title: [Induction of sexual maturation and egg-laying in the prawn Penaeus japonicus Bate in a controlled environment].
abstract: Studies on the endocrine mechanisms which regulate the reproduction processes in the prawn Penaeus japonicus Bate led us to investigate the role of temperature and light; these parameters probably affect the "biological clock" controlling these phenomena. Complete sexual maturation was achieved within a three month period. During the next three months, 72 spawnings from a population of 60 one and two year old females were observed corresponding to 960,000 nauplii.
