Algae in Lake Tai May Be Useful

November 1, 2007

Consuming omega-3 fatty acids in fish can benefit the brain development. However, there’s some concern about mercury in fish. Well, it turns out that you can get omega-3s without ever eating fish, which is a good news not only for vegetarians but also for Lake Tai (See this post).

From NPR, “Getting Brain Food Straight from the Source

The Martek Biosciences Corporation manufactures DHA from algae, which is where fish get their DHA, explains J. Casey Lippmeier, Martek’s senior scientist.The algae are eaten by smaller marine life such as copepods, “and those are eaten by slightly larger fish,” says Lippmeier. The DHA gets passed along the food chain, all the way up to the biggest fish.

I just don’t know whether algae in Lake Tai is contaminated, much worse than the case of mercury in fish. 😕

    Very interesting. I’m not sure how tastey that algae looks compared to a dish of salmon. 😉

    People should be aware of both the risks and benefits of seafood. The decision of what fish to eat can be a challenge and often contradictory. At the very least, people should know that FDA and EPA have issued advisories about mercury contamination in commonly-sold fish. The problem is, this information is hard to find and is not usually available where it is most necessary: your supermarket.

    Oceana, a conservation group, is trying to get major grocery companies to post this government advice at their seafood counters. Thanks, in part to their work, Whole Foods, Safeway stores, and Wild Oats voluntarily agreed to post the FDA’s recommendations and they have had positive responses from customers and no loss in seafood sales. But other companies like Costco and Giant Eagle have refused to do so. Oceana has a list of which companies care about their customers’ health enough to post this advice, as well as a list of companies that don’t. You can get the Green List and Red List at their website.
