Jellyfish Chipper

Author: Hugh Bollinger/Friday, October 4, 2013/Categories: natural history, video, sustainability, environment

Jellyfish come in all shapes, sizes, and can be both beautiful and deadly. Anyone who has witnessed the wonder on the faces of both kids and adults watching "moon-jellies" at an aquarium, know the amazement created by these ethereal sea creatures.

But when massive jellyfish blooms occur, the mollusks can be very destructive environmentally. Causes vary, but the most common ones include overfishing of jellyfish predators, water pollution, and decline in dissolved oxygen caused by algal blooms. The environmental group, Jelly Watch , monitors these blooms on a worldwide basis.

A device has now been developed in Korea to control masses of jellyfish that have clogged bays, fisherman's nets, and depleted fish stocks by eating their eggs. Called the Jellyfish Elimination Robotic Swarm or JEROS, the sea roaming bots shred the invasive jellies like a wood chipper. A short video shows how:

According to Korean researchers, The first version of the robotic "jellyfish terminator" was able to destroy 900 pounds of the creatures per hour while An improved model will clear-up nearly 2,000 pounds of the invasive jellies in the same time.

There were no comments about restoring fish and sea turtle stocks which used to control the jellyfish naturally.
