Synergetic effect of probiotic, molasses and immunostimulant supplementation on the production of white leg shrimp Litopenaeus vannamei Boone, 1931

The aim of the study is to find out a suitable combination of supplements for the successful production of shrimp Litopenaeus vannamei. The experiment was performed in two different shrimp farms located in the same area at Athirampattinam (Farm-A) and (Farm-B), Tamil Nadu, East coast of India. Each group consisted of three ponds, farm-A supplemented with probiotic, immunostimulant and molasses. Subsequently, farm-B was supplemented with chemicals and probiotics. The shrimp average body weight (23.2 +/- 0.41 g) survival (84 +/- 0.05 %) and production (6.98 tons/ha) was significantly higher (P < 0.05) in farm-A than the farm-B. The water parameters such as temperature, pH, salinity, transparency, dissolved oxygen, total ammonia, nitrite, total plate count and Vibrio population were significantly varied between these two farms. The safe water quality parameter values were obtained in farm-A. Henceforth, the present study was concluded that the supplementation of probiotic, immunostimulant and molasses combination enhanced the shrimp production.
