The increasing number of Mnemiosis jellyfish blooms are harming not only the fishing industry but also the power industry.
Mnemiosis jellyfish can hatch over 40,000 eggs every day. These blooms feed on the larvae and eggs of fishes, especially from those native from the Black Sea, which has led to a shrinking in the total amount of fish. The reduction caused by this type of jellyfish is costing the fishing industries millions of dollars.
At the same time, the jellyfish swarms are affecting power plants in countries such as Japan, Israel, and Scotland. This is due to them congesting on the power plants, thus causing people to lose electricity.
Recently, a possible solution has appeared. The Bereo jellyfish, a different species that feeds on the Mnemiopsis jellyfish, has entered the Black Sea's ecosystem and created a new balance. But scientists fear that introducing a new speacies in other seas might cause negative consequences for their ecosystems.
