The current study was carried out to examine the effects of four different experimental salinities (T 1 = 0‰, T 2 5‰, 3 10‰, and 4 15‰) on growth, water quality, proximate composition, total bacterial (TB), hemocyte counts white leg shrimp ( Litopenaeus vannamei ) giant prawn Macrobrachium rosenbergii in biofloc based nursery bi‐culture system for 6 weeks. A 12 cylindrical plastic tanks (125 L) filled up 100 L rearing L. M. post‐larvae (PLs) at an equal ratio: (50 : 50 ). At end experiment, , significantly higher p < 0.05) growth rate recorded (15‰) compared other treatments. For a (5‰) than Similar best feed conversion ratio (FCR) ‐ found while it . Gross return, net profit, benefit–cost (BCR) analysis revealed profit (10‰), (5‰), (0‰). TB were be greater Hemocyte (0‰) (5 ‰), (10 (15‰). Therefore, can suggested that 15‰ salinity will condition system.
