•The diets of Procambarus clarkiibetween sexes were not significantly different.•Male crayfish occupied a larger isotopic niche than females.•The isotopic niche of males decreased more slowly than that of females.•Double inter-sexual cannibalism occurred in the middle and later periods of integrated rice-crayfish culture.•Inter-sexual cannibalism could reduce inter-sexual isotopic niche overlap and potential competition.
