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. [ABSTRACT FROM AUTHOR] |
