During 2013–2016 in Sevastopol Bay, seasonal and interannual dynamics of the population density, age and sex composition, fecundity, and mortality of males and females of O. davisae were studied. A maximum population number (up to 554 ind × 103 m–3) was registered at the end of summer–end of autumn. In this period, the nauplii and early copepodite stages constituted up to 95% of the O. davisae population. During 1–2.5 cold winter–spring months, the population consisted only of females, who were not numerous. |
