Extract

The hepatosomatic indices (HSI) of eight groups of Myxine glutinosa with different gonadal conditions are calculated and compared with each other. Female animals with eggs longer than 10 mm differ statistically significant in their HSI from all other groups. The production of a vitellogenetic protein in the liver of Myxine is concluded.
