Six color treatments Yellow light (Y), Green light (G), Blue light (B), Blue light to Yellow light (BY), Blue light
to Green light (BG), Green to Yellow light (GY) were tested to determine if light color change can promote
the growth of Litopenaeus vannamai. After a 45-day experiment, shrimp in BG treatment showed the best
weight gain (WG) and the specific growth rate (SGRd), which might have been caused by high food conversion
efficiency (FCEd), lowest energy allocation for respiration and highest energy allocation for growth. The
molting frequency in GY treatment was the highest, but the growth was not the best. These results suggest
that the periodic fluctuation from blue region of the spectrum to green region of the spectrum could promote
the growth of L. vannamei and this periodic light color fluctuation may be used as a pattern of regulation of
light color in the commercial shrimp culture.
