Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

The Aquaculture Dilemma

Posted by feww on October 14, 2007

UPDATE: Eat Fish! Don’t Eat Fish!

Here’s the aquaculture (fish farming) dilemma: Farmed fish are safe to eat; wild fish are NOT. To produce 1 kg (2.2 lbs.) of farmed fishmeal, the fish are fed about 5 kg (11 lbs.) of smaller wild fish.

[Note: It takes about 20 kg of wild fish (also known as pelagic, open-ocean, or “trash” fish) including anchovies, mackerel and sardines to produce 1 kg of high protein ranched tuna.]

Aquaculture’s intense reliance on wild fish for feed poses significant ecological risks. Aquafarms pollute the environment with tons of fish feces, antibiotic-laden fish feed, and diseased fish carcasses.

There are other collateral problems created by industrial scale aquaculture: the destruction of coastal habitats through waste disposal, the introduction of diseases and the possible escape of exotic species that can threaten indigenous breeds.

    Hello Melissa
    Thanks for your comments. Also, the fundamental question we ought to ask is: by what right do the polluters poison our oceans and the fish habitat?

    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 Wal-Mart, Costco, and Giant 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.
