UN Scientists Warn of Jellyfish Overpopulation

Unchecked, will drive down fish numbers

|

The United Nations on Thursday warned overfishing in the Mediterranean was boosting jellyfish, which reduce stocks further and it called for jellyfish to be used in food, medicine and cosmetics.

A study by the UN's Food and Agriculture Organisation (FAO) in Rome said overfishing had increased the number of jellyfish because it had removed their main predators from the food chain.

In a "vicious circle", the jellyfish then feed on fish larvae and young fish "and further reduce the resilience of fish populations," the report said.
