The effect of continuous parthenogenesis on reproduction capacity of Moina mongolica

Moina mongolica continuously reproduced 24 generations through parthenogenetic reproduction in 105 days during which M. mongolica were individually reared in laboratory under constant temperature (25℃),salinity (10), and food condition(3×106cell·ml-1 Chlorella spp.).There was not significant decline in reproduction capacity for the progenies that were parthenogenetically reproduced.74.1% individuals in the experiment reproduced four broods. Time for the first brood was 4.28± 0.37days (mean±SD). Interval between two broods was 2.30 ± 0.41 days within 1 to 4 broods while number of offspring per brood was 7.52±1.39. This experiment indicated that there was not significantly negative effect on reproduction capacity of M. mongolica following 24 generations of continuously parthenogenetic reproduction.
