The Northwest is known for its seafood. Sweet, succulent spot prawns, briny oysters, mussels, salmon, halibut, cod and rockfish are all harvested from waters up and down the coast and in Puget Sound and the
USDA rules require that seafood be labeled with its country of origin, and with whether it is wild or farmed. But sometimes one label will list five or six countries for one pile of fillets, meaning that that species of fish sometimes comes from any of those countries. To find out where that particular batch of fish is from, you need to ask. The store is required to keep a record of where each day’s offering was harvested.
Another seafood decision is whether to buy wild or farmed. The sustainability of that choice depends on what you’re buying, and where it’s from. One of the biggest controversies in our area is about wild vs. farmed salmon. The farm that’s off the shores of Bainbridge Island is doing a better job than most – their pen density is low, the currents in the area are strong enough to flush away a lot of the waste that is generated, and the fish are fed a diet that is natural enough to get them into the fish case at Whole Foods. But Town & Country Markets never sells any farmed salmon, due to the many concerns that have been raised. For a host of reasons, including contaminants in the feed, pollution of the environment, risks to native salmon stocks, and the impact of cheap farmed fish on wild-salmon fishermen, farmed salmon is not the sustainable choice according to most sources.For wild-caught fish, how it’s caught can also be a factor. Cod and rockfish are often available at local markets. If caught by longline they are among the most sustainable fish choices. If trawl caught, they are among the worst. Again, you need to ask. I asked recently at Town & Country, and was told that 99% of the cod and rockfish (also sold as red snapper) they sell are longline caught, making both a very good choice. For other fisheries, farming is often more sustainable than wild. Tilapia, trout and sturgeon are a few of the fish that fall into this category.
There have been a lot of alarming headlines lately in regards to seafood; PCB’s in salmon, mercury in tuna, cholesterol in shrimp, etc. In his book Fish Forever, Paul Johnson suggests that chicken, dairy and beef contribute more PCB’s to our diet than any fish, that the sterols in shellfish can prevent the uptake of cholesterol rather than cause it, and that the type of mercury in fish may be less harmful than was thought. There’s not enough room here to review all of that information, but recent studies by the Harvard School of Public Health and the National Academy of Sciences conclude that the benefits of eating seafood outweigh the risks. There are many online resources to help you sort through the available information and make healthy choices.
As you can see, it’s not easy being green when it comes to fish. But there are resources out there to make it easier. One of the best is the Seafood Watch from
The Environmental Defense Fund has a website that has separate lists rating the eco-friendliness (with recipes) and health concerns of a long list of seafood items. The health section lists how many servings a month are safe for each type of seafood. Among the choices listed as being safe for adults to eat four or more times per month are halibut, rockfish, sablefish, sole and albacore tuna.
For a complete list of Washington seafood sources, visit Seasonal Cornucopia. It lists many local fishing vessels, shellfish farms, and fish mongers.
There's also a new book by Paul Johnson titled Fish Forever. It offers 422 pages of information about the sustainability of every fishery and the health benefits and concerns related to each. Johnson is also a chef, and he offers one of the best collections of seafood recipes I’ve ever seen. The book is available through the Kitsap Library system, and is also available through Eagle Harbor Books.
