In recent years, massive blooms of jellyfish and jellyfish-like creatures have overrun most of the ocean in the world. When distributed in reasonable numbers, native jellyfish play important ecological roles.  But when jellyfish populations run wild,they may damage the populations of these commercial fish, cascade up the food chain,help cause massive algae blooms,significantly change the pelagic foodweb structure with their pulsating, gelatinous bodies. 

Little is know about the fate of jellyfish biomass after their population crash.Jellyfish release nutrients and dissolved organic matter through their activities.The ecological impact of jellyfish proliferations on foodweb structure and dynamics may at times be significant. Especially in the trophic control,from the upper trophic level to the lowers,and the fate of the carbon and nitrogen bound in the jellyfish population after their crashes. In addition, Bacteria have an important role in the circulation of nutrients in the marine ecosystem. We therefore expect that bacteria also play an inportant role after the population of jellyfish crashed. How does the bacteria affect in the degradation of mass jelllyfish? So we want to know everything about bacteria who associated with jellyfish.
