Abstract

|
A photoresponse that results in organisms dispersing from a region of bright light, generally termed photodispesal, is frequently observed in some fishes notably including mud fish (Misgurunus mizolepis GUNTER). The primary assumption for this study was that the photodispersion may result from the behavioral strategies of the fishes aimed to avoid illumination conditions that could injure the cells in skin tissues via photodynamic sensitization reaction. Here we present some preliminary results that seem to support this assumption: (1) the locomotive action of dark-adapted mud fish was triggered by the onset of illumination with light; (2) blue light (380w∼480 ㎚) was much more effective in bringing about the locomotive activity than yellow (λ$gt;480 ㎚) and red (λ$gt;660 ㎚) lights; (3) two blue light absorbing pigments, which photogenerate activated oxygen species, were separated from the skin tissues of mud fish, one of these being identified as riboflavin.
