Abstract

The participation of the preoptic post neurohypophysial neurosecretory system in fish breeding was shown by histomorphological, immunohistochemical and electronic microscopical researches. The activation of discharge of nonapeptide neurohormones into blood circulation from posterior neurohypophysis at the beginning of spawning, with the following decrease of functional activity of system after it are revealed in every lumpsum (simultaneous) spawning fishes idependently of its season (for example: Acipenser, Lota, Oncorhynchus). The similar reaction of neurosecretory system is observed morphologically also under the conditions of experimental stress - the containing of the adult acipenseridae fish in hypertonic medium.
