Effect of biological variables and capture period on the proximate composition and fatty acid composition of the dorsal muscle tissue of Hypophthalmus edentatus (Spix, 1829)

This study analyzed the chemical composition of the dorsal muscle tissue of Hypophthalmus edentatus, in particular, fatty acids of the lipidic fraction, and its relationship with the biological variables and the capture period. The average values for moisture, ash, protein and total lipids were 63.1...
