Nationwide, seafood consumers are paying close attention to their seafood options and demanding transparency on point of origin. The Louisiana Certified Seafood Program aims to differentiate seafood caught along its coast, as well as in its estuaries, from imported seafood. Major sources of minerals to marine invertebrates are water and feed, which vary with location. Louisiana wild caught brown (Farfantepenaeus aztecus) and white (Litopenaeus setiforus) shrimp collected across the Louisiana coastline were divided into three groups based on catch location. Mineral analysis was conducted using inductively coupled plasma optical emission spectrometry on the tail muscle from each coastal group. In the three groups of Louisiana wild caught shrimp a significant difference was detected in the minerals aluminum, iron, manganese, sulfur, cadmium, potassium, and phosphorus. The ability to identify shrimp catch location based on mineral composition can potentially be used to differentiate Louisiana wild caught shrimp from farm raised or imported shrimp.
