Effects of different feeding frequency on Siamese fighting fish (Betta splenden) and guppy (Poecilia reticulata) juveniles: data on growth performance and survival rate

Optimal feeding frequency in aquaculture is vital for the sustainable and economical production of healthy, high-quality fish. This article described the growth performance and survival rate data in the juvenile phase of two commercially important ornamental fish species; Betta splendens (Siamese fighting fish) and Poecilia reticulata (Guppy) reared at different feeding frequency. Thirty days old juveniles of both species were randomly distributed into 12 3 L rectangular plastic tank (n = 10 fish/tank; three replicates per feeding frequency) where they were subjected to four different feeding frequency treatments (1 meal/day (T1), 2 meal/day (Control), 3 meal/day (T2) and four meal/day (T3)) using commercial ornamental fish micropellets for 60 days. The juvenile's weight and length were measured once a week while the number of live fish were recorded daily. The amount of feed intake was also recorded by weighing in the weight of micropellet left after feeding. At the end of the experimental period, the specific growth rate (SGR), food conversion ratio (FCR) and condition factor (K) were calculated for growth performance using the weight, length and feed intake data while the survival rate was calculated using the number of live fish data. Normality test, One-way ANOVA analysis followed by Tukey pos-hoc test were then performed on the data obtained from the calculation of SGR, FCR, K an survival rate. The data presented in this article will aid the rearing process of both species’ juveniles for commercial, experimental and personal usage purpose.
