Heteropneustes, is a genus of catfish native to Asia. Heteropneustes fossilis is a species, the only one in its family of air sac catfish found in India. It is found mainly in ponds, ditches, swamps, and marshes, but sometimes occurs in muddy rivers. It can tolerate slightly brackish water. It is omnivorous. It is a common air- breathing, venomous fish with its pectoral spines. This species breeds in confined waters during the monsoon months, but can breed in ponds, derelict ponds, and ditches when sufficient rain water accumulates. It is in great demand due to its therapeutic value. It is highly preferred in India and commonly known as singhi. The present study dealt with the observations made on the secretion of vitellogenin during the maturation period, as well as its relational and fractional study in Heteropneustes fossilis.(Bloch 1794)
