ZAFRA TRELLES, Alina Mabel et al. Experimental growth of Oreochromis aureus at different photoperiod in a closed system, Trujillo-Peru. Arnaldoa [online]. 2023, vol.30, n.1, pp.79-88.  Epub 30-Abr-2023. ISSN 1815-8242.  http://dx.doi.org/10.22497/arnaldoa.301.30105.

The research on the experimental growth of Oreochromis aureus at different photoperiods in a closed system was carried out in Trujillo, Peru at the Aquaculture Laboratory of the Universidad Nacional Trujillo. The seed was obtained from the La Balsa Module and the experimental growth of O. aureus was evaluated with three photoperiod treatments T1-24: 0, T2-12: 12, and T3- ​​natural photoperiod in an indoor closed system. The growth in length and the average weight of the tilapia was 106,28 mm and 23,18 g in T1, in T2 102,69 mm and 21,55 g, and T3 102,69 mm and 21,55 g in 128 days of aging. It is concluded that the growth of O. aureus was slightly higher in the photoperiod of T1-24: 0 without presenting significant differences in the treatments.
