have to keep an eye on them although the salt content in the central baltic is too low for them but it s a super habitat for reproducing. the port of kiel on the baltic is the starting point for scientific expeditions all around the world. 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 sees ecosystem. how quickly can the warty come jelly conquer its new habitat. is it
jellyfish has had a big impact on the fish populations here in the eastern baltic because it hasn t appeared on mass anywhere for coming today it will. also be a minute dition the jellyfish doesn t show up during the main cod spawning season. like say that those bosses. so no reason for concern. for nearly a youngsters disagree. because the warty come jelly s came to europe into migration waves. the ones that appeared for the 1st time down here in the black sea a rich and i did from the gulf of mexico he got from mexico well him being the animals we have up here in the baltic they ve come from boston woods home that area . that s been proved genetically and means that these were 2 completely distinct invasions. so what would happen if the warty come jellies from
actively swim yet the others are to mobile get away from the jellyfish arms into the vehicle issue and coming up to 7. this means the warty come jelly s could be dangerous. on board the danish research vessel donna biologist boss john cougar conducts a jellyfish census 4 times a year. are they posing a threat to the eggs and larvae of herring in cod. and it was supposed to be in there and these jellyfish is a natural habitat along the east coast of north and south america they are notorious for eating fish eggs and marking fish eye on the laughing rest of us have that s 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. this os that offers. plenty nets saved. the water column from the surface to just
