Amino acid and bioactive signatures of yellowfin tuna loins: ocean-specific patterns across major fishing grounds (opens in new tab)

BackgroundTunas are among the most valuable and consumed fish worldwide. In 2022, global tuna landings reached 8.3 million tonnes, with Yellowfin tuna (Thunnus albacares; YFT) representing 18.8% of the total, and ranking fifth among the most landed finfish. This study tested three null hypotheses: H01: Total protein content and the amino acid composition do not vary between geographic origin; H02: Bioactive compound profiles do not differ among regions; H03: There are no compositional differe...
