title: Differential response to irradiation in offspring of freshwater and seawater substrains of Poecilia (Lebistes) reticulata peters in the "guppy male courtship activity test".
abstract: An inbred strain ("Istanbul") of guppies was divided into two substrains, one of which was maintained and bred in seawater. The offspring of irradiated animals of both substrains (1000 R X-rays to spermatogonia and oogonia of neonatal fish) were tested in a new "gruppy male courtship activity test" and compared with control groups. The postirradiation response in the seawater substrain was more intense than in the freshwater substrain.
