Catfish in Spanish Rivers Explained: Species, Names, Danger Levels, and Hotspots
By Sophia Al-Mansoor
Catfish terminology takes on direct financial consequences at the fish market. Unlike parts of the American South or Southeast Asia where catfish is a culinary staple, native Spaniards rarely eat *siluro*. Large specimens accumulate significant loads of heavy metals and microplastics, while their thick, fatty meat has a muddy taste that does not suit traditional Mediterranean cooking.
Cheap imported catfish frequently lands on restaurant plates disguised under misleading labels. Investigations by food safety monitors and investigative outlets have exposed widespread fish substitution in urban markets. A major BBC report revealed how budget chip shops and cafeteria chains frequently pass off inexpensive imported catfish, primarily Vietnamese swai or iridescent shark (*Pangasianodon hypophthalmus*), as cod or haddock.
In the Spanish culinary world, this imported catfish is sold as panga or filete de panga. You will rarely see it advertised as *pez gato* on a Spanish seafood menu, as diners associate the word with poor-quality river mud. Across Latin America, however, wild-caught river *bagre* commands genuine culinary respect. In Colombia's Magdalena River basin, slow-cooked *bagre en salsa* stands as a beloved regional dish, demonstrating that culinary attitudes toward the fish depend entirely on the species and the culture serving it.
