ABSTRACT
A comparative study of the variation which occur in soluble
protein in the testis and pituitary gland ofmale Mugil cephalus in .
both natural habitat (El-Bardawill) and captivity habitat (El-Serw)
during different stages of sexual maturity. by using isoelectric
focusing (lEF) method The electrophoretic patterns of testis and
pituitary gland proteins showed differences in terms ofmaturation
stages. The investigated organ of each habitat has a characteristic
stage – specific and isoelectricfocusing pattems.
