They are comparing apples with oranges in that chart. Cultured algae, molluscs, crustaceans, echinoderms, and cultured fish versus... wild fish. So they are removing wild molluscs, crustaceans, echinoderms and wild algae from one side of the equation in an article that focus in the message that that part has decreased. Lying with statistics. If we compare wild fish against farmed fish only, the result would be really different. And there is pirate fishing also. Some companies under-report a percentage of their captures routinely, to hide that they fish more than are allowed to. Not so easy to do in sea farms when you can't produce more than the space assigned to you.
