When it comes to eating the fish of the Amazon River, gamitana (Colossoma macropomum) is one of the most sought after due to its tasty flesh. Also known as tambaqui or giant pacu, the gamitana is a large bass-like fish that can weigh almost 100 pounds.

Yes, you can eat fish from the Amazon, and it is a central part of the regional diet, but there are important safety and environmental considerations in 2026. The Amazon Basin is home to over 3,000 species of fish, including the delicious Tambaqui, the massive Pirarucu (often called the "cod of the Amazon"), and various species of Piranha, which are commonly served in soups or grilled. However, a significant concern for travelers is mercury contamination caused by illegal gold mining (garimpo) in certain tributaries. Mercury bioaccumulates in predatory fish like the Peacock Bass (Tucunaré), making them potentially hazardous if consumed in large quantities. To eat safely, it is best to consume "herbivorous" or "omnivorous" fish, which typically have lower mercury levels. Additionally, ensure the fish is sourced from sustainable, legal fisheries to help preserve the biodiversity of the river. When visiting local markets in Manaus or Iquitos, look for fish that is fresh-caught and properly chilled, and always follow local advisories regarding specific river sections that may be affected by seasonal pollution or mining runoff.
