title: Sexual structure of population and reproduction cycle of Echinogammarus olivii (Crustacea, Isopoda) in the fouling community of Odessa Bay (Black Sea)
abstract: The sexual structure of Echinogammarus olivii (Milne-Edwards, 1830) population in the fouling community of Odessa Bay (Black Sea)has been determined. It is shown that the annual dynamics of sexual structure is conditioned by the peculiarities of the breeding cycle of this species in the coastal fouling community. Throughout the year quantitative prevalence of females over males was recorded. E. olivii breeding process takes place throughout the year. Peakof the breeding of this species falls wit
