Abstract

In Brazil, 47% of the fish farming correspond to the tilapia species, and the main producers are the south and northeast regions. This work aimed at characterizing the amino acid profile of three fishes with the potential for rearing and diversification in Brazil and worldwide. The fishes grass carp (Ctenopharyngodon idella), pacu (Piaractus mesopotamicus), and catfish (Ictalurus punctatus) were obtained from a rural property located in the city of Pato Branco, PR, Brazil, and analyzed regarding the amino acid composition through High-Performance Liquid Chromatography. The amino acid profile showed the presence of glutamic acid, followed by lysine, aspartic acid, and leucine as the most prominent amino acids for the three fishes. Among the studied species, the grass carp presented the highest content of essential amino acids, registering all values superior to the minimum recommendation standards determined by the Food and Agriculture Organization of the United Nations (FAO). The disclosure of the significant nutritional value presented by these species consolidate their protein quality and expand possibilities to improve the fish farming and development of derivative products.
