Author(s): E Rammohan Rao, CH Venkatrayulu and V Venkateswarlu

Abstract: The running mortality syndrome (RMS) is a major problem in shrimp Litopenaeus vannamei farming areas, in recent years farmers were facing production losses in shrimp due to this disease. The prevention and control of different diseases in shrimp farming aqua farmers using chemicals and antibiotics. These therapeutic chemical substances create environmental pollution and human health hazards. The herbal compounds are alternatives to chemical drugs for improving the immunity of the cultivable organisms in aquaculture. The commercial herbal feed supplement Phytozoi was applied @ 3g/Kg feed every after 40 days of culture (DOC) upto harvest in P2 and P3 experimental culture ponds compared with control ponds (P1 and P4). The results clearly indicate that the application of phytozoi herbal feed supplement in Litopenaeus vannamei in culture ponds showed increased survival percentages, feed intake, improved water quality, proper molting and also recovered hapatopancreases of the shrimp. The result clearly shows that there was significant (P<0.01) difference in survival percentages and total yields between the experimental ponds when compared to controls. The herbal feed supplement phytozoi may improve the resistance against the running mortality syndrome of shrimp and also offer economic benefits.
