Jellyfish Invasion

National Geographic Kids magazine
 The Sea of Japan has never been a very calming place. Sea monsters talked about, big scary fish, but this has never been expected. Giant Jellyfish have started to invade the seas of Japan even thought they are unwelcomed visitors there is nothing we can do about them. Know as the Nomura's jellyfish can weigh up to 450 pounds(204 kg) about the weight of an adult male lion. These “sea monsters” come from the coasts of China and North and South Korea, they were occasionally found in the Japanese Sea to feed on plankton or other small fish but suddenly they are invading in millions. Not only is this a problem for other fish, but for fisherman who keep on getting these giant jellyfish stuck into their nets and before they can be taken out they kill all the salmons and diverse fish found in the net causing the fishermen to have caught nothing. Nets breaking or being forced down are other common actions of the jellyfish. The reasoning for the jellyfish to have traveled from China to Japan, but one of the possibilities includes global warming causing the perfect breeding time. A second theory is that overfishing has caused all the fish from South Korean seas and Chinese seas to decrease so the jellyfish are trying to survive off of fish from Japanese seas. For now the only reasonable thing to do for the fishermen is to build expensive nets to keep the jellyfish out and maybe if any jellyfish caught some snacks can be created. So after all, all people can do for now is hope that the huge jellyfish won’t destroy the sea of Japan and fishermen can get back to work.
In my opinion I think jellyfish aren’t very attractive animals because all they do is just float around and either kill or eat fish. One of the steps we could do is capture some of the jellyfish and put them to display in some aquarium or sea world and hope that their “ancestors” won’t eat the whole sea. Or on the other hand, we could put sensors on the invertebrates which has already been tried, and see how these fish move and try to understand their movement. This article I read wasn’t exactly a current event with science behind it, but I chose it because it’s interesting to learn what is happening in the seas and not only what’s happening in our world.
