Few seafood lovers can keep from salivating over a gorgeous piece of bluefin tuna. That’s the problem: There are too many seafood lovers and not enough bluefin. But Pacific albacore, a smaller tuna best known as “chunk white” in cans, happens to be plentiful and relatively cheap. Turn the other end of the food chain and you’ll find smelt, sardines and anchovies. Most people think of sardines or anchovies as bait – and they are. But both fish are phenomenal eaten fresh, and Monterey’s sardine fishery has returned with a vengeance after collapsing a generation ago.

Eating sustainably does not mean eating poorly, and to prove it Tom Worthington of the Monterey Fish Market is bringing the best minds in sustainable fishing to the Slow Food Nation event this Labor Day weekend.

Fresh sardines, Alaskan halibut, Dungeness crab – all are world-class foods that are sustainably managed. Worthington says about 30 Bay Area chefs will be using these regional seafoods to offer Slow Food Nation visitors a taste of just how good eating sustainable seafood can be.

But Worthington says the food is intended to draw attention to the dilemmas that face every kind of marine ecosystem, from estuaries to bays to the oceanic fisheries. As it happens, Northern California has examples of each environment, and all are taking a beating from a combination of pollution, habitat loss and fishing pressure.

“Most people have no real clue about the environment from which we obtain fish,” said Worthington. “In essence, I’m telling people what our ‘farm’ looks like, using ‘farm’ as a metaphor…I don’t think a lot of people have an idea about what wild fish is – we’re talking about wild ecosystems that feed us.”

Normally a highlight of a local seafood show would be king salmon from the Sacramento River system – historically the largest king salmon run on the West Coast. But salmon numbers are so depleted this year the state has banned commercial fishing.
