Technology Scans Giant Fish Schools
rhettb writes "Employing a new technology, MIT engineers have studied the origins of a mass gathering of hundreds of millions of fish and their subsequent migration. This is the first time a mass migration of animals has been studied from beginning to end, according to their paper published in Science. Until now biologists have depended on theory rather than data from the field, employing computer simulations and experiments in the lab. The MIT engineers employed a new technology, Ocean Acoustic Waveguide Remote Sensing (OAWRS), to record the mass migrations in detail. Developed by Makris and his team in 2006, the OAWRS is able to take images of an area 62 miles (100 kilometers) in diameter every 75 seconds. The system relies on sending sound waves that locate objects by bouncing off of them."

MIT nerds use sonar to track fish, claim breakthrough.

This is a really interesting article. I am a Tuna fisherman and I would really like to know more about Tuna's behavior in an en-masse sense. I mean, we get "get on the fish" ok, but this sort of data would help fisherman understand how much fish can be caught, where to catch them and where not to (you want Tuna to reproduce so it would be nice to know where and when we should give a chance to re-grow.)
This is very promising to see that we are focusing research on a super-important part of our ecosystem, and this sort of thing will lead to a better understanding and I think better management of marine populations in general.
Cool. Better link:

This new technology will be installed on Chinese and Japanese fishing vessels to further depopulate the oceans and provide temporary low seafood prices. When asked about what they would do after emptying the ocean of fish, the Chinese spokesperson replied, "We're working on that."

Not an undersea, unexplained mass sponge migration?
And did they move more than a foot and a half?
The system relies on sending sound waves that locate objects by bouncing off of them.
Thank you! Simply saying it relied on SONAR would have left us all completely befuddled.
... would be so boring if they knew where the fish were.
I used to work on a commercial fishing vessel. With the the number of boats and the nets we used, the main reason we didn't take ALL the fish is that the ocean is so BIG. I've seen water churning with salmon which could not be located a short while later when fishing was allowed to begin.
If tools are now available to reliably track schools of fish in open waters, I think it's inevitable that the next step will be someone scooping them up in a net.
Great, another way to more efficiently destroy the oceans ecosystem.

Everyone should take only half a load? Yeah, that'll work great. Build in a huge incentive to cheat once prices are high. Your suggestion would lead to a highly exploitable environment, which people will exploit because that's what people do. Let's face it, "exploit environment" has been a successful strategy for about 4 billion years. Your gentlemen's agreement is essentially asking us to become a different species. Unlikely.
