Abstract
The influence of a commercial probiotic, Ecomarine was tested on the growth performance of post larvae of Indian white prawn, Fenneropenaeus indicus for a period of 90 days in fiber glass tanks (500 liter). There were three treatments and a control for the study. Ecomarine was administered at 15 ppm through water (Treatment 1), a concentration of 5% was supplemented through a commercial feed containing 35% protein (Treatment 2) and a combined supplementation through water and feed (Treatment 3). A control was maintained without administering Ecomarine. Higher growth was observed in juveniles grown in tanks supplemented with Ecomarine through feed and water (Treatment 2) when compared with Treatment 1 and control. There was no significant difference in the ammonia and nitrite concentrations in water between treatments and control. Ecomarine found to enhance growth and survival of post larvae of Fenneropenaeus indicus.
