Abstract: The study was conducted to evaluate the growth and production performance of shrimp (Penaeus monodon) and tilapia (Oreochromis niloticus) at different stocking ratio in earthen ponds in Bagerhat district of Bangladesh for a period of four months from March to July 2018. The experiment was designed as randomized block design and designated to three treatments based on stocking ratio with three replications. Post larvae and fingerlings of shrimp and tilapia were stocked at a stocking ratio of 3:1, 3:2 and 3:3 in T1, T2 and T3, respectively. Water quality parameters were within suitable ranges for shrimp and tilapia during the culture. Higher growth (29.17 g) of shrimp was achieved in T2 compared to T1 (28.41 g) and T3 (26.38 g). Higher production of shrimp was obtained in T1 (664.79 kg/ha) than those of T2 (630.07 kg/ha) and T3 (485.37 kg/ha). But significantly (p<0.05) higher production of tilapia was found in T2 (1509.63 kg/ha) and T3 (1467.58 kg/ha) than T1 (922.22 kg/ha). However, the combined production and net profit of shrimp and tilapia farming were significantly (p<0.05) higher in T2 (2139.70 kg/ha, BDT 211209.13/ha) followed by T3 (1952.95 kg/ha, BDT 161731.49/ha) and T1 (1587.01 kg/ha, BDT 159445.90/ha). Therefore, concurrent culture of shrimp and tilapia at a stocking ratio of 3:2/m2 may be suggested to disseminate at shrimp farmers’ level for increasing shrimp and fish production as well as high economic profit.
