碩士 / 國立臺灣海洋大學 / 水產養殖學系 / 99 / The marketing price of atydae shrimp(cherry shrimp, Neocaridina denticulata) is greatly influenced by its pigmentation, which is directly influenced by changes in chromatophores.In this thesis, effects of background lightness, hue, illumination period and wavelength on the pigmentation of chromatophores in atydae shrimp are investigated, which include:I. The effect of background lightness on the state of chromatophores and pigmentation of atydae shrimp under three types of backgrounds (black(B), gray(G), white(W) ) with white light illumination, and the change of chromatophores when changing the background color repeatedly.II. The effect of background hue on the state of chromatophores and pigmentation of atydae shrimp under four types of backgrounds (red(R) , yellow(Y), green(Gn), blue(Be)) with white light illumination.III. The effect of background hue on the state of chromatophores and pigmentation of atydae shrimp under three types of illumination period ((0 hour light and 24 hour dark (0L24D), 12 hour light and 12 hour dark (12L12D)).IV. The effect of background hue on the state of chromatophores and pigmentation of atydae shrimp under seven types of illumination source (fluorescence lamp (FL), LED white (LW), LED red (LR),LED yellow (LY), LED green (LG)LED blue (LB), LED violet (LV)).The experimental results indicate that:Lower background lightness is more advantageous to the pigmentation of atydae shrimp.Compare with other types of background hue, a better pigmentation could be obtained under the red background, followed by the yellow background, and then the blue and green backgrounds.The illumination period have no effects on chromatophores and the pigmentation of which in atydae shrimp.Different illumination source have no effects on chromatophores and the pigmentation of which in atydae shrimp.Based on above results, it is indicated that the pigmentation of atydae shrimp is mainly influenced by the background color below, wherein the background lightness mainly affects the pigmentation. Under different backgrounds with a same lightness, better pigmentation effect is achieved under a red background. In addition, the illumination conditions above have no effect on the pigmentation.Therefore, the price of atydae shrimp could be elevated if it is cultured in a black environment before selling. In the case that color other than black is used as background, a red background is preferably used. Furthemore, the pigmentation of atydae shrimp would not be affected during packaging and transportation even the illumination period or source changes.
