Effect of soil probiotics in the shrimp culture.

The role of probiotic bacteria in small culture is studied but commercial level is not that much reported especially in giant tiger shrimp, P. monodon. Hence the beneficial effect of probiotics on the commercial culture of Indian major candidate shrimp, P. monodon is studied in a grow out pond. The farm is located on the Northern bank of Uppanar estuary in Maravakadu. An effort was made to evaluate the differences between regular and irregular application of soil probiotics in the P. monodon shrimp farming. Subsequently the performance of using probiotics frequently and the total average yield attained was 1900 Kg /0.5ha. With maximum growth increment of 34.70g, survival of 90.31%, achieved at the DOC 130. Level of ammonia found nil for the entire culture period in the regularly probiotics used ponds. Contrarily, in irregular treated ponds the total yield achieved only 1150 Kg /0.5 ha. With the maximum growth of 27.29 g, survival of 70.68% at the DOC 130 respectively. The level of ammonia found 0.3 mg /L. [ABSTRACT FROM AUTHOR]
