These follicles vary in size and shape and are joined by connective tissue. These cells are found in the digestive tract. In addition to acidophils, there are some cyanophils that are stained with aniline blue or aldehyde fuchsin (AF). Researchers have studied the structure and function of this organ (Omara and Oguri 1969); Haferz 1972; Srivastava and Dubu 1975; Sastry and Sathynesen 1981, Khanna et al.

Some aerial fish such as Channa punctatus, C. gachua, C. marulius, C. striatus and Heteroneustes fossilis have a dense and covered thyroid gland near the aortic artery (Belsare 1959). However, they are not pigmented with Periodic acid-Schiff (PAS), Alkan Blue or Aldehyde fuchsin (AF). 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. Pathogenic bacteria have the potential to proliferate or maintain them in the aquatic environment. In 1839, a scientist named Stannius first described the presence of this particle in the kidneys of sturgeon as a distinct glandular structure. Although the endocrine glands have similarities with the upper vertebrae, some differences can be observed due to living in the aquatic environment. It is found only in the Burnett and Mary rivers of Queens-land in Australia. They are carnivorous, e.g., Mystus seenghala, Clarias batrachus (Magur), Heteropneustes fossilis (Singhi), Wallago attu (Fresh Water Shark), Rita rita. This has led to its common name climbing perch.

Acceleration of water metabolism, sodium ion retention, electrolyte metabolism. It is thought that this hormone also plays a role in regulating secretion. 1. It is rich in blood vessels. Ledig cells or interstitial cells secrete testosterone, a hormone called androgen, from the interstitial space, the secretion of which is regulated by GTH. . There are three types of thyroid hormones in fish, viz. In some fish, such as Puntius ticto, the interenal cells form a thick granular lump. Cyanophils in this region exhibit negative reactions to Periodic acid-Schiff (PAS), aldehyde fuchsin (AF) and aldehyde thionin. Gills are weakly developed. When she failed to identify it, she sent its sketch to Professor J.L.B. Sudasinghe, H., Pethiyagoda, R., Maduwage, K. & Meegaskumbura, M. (2016): Darshan, A., Vishwanath, W., Mahanta, P.C. Paul D, Sinha SN (2013) Assessment of various heavy metals in surface water of polluted sites in the lower stretch of river Ganga, West Bengal: a study for ecological impact. 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.
