Fish & Chips
I don't know why there are so many stories about tracking animals these days. After telling you about how satellites are used to track pigeons and koalas, CIO Magazine reports that computer tags are used to track Pacific coast salmon.

The salmon have two homes, the river home and the ocean one, largely unknown. So, as part of the Pacific Ocean Salmon Tracking (POST) project, computer chips called acoustic tags have been implanted into 1,200 young salmon. And receivers have been placed on more than 120 kilometers of seabed around Vancouver Island. When a tagged fish passed near a listening station, the tag emits its serial number and data such as position, speed and direction is collected by the receiver.

With this data, it will be possible to improve the sustainable use of Pacific salmon resources. You'll find more details, references and pictures in this overview.
