Abstract

Abstract: We investigated the effects of particular wavelengths of visible light on salt-induced stress in the ornamental cleaner shrimp Lysmata amboinensis (De Man, 1888 ). Na + /K + -ATPase (NKA) activity and levels in tissues (gill, hepatopancreas, and muscle) of heat shock protein 70 (HSP70) and levels of glucose in whole-body fluids were measured for three days after the shrimp were exposed to red (630 nm), green (520 nm), and blue (455 nm) wavelengths of light at two intensities (0.5 and 1.0 W m –2 ) while exposed to various salinities (25, 30, 35, and 40 PSU). The osmolality of whole-body fluids and the nuclear damage in hepatopancreas tissues were also measured. Although all experimental groups showed negative responses to changes in salinity, the groups exposed to green and red wavelengths of light showed milder negative effects than the groups exposed to blue and fluorescent light. There was no difference in the effect of different intensities of light, but green and red light effectively reduced the osmotic stress caused by salinity.
