Lepidosiren (South American Lung Fish): It is found in river Amazon and Paraguay basin in South America. Some islets of carp are also covered by extracellular cells. These glands secrete calcium-regulating hormone calcitosin (thyrocalcitosin). According to Belsare (1983), some teleosts such as Labeo rohita,Cirrhina chirrhosus (= Cirrhina mrigala), Catla catla, Clarias batrachus, Channa punctatus, etc., contain only one type of cell in stennius corpuscles. system. In fish (Heteropneustes, Clarias, Channa) hyperglycemia occurs when glucose is applied and hypoglycemia occurs when insulin is applied, resulting in degradation of beta cells. Sometimes these cells are lightly pigmented with erythrocyte or azocarmine and turn gray with lead hematoxylin. The pectoral spine of the species may give painful wounds and sometimes can be venomous. Amino acid derivatives or biogenic amines: These hormones are derived from amino acids such as melanin and adrenal medullary adrenaline. In Lamprey (cyclostomata), endocrine internal cells are present throughout the body cavity adjacent to the posterior cardinal vein. It undergoes aestivation during summer season. Disclaimer. At fresh condition the lipid content of Mystus tengara, Mystus cavasius, Mystus gulio were 6.15%, 5.98% and 6.20% and after twenty days of it's freezing the observed lipid content were 4.9%, 5.37% . The ovaries produce two types of steroid hormones, estrogen and progesterone. Functions: Arginine plays an important role in controlling vasotocin secretion and maintaining salt-water balance, and oxytocin helps in sexual intercourse and egg laying. Skin has rudimentary scales. Although mammalian endocrinology is more advanced, but studies have been performed on hormone-regulating functions in fish. Bhatt, V.S., S.G. Dalal and S.A.H. Researchers have studied the structure and function of this organ (Omara and Oguri 1969); Haferz 1972; Srivastava and Dubu 1975; Sastry and Sathynesen 1981, Khanna et al. 11. They were Mystus seengte, M. malabaricus, M. montanus, M. oculatus and Mystus armatus. Moreover, some small islets are scattered in the mesentery. The below mentioned article provides biology notes on Class Osteichthyes. Carps have toothless mouth with scales on the body; however, head is without scales. Some teleosts have lymphocytes and migratory cyanophils in this region. Hormones have to rely on certain external stimuli such as light, temperature and water chemistry to function. The idea is that all these heterotropic thyroid follicles migrate from the pharyngeal region to different parts of the body. z4[`\\X#wo~oVd{Xf\aAWaS;s@#e{7hXbd7826 *gM65Blo[7^Ogb")+&y": qT8s J Fish Aquat Sci 5:113119.

Later, the generic name of this species has undergone several replacements (Bagrus, Aorichthys, Mystus) and currently it is placed under the genus Sperata (Ferraris and Runge, 1999). In Carassius fish, it helps in cell melanogenesis. (5) Hormones in the thyroid gland play a role in the metabolism of carbohydrates in fish. This gland is attached to the roof of the Dianecephalon by the infandibulum. Applying thiourea reduces liver glycogen. Function: Such cells help to increase body size. The fish were treated to the sub-le Biota; Animalia (Kingdom) Chordata (Phylum) Vertebrata (Subphylum) Gnathostomata (Infraphylum) Osteichthyes . AF + and AF are found in salmon, Astyanax mexicanus and Anguilla anguilla (Nadkarni and Gorbman 1966, Rasquin 1965, Hanke and Chester Jony 1966).

Fish have more than one islets. Ledig cells or interstitial cells secrete testosterone, a hormone called androgen, from the interstitial space, the secretion of which is regulated by GTH. (1) Thyroid hormone plays an important role in oxygen uptake. In Heteropneustes fossilis, Channa punctatus and Clarias batrachus, spontaneous degranulation and degeneration of beta cells occurs. It also undergoes aestivation. Marine Fishes Exocoetus, Hippocampus, Solea, Echeneis (Sucker fish), Lophius (Angler fish). This is not the case with others. Which part of the male reproductive system store the sperm? This gland secretes hormones directly on their own and regulates the function of other glands by helping them secrete hormones.

There are three genera of living lung fishes: Neoceratodus, Lepidosiren and Protopterus. It controls all the biochemical reactions in the cell. Depending on the change in the salinity of the water, the grouping of cells decreases or increases. However, as a result of the proliferation of multiple branches of the parenchyma (Neurohypophysis), it can be easily distinguished from meta-adenohypophysis. In eel fish, these cells contain more grains which are more pigmented in alizarin and lead hematoxylin. 5. The stannius are covered by the connective tissue capsule and contain a type of AF + secretory cell along the blood vessel. Assists in electrolyte control and melanogenesis. They prepare secretin extract from the intestines of salmon, dogfish and skates.
