Chocolate covered strawberries, and marshmallows!

Whatever was keeping their population in balance is obviously missing in much of the oceans today. Whatever it is, we need to replace it. I am not a marine biologist, but I do understand the balance of nature in ecosystems. We eliminate or lose one link in the chain to the detriment of the system.

Get a good PR firm to publicize the fact that catching a jellyfish and annihilating them is a "cool" thing to do..that all the "hot" people do it! Voila! Jellyfish gone! :)

We can probably stop fishing for things that are an odd number of steps up the food chain from jellyfish.

Where is the proof that jellyfish are proliferating?

who knows...all populations ebb and flow.. if it gets to be a serious problem..im sure commercial fishermen will develop a market for jellied jelly fish. i know they eat them in asia

The plastic bags that end up in the ocean will eventually scoop them all up!

employ a giant jelly fish vacuum and render the neurotoxins into something helpful for all mankind.

We should probably start fishing at a sustainable level to start with, and maybe to start protecting sea turtles from natural predation when they are babies dashing for the surf. How about farming sea turtles?

Market them as a food fish and convince the population at large that they are good to eat.

Off-shore drilling should do the job.

Address the problem, which seems to be overfishing and killing off too many of the Jellyfish's natural preditors. Article - According to a BBC report, marine biologists are blaming hot, dry weather and overfishing for the increase in jellyfish numbers. Hot weather has warmed the coastal waters to higher-than-normal temperatures, with low river flows resulting in unusually high salinities that bring offshore jellyfish closer to the coast. Rampant overfishing in the Mediterranean has removed many of the jellyfishes’ key predators. As commercially important fish such as herring and sardines dwindle due to overfishing, jellyfish are flourishing in their stead. According to the environmental group Oceana, more than 10 jellyfish have been found per square metre in some areas off the Spanish coast. Giant Jellies Meanwhile, in Japan, enormous numbers of giant Nomura's jellyfish, or Echizen kurage, have appeared off that country’s coast. While their presence poses a mystery to scientists, the fishing industry is struggling to rid its nets of the enormous jellies, which can measure up to two metres in diameter and weight up to 200 kilograms. In some areas of Japan, jelly populations have increased a hundredfold. pic of the beasties - http://news.nationalgeographic.com/.../...19_jellyfish.html And a video of one - http://www.educatedearth.net/video.php Japanese researchers have suggested that the jellyfish reproduce in South Korean or Chinese waters, and then drift to Japan on currents. Some are blaming heavy rains in China this summer, which increased freshwater flow out of rivers such as the Yangtze, and may have propelled the jellies toward Japan. Overfishing in the region may also be to blame, having removed key predators such as sea turtles and tuna. Scientists at the National Institute for Environmental Studies in Japan have reported a three-year plan to study jellyfish populations at China’s Three Gorges Dam, in order to determine whether the controversial dam project has promoted out-of-control jellyfish growth. According to a report on DiscoveryChannel.ca, the scientists are concerned that the dam project – which has submerged massive areas of land and forced millions of people to relocate – is trapping silicon behind the dam and preventing it from reaching the mouth of the Yangtze River, where the jellyfish typically breed. Silicon promotes the growth of diatoms, a type of phytoplankton that forms the basis of the marine food chain. But the trapped diatoms sink to the bottom of the dam, and as a result, the nutrients that they usually carry to the sea (such as phosphorus and nitrogen) remain in the upper layers of the water. An increase in these available nutrients provides food for other, more damaging species of plankton and algae to move in – including jellyfish and toxic red tide. Jelly populations have spiked in the past, but recent outbreaks in 2002, 2003 and 2005 have prompted the government to seriously investigate the cause. Amidst strained relationships between Japan and its two neighbours, however, no country is willing to accept blame for the bumper crop of jellies. Fishing Down the Food Web Off the Namibian coast of Africa, the impact of heavy fishing in the Atlantic Ocean has resulted in another jellyfish explosion. Scientists at the University of St Andrews in Scotland have found that the weight of jellyfish in Benguela now by far exceeds that of the once prolific commercially important fish stock in the area. Led by Dr Andrew Brierley, the researchers used scientific echosounders to sample jellyfish and fish in an area of over 30,000 nautical miles along the Namibian shelf, between the borders of Angola and South Africa, where striking changes in numbers of the large jellyfish species Chrysaora hysoscella and Aequorea forskalea have become been reported more and more frequently. “In the past, this region has offered abundant fish stocks, thanks largely to the fact that it is served by cool, nutrient-rich upwelling waters,” said Dr. Brierly, who is leader of the University’s Pelagic Ecology Research Group. “The fish stocks, including sardines and anchovies, have been heavily exploited since the 1960’s, and have been strongly depleted in the process. Because fish and jellyfish essentially compete for similar food resources, a dramatic decline in fish populations could theoretically contribute to a substantial increase in the abundance of jellyfish. This type of shift has been predicted as a consequence of ‘fishing down the food web’.” Dr Brierley’s team estimates the total biomass of jellyfish in the region to be 12.2 million metric tons, most of which is due to A. forskalea. The biomass of fish in the region accounts for only 3.6 million metric tons. The increased jellyfish population in northern Benguela now not only outnumbers fish in the region, but is now so large that it ‘significantly interferes’ with fishing operations and industrial water uptake systems. Jellyfish have few natural predators. Because they prey on fish eggs and juvenile fishes, Dr. Brierly notes that once jellyfish become established in an ecosystem, it may be very difficult to revert to the previous fish-dominated ecosystem. The study appears in the 12th July issue of the journal Current Biology. Source: http://www.vanaqua.org/aquanew/fullnews.php?id=2089

BY humans changing their destructive ways and doing something about global-warming, fertilizer runoff into the seas, and especially depleting the fishstocks of the oceans.

By leaving the oceans alone until they normalize.
