Abstract:
In this study, different feed additives and combinations were applied to the experimental diet of cherry shrimp (Neocaridina davidi) in four different experiments (W: 0.018–0.20 g, 60 days). Trials I, II, and III were conducted in four groups (12 tanks, 0.24 m², 40 L, three replicates), and Trial IV was designed in five groups (15 tanks). For Trials I, II, and III, mannan-oligosaccharide (MOS), bee pollen (P), and ginseng (Panax ginseng) (G) dietary supplementations (0, 1, 2, and 3 g/kg) were applied. For Trial IV, combinations of the best results obtained from the first three trials (MPG0: 0 g MPG/kg feed, M2P1: 2 g MOS+1 g P/kg feed, G2P1: 2 g G+1 g P/kg feed, M2G2: 2 g MOS+2 g G/kg feed, M2P1G2: 2 g MOS+1 g P+2 g G/kg feed) was applied. It was evaluated that different feed additives and combinations did not affect the growth of male shrimp. Trial I: MOS supplemented feeds had a positive effect on the growth of female cherry shrimps. The M2 group showed the highest final weight, weight gain, and specific growth rate, while the best feed conversion ratio was obtained from the M1 group. In Trial II, the P1 group showed the best growth performance compared to the P3 group. In Trial IV, it was evaluated that dietary M2P1G2 can be recommended to the industry to increase the growth in cherry shrimps.
