This is yet another example of overfishing and waste. Commercial fisheries produce what’s known as “wasted bycatch,” which occurs when fish or other marine species are unintentionally caught while targeting different species. Every year, U.S. fisheries discard approximately 2 billion pounds of bycatch, which is the equivalent of half a billion meals! The California gillnet fishery, which focuses on halibut, has been singled out as one of the worst offenders. If you’ve eaten halibut in the U.S., there’s a good chance it came from this fishery.
3. Caviar
Caviar comes from the eggs of the Beluga Sturgeon, a centuries-old fish that can live for up to one hundred years. These eggs are in high demand and can fetch thousands of dollars per pound. As a result, the Beluga Sturgeon is now at great risk of extinction. The same threat applies to many other sturgeon species as well.
4. Chilean Bass
Its high mercury content poses a health risk to humans
5. Eel
Eels are slow to mature and have been overfished in many parts of the world, causing some populations to collapse. This is problematic as eels play an important role in spreading mussel populations, which act as natural water filters . In addition, eels absorb and store harmful chemicals and pollutants very easily. This is such a problem that in some areas residents are advised to eat eel no more than once per year.
6. Imported Basa, Swai, Tra, Striped Catfish
These fish, in some cases, are simply labeled “catfish”, and should be avoided. According to a 2016 study, seventy to eighty percent of these fish were contaminated by Vibrio Bacteria, which is what causes most cases of shellfish poisoning
