Adenohypophysis):It is divided into three types: These are: Pro-adenohypophysist: It covers most of the frontal lobes of adenohypophysis. & Barat, A. These follicles vary in size and shape and are joined by connective tissue. The pineal gland secretes melatonin hormone and sulfate acid mycopolysaccharides, basic proteins (proteins arginine and lysine amino acids), common lipids, acidic lipids, phospholipids, basophil-rich neurosecretory components containing gamma components. The pineal sac is a light-sensitive organ in fish, but it also acts as an endocrine gland. Cyanophils is seen as the main ingredient during fish maturation and spawning. The pituitary gland is called the master gland. It is rich in blood vessels. It is a long and lobed organ. AF + and AF are found in salmon, Astyanax mexicanus and Anguilla anguilla (Nadkarni and Gorbman 1966, Rasquin 1965, Hanke and Chester Jony 1966).
