Abstract:Recent studies evidenced that some fishes use ultraviolet light in social signalling. Using reflection spectrophotometry we showed that reproductively active male sticklebacks also reflect in the UV-light (300-400 nm). Several body regions showed a reflectance peak in the UV-waveband. Silvery appearing regions reflected stronger than red-coloured or darker ones. Males within one population varied in UV-reflection. The UV-contrast of one particular region was positively correlated with physical condition.
