I prefer my seafood wild caught. It might be more expensive, but I think it tastes better.
I think that unless advertised otherwise, most restaurants would go for the less expensive locally farmed shrimp, as well as other locally farmed seafood.
This is an exposé on the practice of commercial shrimp farming. It is much like the “factory farming” of much of our meat sources, and puts toxins in our food chain that can potentially effect such things as immune systems, liver function, kidney function…the list goes on.
