The largest islet in the Tor tor is pin in shape, located near the bile duct. Mystus Mystus is a genus of fish in the family Bagridae native to Asia. These hormones help in the metabolism of proteins and carbohydrates. Few populations are occur in Thailand, but only in the Salween basin. It is located near the pituitary gland. The current study aims to assess the cadmium sub-lethal concentration influence on growth and haematological and biochemical parameters of Mystus seenghala. Editors. 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. Cloaca is absent in bony fishes. (Now this fish is not alive). We suggest you upgrade to a modern browser. Classification. Almost all types of endocrine glands are present in the fish like in the upper vertebrates but their tissue and physiology are not clearly known. Hormones are important regulators that often regulate the metabolism of different types of living cells. Some researchers have identified the pineal gland of fish as a light-sensitive and secretory organ. The trunk and tail bear moderate sized scales. Kidneys are mesonephric. It is found in clear and sluggish rivers and streams. In some teleosts such as Phoxinus, Rutilus and Astyanax, thyrotrophs aldehydes are used to stain fuchsin (AF).

Fish have a pair of testes and ovaries known as gonads. In most teleosts, the thyroid gland is composed of numerous follicles surrounding the arterial artery and the afferent bronchial blood vessel. These are of two types, namely: A1 and A2. FishBase. In Channa punctatus, on the other hand, the cells form small lobules and are arranged along the posterior cardinal vein. These cells contain glycoproteins and are stained by PAS, aldehyde fuchsin (FA), alcian blue and aniline blue. one-third of LC50, for 16 weeks except for the control groups. Yonar ME, Mie Yonar S, spir , Ural M. Dorsal spine weakly serrated on its posterior edge; adipose fin base short, about as long as the rayed dorsal fin base. From an embryonic point of view, this gland develops from the pharyngeal epithelium near the fifth gill arch. It is carnivorous predatory fish feeding exclusively on small fishes, fish fry and prawns. The word Endocrine consists of two Greek words Gr., Endo = within, inside and Gr., Crinos = secretion, emission. Migrating within streams, migratory in rivers, e.g. Various studies have shown that two types of gonadotropes are found in fish which are known as FSH and LH in mammals. (Two auricles and one ventricle).

Froese, R. & D. Pauly (Editors). The endocrine gland is a type of ductless gland made up of different types of tissues and organs that produces and secretes one or more hormones and regulates the physiological functions of other body organs by direct blood flow. 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% . ).Its secretion is called non-hormonal chemicals (such as sweat, milk, sebum, enzymes, etc. The islets in Channa punctatus are located near the spleen and pylorus. Fishes have very close relationship with their environment. 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). Talwar, P.K. These two tissues are so closely related that they are considered together as neuro intermediate lobes. This gland secretes hormones directly on their own and regulates the function of other glands by helping them secrete hormones. Secretin affects the enzyme-carrying juices from the pancreas and accelerates the flow of zymogens. From the current study, it has been concluded that the growth, haematology and biochemical parameters are important indicators of ecotoxicology particularly contamination of the cadmium and health of the fish. Hormones are destroyed after biochemical reactions. Five Mystus species (Figure 1) were collected from various sites of northern Kerala. Dorsal spine weakly serrated on its posterior edge; adipose fin base short, about as long as the rayed dorsal fin base. Ghiasi F, Mirzargar SS, Badakhshan H, Shamsi S (2010) Effects of low concentration of cadmium on the level of lysozyme in serum, leukocyte count and phagocytic index in Cyprinus carpio under the wintering conditions. The large islets that are visible to the naked eye are called the main islets. Froese, R. & D. Pauly (Editors). All have three chambered heart (two auricles and one ventricle). Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal spines: 0; Anal soft rays: 11 - 12. The sexual maturation of fish and the development of gametes take place in the presence of sex hormones. [1] Phylogenetic relationships within this genus are poorly understood, though it has been suggested that there are two major lineages.
