A total of 60 fish of three different length groups (20 each) were collected from Head Qadirabad, Pakistan. It plays a role in controlling physical growth or decline, color, and sexual characteristics etc. Hypophysectomy also results in loss of granules. _____ INTRODUCTION A large number of diseases occur in all aquatic animals including fish. It is histologically similar to the parathyroid glands of the upper vertebrae. These studies have shown that pigment cells, the effect of hormones on germ cells, the function of the pituitary and thyroid glands, balance in movement, nitrogen metabolism (adrenal cortical tissue, thyroid gland), maturation of sex cells and reproductive behavior(pituitary galnd and sex hormones), the effect of hormones on metabolism (adrenal cortical tissue) have been proven. (2011). [3], It grows to a length of 40cm. In Channa punctatus, on the other hand, the cells form small lobules and are arranged along the posterior cardinal vein. in the pineal organ has been found (Srivastava et al. Mystus Mystus is a genus of fish in the family Bagridae native to Asia. Jo. Meso-adenohypophysis: It exists between pro-adenohypophysis and meta-adenohypophysis. Careers. The brain bears relatively small olfactory lobes and cerebellum. In most teleosts, the thyroid gland is composed of numerous follicles surrounding the arterial artery and the afferent bronchial blood vessel. The secretion of interenal tissue is regulated by adrenocorticotropic hormones of the pituitary gland. Classification. Which part of the male reproductive system store the sperm?

Its discovery is of special interest, because it is believed that crossopterygians (fleshy finned fish) were the ancestors of the first amphibians. Mystus: The Cat Fish: Mystus seenghala is a common fresh water cat fish. Content Guidelines 2. On the other hand, endocrine glands do not have any ducts, so endocrine glands are called ductless glands. <>>> (2011): Darshan, A., Mahanta, P.C., Barat, A. 15. These are gastrointestinal peptides that are classified as specific hormones or paracrine agents. Somatropes (STH cells): It is formed from acidophils cells of pro-adenohypophysis and meso-adenohypophysis and is pigmented by orange G. Some species of teleost have two types of acidophil cells. Hypophysectomy and mammalian hormone injections show that the pituitary gland in fish produces nine different types of hormones like mammals. (Two auricles and one ventricle). These glands are located inside and outside the body. Steroid Hormone: This type of hormone is made up of steroid substances. Saliminus, Moxostoma, Labeo. Chromophobes do not accept any pigments. Heydarnejad MS, Khosravian-Hemamai M, Nematollahi A. Ir Vet J.
