Abstract
The growth and survival of Whiteleg shrimp, Litopenaeus vannamei post larvae were evaluated in four different treatment tank assigned as Treatment Bio-Aqua, Treatment Bio-Block, Control-N and Control tank by using four 7-f, aquaria There were 30 tails of L. vannamei post larvae reared in each tank. In Treatment Bio-Aqua and Bio-Block tank, each was treated with commercial probiotics, B-Aqua and B-Block, respectively with the addition of nitrifying bacteria by immersion technique, Control-N tank treated with nitrifying bacteria and control tank had no addition of the commercial probiotics and nitrifying bacteria Each of the treatment was conducted in duplicate. Feeding was given according to shrimp body weight. After a 54-day feeding trial with probiotics supplied through water immersion and additional 9 days of challenging with pathogenic bacteria, Vibrio harveyii by immersion technique, post larvae exhibited significant difference (P<0.05) in term of growth, whereas Treatment BioAqua, Treatment Bio-Block and Control-N had significant (P<0.05) higher growth than control tank. For survival, L. vannamei was not significantly affected (P>0.05) by the treatments. But, Treatment Bio-Aqua, Bio-Block and Control-N have the higher survival rate compared to the control tank. After 62 days of feeding, cultured with commercial probiotics and challenge test with pathogenic bacteria, V. harveyii, the used of commercial probiotics may view as one of the solutions which is available to promote growth and survival besides the use of conventional methods such as anti- biotic and chemicals.
