Scientists have cast question on the widely retained perception that there has ever been global increase in jellyfish.
Blooms, and or proliferations, of jellyfish may reveal a significant, visible effect on coastal populations– congested nets for fishermen, burning waters for tourists, possibly even choked air conditioning intake pipes for energy power plants– and current media reports have made a perception that the world’s deep seas are encountering trending increases in jellyfish.
At present, a latest multinational collaborative research, including the University of Southampton, implies these fluctuations may be over-emphasized, learning that there is absolutely no strong proof for the global increase in jellyfish in the last two centuries.
The vital finding of the research proves global jellyfish populations undergo simultaneous changes with consecutive decadal durations of rise and fall, such as a growing stage in the 1990’s and early on 2000’s which has contributed to the present perception of the global increase in jellyfish sufficiency.
The early period of excessive jellyfish statistics throughout the 1970s went undetected because of limited study on jellyfish during the time, less consciousness of global-scale issues as well as a reduce efficiency for information sharing.
