The present study is the report about the efficacy of Diatomix product on intensive farming systems with Pacific white shrimp (Litopenaeusvannamei), in the brackish water commercial aquaculture pond located at Tanjore District, Tamil Nadu, India. The study was conducted in two rectangular ponds, one used as control and one as experiment. The experiment was conducted for 120 days from 1st June to 28th September 2017. During the harvest time, the shrimp weight was 18.5 gm in control pond and 22.20 gm in experimental pond. Survival percentage was 82% in control pond and 94% in experimental pond. Production yield was 7585 kg yield in control pond and 10434 kg in experimental pond. The total feed usage was 11.5 tons in control pond and 10 tons in experimental pond. The results of this study clearly indicate that Diatoms produced by Diatomix improved FCR (0.95), increased survival rate (14.6%) and maintained all the water quality parameters as well. From the results, the study suggests that, the use of Diatomix in commercial aqua farms will enhance the shrimp and fish production and offer a great success to aquaculture farmers for sustainable practise and profits.
