The male bears a brood pouch in which the female lays eggs and the latter remain there till they hatch. Estrogen stimulates the growth of secondary sex organs in female fish and promotes the growth of developing ovarian follicles. Assists in electrolyte control and melanogenesis.

The enzyme is made up of globular proteins. The endocrine glands of mammals are more advanced and well-known, but the endocrinology of fish is limited to the effects of hormones on chromatophores, the function of sex cells, the activity of the pituitary and thyroid glands, and the control of osmosis. World Appl Sci J 21:329341. Hormones are soluble in water and they act as catalysts. Thus, the parental care is performed by the male. It's an important food fish found in the south Asia. Fresh Water Fishes Labeo, Catla, Clarias (Magur), Anguilla, Anabas, Mystus. In some fishes, such as Heteropneustes, it helps in respiration.

In Heteropneustes fossilis, Channa punctatus and Clarias batrachus, spontaneous degranulation and degeneration of beta cells occurs. The idea is that the caudal neurosecretory system is involved in the control of osmosis. Barbels extend posteriorly to pelvic fins or beyond to anal fin.

(2) Organs containing exocrine and endocrine functions: In fish, kidneys, gonads and intestines perform such functions. It is interesting to note that in the early development of the embryo, the eyes of these fishes are laterally situated but being a bottom dweller they are shifted towards one side, as an adaptation to water pressure. Based on the origin, the components of the endocrine system are divided into the following: (1) Discrete endocrine glands: Such glands are pituitary (hypophysis), thyroid and pineal. Function: Controls the secretion of thyroid gland. Talwar, P.K. FOIA Epub 2007 Aug 3.

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. Specific physiological and biochemical tests have shown that these two types of hormones are secreted by teleosts but not readily available (Olivereau 1967). Body elongate and compressed; snout broad and spatulate. Disclaimer: Their cytoplasm is AF+. Mystus seenghala is a very important commercial species, con-tributing substantially to the total inland fish production in South Asia. Some researchers have suggested that the stennius particle is a coexistence of the adrenal glands of the spinal cord and they want to establish it as a posterior adrenal gland. . (1) Thyroid hormone plays an important role in oxygen uptake. The secretion from urophys is able to compress the smooth muscles of the ovaries and fallopian tubes of the guppy fish (Poecilia reticulata) and the sperm of the Gallichthys mirabilis.
