28 May The hidden cost of farmed fish
As ocean stocks dwindle, humanity turns increasingly to farmed fish. But does this actually make matters worse? Graphic artist Nigel Upchurch thinks so:
It matters which farmed fish you’re eating, as some species consume more than others. Salmon is the worst, as this table, from a paper by Albert G.J. Tacon and Marc Metian of the University of Hawaii, demonstrates:
The red arcs represent wild fish inputs, the yellow arcs farmed fish output. The numbers inside the circles show the ratio between the two. Numbers greater than one mean more wild fish is consumed than farmed fish produced. Upchurch provides additional fine print.
