Coming soon to a supermarket near you? GMO salmon

Now that the FDA has approved production of GMO salmon, here they come.  Next month, a land-enclosed fish farm in Indiana will start raising these fish.

These, you will recall, are salmon bioengineered to grow throughout the year.  They end up much bigger than wild salmon.

These have been a long time coming.  As I’ve written previously,

• The FDA’s approval has been controversial
• The salmon are likely to cause problems for retailers

One big question with farmed salmon is what to feed them.  They need sources of color (there’s a dye, asthaxanthin, for that) and of omega-3 fatty acids (other fish?).

Indiana is the leading soybean-producing state.  Maybe these salmon have a handy food source?
