dc.description.abstract Diaphanosoma celebensis Stingelin is a typical estuarine cladocera, reported for the first time in India from the Mandovi estuary of Goa, India. The results of the study made on the laboratory reared specimens of this species on the life span, neonate production, tissue biochemistry and toxicity of diesel oil have been described in the paper. Variations were observed in the life span and rate of neonate production between individuals of the 1 st and 2 nd generations. Both were found to be relatively higher in the 2 nd generation, although age at primiparity and the size of neonate did not show any variation. The tissue biochemical composition of the fed and starved cladocerans showed marked difference. The protein content in the fed cladocerans was five times higher (18.5 mu g/cladocera) while the carbohydrate content in the starved cladocerans was three time higher (4.4 mu g/cladocera). The calorific content was 120 kcal/g in fed ones as against 57 kcal/g in starved ones. Mortality rate in diesel oil was found to be related with the concentration and exposure time. Mortality was 100% in 0.66 ppm concentration during the experimental period of 8 days. LC sub(50) was calculated to be 0.26 ppm. However, neonate production did not show any particular trend or consistency with concentration of diesel oil.
