Giant jellyfish shed fish vessels

A 10-ton fishing vessel has just been capsized in the east of the Japanese sea by giant jellyfish.

The ship, named Diasan Shinsho-maru, sank near Chiba, Honshu island, when three fishermen on it were trying to pull the trawl. There are dozens of giant Nomura jellyfish in the net (each can weigh up to 200 kg). Giant jellyfish appear abundantly in Japanese waters this year.

Reported by Mainichi, three fishermen on the ship fell into the sea when the boat turned over, but they were rescued by another ship. The Japanese coast guard said that the sky was clear and the sea was calm at the time of the accident.

Nomura jellyfish is one of the largest jellyfish in the world. Their body diameter can be up to 2 m. The last time Nomura jelly invaded Japanese waters was in the summer of 2005. Seafoods become toxic if eaten by jellyfish. They also damage fish nets and can cause injury to fishermen.

Scientists know very little about the Nomura jellyfish. So it is impossible to explain why there were tens of thousands of people in Japan in the sea, but last year there were no children. In 2007, officials received 15,500 notices about property damage caused by giant jellyfish.

Many experts believe that giant jellyfish regularly visit Japanese waters in the last few years due to their reduced number of enemies. Among the animals that eat jellyfish there are sea turtles and some types of fish.
