Eyestalk ablation is an effective technique for artificial induction of maturation in penaeid shrimps. To induce maturation in cultured female kuruma prawn, met hod s of eyest alk a bla tio n and op t imal cond itio ns of p raw ns and of re aring environments were examined. Eyestalk ablation was effective for prawns with developing ovary that were older than 12 months and larger than 140mm in total length. The most successful spawning was seen when prawns had been operated to remove single eyestalks just after molting and were reared at 24℃.
