Photoperiodic induction of ovarian maturation in crayfish Procambarus clarkii is mediated by extraretinal photoreception

The current study was carried out to investigate whether the photoperiodic induction of ovarian maturation in crayfish is based on a photosensitive rhythm related to extraretinal photoreceptors. To test this, two batches of 61 juvenile crayfish Procambarus clarkii consisting of (1) intact organisms...
