    Resumen

    The distribution of krill females of the different maturity stages was considered to reveal the preferable bottom depths for the spawning. Calculations based on the three expanded scientific surveys and numerous data from observers revealed no statistically reliable tendency in the gravid females to move offshore to deeper waters. The possible reasons causing the spawning females distribution are discussed. It is assumed, that the most important factor determining gravid females distribution is food supply.
