Experimental evaluation of probiotics as biocontrol/bioremediation in the rearing of shrimp (Penaeus monodon)

Abstract

Two hundred fifty-liter (250-L) fiberglass tanks each equipped with 15-L capacity filter tanks are adequate for screening of commercial probiotics. The application of some commercial probiotics in the culture water is more advantageous than adding it to the feeds. Probiotics A, C, and F, when added to the culture water, gave significantly different (P<0.05) average body weights (ABW) and survival rates (SR) of shrimp (Penaeus monodon) compared with other treatments. Probiotics B, D, E, and G when added to the culture water had higher ABWs but were not significantly different (P>0.05) from the other treatments. SR when Probiotic G was added was significantly different (P<0.05) from the control. The results of this study showed that one should be cautious in the use of commercial probiotics because not all are effective. Users should also take note of the active ingredients in the product they buy.
