| Resumo: |
This study aimed to evaluate the influence of photoperiod on juvenile suruvi (Steindachneridion scriptum) in six photoperiods: 24L-0D (L= Light; D= Dark), 18L-6D, 14L-10D, 10L-14D, 6L-18D and 0L-24D. Juveniles measuring 176.8 ± 13.2mm and weighing 60.2 ± 16.0g were distributed in eighteen 150-L aquariums, stocked with 8 juveniles per aquarium. At the end of the study, treatments 24L-0D (105.7 ± 5.8g and 845.9 ±46g) and 0L-24D (93.3 ± 4.9g and 746.4 ± 39.5g) were different (P<0.05) on weight and biomass. Survival (100 ± 0.0%) and length (212.5 ±2.5mm) were the same (P>0.05) in all the treatments. The results showed that suruvi (Steindachneridion scriptum) reached better weight and biomass in extended light periods.
