(Now this fish is not alive). The pineal sac is a light-sensitive organ in fish, but it also acts as an endocrine gland. These hormones help in the metabolism of proteins and carbohydrates. Large grains of neurosecretory material are sometimes called herring bodies. In fact, it does not fly but often leaps into the air up to about six metres high. (1) Thyroid hormone plays an important role in oxygen uptake. In sharks and rays (Elasmobranchii) these nerves are located in the sympathetic chain of the nerve ganglia. These form singles or groups within the adrenal cells or form adrenal complexes jointly with the adrenal glands.

Mystus seenghala is a very important commercial species, con-tributing substantially to the total inland fish production in South Asia. (2) The hormone produced from chromaffin tissue concentrates the pigment granule in melanophore. It is a connecting link between fishes and amphibians. Hormones are made up of peptides and proteins or amines or steroids or fatty acids derivatives. The posterior-mid-dorsal growth of the epithelium from the posterior of the habenular produces this organ that passes through the anterior surface through the adipose connective tissue. After performing their activities they become destroyed or inactive or removed. Hormones work especially well on certain organs. in the pineal organ has been found (Srivastava et al. Function: Prolactin affects milk production in mammals, but in fish it plays a role in controlling circulation. The function of this gland is regulated by the pituitary gland. It contains acidophils, cyanophils and chromophobes. Later, the generic name of this species has undergone several replacements (Bagrus, Aorichthys, Mystus) and currently it is placed under the genus Sperata (Ferraris and Runge, 1999).
