1. Atlantic cod. The issue with Atlantic cod is all about the ecology and the fish population, rather than your health. The Atlantic cod fishery failed in the late 1990s after being aggressively fished for a thousand years. Fishing for Atlantic cod has been drastically curtailed since then, but the species has struggled to recover. Scientists concur that the collapse of the fisheries has profoundly altered the North Atlantic food cycle, making the species vulnerable to extinction .

2. Atlantic flatfish (including halibut, flounder, and sole). This is another example of overfishing and general waste. In commercial fisheries, “wasted bycatch” occurs when a fish or other marine species is caught unintentionally while catching other fish. Every year, US fisheries dump over 2 billion pounds of wasteful bycatch overboard. This is comparable to approximately half a billion meals! The California gillnet fishery, which targets halibut, has been classified as one of the worst, and any halibut you’ve eaten in the United States is likely the result of this operation .

3) Caviar. Caviar are the eggs of the Beluga Sturgeon, an ancient fish capable of living for a hundred years. Its eggs are highly sought after and can fetch thousands of dollars per pound. As a result, this unique species is now extremely vulnerable to extinction . This also applies to many other varieties of Sturgeon.

4. Chilean bass. In terms of the environment, this is another species that has been severely overfished. Furthermore, its high mercury level puts human health at risk .

5. Eel. This is one fish you might want to skip on the sushi menu. Eels mature slowly and have been overfished in many places of the world, leading to population collapses. This is problematic since eels contribute significantly to the spread of mussel populations, which operate as natural water filters [7]. Furthermore, eels absorb and store hazardous chemicals and contaminants very well. This is such a concern that in some locations, residents are recommended to consume eel only once a year .

6. Imported Basa, Swai, Tra, and Striped Catfish. In many circumstances, these fish are simply labelled as “catfish” and should be avoided. According to a 2016 study, 70% to 80% of these fish were contaminated with Vibrio Bacteria, which is responsible for the majority of shellfish poisoning cases .

7. Imported Farmed Shrimp. Pesticides are widely utilized in shrimp cultivation around the world. All but one of them are prohibited in the United States. Furthermore, these shrimps have frequently been treated with significant amounts of antibiotics, so any time you handle these raw shrimp, you run the danger of becoming sick with antibiotic-resistant bacteria.
