The idea is that all these heterotropic thyroid follicles migrate from the pharyngeal region to different parts of the body. However, as a result of the proliferation of multiple branches of the parenchyma (Neurohypophysis), it can be easily distinguished from meta-adenohypophysis. 1. The anterior end of the pituitary gland is adjacent to the optic kyazma and the posterior end is located in the saccus vasculosus. It is an excellent food fish. 11.82% : 1 Catla-catla 35 04 08 0.18 .

Beta cells are polyhedral-shaped cells with large spherical nuclei. The larvae are so transparent that they are called glass fishes. Gambusia is also called larvicidal fish. Share Your Word File They were Mystus seengte, M. malabaricus, M. montanus, M. oculatus and Mystus armatus. They are separated by connective tissue and surrounded by fibrous capsules. The sexual maturation of fish and the development of gametes take place in the presence of sex hormones. The current study aims to assess the cadmium sub-lethal concentration influence on growth and haematological and biochemical parameters of Mystus seenghala. Pathogenic bacteria have the potential to proliferate or maintain them in the aquatic environment. Fish measures 15 to 30 cm length and 4 to 5 cm in width. Their cytoplasm is AF+. Gonadotropes (FSH and LH cells): These cells are usually present in meso-adenohypophysis, but sometimes, especially during the sexual maturity of eel (Olivereau 1967) and trout (Baker 1968), these cells enter pro-adenohypophysis. All the islets are covered by the epidermis and are seen in the pancreas as small swellings. Beta (B) cells in the cells are involved in the secretion of insulin and in aldehyde fuschin (AF) pigment, it shows a dark purple. Intermediate conditions are observed in Clarias batrachus. First three were collected from Wayanad and remaining ones were from Trichur. The connective tissue trabeculae of all islets contain numerous small blood vessels.

Some researchers have identified the pineal gland of fish as a light-sensitive and secretory organ. However, as a result of hyperglycemia, beta cells are destroyed by taking beta-cytotoxic drugs such as aloxacin and streptozotocin. Enzymes are secreted from the exocrine glands. Recent studies have shown that potential areas and cell types are responsible for the release of these hormones. Thus, the parental care is performed by the male. Initially, Sykes (1839) described this species as Platystoma seenghala. (4) Anterior lobe or region-Pro-adenohypophysis. Mystus ngasep, a new catfish species (Teleostei: Bagridae) from the headwaters of Chindwin drainage in Manipur, India. & Barat, A. They have 4 pairs of gills which are covered by an operculum on each side. The neck and the head of the fish are horse-like and the tail is prehensile. Gills are weakly developed. 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. 5. It regulates the production of pancreatic juice by secreting a hormone called secretin (pancreatozymen). The below mentioned article provides biology notes on Class Osteichthyes. Meso-adenohypophysis cannot be precisely distinguished from pro-adenohypophysis. https://doi.org/10.3923/jfas.2010.113.119, https://doi.org/10.5829/idosi.wasj.2013.21.3.71192, https://doi.org/10.1016/j.foodcont.2011.08.027.

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. It differs greatly in the extent of chromafin tissue (adrenaline-producing) in teleost. Mystus seenghala is a common fresh water cat fish. Water . In different fish, the pineal sacs vary in size and shape. The duration of exposure was 30, 60, 90 and 120 days. Cyanophils is seen as the main ingredient during fish maturation and spawning.

Five Mystus species (Figure 1) were collected from various sites of northern Kerala. The trunk and tail bear moderate sized scales. Bony fishes have well developed renal portal system. The pectoral spine of the species may give painful wounds and sometimes can be venomous. Its size varies widely among different species. 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. Fishermen brought the specimen to Miss Courtenary Latimer, Curator of the local museum. Operculum present. Studies have shown that when the thyroid gland is activated, the concentration of glycogen in the liver decreases. (2016). Assists in electrolyte control and melanogenesis.
