Abstract
Asphalt and copper acetate are shown as chemical inductors which can enhance maturation of ova and increase vitellogenesis in the two genera of teleostean fishes,Clarias batrachus andOphiocephalus punctatus.
Along with the study of their effect on the ovaries, changes seen in the pre-optic nucleus of these fishes have also been studied. It is brought out that a distinct correlation exists between the ovarian activity and the fuchsinophil content of the neurons of the pre-optic nuclei of these two fishes.
Copper acetate is seen to hasten enlargement of a large number of oocytes while asphalt increases their yolk content. It is also noticed that in the eggs with more yolk the granulosa is prominent.
