title: Seasonal variations in the cyanophils of the pituitary gland in correlation with reproductive cycle of Channa striatus (Bloch).
abstract: Seasonal changes in the cyanophils of the proximal pars distalis of the pituitary gland of C. striatus are conspicuous, and they closely follow the reproductive cycle. There is a poor concentration of their glycoproteinaceous contents during the resting phase and higher concentration during the maturation phase. The cyanophils also undergo a process of hypertrophy, granulation, followed by degranulation and vacuolisation during the spawning phase. They almost empty their contents during the post-spawning period.
