Abstract: Cladocera Daphnia magna (Straus, 1820) is one of the most important cladocerans having immense ecological and commercial significance. It is an important food for many aquatic organisms. Light intensity may have negative effect on it biological activities. That is why the study investigated the direct effects of full spectrum light with different intensities along with UV radiation on life history traits of single clonal cultured D. magna. Six-well multi plates were employed for rearing single clonal cultured of D. magna which were subjected to five different light and UV intensities respectively, with six replications. The results showed that number of neonate production and survival rate were significantly (p<0.05) affected by the intensities of light. Mortality rate was found significantly higher (P<0.05) under the highest light intensity. The offspring production decreased with increasing light intensity. The study reconfirms the negative effect of UV radiation on parthenogenetic reproduction physiology, growth and survivability of single clonal cultured Daphnia magna.
