Unmanned 'Terminator' Robots Kill Jellyfish 149

First time accepted submitter starr802 writes "Scientists from the Korea Advanced Institute of Science and Technology in Daejeon, South Korea, have developed a 'jellyfish terminator' robot set out to detect the marine coelenterate and kill it. Scientists started developing the robots three years ago after South Korea experienced jellyfish attacks along its southwest coast, where they clogged fishing nets and ate fish eggs and plankton, Discovery News reports. The Jellyfish Elimination Robotic Swarm or JEROS has two motors that let it move forward, backwards and rotate at 360 degrees." In related news, the Oskarshamn nuclear plant in southeastern Sweden was shut down recently after moon jellyfish overwhelmed the screens and filters in cooling pipes."

      Dear mods:

      The parent post does not count as flamebait, quite the opposite, he has very bluntly and articulately identified the root cause of the current overabundance of jellyfish.

      Humans can still fish (although we really should limit ourselves to recreational fishing, and stick with farmed fish for food production). But modern supertrawlers don't just decimate fish populations, they catch the entire population in an area.

      You want to get rid of jellyfish, get rid of these floating offenses to biodiversity by any means possible. Ban them, sink them, make their crew pariahs. If the fish come back, the jellyfish will vanish.

      Yes, it would make perfect sense to replace hunting at sea with farming, just as we did on land millennia ago, so that our use of seafood could become sustainable. So why does the Luddite lobby oppose every kind of fish farming, preferring to remain romantically identified with wild catch? When I question them on this, all I get is that one old talking point "Because the first attempts at fish farming involved crappy feed, overcrowding and disease, God said it has to be this way forever!"

      Heh heh heh. Overfishing. I mean, that's part of the problem, but did you forget about acidification? (Let's just gloss over nuclear currents for a moment.) The significant sea creatures that can tolerate it gracefully are brittle stars [nature.com] and jellyfish [msn.com]. Algae will do okay as well, but kelp won't -- the increased acidification promotes algae that competes with it. So you get a big soup of stars, jellies, and algae. Mmmmmmmm good.

      As for what the jellyfish become food for, it's everything below it, like always. Unless you have a problem with bottom-dwellers there's no reason to complain about that. The real issue is what we're doing to our biosphere that's causing these problems.

      By all means, stop overfishing, HAHAHAHA. But that won't stop this.

      • by h4rr4r (612664)

        It would help. There are large predatory fish that eat jellyfish, they might suffer due acidification anyway, but fishing them to extinction is not helping.

        BlueFin Tuna needs to be added to CITES.

    • Wouldn't it make more sense to fix the root cause of this problem, that is, overfishing?

      It's that simple, is it? People can just stop eating?

      Why are humans the only species that doesn't get to compete?

      • by cusco (717999)

        You don't seem to understand the concept of 'overfishing'. It's a short-term solution to feeding people, not a long term survival strategy. Overfish a species badly enough and the fishery collapses and doesn't recover, like the Peruvian anchovy fishery. Almost no one eats Humbolt Current anchovies now, because there aren't enough to be worth catching and there probably won't be again for decades. It's not like this was unprecedented, the same thing happened in California just a couple decades earlier.

        • Anchovies and sardines aren't as susceptible to overfishing as larger fish. Their fast reproductive cycle allows them to recover quite fast if conditions are right. Their populations are linked to ocean temperature, which is also something humans have an effect on. You can learn more about it here [noaa.gov]
