Do you eat salmon?
Are you aware of the health benefits of farmed oysters?
Do you know the famed rainbow trout?
Do you like bluefin tuna?
Do you eat Grouper?
Common conclusions
The general impression is that tuna is high in mercury, hence not suitable. While this is true, an exception is Albacore tuna, the white tuna that gets canned. These fishes are caught in the U.S or British Columbia and are caught with a troll or a pole. This goes to show that these fishes are typically small, weighing less than 20 pounds. Further, they have low mercury levels because they are caught in the cold waters of the north.
Salmon is one of the healthiest fishes available today as it is loaded with omega-3 and omega-6 fatty acids. But these fishes also contain incredibly high levels of mercury because of ocean contamination. The only exception is the wild salmon caught off the waters of Alaska. Biologists are located at river mouths to ensure that they are of the highest quality. Further, there is a limit on how many fishes can be caught, so the ones available tend to be healthy.
Farmed oysters are incredibly healthy as just a three-ounce oyster can contain about 300mg of omega-3 acids. These oysters are farmed in the right conditions to make them beneficial for consumption. The good news is that these oysters are environment friendly because they feed off the nutrients present in water, including the algae, and in the process, clean the water and make it fit for consumption. That said, some people are allergic to raw shellfish, so that's something to watch out for.
Trout is one of the most commonly consumed dishes in the world. Unfortunately, they are steeped in contaminants, too, and tend to do more harm than good for those who consume them. The rainbow trout is an exception, especially the ones grown in the U.S, as they are farmed in protected waters. These farmed fishes are also known to conserve the environment as they are fed a fish-based diet.
Bluefin is one of the most caught fishes globally, and unfortunately, this is also why it is hard to find now. This is why a bluefin tuna can fetch around $177,000 a fish. Furthermore, environmental organizations are fighting hard to protect these fishes, so they become increasingly hard to find. It is time you start looking for other options, mostly farmed fishes, as they tend to be more environmentally friendly.
Grouper fishes contain the highest mercury levels, so EDF has issued a consumption advisory. These fishes also tend to reproduce only for a short time in their lives, making them vulnerable to overfishing.
a Good idea. Consider other fishes that are farmed than caught naturally.
