finding fish

MIT researchers has developed a new way to find fish in the ocean. Using modified sonar, the device can map fish at much greater depths and distances than traditional techniques.

The NYTimes article says the device is a boon for conserving fish because scientists can use it to better understand the behaviour of shoals of fish. Let’s hope the technology is not so cheap that the big trawlers also can use it.

A movie of the modified sonar is here. Warning: it’s a BIIIG file.
