The world is eating more fish than ever before. But we’re not really catching many more wild fish than we did in the mid-1990s.

How is that possible? Fish farming.

Basically all of the increase in the world’s fish production over the past two decades has come from aquaculture — including fish farms, shrimp farms, oyster farms, and so on. That’s according to a new report on fisheries and aquaculture from the UN’s Food and Agriculture Organization (FAO):

There are a couple of key points from the report:

1) People eat twice as much fish today as they did in the 1960s. Back in the 1960s, the average person ate about 22 pounds of fish per year. Today, the average person eats about 42 pounds of fish per year.

2) But we’re not really catching much more fish. Humans caught 91.3 million tons of fish from the oceans and inland waters in 2012. While that’s the second-highest level on record, it’s also a bit below 2011 levels and not significantly different from 2007 levels. Wild catches haven’t really increased since the mid-1990s.

The trends in wild catches vary from region to region. In the Northwest and Central Pacific, fishermen are catching more fish than ever.

But in the North Atlantic and Mediterranean and Black Sea, the number of fish being caught declined in 2011 and 2012. Some of that might be because of depletion due to overfishing, but it also may be due to new fishing restrictions aimed at rebuilding stocks.

3) So aquaculture is filling in the gap. Aquaculture — which includes fish farms — now supplies 42 percent of the world’s fish production. And that number keeps increasing each year.

The boom in fish farming is a big reason why fish consumption keeps rising even though fisheries have basically flatlined. In fast-growing Asia, for instance, fish farms have outproduced wild catches since 2008 — and aquaculture now provides 54 percent of all fish.

The FAO report says there’s little evidence that farmed fish are any less nutritious, on average, than wild fish — and tend to be an “excellent alternative in a healthy diet.” As such, the report predicts that aquaculture will keep growing in the future…
