Ecdysteroids and ovarian development in the shore crab, Carcinus maenas.
Mature ovaries of the shore crab Carcinus maenas contain large concentrations of three major ecdysteroids which we have identified by physicochemical methods as ecdysone, 20-hydroxyecdysone and ponasterone A. The fluctuations of ovarian and blood ecdysteroid concentrations are presented in relation to the various stages of ovarian development.
