Abstract:
Animals can make adaptive adjustment of selectivity as a function of their own reproductive value which may cause variation in mate choice over the course of reproduction.Here,we examined the mate choice of mated females in the freshwater crayfish Procambarus clarkii.We used a Y-maze,in which mated females made selection between potential mates with different mating status.When faced with primary partners,virgin or unfamiliar mated males and a blank control,females showed significantly preferences for males in terms of the total duration of visits(P<0.05),while they did not differentiate mating status of the potential mates(P>0.05).Females may mate as frequently as possibly out of reproductive success.Besides,we discussed mated female indiscriminating between males’ mating status in terms of their mate preferences.The present study not only provides theoretical basis for reproductive biology and ethology,but it is also of great practical significance to crayfish aquaculture.
