Performance of Black Tiger Shrimp (Penaeus monodon) Postlarvae in Halamphora coffeaeformis Enriched Biofloc Systems

The intensification of shrimp aquaculture has led to challenges such as declining water quality, reduced growth rates, and increased disease susceptibility. Although biofloc technology improves water quality and supports shrimp growth, it often lacks essential polyunsaturated fatty acids (PUFAs), which are vital for shrimp development and immunity. This study investigates the effects of Halamphora coffeaeformis supplementation in a rice bran-based biofloc system on the growth performance, survival, and disease resistance of black tiger shrimp (Penaeus monodon) postlarvae (PL). Four rearing conditions were evaluated: control (clear water with water exchange), BFR0 (H. coffeaeformis only, 1 × 105 cells mL−1), BFR1 (biofloc only), and BFR2 (biofloc supplemented with H. coffeaeformis at 1 × 105 cells mL−1). Shrimp reared in BFR2 exhibited the highest final weight (0.46 ± 0.05 g, p < 0.05), specific growth rate and daily weight gain (DWG), along with superior feed conversion efficiency (1.28 ± 0.13). Survival was significantly higher (95.42 ± 5.77%, p < 0.05) compared to all other groups. Additionally, shrimp in BFR2 demonstrated the greatest lipid (7.08 ± 0.82%) and protein (49.96 ± 1.19%) contents, along with the highest PUFA levels, particularly eicosapentaenoic acid (EPA; 2.88 ± 0.59%) and docosahexaenoic acid (DHA; 0.49 ± 0.26%). Following Vibrio parahaemolyticus exposure, this group exhibited the lowest mortality (64.58 ± 3.43%) and reduced hepatopancreatic damage. These results suggest that supplementing a rice bran-based biofloc with H. coffeaeformis at 1 × 105 cells mL−1 enhances shrimp growth, nutritional quality, and disease resistance, reinforcing its potential as a sustainable aquaculture strategy.
