Jellyfish Bloom

Increasing blooms of jellyfish around the world may be triggered by the construction of offshore structures such as gas and oil platforms and wind farms.

The structures appear to provide jellyfish polyps with something to attach to, increasing chances of survival.

Researchers found that the more-frequent moon jellyfish blooms in the Adriatic corresponded to a rise in its number of gas platforms.

A construction boom in waters off China could be responsible for the massive increase in Nemopilema nomurai — one of the world’s largest jellyfish and a growing nuisance to fishermen.
