摘要： This study compared the growth performance, morphological characteristics, meat texture, and nutrient composition of Genetically Improved Farmed Tilapia (GIFT) across three distinct aquaculture systems: the landbased recirculating aquaculture system (RAS Group), the in-pond raceway system (IPRS Group), and the traditional pond aquaculture system (Pond Group). The RAS Group was found to have the highest carcass rate, viscerosomatic index, hepatosomatic index, condition factor, and lowest crude protein content. The Pond Group exhibited the highest muscle hardness, gumminess, and chewiness. Amino acid and fatty acid profiles varied significantly among the aquaculture systems, with the IPRS Group showing higher levels of Phe, Thr, Met, His, Arg, Ala, Gly, Ser, Tyr, TAA, EAA, and NEAA, and the Pond Group having higher saturated fatty acids (SFAs) and lower polyunsaturated fatty acids (PUFAs) compared to the other systems. These findings highlight the significant impact of aquaculture systems on GIFT quality attributes, suggesting that system selection is pivotal for optimizing the growth, health, and marketability of GIFT, with implications for the economic and ecological benefits of GIFT farming.
