An integrated approach for rearing Pacific white leg shrimp (Litopenaeus vannamei) with red seaweed Agarophyton tenuistipitatum was evaluated in an experimental-scale in biofloc system. Accordingly, four treatments were designed and assessed the applicability of seaweed in biofloc-based intensive shrimp rearing system with respect to bioremediation and shrimp growth. Chemical oxygen demand, turbidity, NH4-N, NO2-N, NO3-N, and PO4-P was significantly reduced (P < 0.05) in biofloc-seaweed (B-SW) system compared to control and biofloc monoculture system. After 30 days of the experiment removal of NH4-N (93.73%), NO2-N (60.04%), NO3-N (73.38%), and PO4-P (49.06%) in biofloc-seaweed system was found significantly higher than biofloc monoculture system. B-SW could contribute by reducing nitrogen compounds (NH4-N, NO2-N, and NO3-N) and phosphate (PO4-P), turbidity and COD in water, and increase final weight of shrimp and survival percentage (5.50 ± 0.207 g and 74.17 ± 2.21%) compared to control (2.25 ± 0.258 g and 42.33 ± 1.45%) and biofloc system (4.13 ± 0.199 g and 53.33 ± 1.67%). SGR of shrimp was significantly increased by 5.31 ± 0.023% day-1 in biofloc-seaweed system compared to biofloc without seaweed (4.35 ± 0.006% day-1). Incorporation of seaweed was successful to improve water quality and growth of shrimp in biofloc system.Not Available Not Available |
