The present work analyses the quality of proteins in aquaculture products, by studying changes in the electrophoretic profile performed by SDS-PAGE, for the sarcoplasmic (SPP) and myofibrillar (MFP) proteins fractions in sea bream (Sparus aurata) issued from different aquaculture farms (A, B and C) of the Northern region of Tunisia. Analysis of the sarcoplasmic fractions didn’t show any significant differences. While for myofibrillar fractions, the principal component analysis (PCA) of densitometric readings showed significant differences (P <0.05) between station C and the two others stations, A and B.Le présent travail s’est intéressé à la qualité des protéines dans les produits aquacoles en étudiant les variations du profil électrophorétique réalisé par SDS-PAGE, des protéines sarcoplasmiques (SPP) et myofibrillaires (MFP) chez les daurades royales (Sparus aurata) issues de différentes stations A, B et C d’élevage aquacole de la région Nord de la Tunisie. L’analyse de la fraction sarcoplasmiques n’a montré aucune différence significative. Alors que pour la fraction myofibrillaire, l’analyse en composante principale (ACP) des lectures densitométriques a permis de révéler une différence significative (P<0.05) entre la station C et les deux stations A et B.
