you have spread out this year in large quantities much earlier than usual in the Baltic sea and are particularly large: jellyfish. “This is a very good jellyfish year,” said biological oceanographer Cornelia Jaspers.
“three weeks Ago we have, especially in eckernförde, a very dense volume on the ears, jellyfish Bay, occasional jellyfish and invasive ctenophores observed.” The latter appeared here, usually in the late summer of this year but already in may.
Very much the salt-rich water in the Baltic sea attracts jellyfish to
“In Winter a lot of salt poured-rich water from the North sea and the Kattegat in the South-Western Baltic sea,” said Jaspers, who conducts research at the Geomar Helmholtz centre for ocean research in Kiel and the Technical University in Copenhagen. The high salt content have obviously led to the strong emergence of the jellyfish, which had been observed in 2006 for the first time in these regions. “In the case of low salt content, the jellyfish Mnemiopsis leidyi is not to reproduce the German sea walnut,.” This jellyfish is not poisonous and thus harmless to humans – but it eats local fish food.
in Addition, the warm Winter had encouraged the existence of the Ribs and also the domestic ears, jellyfish, said Jaspers. Instead of two to three degrees in the last 40 years – was the water, this time to the five degrees warm. Because jellyfish also eat drifting organisms (Zooplankton), you can also contribute to oxygen loss. This invasive Ctenophore was gone for three years, from 2011 to 2013, after severe winters, the Baltic sea and, in 2014, after a very mild Winter, come back, with the salt water from the North sea.

And what actually makes the jellyfish by the name of Blackfordia virginica, which was seen in 2014 for the first time in the North sea-Baltic canal? “We have you there once again and earlier than usually observed,” said Jaspers. The brackish Lenart water loving Torment could also live well with a low salt content and, consequently, an additional competitor for Food for fish in the Baltic sea, if they should establish themselves there, and in order to be a real Problem. “So far, we have discovered the Blackfordia only sporadically in the Bay of Kiel,” said Jaspers. More to the current area of distribution are to be clarified by an Expedition in September.
“jellyfish are part of normal life,” said Jaspers on the sea animals, which are not leisure just popular and of which some species are also very toxic and dangerous to humans. “There you are, already since 550 million years ago, the original living being.” The endangered European eel, for example, in the Sargasso sea depends on to eat jellyfish. “What is the key role of jellyfish in total in the Ecosystem, is an exciting question, which is still largely unresolved.”
Poisonous jellyfish touched: So you respond to it properly
For people-to-people encounters with jellyfish is not always pleasant. Who has come with a toxic specimen in contact, you should rinse the affected area with fresh water or alcohol. Still tentacle remnants should be on the body, moisten it with salt water, but it is still with the shaving foam. Scrape off the residue afterwards with a blunt object, for example, a credit card, be careful. Then you dust a fine Sand over the irritated skin.
Also, you should be cool with a cool pack or Gel from the pharmacy. Important in all these steps: do Not RUB! The can stimulate the tentacles to more venom or the venom deeper into the skin to carry. You will have strong or long-lasting symptoms persist, you should consult a doctor.
