Mystus seenghalaare called as sykes due to the presence of barbels. It makes identification taxonomically significant. The epithelium around the follicle may be thin or thick, and the height of the cells depends on their excretory activity. Fecundity of four species of catfishes, namely, Mystus seenghala (Sykes), Mystus cavasius (Ham), Wallagonia attu (Bloch) and Heteropneustes fossilis (Bloch), was studied. Mystus seenghala is a common fresh water cat fish. 1. It regulates the production of pancreatic juice by secreting a hormone called secretin (pancreatozymen). (1) Chief cells These cells are dense and columnar in shape and have transparent cytoplasm attached. Secretin affects the enzyme-carrying juices from the pancreas and accelerates the flow of zymogens. In Heteropneustes fossilis, Channa punctatus and Clarias batrachus, spontaneous degranulation and degeneration of beta cells occurs. Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae Beta cells are usually located in the center of the group of islets, but some fish have two types of cell scattered throughout the islet.

In some species, such cells have a follicular structure. In fish such as Poecilia, these cells are granular long chromophobic types. There are three genera of living lung fishes: Neoceratodus, Lepidosiren and Protopterus. The largest islet in the Tor tor is pin in shape, located near the bile duct. This is because the hormones secreted by these glands directly through the help of different biochemical reactions and reveals various characteristics, as well as play a role in controlling the secretion of other endocrine glands. Thyroid hormone (TSH) is present on the surface of meso-adenohypophysis and in some species of such as Poecilia, gonadotropes are found in the ventral side of meso-adenohypophysis.

In many teleosts, such as Anguilla and Poecilia, the somatotropes are acidophils type and are located in the meso-adenohypophysis and are mixed with thyrotropes. 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. Water quality parameters were kept constant during the entire course of the research, and the major parameters were measured as temperature (28.03 0.03 C), DO (5.82 0.14 mg L-1), pH (8.00 0.01) and total hardness (249.98 0.01 mg L-1). Hormones are secreted from the endocrine glands and transported to certain parts of the body to exert a specific physiological effect there. It is a living fossil which was taken off from the eastern coast of South Africa, on December 22, 1938 by some fishermen. Marine Fishes Exocoetus, Hippocampus, Solea, Echeneis (Sucker fish), Lophius (Angler fish). It is thought that this hormone also plays a role in regulating secretion. This gland secretes hormones directly on their own and regulates the function of other glands by helping them secrete hormones. Thyrotropes cannot be distinguished from gonadotropes in most teleosts.

In Carassius fish, it helps in cell melanogenesis. It is covered by the germinal layer. The tail is homocercal. Large grains of neurosecretory material are sometimes called herring bodies. It feeds on the mosquito larvae; therefore, it is widely used to control mosquito larvae. The pectoral fins are modified into wing-like structures, with the help of which the fish glides. This hormone is synthesized from the anterior region of the small intestine. Adenohypophysis):It is divided into three types: These are: Pro-adenohypophysist: It covers most of the frontal lobes of adenohypophysis. These follicles vary in size and shape and are joined by connective tissue. Numerous nerve fibers originating from the cells of the hypothalamus enter the pituitary gland and re-branch into meta-adenohypophysis. Pinealectomy in Lebistes showed a decrease in their growth rate and abnormalities in the stimulation of the skeletal system, thyroid, pituitary and stennius corpuscles.
