In the present study, biomass performance, feed efficiency, and survival rates of shrimp produced in Aquamimicry concept were comparatively evaluated along with conventional water-exchange-systems with -and without the use of settling chamber. Survival rates of shrimps cultured in the Aquamimicry concept were higher (91-92%) than those farmed with water exchange method with (68.6%) or without settling chamber (81%). In the water-exchange method (0.39) and Aquamimicry treated groups (0.32-0.39), apparent FCRs were almost 3-fold lower than the shrimps exposed to water-exchange system equipped with a settling chamber (0.97). Final biomass at harvest were higher in the Aquamimicry groups compared to traditional methods of water exchange with -or without settling chamber. The Aquamimicry group supplied with twice higher pellet-feed, but same amount of rice bran, demonstrated 1.4-fold higher final biomass compared to the less pellet-feed, but same level rice bran supplement group at DOC30. Water temperature (27.28 ± 1.12°C), dissolved oxygen (6.96 ± 0.46 mg/L), and pH (7.65 ± 0.18) were similar in all treatment groups. Minimum total ammonia nitrogen (TAN) of 0.67 and 1.17 mg/L were found in the water-exchange and Aquamimicry treatment with less pellet supply, whereas higher rates of 2.23 and 5.85 mg/L were found for the Aquamimicry group fed twice more pellet-diets and the water-exchange with settling chamber treatment, respectively. The lowest NO2 level (1.84 mg/L) was obtained in the Aquamimicry group with less pellet supply, and the highest NO2 (4.02 mg/L) was found in the Aquamimicry group fed with high pellet supply. Alkalinity were similar in both water-exchange treatment groups either with or without settling chamber. The findings of this study provide useful support for farm managers for improving shrimp production towards more environment-friendly level by less -or even zero water exchange, with cost-effective method supporting population stability and economic improvements for the sustainability of shrimp aquaculture in future.
