碩士 / 國立臺灣海洋大學 / 水產養殖學系 / 96 / Three experiments were conducted to find out the effects of dietary astaxanthin and illumination on growth, pigmentation, prey, feeding, and burying behavior of kuruma prawn Marsupenaeus japonicus: I. Effects of Dietary astaxanthin and illumination regime on growth and chromatophores of kuruma prawn, II. Effects of light sources on the catchability of kuruma fry preying on pigmented Artemia nauplii, and III. Effects of light sources on growth, feeding, burying behavior, and pigmentation of kuruma prawn. Fluorescent light was used in Exp. I and 7 light sources in Exp. II and III: halogen light, incandescent light, fluorescent light, white, red, green, and blue light of light-emitting diode (LED). Results in Exp. I showed that the long illumination regime favored prawn’s growth and chromatophores’ color towards blue. Dietary astaxanthin deepened chromatophores’ chroma and their hue towards red. Exp. II showed that kuruma prawn fry could use their vision to prey Artemia nauplii and the catchability was affected by light sources and prey’s body color; combination of white LED and dark red Artemia nauplii enriched by dietary astaxanthin at 120mg/kg for 24 h favored the most for the preying. Exp. III showed light sources and bright or dark regime affected burying behavior and feeding condition and concomitantly, growth of kuruma prawn. Prawn under halogen light and fluorescent light had better growth, feeding, and body color than prawn under 3 single color LED lights. Prawn under white LED, incandescent light, and complete dark had the highest exposure frequency and prawn under red and green LED had the highest complete burying frequency. There were positive correlations between exposure frequency and feed intake and between feed intake and growth.
