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.
