- 2013 Sep, Oskarshamn, Sweden. Oskarshamn Nuclear Power Plant #3. The Oskarshamn nuclear power facility produces about 10% of the electricity needs of Sweden. The Plant was shut down as tons of jellies (Aurelia aurita) clogged the cooling pipelines)
- 2013 Ireland. 20,000 farmed salmon were lost due to a jellyfish "bloom" off Clare island, Co Mayo.
- 2011 July, Orot Rabin plant in Hadera, Israel. Jellyfish blocked its seawater cooling supply to the coal-fired power plant, the jellyfish were removed at a rate of a ton an hour for five days.
- 2011 Aug, St. Lucie Nuclear Plant in Florida. Jellyfish clogged screens filtering ocean water used in the reactor cooling systems and shut down operations.
- 2011 Aug. A “massive intrusion” of Aurelia aurita into a cooling canal at the St. Lucie Nuclear Plant in Florida caused a massive fish kill, clogging the intake pipes with five tons of dead fish in the canal over a 24-hour period and triggering an unplanned shutdown.
- 2011 Jun. Torness Scotland nuclear power plant. Both reactors closed the Nuclear Plant after jellyfish found in its seawater filters.
- 2011 Jun. Shimane Japan. Jellyfish blocked seawater cooling pipes at Shimane nuclear power plant. The jellyfish managed to block the cooling system at one reactor, prompting the operator to lower its generation capacity by 6 percent.
- 2009 A Japanese fishing vessel capsized due to Normoru's Jellyfish.
- 2008 Ireland. 250,000 salmon were killed in Northern Ireland by a jellyfish bloom.
- 2008 Oct, Diablo Canyon 2 Nuclear reactor in California had to be shut down after a massive number of jellyfish clogged the circulating water screens and caused a problem with water pressure. - sea salp
- 2007 Japan. More than 15,500 reports of damage to fishing equipment caused by Normoru's Jellyfish in Japanese waters.
- 2007 Ireland. Mauve stinger jellyfish stung and asphyxiated more than 100,000 farmed salmon off the coast of Ireland, costing more than US$2m in damages.
- 2006 USS Ronald Reagan, a nuclear-powered aircraft carrier docked in Brisbane, Australia was brought to a standstill by jellyfish. More than 800kg's of jellyfish were sucked into its condensers, hindering coolant from reaching the main reactors
- 2006 The Spanish Red Cross treated 19,000 stung swimmers along the Costa Brava beaches.
- 2005 Aug, Oskarshamn, Sweden. Oskarshamn’s number #1 Nuclear Reactor, was shut down as tons of jellies (Aurelia aurita) clogged the cooling pipelines.
- 2005 Philippines. Jellyfish incapacitated 127 police officers who had waded chest-deep in seawater during a counterterrorism exercise.
- 2003/2004 Several jellyfish (Crambionella orsini) blooms in Iran, Oman and Pakistan affected fishing operations.
- 2003 Mar. Birka Power and desalination Plant in Muscat Oman was badly affected by jellyfish damaging intake screens.
- 2003 Al Ghubra Desalination Plant in Muscat Oman, 300 tonnes of jellyfish damaged intake screens causing a 50 per cent reduction in output.
- 2002 Oman. A large number of jellyfish blocked Oman's LNG seawater cooling system intake causing a shutdown. The shutdown costs the company about $7 million a day.
- 2001 Norway. 600 metric tons of salmon were killed by a jellyfish bloom (colonial jellyfish/siphonophores)
- 1997 Norway. 12,000 metric tons of salmon were killed by a jellyfish bloom (colonial jellyfish/siphonophores)
- 1999 Dec. The island of Luzon, home of the Philippine's’ capital Manilla, suffered a blackout due to jellyfish clogging up the intake pumps supplying water to cool the Sual Pangasinan coal-fired Power Plant. 40 million people were without electricity due to the jellyfish bloom and raised fears of a military coup
- 1989 4 million jellyfish were removed from Madras Atomic Power Station (MAPS) India. They weighed about 80 tons.
- 1984 St. Lucie Nuclear Plant in Florida (jellyfish clogged screens filtering ocean water used in the reactor cooling systems.)
- 1982 Black Sea, comb jellyfish cost $350M in the fishing industry
- 1937 Jellyfish shut down a power plant in Brisbane, Australia causing a widespread power outage.
Other Events & Notables
- Robert Condon, a jellyfish expert, says the big scientific question is how jellyfish populations will respond to climate change, though finding an answer will be difficult without more research. “There are approximately 500 jellyfish population experts in the world,” he says, compared with “tens of thousands of scientists in fisheries.” But now, with jellyfish threatening a multibillion-dollar industry, there’s significant incentive for aquaculture companies and scientists to spend the time and money to learn.
- Namibia: Jellyfish stopped sea-bed diamond mining. Jellyfish halted seafloor diamond mining off the coast of Namibia by gumming up sediment-removal systems.
- Ireland: Jellyfish interfere in salmon farming in Ireland.
- Oman: Last year, a large number of jellyfish blocked Oman LNG's seawater cooling system intake. If jellyfish cause a shutdown of Oman LNG, it could cost the company about $7 million a day.
- Dhofar Oman: Jellyfish posed a danger to the offshore oilfields.
- Caspian Sea: Sustainability of beluga caviar farming in the Caspian Sea, jellyfish are as destructive as they are abundant. Jellyfish are contributing to the commercial extinction of beluga sturgeon.
- Israel: It is estimated jellyfish cost $10 million a year in lost tourism. A study has found that jellyfish outbreaks in Israeli waters are responsible for a 3-10.5 percent decline in the number of seaside visits, resulting in an annual monetary loss of up to €6.2 million.
- Pakistan: Annually, about 2,500 metric tons (m. tons) of dried jellyfish is exported from Pakistan. Between 2005 and 2007 4,000 m. tons of jellyfish products were exported to China and Vietnam. ID238
- Japan/Scotland/Isreal: 2011, The year that jellyfish start taking this work seriously. Scotland and Japan both suffered attacks. In Israel, power plant workers had to remove 100 tons of jellyfish.
- Philippines: Jellyfish kill between 20 and 40 people a year in the Philippines alone
