Effects of Long-Afterglow Phosphorescent Pigments on Somatic Growth in Juvenile Goldlined Spinefoot Siganus guttatus

Abstract

The purpose of the present study was to examine effectiveness of light emitted by long-afterglow phosphorescent pigments (LAPP) on the somatic growth of juvenile goldlined spinefoot. Comparison was done between juveniles in the aquarium with LAPP (exposure group) and those in the aquarium without LAPP (control group). When juveniles were reared under these conditions for more than 1 month, relative increasein somatic growth and average of specific growth rate of the juveniles (1-month-old, but not 9-month-old) in the exposure group were significantly higher (P
