摘要：The culture of shrimps received maximum importance due to its unique taste, high nutritive value and persistent demand in the world market. In recent years, the diseases of shrimp hindered the development of shrimp culture. In the present study an attempt has been made to culture the giant tiger shrimp, P. monodon in 12 ponds each with 0.6ha near Vellapallam village of Sirkali taluk, Nagai district, Tamilnadu. The use of probiotic bacteria in aquaculture has tremendous scope and the study of the application of probiotics in aquaculture has a glorious future. In the present study the probiotics, viz., Super biotic, Super Ps, Zymetin and Mutagen was applied in culture ponds ("A" section) of P. monodon which is compared with "B"section ponds without probiotic treatment. Growth and survival rate of the ponds which w as applied ("A " section) with probiotics was higher than that of "B" section ponds. The bacterial population decreased at the end of culture in "A" section ponds, but in "B" section the bacterial population was not showing a significant decrease. Black gill, white gut and fungal diseases were recorded in "B" section ponds. But these diseases were not that much reported in probiotic treated ("A" section) ponds. The general conclusion obtained from the present study is that the probiotic plays a vital role in growth, survival and disease resistance of the animal by maintaining good water quality parameters throughout the culture period. It is clear from the bacterial colony data that green colony dominated only in the "B" section ponds. So it can be recommended that the probiotics can be very well utilized for the shrimp ponds to get maximum growth and survival.
