Aquaculture today is a larger source of meat then beef following a long rise to the top and much leapfrogging, says Dr McGill, who is head of Southeast Asia for agribusiness consultancy LMC. “In 1961, there was practically no farmed fish,” McGill says. “Back then, the world was eating meat, with beef at the most important source of meat at just above 30m tons consumed globally. Then in the late 1970s pork became more important than beef. By the mid 1990s poultry had overtaken beef.
