| Research Abstract |
The objective of this study is to elucidate mechanisms involved in the yolk formation in fish oocytes. Results included development of novel technologies for separation and quantification of multiple subtypes of a yolk precursor (vitellogenin : Vg) ; such techniques were initially developed for the grey mullet, and thereafter applied for several other teleosts. Findings endow the better understandings on fish oogenesis, as well as improvement of fish egg quality in aquaculture and development of technologies for the surveys on the impacts of environmental xenoestrogenic chemicals.
