Abstract

Electrophoretic serum protein profile of female Lates calcarifer reveals appearance
of female specific protein during gonadotropic dependent stages of ovarian growth.
The protein is conspicuously absent in the serum of maturing males. The protein
stains positively for carbohydrate, lipids and calcium indicating it to be vitellogenin.
The vitellogenin band first appears in fish with maturing ovaries (stage 3) and
stain intense and sharp till stage 4. At stage 5 (ripe) the band appears diffused.
The protein is lacking in the serum profile of immature (stage 1), restingpreparatory
(stage 2) and spent (stage 6) as well as in maturing male fish. The
correlative pattern of vitellogenin band with ovarian maturation stages provides
evidence of single spawning in L. calcarifer.
