The problem started in 2005 when Nomura’s Jellyfish “an enormous Jellyfish that can grow up to 6.5feet in width and can weigh up to 220KG” inundated Japanese waters. The jellyfish use to be the common creatures of Korea and China, but back in 2005-2006 Nomura’s jellyfish numbers increased in some specific areas of Japanese waters, which caused a crisis in local fishing industry. According to reports the Nomura’s Jellyfish choking fishing nets and poisoning the catch with their venomous stingers. However, the fatal injuries to humans are rare but the people did die and are still dying from the Nomura Jellyfish lethal stings.
All these events related to Nomura Jellyfish prompted the Japanese government to start a series of research and studies about the mating and migration habits of the creature, which were poorly understood in the past.
According to a study in 2006 Japanese scientist considered that heavy raining in China’s Yangtze Rivers Delta is the reason that Nomura Jellyfish are drifting towards the Japanese waters. Another study shows that due to global warming and sea water heating are suitable for Nomura Jellyfish to bread that is why they are moving towards warmer waters as a flotilla. But eventually the problem increased when the scientist find out that when the jellyfish are under attack or killed they discharge billions of eggs and those eggs attach themselves to rocks and coral structures, and when the conditions are in favor those eggs detach and grow into jellyfish millions at a time.
So Japanese coastal communities as a solution tried to promote jellyfish as a unique food; this problem led Japanese government to form a committee to fight with this problem before they can do any more harm but until yet without any results.
