STUDIES ON CELLS OF PROXIMAL PARSDISTALIS OF PITUITARY GLAND IN RELATION TO GONADAL CYCLE IN FRESHWATER ANABAS TESTUDINEUS

Detailed studies were carried out on the cells of proximal parsdistalis of the pituitary gland of Anabas testudineus through out the year. Different cell types in the proximal parsdistalis were studied. Quantitative changes were observed in the cells as they are associated to the maturation of gonads of fish. It is concluded that the percentage to basophils is maximum with maximum secretory activity during the spawning period. It confirms the secretion of basophils is directly related with gonadal maturation.
