People hear how fish stocks are being depleted due to overfishing, but it's difficult to understand the real magnitude of this decline.

The Nature of Overfishing is a Web aquarium that tells the tale of the world's fish populations over the last 100 years. While there was once big "predatory" fish and small "prey" fish in healthy proportions, overfishing has decimated our ocean's big fish (i.e. the ones humans catch and eat) and left small fish populations overly abundant. The decline was modest until 1970, and then took a sharp and drastic turn for the worst. This digital aquarium is a data story, presenting the information visually. The data comes directly from a regression analysis by Dr. Villy Christensen and the renowned UBC Fisheries Centre
