Extensive study and data collection on the pituitary gland: A promising prospect revealed by surveying the fish market during the monsoon season

Because of India's large population, the fish supply demand is increasing daily. Among all fishes, the Indian major carp (Labeo rohita, Catla catla, etc.) is one of the most demanded fishes in India. Indian major carps breed once a year during the early monsoon season (June and July). At that time, the collection of spawns from natural sources is insufficient for our population. To overcome this situation, induced breeding is the most effective process to increase carp culture. IMC bred twice in a season using this method. The first step in this process is collecting and preserving pituitary glands from donor fish. This gland-pituitary extract is later produced and injected into spawn to facilitate spawning. So, in our survey, we know how many pituitary glands are collected daily as well as weekly averages from the survey site and where they are transferred.
