Symbiotic effect of Bacillus clausii and Galacto-oligosaccharide on growth and survival rates in red cherry shrimp (Neocaridina davidi)

In this 30-day experiment, the effect of probiotics (Bacillus clausii, commercial probiotics: Enterogermina) and prebiotics (Galactooligosaccharides, GOS) on growth red cherry shrimp (Neocaridina davidi) has been investigated for 30 days. The trial was conducted with 270 shrimps (initial weight: 0.24±0.03 g) in 27 plastic tanks (volume 0.01 m3 area 0.05 m2) representing 9 groups. Except control group, diets were supplemented either GOS or synbiotics per kg feed as G1 (1g GOS), G2 (2g G3 (3g G4 (4g G1P GOS+ 1 ml probiotic), G2P (2 g G3P (3 probiotic) G4P (4 probiotic). This study showed significantly (P< 0.05) higher rate indices male female fed additives groups compared to group. highest final body weight, weight gain, specific recorded from 2 probiotic 3 Similarly, found synbiotic Conversely, lowest both noted Regarding conversion ratio survival rates shrimps, significant improvements. our study's findings, Bacillus clausii (commercial probiotic: dietary can be used improve rates.
