Global warming leads to an increase in jellyfish populations, which in turn alters marine ecosystems. The reduction in fish species that prey on jellyfish, along with the overfishing of small fish that compete with jellyfish for food and are often processed into fishmeal or feed, has caused jellyfish numbers to rise rapidly. The United Nations Food and Agriculture Organization (FAO) has pointed out that overfishing leading to jellyfish blooms is one of the reasons for the decline in fish catches in the Mediterranean and Black Seas. As predators, jellyfish consume fish larvae and eggs, further
