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."

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.
