Wild-caught and farmed fish provide different benefits for those considering eating seafood on a vegan diet. Wild-caught fish come from natural habitats and live as nature intended, so they're generally unharmed by human interference. They also have higher concentrations of certain nutrients than farmed fish. Farmed fish have the advantage of being more ethical, since they don't require overfishing, but have the disadvantage of potentially containing more toxins and pollutants. Consider your dietary needs and make sure sustainability is top priority with your choice!
