  • The effect of unilateral eyestalk ablation on reproduction, molting and quality of offspring was investigated in Cherax quadricarinatus females during the reproductive-arrest period (winter). At the end of the Autumn, females that had spawned for the first time had relatively uniform, early vitellogenic ovaries, while most females that had spawned previously had ovaries containing two distinctly sized and coloured oocyte populations.
