Description
Summary:Probiotic bacteria in larvae rearing is expected to suppress pathogenic bacteria and improve water quality. The research aimed to determine the effectivity of probiotic bacteria containing Bacillus subtilis and B. licheniformis on larval rearing of purple mud crab Scylla tranquebarica to produce crablet. The larvae were stocked in nine units of conical fiber tank, fed Rotifers, Brachionus plicatilis , and nauplii Artemia sp. The probiotics tested, namely, A). RICA-4, containing the bacterium Bacillus subtilis , B). RICA-5 containing B. licheniformis , C). A combination of probiotics RICA-4 and RICA-5. The administration of each probiotic with a density of 10 8 CFU g −1 (5 mg L −1 ) was given to the water media for larvae rearing. The lowest nitrite and Total Organic Matter in the zoea stage were found in treatment B. At the megalopa stage, treatment B’s lowest TOM concentration occurred and was significantly different (p
