USA - In order to show the changing global fish populations over the last 100 years and the affect of overfishing, a graduate student from New York University has come up with a novel interactive aquarium which presents the data in a unique visual way, writes Lucy Towers, TheFishSite Editor.

The 'web aquarium' can be seen by clicking here.

Graduate student, Sam Slover, presented his digital Aquarium at the NYU Interactive Telecommunications Programme Spring Show on Monday 20 May, where it was shown on a big plasma screen.

Mr Slover said the goal was to make a beautiful aquarium that allows people to interact with the data in a novel way.

Data for the project was provided by D. Villy Christensen and the University of British Columbia Fisheries Centre.

Through a regression study of 200+ datasets, researchers were able to estimate that, from 1910 to 2010, the world's big/predatory fished declined by 78 per cent, and the world's small/prey fish increased by 133 per cent.

The decline was slow (0.2 per cent per year) up to 1970, then severe during 1970-1990 (four per cent per year), and more slow since 1990 (2.9 per cent per year).
