The photoperiod is one of the most important factors affecting the feeding strategy, following certain biorhythms, for example, a circadian rhythm. Thus, this work aimed at evaluating the effect of photoperiod and feeding frequency on the uniformity, survival and growth of angelfish (Pterophyllum scalare) larvae. In 40 plastic containers of 1L, 360 larvae (6.9 ± 0.31mm and 3.8 ± 0.08 mg) were randomly assigned in a completely randomized in a 5 x 2 factorial design with four replicates, five photoperiods (0L:24D; 6L:18D; 12L:12D; 18L:6D and 24L:0D) and two feeding frequencies (two or four times/ day). The feed was provided in a proportion of 1000 Artemia nauplii/ larvae/ day for a period of 15 days. The photoperiod only influenced the growth...
