Abstract: Stimulation of salmon larvae by electric current led further to unstable character of reactions in the open field. Acoustic stimulation both by tonal and musical signals favourably influenced the behaviour in the open field and the ability to elaborate conditioned reflexes. Changes of the content of nucleic acids were not found in the brain tissue but were found in the muscles, where they correlated with the growth speed and motor activity of the experimental fishes. The obtained data show the possibility of elaboration of applied methods of the control of CNS development and behaviour of young fishes at fishing plants.
