Impact assessment of non-indigenous jellyfish species on the estuarine community dynamic: A model of medusa phase by Muha, Teja Petra

“…Low water discharge and low nutrient retention rate appear to be the most favourable conditions for B. virginica. The species is a non-selective predator able to integrate into the system effectively and has caused a decrease in the biomass of other organisms in the estuarine ecosystem throughout the summer after dam removal. …”
