Study of the sexual maturity of female bluefin tuna : Purification and partial characterization of vitellogenin and its use in an enzyme-linked immunosorbent assay

Plasma steroid levels of female bluefin tuna (BFT) Thunnus thynnus rose from c . 1.5 ng ml super(-1) during the quiescent period (March) to c. 7 ng ml super(-1)during the ripening period (May). Testosterone (T) increased further to c. 8 ng ml super(-1)during the pre-spawning period (June) while 17 b...

Zusammenfassung:Plasma steroid levels of female bluefin tuna (BFT) Thunnus thynnus rose from c . 1.5 ng ml super(-1) during the quiescent period (March) to c. 7 ng ml super(-1)during the ripening period (May). Testosterone (T) increased further to c. 8 ng ml super(-1)during the pre-spawning period (June) while 17 beta -oestradiol (E sub(2)) began to decrease. In the post-spawning period (August) steroid levels decreased to
