Separate and combined exposure of roach Rutilus rutilus embryos during the first 38 h after fertilization to magnetic field (500 Hz, 1.4–1.6 µT) and elevated temperature (23°?) causes morphological responses: decrease in mean values of length and weight of the body, increase in the number of vertebrae, and increase in the number of vertebral anomalies and morphological diversity of vertebral phenotypes. Size–weight characteristics and the number of vertebrae in underyearlings are related to the development of anomalies in its backbone. A method for counting of vertebrae in fish with backbone malformations is suggested.
