In a chronical test guppies were incubated in the darkness in diethylnitrosamine-concentrations of 26 and 100 mg/1 up to seven months. This treatment led, because of the toxicity of the compound, to lesions in organs of the peritoneal cavity. Tumors were not observed. The cause of the lack of carcinogenic activity is discussed.
