Description	We comprehensively describe the fecundity and time of embryonic development of the spiny-cheek crayfish (Orconectes limosus). A linear relationship between the female size and ovarian and pleopodal fecundity and production of juveniles at the 3rd stage in spiny-cheek crayfish fecundity was confirmed. The mean value of the ovarian fecundity was found to be 130.8#107.6 (46-505) oocytes. The value of the female gonadosomatic index just before laying was 4.2#1.8% (0.8-7.7%). Pleopodal fecundity reached 217.8#94.9 (95-492) eggs of a mean diameter 1.8#0.2 mm (1.45-2.15 mm). Statistically significant difference was found between the egg numbers carried on individual pairs of pleopods. Mean time from laying to hatching was 46#3.8 days (37-56 days), i.e. 647#39.9 CTU (Celsius Temperature Units = degrees Celsius x days). Mean production of juveniles at the 3rd stage was found to be 135.7#67.24 (15-243) juveniles. The study shows that the spiny-cheek crayfish has higher fecundity and shorter development time in We comprehensively describe the fecundity and time of embryonic development of the spiny-cheek crayfish (Orconectes limosus).
