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