fishing down the food chain
This is the second in a series of ocean infographics by artist Don Foley. These infographics also appear in Oceana board member Ted Dansonâ€™s book, â€śOceana: Our Endangered Oceans and What We Can Do to Save Them.â€ť
With shark week fast approaching, how about a shark-related infographic to whet your appetite?
Todayâ€™s infographic illustrates how overfishing fundamentally alters ocean ecosystems, leading to fewer and smaller fish over time.
If overfishing isnâ€™t stopped, the largest fish like sharks, tuna, cod, and salmon eventually run out and overfishing expands to previously untargeted, smaller speÂcies, some of which were considered undesirable. As a result, the world catch is now primarily made up of small fish like pollock rather than large predators like grouper, and this shift to smaller and smaller species over time is called â€śfishing down the food chain.â€ť
