May 2, 2012 – I only eat anchovies with Caesar salad, and am rather fond of the tiny fish that add a bit of strong flavor to the romaine lettuce. I’m unusual for wanting to get even that close to the tiny, oily fish – sardines, anchovy, menhaden – that used to be a staple of regular American food. That’s why Julia Whitty’s recent article in Mother Jones in which she encourages consumers to pause before they “ take a bite of that sardine sandwich” was so surprising. You won’t find sardines anywhere on the list of the top 10 consumed seafoods – or do you? Here’s why eating more sardines directly would actually be good for the ocean:
1) The United States Pacific sardine fishery is not overfished. This may be surprising to people who are familiar with one of the most famous fisheries crashes of all time, the collapse of the Monterey (central California) sardine fishery, which was described by John Steinbeck in his book Cannery Row. Puzzlement over this collapse launched one of the most important long-term oceanographic investigations of all time, the California Cooperative Oceanic Fisheries Investigation, which continues to provide critical scientific information to this day. Over 50 years of investigation has shown that this crash actually WASN’T caused by overfishing – at least not directly.
Sardine and anchovy populations are actually tied directly to large-scale climatic conditions – if they’re favorable, there’s lots of fish. If they’re unfavorable, the fish crash. Overfishing may have exacerbate the crash and slowed recovery, but it probably didn’t cause it directly. Some researchers are predicting a similar sardine crash this year due to unfavorable climatic conditions similar to those seen before the late 1940s crash, and are encouraging managers to decrease sardine quotes in order to speed post-crash recovery. (Though this is controversial – see this response).
Historically, sardine & anchovy fisheries in other parts of the world, such as the South American anchoveta fishery (the biggest fishery in the world) are less well regulated. Overfishing in these ecosystems leads to no room for error – if there is the slightest change in the climate that causes the fish to reproduce less fast, the fishery crashes.
