The connective tissue trabeculae of all islets contain numerous small blood vessels. Classification kingdom Animalia phylum . The climbing perch is a good food fish. The word Endocrine consists of two Greek words Gr., Endo = within, inside and Gr., Crinos = secretion, emission. The flesh is very delicious. Meso-adenohypophysis: It exists between pro-adenohypophysis and meta-adenohypophysis. Numerous nerve fibers originating from the cells of the hypothalamus enter the pituitary gland and re-branch into meta-adenohypophysis. In the lamprey (Cyclostomata) chromafin cells are located along the portal veins of the dorsal aorta, ventricle and heart in the form of a thread. Facultative air-breathing in the genus (Ref. Respiration is supplemented with two lungs. Family :- CYPRININAE ( Jaws toothless. These studies have shown that pigment cells, the effect of hormones on germ cells, the function of the pituitary and thyroid glands, balance in movement, nitrogen metabolism (adrenal cortical tissue, thyroid gland), maturation of sex cells and reproductive behavior(pituitary galnd and sex hormones), the effect of hormones on metabolism (adrenal cortical tissue) have been proven. These follicles vary in size and shape and are joined by connective tissue. Since hormones do not take part in any biochemical reactions, hormones are called autonomous or autocoides. Melanin concentrates to reveal body color. Thus they have bony endoskeleton. The pituitary gland is called the master gland. Classification kingdom Animalia phylum . Bony fishes have a sac-like outgrowth, the swim bladder (also called air bladder), arising from the dorsal wall of the oesophagus, which is air-filled organ, used to maintain balance and to swim up and down. Bony fishes occur in all sort of waters fresh, marine, brackish. Fish measures 15 to 30 cm length and 4 to 5 cm in width. Smith, an eminent Ichthyologist of Rhodes University College at Grahams town.

However, no scientific explanation of this fish therapy is known. 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). In Labeo rohita, Cirrhina mrigala, Schizothorax plagiostomus, the main islet is located near the bottom of the alimentary canal where the bile duct is exposed. Due to the presence of two types of cells, it is thought that they are involved in the production of two types of hormones. Food Control 23:535541. In some species, such as Anguilla and Poecilia, two types of acidophils cells have been distinguished based on location, morphology, and pigmentation capacity. Disclaimer: The NCBI taxonomy database is not an authoritative source for nomenclature or classification - please consult the relevant scientific literature for the most reliable information. Function: Prolactin affects milk production in mammals, but in fish it plays a role in controlling circulation. In Clarias batrachus, Heteropneustes fossilis, and Mystus seenghala, the exocrine glands are more precise, and the largest part is located in the mesentery along the blood vessels or bile ducts between the two lobes of the liver. These cells of urophysis are called caudal neurosecretory system. Biodiversity is the vast array of all species of, EXOCOETUS : FLYING FISH CLASSIFICATION OF FLYING FISH : EXOCOETUS. The nictitating membrane in the eye of fish is well developed. In addition to acidophils, there are some cyanophils that are stained with aniline blue or aldehyde fuchsin (AF). 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. They have 4 pairs of gills which are covered by an operculum on each side. 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.
