Variability in development of bilateral parts of the brain during ontogenesis of roach

Talikina, M. G.; Izyumov, Yu. G.; Komova, N. I.

A study exploiting the gravimetric method did not reveal identical development of paired parts of the roach (<i>Rutilus rutilus</i>) brain. In the studied sample, the proportion of fish with left or right asymmetry of this organ was 1:1. The specificity of fluctuating asymmetry in studied plastic parameter depending on the fish age and growth was analyzed.
