Synergistic Effects of Compound Probiotics (Bacillus + Lactobacillus) and Plant-Derived Extract (CPE) on Growth Performance and Disease Resistance of Litopenaeus vannamei

This study explored the synergistic effects of compound probiotics (CPB: Bacillus subtilis BS-1 + Lactobacillus plantarum LP-2, 2:1) and plant-derived extract (CPE: tea polyphenols + oregano oil, 3:1) on Litopenaeus vannamei. A 12-week experiment (six groups: Control, 0.2% CPB, 0.3% CPE, 0.2%CPB+0.2%CPE, 0.2%CPB+0.3%CPE, 0.02% oxytetracycline (AB); 250 shrimp/tank, initial weight 0.92±0.08 g) was followed by a 7-day Vibrio parahaemolyticus challenge (1×10⁷ CFU/mL). The 0.2%CPB+0.3%CPE group performed best: weight gain rate (456.8±26.3%) was 62.3% higher than Control, and superior to CPB, CPE, and AB groups (P<0.05). It increased gut villus height by 54.2%, reduced gut Vibrio by 70.2%, and enhanced total hemocyte count (+63.0%), lysozyme (+85.2%), and SOD (+58.6%) vs Control. Challenge survival rate (85.3±3.5%) was 2.5-fold higher than Control and 25.4% higher than AB (P<0.05). High-throughput sequencing showed enriched beneficial gut bacteria and upregulated immune pathways. Results confirm the strong synergism of 0.2%CPB+0.3%CPE as an efficient green strategy for sustainable shrimp culture.

Effects of Plant-Derived Extracts (Tea Polyphenols + Oregano Oil) on Immune Function and Vibrio Control of Litopenaeus vannamei

This study investigated a compound plant-derived extract (CPE: tea polyphenols + oregano oil, 3:1 mass ratio) on Litopenaeus vannamei immune function, gut health, and Vibrio control via a 10-week experiment (five groups: control, 0.1%/0.3%/0.5% CPE, 0.02% oxytetracycline (AB); 250 shrimp/tank, initial weight 0.85±0.07 g) followed by a 7-day Vibrio parahaemolyticus challenge (1×10⁷ CFU/mL). The 0.3% CPE group showed the best effects: total hemocyte count (+42.2%), phenoloxidase (+55.0%), and lysozyme (+68.7%) activities (P<0.05), gut villus height increased by 38.5%, and gut Vibrio abundance reduced by 61.4% vs. control. Its challenge survival rate (78.5±3.2%) was 2.3-fold higher than control (34.2±2.8%) and 18.2% higher than AB group (66.4±3.0%) (P<0.05). High-throughput sequencing revealed enriched beneficial gut bacteria (Lactobacillus, Bifidobacterium) and upregulated immune-related KEGG pathways. Results indicate 0.3% CPE is an effective antibiotic alternative for sustainable shrimp culture.

Regulatory Effects of Probiotic Complex Formulations on Gut Health of Litopenaeus vannamei and Steady-State of Aquaculture Environment

This study assessed three probiotic complex formulations (PCF1: Bacillus subtilis + Lactobacillus plantarum; PCF2: B. subtilis + Saccharomyces cerevisiae; PCF3: L. plantarum + S. cerevisiae) on Litopenaeus vannamei gut health and intensive aquaculture environment stability over 12 weeks. Four groups (control + three PCF-supplemented diets: 1×10⁸ CFU/g) were tested in quadruplicate (300 shrimp/tank, initial weight 0.72±0.06 g). Results showed PCF1 significantly improved gut health: villus height (+42.3%), epithelial thickness (+35.6%), and digestive enzyme activities (amylase/protease/lipase +38.7%/+45.2%/+32.6% vs. control, P<0.05). It also reduced total ammonia nitrogen (52.7%), nitrite nitrogen (58.3%), and COD (36.9%) (P<0.05), enriched gut beneficial bacteria (Lactobacillus, Bacillus) while decreasing Vibrio, and enhanced water nutrient-degrading microbes. PCF1 increased shrimp survival (94.2±2.3%) and weight gain (356.8±18.5%) (P<0.05). This study confirms PCF1 as an effective formulation for improving L. vannamei gut health and maintaining aquaculture environment steady-state, supporting sustainable intensive shrimp culture.

Effects of Microalgae Enhancement on Nitrogen and Phosphorus Cycling and Immune Performance of Litopenaeus vannamei in Intensive Indoor Culture Systems

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 showed that CV group significantly reduced total ammonia nitrogen (TAN: 0.32±0.04 mg/L), nitrite nitrogen (NO-N: 0.15±0.02 mg/L) and total phosphorus (TP: 0.28±0.03 mg/L) (P<0.05), compared to control. CV group also enhanced shrimp superoxide dismutase (SOD: 62.3±3.5 U/mg prot) and phenoloxidase (PO: 12.8±0.9 U/mg prot) activities, and increased survival rate (92.5±2.7%) and weight gain rate (312.6±15.8%). High-throughput sequencing indicated CV group enriched functional microbes (e.g., Nitrosomonas, 8.7%; Acinetobacter, 6.5%) related to N/P removal. This study provides a feasible microalgae-based strategy for sustainable intensive shrimp culture.

Optimization of Biofloc Technology for Intensive Pacific White Shrimp (Litopenaeus vannamei) Culture: Effects on Water Quality, Growth Performance and Microbial Community Structure

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 (2.1±0.3 mg/L) (P<0.05), increased weight gain rate (286.4±12.7%) and survival rate (89.2±3.1%). 16S rRNA sequencing revealed dominant genera including Vibrio (12.3%) and Pseudomonas (8.7%). This optimization provides theoretical support for sustainable intensive shrimp culture.

Quantum Sensing, Quantum Optics, and Quantum Information Systems: Advancing Precision and Sustainability in Aquaculture and Marine Biotechnology

Quantum sensing, quantum optics, and quantum information systems—leveraging quantum coherence, entanglement, and photon manipulation—are transforming aquaculture and marine biotechnology by enabling ultra-sensitive monitoring, non-invasive imaging, and secure data transmission. This review synthesizes 2022–2025 research on these technologies for marine environmental management, aquaculture health optimization, and bioprocess innovation. Key applications include quantum sensor-based pathogen detection, quantum optical imaging of larval development, and quantum information systems for secure aquaculture data sharing. We address challenges such as quantum decoherence in seawater and scalability, while highlighting solutions like error-corrected quantum sensors and low-cost quantum optical setups. This work underscores how these quantum systems drive efficiency, sustainability, and resilience in global aquaculture.
