Performance of Probiotic Bacterium, Enterococcus gallinarum Enriched Artemia franciscana Nauplii on Survival, Growth and Basic Biochemical Constituents of the Prawn Macrobrachium rosenbergii Post Larvae

Growth and survival promotion of a probiotic bacterium Enterococcus durans enriched Artemia nauplii on the prawn Macrobrachium rosenbergii

“…Similar elevations in activities of protease, amylase and lipase have been reported by Jain et al, [39,40] in M. rosenbergii PL fed with E. gallinarum and E. hirae enriched Artemia nauplii. Elevated activities of protease, amylase and lipase have also been recorded in M. rosenbergii PL fed with LactoBasil ® plus, ViBact*, L. sporogenes, Bacillus subtilis, S. cerevisiae, Lactobacillus brevis, Lactobacillus fermentum, B. coagulans and B. licheniformis supplemented feeds [21,22,[24][25][26][27][28][29][30].…”

“…The prepared feed was subjected to proximate composition analysis by adopting AOAC (1995) methodology. The feed proximate composition was as follows: Crude protein, 46.79; Total Nitrogen-free extract, 32.21; Ether extract (Crude fat), 6.19; Crude fiber, 1.33; Ash, 6.81; Moisture, 9.84; Gross energy, 4443 kcal/kg [39,40]. The feed mineral content (%) was as follows: Sand and silica (Acid insoluble ash), 0.83; Calcium, 0.80; Phosphorus, 0.90; Iron, 0.11; Copper, 0.002; Manganese, 0.008; Salt, 0.58 [39,40].…”

“…Nearly half of the tank water was renewed every day and adequately aerated in order to maintain a healthy environment. The unfed feed, faecal material, exuvia/moults, and dead prawns if any were routinely removed by siphoning without disturbing the prawns while renewing the water medium [39,40].…”

“…Similar enhanced growth performances have been reported by following workers. Jain et al, [39,40] in M. rosenbergii PL fed with E. gallinarum and E. hirae enriched Artemia nauplii. Seenivasan et al, [52] in M. rosenbergii fed with Lactobacillus sporogenes enriched Artemia nauplii.…”

“…Enterococcus genus is isolated from the intestine of common carp and freshwater prawn M. rosenbergii [38]. Enterococcus gallinarum and Enterococcus hirae have proved with probiotic functions in M. rosenbergii [39,40] when ingested in sufficient quantities. E. durans possessed quorum quenching activity (ability to grow in low pH) and to produce antimicrobial agents, hence, this bacterium could be used for therapeutics [31,41].…”
