U%\bBnO4?|)+'|ZO The ovaries produce two types of steroid hormones, estrogen and progesterone. There are also vascular ganglionic units that contain ganglionic cells, blood vessels, and the nervous system, and are located near or inside the parenchyma cells (Belsare 1973). These follicles vary in size and shape and are joined by connective tissue. They are mostly herbivorous. The posterior-mid-dorsal growth of the epithelium from the posterior of the habenular produces this organ that passes through the anterior surface through the adipose connective tissue. Distributed in India, Myanmar and Pakistsn. Hormones are soluble in water and they act as catalysts. They are usually located near the gallbladder, spleen or pyloric system. Hormones are destroyed after biochemical reactions. Gills are weakly developed. Protein and Polypeptide Hormone: These hormones are made up of proteins or peptides. Findings revealed that the growth of three treated variant length groups was affected negatively by cadmium exposure and showed significantly (P < 0.05) lower average wet weight, body length and condition factor as compared to control groups, while the feed conversion ratio (FCR) increases by increasing the exposure duration. They are smaller in size and their growth rate is slower, e.g. The flesh is very delicious. Family :- CYPRININAE ( Jaws toothless. Chromophobes do not accept any pigments. Due to the presence of two types of cells, it is thought that they are involved in the production of two types of hormones. Enzymes are not destroyed through biochemical reactions. 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. Hormones are secreted from the endocrine glands and transported to certain parts of the body to exert a specific physiological effect there. ; http://www.fishbase.org/Country/CountrySpeciesSummary.php?c_code=356&id=10111, version (12/2013). 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.

The endocrine gland is unanimously referred to as the ductless gland whose secretory substance is released directly into the blood or lymph. Migrations should be cyclical and predictable and cover more than 100 km. These two tissues are so closely related that they are considered together as neuro intermediate lobes. (4) It acts in the same way as the mammalian adrenal medulla, so the chlomafin tissue of the teleost is considered to be a homologous organ of the adrenal medulla of mammals. It respires exclusively by gills and uses its single lung only under stress. SUPER ORDER :- TELEOISTEI ( Bony fish proper). The endocrine glands of the pancreas condense into numerous islets. A.A.
