between environmental drivers (e.g. ENSO, regime shifts) should allow forecasting abundance potential vulnerabilities such that resource managers industrial owners may prepare for costly outbreaks.
