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

Abstract

The aim of the study is to find out a suitable combination of supplements for the successful production of shrimp <em>Litopenaeus vannamei. </em>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 (<em>P < 0.05</em>) 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 <em>Vibrio</em> 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.
