Resumen o descripción
This research evaluates the effect of wavelengths of the light on growth rates of Nile tilapia fry in
the order of improving sustainability in aquaculture production. For this purpose, four tanks of water with
tilapias were studied. Three tanks were illuminated with LED lamps each one with monochromatic peak
wavelengths (𝜆): Blue light (BL) tank with 𝜆 = 451.67 nm, Green light (GL) with 𝜆 = 513.33 nm and Red
light (RL) tank with 𝜆 = 627.27 nm. All tanks were illuminated with a light intensity of 0.832 𝑚𝑊⁄𝑐𝑚2,
and they had a photoperiod of 18L:6D throughout the study. Besides, the fourth tank was illuminated only
by Natural light (NL) tank, which had the function of witness tank. Each treatment included the fourth, were
randomly assigned to 150L tanks that were stocked with 122 Nile tilapia fry. The Nile tilapia fry had an
initial average weight of 0.24 ± 0.01 𝑔, and were grown for 73 days. The average final weight for BL, GL, RL
and NL treatments were 15.54 g, 16.84 g, 17.27 g and 16.22 g, respectively. The results suggest that Nile
tilapia fry was positively influenced by the red light wavelength, which was represented in the greatest mass
gain.
