Efficacy of Probiotics, Growth Promotors and Disinfectants in Shrimp Grow out Farms

摘要

The usefulness of growth prompters and probiotics in maintaining water quality and thereby in enhancing growth rate is described. In the present investigation based on the efficacy of probiotics, growth promotors and disinfectants in shrimp grow out farms at Sali aqua farms located on the southern banks of uppanar estuary at Thennampatnam near Poombukar, Southeast coast of India. Six ponds were selected and divided into three groups’ viz., 2, II and III. 300g of probiotics was applied directly with inner cover of the pack in the pond in front of the aerator. The growth promoters is applied with the ratio of 5g /kg, mixed with quality binder and applied with the feed and dried. Water quality parameters such as temperature, salinity, dissolved oxygen; pH, ammonia and nutrients (nitrate, phosphate and silicate) were mentioning the standard procedures. The survival rate of treatment ponds with higher dosage was 88.1% and lower dosage was 86.8%. Average weight gained for the shrimp that were supplied with probiotics was 15% greater than that of the control pond. The result shows that probiotics plays a vital role in growth, survival and disease resistance of the animal by maintaining good water quality parameters throughout the culture period. So, it can be recommended that the probiotics can be very well utilized for the shrimp ponds to get maximum growth and survival
