Abstract

The effect of prostaglandin Ej and follicle stimulating hormone on oogenesis was studied in the freshwater
prawn, Macrobrachium lamerrii. The ovaries of the base control and experimental control were
small and white in colour and their gonosomatic indices were 1.06 ± 0.27 and 1.50 ± 0.24 respectively.
Histological observations indicate that base control ovaries showed oogonia, primary oocytes and few
primary vitellogenic oocytes. Primary vitellogenic oocytes with proliferating zone were noticed in
experimental ovaries. In prostaglandin E2 treated group the colour of the ovary changed from white to
green and the gonosomatic index increased to 4.08 ± 0.6. Secondary vitellogenic I, II and few primary
vitellogenic oocytes were observed.
The ovaries of FSH administered group were light green in colour and the gonosomatic index was
3.12 ± 0.40. Active proliferation of oocytes, few primary vitellogenic and secondary vitellogenic-I oocytes
were observed.
