Application of stable isotope analysis to differentiate shrimp extracted by industrial fishing or produced through aquaculture practices. por Gamboa Delgado, Julián, Molina Poveda, César, Godínez Siordia, Daniel Enrique, Villarreal Cavazos, David Alonso, Ricque Marie, Denis, Cruz Suárez, Lucía Elizabeth

“…Carbon and nitrogen stable isotope values (13CVPDB and 15NAIR) allowed clear differentiation of wild from farmed animals. 13CVPDB and 15NAIR values in shrimps collected in the open sea were isotopically enriched (−16.99‰ and 11.57‰), indicating that these organisms belong to higher trophic levels than farmed animals. 13CVPDB and 15NAIR values of farmed animals (−19.72‰ and 7.85‰, respectively) partially overlapped with values measured in animals collected in estuaries (−18.46‰ and 5.38‰, respectively). …”
