Hypophysectomy and mammalian hormone injections show that the pituitary gland in fish produces nine different types of hormones like mammals. It is usually located in the posterior part of the kidney and is thought to be an endocrine organ. These glands are located inside and outside the body. Some researchers have identified the pineal gland of fish as a light-sensitive and secretory organ. Bony fishes occur in all sort of waters fresh, marine, brackish. In Labeo rohita, Cirrhina mrigala, Schizothorax plagiostomus, the main islet is located near the bottom of the alimentary canal where the bile duct is exposed. Moreover, estrogen controls the sexual behavior of the female fish. Adenohypophysis):It is divided into three types: These are: Pro-adenohypophysist: It covers most of the frontal lobes of adenohypophysis. National Library of Medicine Hormones thus play a role in regulating circulation, gas metabolism, buoyancy, corticotropin release, and smooth muscle contraction. Adrenal cortical tissue or internal tissue, Along the hemopoietic tissue-cardinal vein of the main kidney. In the wild it is found in Indian Subcontinent countries such as, India, Bangladesh, Pakistan, Sri Lanka, Nepal, and Myanmar.Reports of this species from the Mekong basins, Malaysia, and Indonesia are misidentifications of the species Mystus albolineatus or Mystus singaringan. Normally less active follicles contain thinner epithelium. These form singles or groups within the adrenal cells or form adrenal complexes jointly with the adrenal glands. Adult male and female fishes migrate from river to sea where they lay eggs and die. Hormones are generally of four types, viz. They are found in meso-adenohypophysis. <> Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. Some bony fishes show parental care.

From an embryonic point of view, this gland develops from the pharyngeal epithelium near the fifth gill arch. The endocrine system consists of a number of glands called endocrine glands which are spread over different areas of the fish body. Smith, an eminent Ichthyologist of Rhodes University College at Grahams town. The nervous system and the endocrine system existing in the animal body coordinate the functions of different systems. The sexual maturation of fish and the development of gametes take place in the presence of sex hormones. Sometimes these cells are lightly pigmented with erythrocyte or azocarmine and turn gray with lead hematoxylin. The pituitary gland is mainly divided into two parts based on the cell structure, relative position, presence of secretory cells and pigmentation capacity of different parts of the pituitary gland, viz. The chromafin tissue of the fish is given below: (1) When chromafin tissue extract is injected into other fish, it stimulates the sympathetic nervous system.
