Description 258-261
Ovarian yolk protein (vitellin) of adult
freshwater prawns Macrobrachium malcolmsonii, M. rosenbergii and M.
lamarreii was characterized, and relationship between the gonadosomatic index
(GSI) and the appearance of specific polypeptides in their ovary during
different stages (early-mature, mature and spent) of reproductive cycle was
studied. Mature ovaries of all the three species showed increased GSI values,
compared to the respective early-mature ovaries. Protein profiles at the three
stages of ovarian maturation were analysed by SDS-PAOE. Polypeptides of low

molecular mass (20 to 70 kDa) were prominent in
the earlymature ovary, whereas in mature ovary, 89 and 100 kDa polypeptides
were predominant. Immunodiffusion studies, using antiserum raised against
purified vitellin from mature ovary of

M. malcolmsonii indicated antigenic similarities of vitellins among the three species.
