Ask Well: Wild Fish vs. Farmed Fish - NYTimes.com

I know eating farm-raised fish is not as healthy as eating wild-caught fish. But is eating farm-raised fish better than eating no fish at all? Also, how often is it advisable to eat farm-raised fish?

Experts have raised concerns about farm raised fish, which in some cases are raised on unnatural diets and crammed into small enclosures that can breed disease, prompting aquaculture operators to rely heavily on antibiotics.

But farming practices are improving, and consumers have a number of healthy and eco-friendly farmed options, said Tim Fitzgerald, a scientist and sustainable seafood expert at the Environmental Defense Fund. He said some merchants set high standards for the farmed salmon and other fish they sell, including the supermarket chains Wegmans and Whole Foods and the producer Verlasso.

A few of the farmed varieties that are produced responsibly are also relatively high in omega 3 fatty acids, the polyunsaturated fats that promote cardiovascular health. They include arctic char, rainbow trout and oysters, he says.
