It seems that many of Europe’s Mediterranean anchorages will be plagued by jellyfish once again this Summer. Whatever the reason (some blame over-fishing so lack of predators, others climate change), care should be taken before diving off the boat for that refreshing swim.

While Mediterranean resort areas will be hardest hit by the jellyfish plague this summer, there will also be high concentrations in the Baltic and North Seas, according to scientists.

This summer, marine biologists have already spotted swarms of jellyfish in the waters between Corsica and the French mainland. Cannes, France plans to install booms and nets around its most popular beaches to keep the jellyfish at bay, according to The Independent newspaper. Scientists have also started a jelly-watch off the Italian and Greek coasts to monitor the movements of the jellyfish, the newspaper reported.

Jellyfish are a problem because their tentacles used to paralyze prey, cause burning rashes when they come into contact with humans. Although the stings only cause minor discomfort, a variety of substances have been used to reduce the effects of jellyfish stings. Meat tenderizer, sugar, vinegar, plant juices, and sodium bicarbonate have all been used with varying degrees of success. If swelling and pain from more serious stings persist, prompt medical attention should be sought.
