The recirculating pond aquaculture system (RPAS) consisted of culture ponds, a purification pond, inflow ditch, outflow pipe, ecological ditch, and electrically driven pump. The performance of RPAS on grass carp (Ctenopharyngodon idellus) was explored in this study. In both the RPAS and the traditional pond aquaculture system (TPAS), water quality, fish growth performance, muscle quality, and tissue biochemical properties were assessed. Pond water was exchanged every seven days in RPAS and treated using a purification system that included an ecological ditch and a purification pond with a floating bed and aquatic plant. In RPAS, nitrate‑nitrogen, ammonia‑nitrogen, and nitrite‑nitrogen concentrations were lower than in TPAS. Fish cultured in RPAS exhibited significant higher growth rate and lower feed conversion rate. A significant increase in the expression of growth-related genes of myogenin (MyoG), myofactar-5 (Myf-5), insulin-like growth factor-I gene (igf-1), insulin-like growth factor-II gene (igf-2), and growth hormone receptor gene (ghr) were found in the fish cultured in the RPAS ponds. The content of malondialdehyde in either serum or liver and hepatic protein carbonyls content declined significantly in the RPAS ponds. The activities of T-SOD and GSH in liver and GSH in serum elevated significantly in RPAS fish. Muscular histological characteristics and texture profiles did not alter between two groups. The muscular contents of aromatic amino acids of aspartic acid and glutamic acid were significantly higher in RPAS than those in TPAS. It is inferred that RPAS is beneficial to promote fish growth, decrease oxidative stress, and increase muscle umami flavor.

循环塘养殖系统（RPAS）由养殖池、净化池、进水沟、出水管、生态沟和电动泵组成。RPAS对草鱼（Ctenopharyngodon idellus ）的性能) 在本研究中进行了探索。在 RPAS 和传统池塘水产养殖系统 (TPAS) 中，对水质、鱼类生长性能、肌肉质量和组织生化特性进行了评估。RPAS 中每 7 天更换一次池塘水，并使用包括生态沟渠和带有浮床和水生植物的净化池的净化系统进行处理。在 RPAS 中，硝酸盐氮、氨氮和亚硝酸盐氮浓度低于 TPAS。在 RPAS 中养殖的鱼表现出显着较高的生长速度和较低的饲料转化率。生长相关基因myogenin（MyoG）、myofactar-5（Myf- 5）、胰岛素样生长因子-I基因（igf-1 ）的表达显着增加)、胰岛素样生长因子-II基因( igf-2 )和生长激素受体基因( ghr )在RPAS池塘养殖的鱼中发现。RPAS 池塘中血清或肝脏中丙二醛的含量和肝脏蛋白质羰基化合物的含量显着下降。RPAS鱼肝脏中T-SOD、GSH和血清中GSH的活性显着升高。肌肉组织学特征和纹理轮廓在两组之间没有改变。RPAS组肌内芳香族氨基酸天冬氨酸和谷氨酸含量明显高于TPAS组。推测RPAS有利于促进鱼类生长，减少氧化应激，增加肌肉鲜味。
