A crime after an electric shock and then a burning feeling you know. Are there numbers in the worlds oceans increasing. And were going to have an insane reproductive capacity in a single jellyfish like this can produce 15000 eggs a day. Is this punishment for mankinds irresponsible actions. Our oceans are not well and jellyfish seem to be benefiting the explosion over their population just the unspoken monkey the jedi fish express to rescue them as a warning sign. The scientists the world over are studying jellyfish they hope to discover the secrets of jellyfish the medusas of the sea and their laboratories. Busy these are the waters off the coast of japan where back in 2002 something changed. A swarm of numerous jellyfish appeared veritable giants with a diameter of 2 meters. Numerous jellyfish with tentacles as thick as macaroni look like something from outer space not much is known about their life cycle. The german scientist cornelie ya suppose meets shinichi way from japan. Hes considered the leading expert of the international jellyfish seen. The aspers as a plankton expert and she wants to find out more about the giant jellyfish swarms in the sea of japan. They indicate that something is not right in the worlds oceans. The eerie giant jellyfish invasions are putting japanese fishermen at risk. Or professor way shows footage that looks like a scene from a horror film. When the the jedi fish comes in large numbers. They are net broken and the bruised and then the fisherman lose their huge money and its very difficult for the fisherman to do the solution but that may be the science will give some. Cute to do it. We scientists know way. The jedi fish come from and then theyre weird they are abundant so we would like to give certain information to the fisherman as early as possible and. We discovered that the large swarms of jellyfish came from china. And coastal waters there have been heavily impacted by human activity. That china sea is overfished and polluted. From their currents transport the 200 kilogram heavy jellyfish to the japanese coast. Barcelona. Experts are meeting at the jellyfish blooms symposium. The International Scientists are studying the seemingly unstoppable growth of the marine animals. But it remains an exotic research field. And not many marine biologists choose to specialize in jellyfish. Is the current explosion in jellyfish numbers linked to human activity. After. Plankton expert cornea gaspars in a colleagues discussed the issue at the symposium. Spurs has a Good International connections and shes hoping to find new leads. During her stay in barcelona she visits josep maria. The aquariums in his lab contain dozens of species of different ages. Jellyfish have inhabited our worlds oceans for. Over 600000000 years. For decades scientists overlooked jellyfish and fact creatures were actively avoided. By want to help jellyfish were typically ignored in research now theyre attracting a lot of attention because there are no harbors and close to our beaches people are noticing that there are a lot more jellyfish than before really but sadly we dont have systematic long term data to answer our questions if i thought. Jellyfish dont have a brain or a heart. They swim by contracting ring shaped muscles to create an underling motion that propels them forward their jelly matter bodies are kept together by 2 thin layers called epidermis and gastro dermis inside jellyfish have an essentially hollow space which is their gastro vascular cavity prey is guided from the tentacles by oral arms through the stomach tube and into the interior. Experts are discovering more and more of these animals remarkable skills the moon jellyfish or alien or rita is found in all the 7 seas and can form huge swarms gillie is especially worried by one mediterranean species the palagi not to look up which glows in the dark. Of. The biggest problem with a polite enough to lucca comes from its impact on the entire marine ecosystem there are predators they eat zooplankton and fish larvae but theyre also a problem for humans. Currents and when you bring them together in large swarms around our beaches i think contact with our skin causes severe burns. When the beaches have had to be repeatedly closed as a result of running a place. That beats as one of spains islands. This is where bartolome madi tour was a tour salo work theyre volunteers with the spanish Civil Protection office. They regularly visit the monitored beaches to determine the number of jellyfish incidents. Nobody here can predict when this one is occurring. Of the good of the bee not made any move and in early may we had a veritable genny fish invasion in the sea and on the beaches of the since then its been quiet. According to our lifeguards weve been having no more than 3 jellyfish incidents but they. Just hoping it will stay that way for the next season as well if you muddy a month but on top of. His colleague has a picture from the spring on his mobile. This is what a real jellyfish invasion in a pizza looks like. That or if you could be a shoo shoo shoo shoo shoo. The jellyfish could show up at any time. Jellyfish have one of the most toxic and differentiated cellular mechanisms in the Animal Kingdom lining their tentacles stinging cells. On contact they inject toxin into their victims. First it feels like a crime now but after an electric shock and then it burns out of the boat this give a little bit of thats why its better to stay in the water because its cooling. If you go out into the sun it burns and hurts much more. If you should call a jellyfish right away. But hell not because no one. Knows what hes talking about. He was stung by jellyfish just recently. He and his lifeguard colleagues swear by their 1st aid measure salt water with baking powder mixed in. Not fresh water because that would fuel the activity of the venomous capsules. The mix is always at hand at their observation post. In this day i was about that you know is that what this is so with baking soda you know its better than vinegar im a baking soda is alkaline or neutralize is the toxins in the jellyfish tentacles that hit when does the mom list and lessens the pain and yet the bottle that leave yet its definitely been a bit of a. Jellyfish. Sure not just a danger to humans in Northern Ireland they killed some 100000 salmon. An ocean current and carried the swarm to the salmon farm pushing millions of moth stingers into the cages. Jellyfish even cause power outages. When those surgeon officious coming in swarms there blocking our cooling system has cost them Nuclear Power plant in southern sweden was forced to shut down on the weekend after large amounts of jellyfish clocked up the pipes curing cooling water to deter banks. Yeah zones like that have given jellyfish a bad image some scientists exploit this saying jellyfish a bad by nature and that we have a real problem but that doesnt take into account the jellyfish populations always also lies there a year is when there are lots of jellyfish and he is when there are barely any thats normal for jellyfish and this is not my this is a crime to happen if. One earlier yesterday as wants to find out the truth about jellyfish. Shes been researching around the world for years. My professor hotter than my professor had mentioned small animals that could reproduce within 24 hours and that really sparked my interest i asked him about them and he said i should join a trip across the indian ocean to research the significance in the worlds oceans. I said yes and joined and thats how i became fascinated by them. Jellyfish get transported to europe and the ballast water of large container ships. For nearly a yes verse whos from hamburg has been observing the introduced species for almost 10 years. And not just in kiel on the baltic where she is currently working. Their population is growing dramatically a present as it is late summer. She can spot several jellyfish from the jetty. Its worth visiting these marine creatures under the surface. The search doesnt take long as expected they can be found on mars around the jetty. Its called the warty comb jelling or c walnut and strictly speaking its not a jellyfish. This creature doesnt have stinging cells unlike true jellyfish. This is why you aspers can touch them. The scientist has specialized in home joe in. Their natural home is the inland to the east coast of the u. S. For nearly a year aspers has established that this species is extremely adaptable and can reproduce at lightning speed. That is that since they have no food competitors here they can grow incredibly large take this one for example its 6070. 00 millimeters if you just take the body a specimen like this produces 15000. 00 eggs per day that can fertilize themselves we have to keep an eye on them although the salt content in the central baltic is too low for them but its a super habitat for reproducing. The port of kiel on the baltic is the starting point for scientific expeditions all around the world. Keels gale mar Helmholtz Center for Ocean Research is well known among researchers. Ya spurs was previously at the institute for Aquatic Resources at the Technical University of denmark. In 2006 marine biologists discovered the imported cone jelly species in the baltic. That was a shock. In the mediterranean the population had exploded and also caused huge damage to the black c. C. Ecosystem. How quickly can the warty come jelly conquer its new habitat. Is it a threat to the baltic to at 1st glance their fascinatingly beautiful. The a comb jellies shimmer and all the colors of the rainbow. Under the microscope it becomes clear why. Light refracts and all the spectral colors of the tiny transparent discs with which the animal moves around. But yeah spurs has made a frightening discovery. The migrants can cope so well with local conditions that its not just the adults that are reproducing but the young ones as well. Under ideal conditions and the lack of freshly hatched larva begins langue eggs and only a few days. Just 1st team spent months counting and observing to find out just how many eggs such larvae can produce. The oscars has shown that the ability of the warty come jelly to reproduce rapidly wherever it likes the conditions is largely linked to the species particular reproductive qualities. As i this isnt a native species it doesnt belong here so its important that we keep an eye on it so we know how its developing and whether its taking of the ecosystem. That would be disastrous. The baltic is home to fish such as cod and herring which are important for the fish market. Are the warty come jellies eating their young. Cornelia ya spruce performs an experiment to find out. She gives the jelly fish caught eggs larvae for food. The jellyfish doesnt eat the fish eggs they spit them out again. The opposite happens to the very young cod babies. The comb jelly laps them up. Many of us cannot take any to fish lava but mostly just those that is still in the yolk sent up they dont actively swim yet the others are to mobile get away from the jellyfish arms into the vehicle and continue up to snuff and of course. This means the warty come jellys could be dangerous. On board the Danish Research vessel donna biologist boston pewter conducts a jellyfish census 4 times a year. Are they posing a threat to the eggs and larvae of herring and cod. And it was bones get bitten that in these jellyfish is a natural habitat along the east coast of north and south america they are notorious for eating fish eggs and market fish i only laughing at 1st and thats of thats why we were worried when we 1st discovered this b. C. s back in 2007 here around born home because this is the main spawning area for baltic cod repeat this last office. Planted nets saved. The water column from the surface to just above the sea bed. If this is the net is called a bongo net because it looks like a bongo drum. We use this larger one mainly to capture fish eggs and larvae fish. So fine he says here this one catches all kinds of zooplankton and the baby bongo captures very small organisms. And jellyfish are caught by all of the nets. Making but defining. The captain of the down a is setting the course for the night. To be able to compare the results long term bastiaan who have their heads to the same coordinates each time only. If we zoom in again we can see the islands of gone home and fame on our bases are more in the eastern area. I thought wed start with the transact in the our kona basin and then well work our way over. To the Research Ship will travel along the set g. P. S. Coordinates for several nights. Captured zooplankton gathers in a catch back at the end of the net. And. The main thing were interested in is how many jelly fish we have in the samples and how many fish eggs and larvae fish. The data has set course on the next spacek. Meanwhile goober tends to his catch. A school of sticklebacks a speech thing on the zooplankton that he has yet to count. They have to be removed 1st. From. Under the microscope the different species of zooplankton can be identified. Tiny co parts along with fish eggs and larvae pray for jelly fish. At every station a measuring probe is lowered into the water. This determines the oxygen and salt content along with the temperature. Vertical profile of the Environmental Data appears on who their screen. The graphs indicate salty oxygen rich layers. It seems water from the north sea has found its way to the eastern baltic through the channels that suggests that the warty come jellies came here on this salt water current is here as well as i am says at the moment we dont believe this jellyfish has had a big impact on the fish populations here in the eastern baltic because it hasnt appeared on mass anywhere in the past and. In addition the jellyfish doesnt show up during the main cause spawning season light so that those boxes. So no reason for concern. Are nearly youngsters disagrees. Because the water column jellies came to europe into migration waves. The ones that appeared for the 1st time down here in the black sea a rich and aged from the gulf of mexico. Often go from mexico well hidden being the animals we have up here in the baltic theyve come from boston woods home that area. Boston thats been proved genetically and means that these were 2 completely distinct invasions. So what would happen if the warty come jellies from the black sea were introduced into the baltic. Killa come here they are found in large numbers in the southwest and baltic and in the kattegat between denmark and sweden but they havent conquered the majority of the baltic and. If we can show that the Southern Spaces has a different genetic repertoire and can cope with the lowest salt content then at the sudden once transferred north that could be a threat on the other hand we dont know what would happen if the southern and northern jellies were brought together we could get super potent hybrids or we could get hybrids that cant reproduce its a very exciting question thats really significant for the future of the baltic. But i dont. The scientist is bringing 40 com jellys from america the black sea and the baltic together in the lab. Over the next few years shell carry out evolutionary and breeding experiments funded by the e. U. As Marie Curie Program and the Danish Council for independent research for natural sciences. The plankton scientist hopes to find out whether the jellyfish will continue their advance and conquer new regions. In view. On the coaches or. Biologist probably among works for the observatory also. For must see me to use to meet an efficient scale. Beautiful organism a bit like flowers of the sea with their shape and tentacles and their almost lace like you. Might find them very pretty with a sort of zen way of life these organs. Your in the space the bins then. Anyone who speaks that positively about jellyfish must have a reason. The location of his office for example. Its from here that he decides whether its worth capturing a few of his research objects. Todays a good day. The last stinger is the dominant species in the mediterranean. Needs a few for his experiments in the laboratory. So let me. Just terrible as people think. Theyve been in the worlds oceans for more than 600000000 years sometimes say theyre in great abundance sometimes there are just a few of them but they always play an Important Role as predators in the ocean and they could be useful to us humans so we shouldnt think of them as being terrible even if there are sometimes too many of them we have to learn to live with them and occasionally use them. He. Has an unusual idea. He sucks up large quantities of slime released by the mob sting or when its lange its eggs and the moon jellyfish when it stressed. He kills the slime into test tubes. Then he injects water polluted with nano particles into the jellyfish line. Here. And the result the jellyfish slime causes the nano particles to clump together thus cleaning the polluted waters. At the prison and there are more and more nano particles these days in creams for example factories producing these nano particles must dispose of their waste water without polluting the environment. The jellyfish slime can be used to collect and gather all these nano particles into a bowl so that they can be gotten rid of easily in a low cost and environmentally friendly way its. Back to. Could this rescue the jellyfish its reputation. Of being a host is also seeking to understand jellyfish is dual potential on the north sea island the public well known for decades shes been researching the reproduction strategy of skippers 0 or more true jellyfish shes being helped by divers from the alfred begun to institute the team is going out to look for jellyfish polyps. Easier to see them if there are a lot of them of course looking for tentacles that move to and fro around corals is a good way to spot them they prefer to live on the underside of substrates which means you should always look from below that will give you a better chance of finding them. There are 5 north sea species floating under the ship apart from the home aphrodite compass jellyfish all the species have males and females. The sperm is released into the water and taken in by the females who carry the eggs. The fertilized eggs then turn into a jellyfish larva. The true jellyfish and then release these plan your way into the ocean. Thanks to tiny filaments the plan stays afloat until it comes across a smooth solid surface on to which it can attach itself. Once settled the plan yola develops into a polyp. Under very specific conditions these polyps will release many little jellyfish called a fire a. Fire up grow into full sized medusas. Then the cycle starts afresh. Its an extremely effective reproductive strategy. Polyps can survive for several years on the hard ground of the divers are to search. They dont have a skeleton so sandy soil moving around them would break them down thats why they need a hard substrate where they can settle safely sandy soil is no good to them or to an innocent looking something when the time were introducing had substrate sim places where they used to be only send in the shape of platforms or rigs for example. Meaning where increasing the places with can settle and develop into polyps and produce jellyfish ions and it. Offshore facilities are being built all over the world to satisfy our huge energy demands. The massive structures provide new underwater settlement areas for the polyps. Even shipping markers have been colonized along with concrete harbor structures and breakwaters cry a dive along this wall reveals just how popular treatment structures are for marine inhabitants. Every square centimeter is occupied. This diver is trying to find the polyps in this jungle on the harbors sheet piling. He takes a sample from a likely location. On her way back. Up since to a lions mane jelly fish. Fortunately hes wearing a full face mask otherwise he would have been badly stuck other talk but i hope its a female with love and so we can harvest the lava and rice polyps in the lab then we can study the polyps and find out when they produce jellyfish and im to what conditions. So they can fight if you dont find fault with the end of the thing. Run off half. The jellyfish in the sample are taken to the Lab Environmental conditions in the sea are changing. The reason is climate change. The increase in Greenhouse Gas concentrations is warming our atmosphere. The ocean absorbs the heat. In the north sea alone and encrease of 1. 7 degrees celsius has been measured Global Warming was also a subject of the jellyfish blooms symposium in barcelona. Yes frozen host meet Jennifer Purcell shes been researching the dynamic between jellyfish populations and their policies for the past 40 years. When you give them higher temperatures they produce more jellyfish. Dramatically more jellyfish than they do in the cooler waters. Increasing air pollution as a result of industry and traffic is leaving its mark. Theres too much Carbon Dioxide in the atmosphere since the Industrial Revolution the worlds oceans have absorbed half of the Carbon Dioxide. The gas dissolves in the oceans reducing their ph values. Our oceans are becoming more acidic. All organisms with a calcium based skeleton are in danger because the acidic water dissolves limestone. Jellyfish dont have a skeleton therefore the acidification of the oceans isnt a problem for them they survive. Jennifer herself describes further negative effects. The high amount of fertilizer used in agricultural leads to nutrients getting into the oceans via groundwater rivers. This causes phytoplankton blooms. Tiny algae which form huge carpets as can be seen from space. This bench to pull fodder produces all the more zooplankton. Its made up of microscopically small animals and fish larvae. This is what jellyfish feed on allowing them to reproduce in great numbers this is causing you trophic conditions with lots of nutrients in the water it leads to low oxygen levels and. Jellyfish are very tolerant of those conditions. At the same time the fishing industry has depleted fish populations and fish are the main food competitors of jellyfish. Fishing in the baltic and the Danish Research boat down there. Even a cursory glance tells the scientists but there are too few female caught able to spawn. Theyve been overfished by the baltic fishing fleets. The danes are counting on behalf of the International Council for the exploration of the sea which monitors 110. 00 fish species around the world. Their data is included in the annual recommendation for e. U. Fishing quotas. Both the young fish and the small schooling fishes like herring are eating those oh plankton the little tiny animals swim around in the water so both of those are being consumed by jellyfish and fish then youre taking away the fish so that leaves more food for the jellyfish to eat. Back on how the girl and sabina holsters on her way to the lab the breakwaters made of tetrapods like a red carpet with a jellyfish larvae she finds plastic rubbish on the beach. Millions of tons of Plastic Waste find their way into the oceans around the world. Currents keep the plastic adrift in the water for a long time and they too are welcome settlements for polyps. In the lab post examines the sample brought in by the divers. She finds what she was expecting. There amongst the algae barnacles and moss animals the branching jellyfish polyps of the anthem a doozy. Biological institute has been sending a monitoring boat out to sea almost daily since 1962. It is one of the longest running long term marine Data Collection programs. The scientists collect water and plankton samples. If environmental conditions change could impact the composition of ocean plankton a change jellyfish might benefit from living through that we know that jellyfish polyps are very resistant to changes in the environment and that means that the polyps survive environmental conditions that other organisms cannot believe that this man needs to believe on. The atlantic. The circus so see which is situated far off the coast of north america. Danish Research Vessel donna was on a deal expedition. For nearly a aspers does not agree with the negative image jellyfish have together with an International Team of maritime biologists plankton experts she wants to prove they play an enormously Important Role in the food chain for example for the endangered european ill the thai ruin a surprise that is becoming more expensive meals are actually at risk of extinction one possible connection that nobody is really making is that jellyfish could be a potential Building Block in the food chain without them we might have no more to wait and you couldnt get up to camp kind of an island on. The net for catching eel larvae is raised from a depth of 250 meters. The 1st glance proves that there are many species of gelatinous plankton organisms here. Amongst them the scientists discover the mysterious ill larvae that hatch here in the sargasso sea. One this size wouldnt survive in an aqua culture because nobody knows what these baby seals eat. Thats why no one has ever been able to breed european eels. The multi net is lifted on board. It gathers samples from several depths between 0 and 400 meters. Plankton experts cornelia ya spruce skills are needed. After hours of rinsing counting classifying. It becomes clear which organisms contribute to the food chain out here stark aso see. Yeah funny. We catch small in love and cut them open we remove the stomach in his molecular methods to determine what they eat jellyfish dont have skeletons as a result they get digested immediately that makes it really hard to use normal methods like microscopes to find traces of such organisms but now we have molecular methods so that we can find out what gelatinous organisms are in the stomachs we also examine which gelatinous organisms are in the water. And then hopefully we can match the 2. Maybe bidens a hunter mets are. Doing well larvae eat jellyfish. Proving that is difficult. The meticulous counting job on board is only the 1st step for the researchers. Analyzing the data will take several years only then will the results be ready for publication. Are jellyfish barter for the fish we eat establishing that would be a breakthrough for science. And the key not just for saving the european deal but also other endangered fish species. The jellyfish blooms symposium is an important event for exchange between scientists. Jellyfish research is still in its infancy. And uniform Research Methods as have been established in fishery biology are lacking. I think its a really nice sign that there are so many young people involved now thats a very positive sign so is there a lot of postdocs and mass of students involved that that means that theres an interest and growing interest and that is what has been looking into past years i think we. Seeing the 2 final twi there is some growing population a some point on the planet we find occasions about of course it in its longest 3 days the decatur street is all youve been very strong experimental street is that falls a moment i feel lucky and there is a lot of money touring. Monitoring programs that are started that need to be continued to air radio understand what is going on. Whats clear is that the medulla are an important indicator of the decline of the oceans. A problem caused by humans. Of course the jellyfish has no words to say theyre human beings but the explosion of their population is just the unspoken language. That the fish the jellyfish expressed through us human beings as a warning sign the mysterious world of jellyfish theyve been around for over 600000000 years making them the oldest marine inhabitants on our planet so far there has never been a jellyfish takeover but the creatures unusual qualities continue to enrich the diversity in our ocean. The time is money. C o 2 content into music. And c o 2 content the us into a hot tub. Its found claims vehicles clothes and food plants and its cooking our planet its high time to redeem c o 2.
