Robot protect sturgeon

Atlantic sturgeon is considered one of the oldest fish in the world, they can live up to 60 years, reaching length 4.6m and weighing 360kg. The sturgeon is threatened by over-fishing, especially when salted sturgeon is considered special.

To protect the sturgeon from extinction by inadvertent fishing by fishermen, scientists at the University of Delaware (US) have used satellites and r oodles diving called Otis . In recent years natural sturgeons have been tagged and through which scientists track their migration routes.

Scientists now use satellite data to analyze where they live, including sea temperature, chlorophyll levels, and so on. To determine exactly where they live, Otis Marine Robot will collect data remotely through the above criteria, from which the warning system will notify the fisherman temporarily leaving the area.

In a three-month implementation mission, Otis measured salinity, dissolved oxygen levels, chlorophyll, and flow, and coordinated with the data obtained through the tag attached to locate the sturgeon. According to the journal Gizmag, in the last three weeks scientists have found 10 Atlantic sturgeon.
