Invasion of giant jellyfish in Japanese waters

Nomura, Japan. Huge jellyfish ocean, reaching 2 meters in diameter and weighing
up to £ 300 (ex. 136 kg) once again attacked the coast of Japan.
Such invasion invertebrates primarily harm the fishing industry of the country.
Giant jellyfish not only damage the fishing nets, they are just as harmful to fish,
striking for its poisonous tentacles and make it inedible.

Many cooperatives have suspended commercial fishing.
