The Effects of Different Feeding Programmes on Growth and Survival Rates of Newborn Guppy (Poeciliareticulata PETERS, 1859)

Tolga , Sahin

In this trial, five feeding programmes were used to investigate the optimum feeding process of new-born guppy in five treatment groups. For the study, fish were fed Artemia(nauplii) for 4 weeks (4A), microparticulated feed for 4 weeks(4MF), 1week Artemia+ 3weeks microparticulated feed (1A+3MF), 2weeks Artemia + 2weeks microparticulated feed (2A+2MF) and 3weeks Artemia + 1week microparticulated feed (3A+1MF) in related treatment groups. At the end of the study differences in weight, length, survival and stress resistance of the fish were calculated. According to the measurements, the best average growth of19.94±0.161 mm length and0.0732±0.00120 g weightwas observed in the group fed 4MF (p<0.05), whilst the worst average growth of17.74±0.088 mm lengthand0.0425±0.00061 g weight was observed in the group fed 4A (p<0.05).There were significant differences (p<0.05) in average lengths of18.93±0.038 mm, 18.27±0.055 mm, 17.97±0.025mm in the groups fed 1A+3MF, 2A+2MF and 3A+1MF respectively. The weights did not show any differencewith0.0594±0.00032g and 0.0576±0.00026g between the groups 1A+3MF, 2A+2MF (p>0.05),while the group 3A+1MF showed different live weight of 0.0490±0.00041g (p<0.05) according to other treatment groups. The worst survival rates with %88.14±0.74 has been obtained (p<0.05) in the group fed 4MF while the survival rates has been determined %97.78±0.00 in the group fed 3A+1MF, %97.04±0.74 in the group fed 4A and in the group fed 2A+2MF, %91.85±0.74 in the group fed 1A+3MF respectively. There were no significant differences between the groups fed 4A, 2A+2MF, 3A+1MF (p>0.05) while the groups 4MF and 1A+3MF showed significant differences (p<0.05). According to these results, the diet 4MF and 1A+3MF are not enough for a better aquaculture of new-born guppy. Therefore, it is found in the trial that Artemia supply for the first 2 weeks after birth in guppy are necessary for better survival and stress resistance.
