The aim of our study was to optimize the implementation of biofloc technology system (BFT) by proposing a polyculture that integrates sea cucumber (Holothuria inornata) into shrimp (Penaeus vannamei) culture. We evaluated the polyculture of P. vannamei and H. inornata (UR‐SSC) in the same culture unit. In addition, both species were cultured in separate units with recirculation (R‐S and R‐SC) at a density of 500 shrimps/m³ and 12 kg/m³ of sea cucumbers in 100‐L tanks. Cultures with recirculation were subsequently evaluated in 300‐L tanks for P. vannamei (500 shrimps/m³) and in 100‐L tanks for H. inornata (4.5 kg/m³). The results of the first experiment in the UR‐SSC polyculture revealed a survival rate of 80% (FCR 0.6) for shrimp and 40% for sea cucumbers. Survival rate for these species submitted to recirculation was 92% (FCR 0.80) for shrimp and 75% for sea cucumbers. In the second experiment, the shrimp in R‐S and R‐SC revealed a survival rate of 98% (0.69 FCR) and 93% (0.71 FCR), while the sea cucumber exhibited 100% survival rate. The production yield for shrimp in R‐S and R‐SC was 98% (0.69 FCR) and 93% (0.71 FCR) of survival rate, and 100% for sea cucumbers. Our results indicate that P. vannamei presents a satisfactory productive yield when grown under a recirculating polyculture system with H. inornata. Additionally, the survival of sea cucumbers remains unaffected under this culture system.

在生物絮凝系统中白虾（Penaeus vannamei）和海参（Holothuria inornata）的混养

我们研究的目的是通过提出将海参（Hoholthuria inornata）整合到虾（南美对虾）中的混养来优化生物絮凝技术系统（BFT）的实施。我们在同一培养单元中评估了南美白对虾和in。H. inornata（UR-SSC）的混养。此外，两种鱼都在单独的单元中进行循环养殖（R-S和R-SC），在100-L的水箱中以500虾/ m ³和12 kg / m ³的海参密度养殖。随后在300 L的南美白对虾（500虾/ m ³）储罐和100 L的inornata储罐中对再循环的培养物进行评估。（4.5kg / m ³）。UR-SSC混养中的第一个实验的结果表明，虾的生存率为80％（FCR 0.6），海参的生存率为40％。提交再循环的这些物种的成活率对虾为92％（FCR 0.80），对海参为75％。在第二个实验中，在R‐S和R‐SC中的虾的存活率分别为98％（0.69 FCR）和93％（0.71 FCR），而海参则显示100％的存活率。R‐S和R‐SC虾的成活率为98％（0.69 FCR）和93％（0.71 FCR）的成活率，海参为100％。我们的研究结果表明，凡纳滨对虾在带有循环虫的循环混养系统中生长时，表现出令人满意的产量。。此外，在此培养系统下，海参的存活率不受影响。
