Abstract: Oogenesis is a very important biological phenomenon to generate haploid reproductive cells, eggs. Basic information on endocrine control of oogenesis in fish has been accumulated by using a variety of methods, such as histological, biochemical and molecular techniques for over 50 years. This monograph describes basic information on physiological functions of ovarian follicles, as sites of steroidogenesis and growth factor production, and also their physiological roles in oogenesis. Application of basic information to artificial hormonal control of eel reproduction is also mentioned.

Keywords: fish, oocyte growth, oocyte maturation, ovulation, ovarian follicle, steroidogenesis, growth factor, hormonal treatment, eel
