This study optimized biofloc technology (BFT) parameters for intensive Litopenaeus vannamei culture. Three carbon sources (molasses, wheat bran, glucose) and two C/N ratios (15:1, 20:1) were tested in 90-day indoor trials. Water quality indicators, shrimp growth performance and microbial communities were monitored. Results showed molasses at C/N 20:1 significantly reduced ammonia-N (32.6±1.8 mg/L) and nitrite-N... more

This study explored the effects of three microalgae species (Chlorella vulgaris, Nannochloropsis oculata, Phaeodactylum tricornutum) on nitrogen (N) and phosphorus (P) cycling, and immune performance of Litopenaeus vannamei in intensive indoor culture. A 10-week experiment was conducted with four groups (control: no microalgae; CV: C. vulgaris; NO: N. oculata; PT: P. tricornutum) in triplicate. Results... more
