碩士 / 國立臺灣海洋大學 / 水產養殖學系 / 101 / Having a good body color could motivate the consumers to consume and to enhance the market price. Two experiments were conducted to determine the effects of illumination and background color on growth, feeding and pigmentation of white shrimp (Litopenaeus vannamei) : I. Effects of light sources (halogen, incandescent, T5 fluorescent, T8 fluorescent, green, red of light-emitting diode (LED)) on growth, feeding, and pigmentation of white shrimp. II. Effects of background (black, white, red) on growth, feeding, and pigmentation of white shrimp. Results of Exp. I showed that light sources had no significant (p > 0.05) effect on growth, feeding and survival but effect (p &;lt; 0.05) on body color. No significant was found on light sources of yellowness and hue. Dark had the lowest in lightness and redness but had the highest in chroma. Dark had the deepest body color, the following is green LED but the lightest is red LED. Results of Exp. II. background color had no significant effect on growth, feeding and survival. The deeper is the background color, the deeper is the body color of living shrimp and the more reddish is the body color of cooked shrimp. Therefore, black had the best in body color, the better is the red color and the lightest is white color.
